        <p>The paper examines the key economic and institutional factors that determine the participation of developing countries in global value chains (<abbrev xlink:title="global value chains" id="ABBRID0E6C">GVCs</abbrev>). To assess the impact of a number of factors on the foreign value added in export of developing countries, an econometric model for 84 countries for the period 1999-2018 is used. Obtained results indicate that developing countries with higher per capita income, more developed manufacturing industry, more open economy, less administrative burden on business and those actively engaged in foreign direct investment (<abbrev xlink:title="foreign direct investment" id="ABBRID0EDD">FDI</abbrev>) activities demonstrate higher upward participation in the <abbrev xlink:title="global value chains" id="ABBRID0EHD">GVCs</abbrev>. It is also shown that trade liberalization and investments in foreign production strengthen the positions of developing countries in the <abbrev xlink:title="global value chains" id="ABBRID0ELD">GVCs</abbrev> in the long term. Based on these findings, recommendations are formulated for the state policy of these countries in order to accelerate their integration into more complex stages of the <abbrev xlink:title="global value chains" id="ABBRID0EPD">GVCs</abbrev>.</p>

      <title>Introduction</title>
      <p>International trade had been the main form of international economic relations since time immemorial but only in XV-XVI centuries it came into focus of researchers’ attention. The Age of Discovery and the rise of manufacturing brought about the first theoretical concepts explaining the causes and effects of trade relations between countries. Yet, for several centuries after that, most theories, including mercantilist, classical and neoclassical, had treated international trade exclusively as the exchange of finished products, which was a natural view as all business operations involved in the production of final goods were carried out within national borders. Later, in the 1960-1970s international outsourcing of parts and components allowed transnational corporations (<abbrev xlink:title="transnational corporations" id="ABBRID0ETE">TNCs</abbrev>) from developed countries, mainly in the automobile industry, to organize their production processes across borders: this is considered the reference point for the emergence of <abbrev xlink:title="global value chains" id="ABBRID0EXE">GVCs</abbrev>. Yet, it was only in the 1980s, when the growing globalization of the world economy together with liberalization of capital flows and ICT revolution created favourable conditions for <abbrev xlink:title="global value chains" id="ABBRID0E2E">GVCs</abbrev>’ expansion on a truly global scale and the share of intermediate products in international trade began to grow dramatically.</p>
      <p>Global value chain is a form of internationalization of business activities characterized by splitting production process into separate stages carried out in different countries. It is based on cross-border production agreements between enterprises that are either part of the TNC’s network or independent producers. The motives for creating GVC are diverse: access to natural resources, increased production efficiency, market expansion, and others. <xref ref-type="bibr" rid="B10">Krugman and Helpman (1985)</xref> point out that concentration of entire production process in one place reduces costs of coordination and management whereas fragmentation of production facilitates the leveraging of resource price advantage that results in lowering total production costs. <xref ref-type="bibr" rid="B8">Jones and Findlay (2000)</xref> emphasize the importance of access to raw materials and intermediate products produced in other countries for organization of domestic industrial production and trade.</p>
      <p>There are two types of participation in GVC: participation on the production side (the descending component) and participation on the consumption side (the ascending component). The former is typical of countries integrated into raw material stages of the production process. Such countries are mainly suppliers of intermediate goods and services to the world market. The degree of top-down participation in GVC is measured as the share of domestic value added in the value of exports of other countries’ products that were made using these goods and services. The second type participation means that the country purchases intermediate products from abroad for the production of finished products. In this case manufacturers of final goods within GVC framework demonstrate upward participation. An indicator of such participation is the share of foreign value added in the value of domestic exports generated by these products.</p>
      <p>The shift to geographically fragmented production processes opened up great opportunities for companies from various countries to participate in <abbrev xlink:title="global value chains" id="ABBRID0EMF">GVCs</abbrev>. It is important to note that this reorganization of international production has created prospects for participation not only of advanced countries but developing countries as well. This work focuses on the analysis of developing countries’ involvement in <abbrev xlink:title="global value chains" id="ABBRID0EQF">GVCs</abbrev>.</p>
      <p>Although developing countries generally demonstrate low participation rate in <abbrev xlink:title="global value chains" id="ABBRID0EWF">GVCs</abbrev>, most of them have been actively joining in the <abbrev xlink:title="global value chains" id="ABBRID0E1F">GVCs</abbrev>’ activities over the past few decades. This is a good chance for them to enter international markets via joint production and thus secure sustained growth and development of the national economy. At present, the character of integration into <abbrev xlink:title="global value chains" id="ABBRID0E5F">GVCs</abbrev> varies across developing economies: countries of Sub-Saharan Africa and South America are mostly integrated into production chains at the primary stages with low levels of product diversification and internal value added. The developing countries of Southeast Asia are actively involved in the processing of raw materials and assembly of industrial goods. Malaysia, the Philippines and Thailand assemble computer and electronic equipment. China, Singapore and the Republic of Korea produce components for mechanical engineering products assembled in advanced countries. Indonesia is the major supplier of raw materials to the Asia-Pacific value chains (WTO, 2011). Over time, developing countries are striving to improve their positions in <abbrev xlink:title="global value chains" id="ABBRID0ECG">GVCs</abbrev> in order to gain more economic benefits from international fragmentation of production.</p>
      <p>The most significant conjunctural factor determining the character of countries’ participation in <abbrev xlink:title="global value chains" id="ABBRID0EIG">GVCs</abbrev> over the past few years is the COVID-19 pandemic. It is possible to identify at least three channels of its impact on the global supply chains (<xref ref-type="bibr" rid="B5">Fu, 2020</xref>). Firstly, it is the disruption of transport and logistics systems. For the globally dispersed production, stable and timely logistics is a must since a failure at any of its stages jeopardizes all subsequent activities along the chain. Secondly, the pandemic crisis led to reduction in supply of many products because of job closures, social distancing and restricted movement of people and goods. Thirdly, the pandemic had a negative impact on the activities within <abbrev xlink:title="global value chains" id="ABBRID0EQG">GVCs</abbrev> due to a sharp decline in demand. Thus, Asian chains producing clothing and electronic equipment suffered badly as the garment factories in Bangladesh and Sri Lanka and electronics factories in Southeast Asia faced massive cancellation of orders both from advanced and developing countries. It is important to note that developing countries, especially low-income ones, were hit hardest by the consequences of the COVID-19 pandemic, which is not surprising: production in these countries is dominated by industries that require significant physical contact of workers, such as agriculture and mining. Besides, digital infrastructure and digital competencies are not sufficiently developed in these countries and shifting activities online was often impossible.</p>
      <p>The purpose of the study is to assess the impact of selected economic and institutional factors on the ascending-type participation of developing countries in <abbrev xlink:title="global value chains" id="ABBRID0EWG">GVCs</abbrev>.</p>
      <p>The paper consists of four main sections. Section 1 is a review of literature on developing countries participation in <abbrev xlink:title="global value chains" id="ABBRID0E3G">GVCs</abbrev> including the impact of the COVID-19 pandemic on <abbrev xlink:title="global value chains" id="ABBRID0EAH">GVCs</abbrev> in developing countries. Section 2 presents the data and specification of the econometric model used by the authors. In Section 3 we describe the tests carried out to check the reliability of the data. The results of the model evaluation and their interpretation are offered in the final section, followed by the main findings and practical recommendations.</p>

      <title>Literature review</title>
      <p>Today there is no universal approach to the task of explaining what determines the degree of a country’s participation in global supply chains. The way countries integrate into <abbrev xlink:title="global value chains" id="ABBRID0EKH">GVCs</abbrev> is influenced by country-specific factors, such as geographical location, natural resource endowments, national income, economic structure, the nature of trade and economic integration agreements, openness of the economy and availability of physical and human capital. Among these factors it is possible to identify those common to countries with similar levels of development, e.g., the developing countries.</p>
      <p><xref ref-type="bibr" rid="B11">Lopez-Gonzalez (2016)</xref> found that the greater the volume of domestic demand in developing countries, the higher is the probability of their integration into <abbrev xlink:title="global value chains" id="ABBRID0EUH">GVCs</abbrev>. This factor is the most significant for large economies such as India and China, which, being the most densely populated countries in the world, are important sales markets for firms in many industries. <xref ref-type="bibr" rid="B16">Stringer and Ge (2010)</xref> have shown that, in response to the growing demand for agricultural products in South America, the agro-industrial <abbrev xlink:title="transnational corporations" id="ABBRID0E3H">TNCs</abbrev> from New Zealand are actively investing in the region, locating service segments of food value chains there and creating the base for food exports to other regions.</p>
      <p>The degree of developing countries’ participation in <abbrev xlink:title="global value chains" id="ABBRID0EDAAC">GVCs</abbrev> is also impacted by the nature of the trade policies in the <abbrev xlink:title="foreign direct investment" id="ABBRID0EHAAC">FDI</abbrev> recipient countries. It is well known that <abbrev xlink:title="transnational corporations" id="ABBRID0ELAAC">TNCs</abbrev> prefer more open economies with minimal trade barriers to expand the geography of activities beyond the domestic market. Given the growing international fragmentation of production, the competitiveness of final product producer substantially depends on the import of intermediate goods and services. Protectionist barriers, therefore, undermine the development of <abbrev xlink:title="global value chains" id="ABBRID0EPAAC">GVCs</abbrev>. <xref ref-type="bibr" rid="B15">Slany (2019)</xref> investigated the impact of export and import tariffs on value-added trade within the region using a sample of 37 African countries over the period of 2006-2012. The author found that high import tariffs on intermediate products and capital goods along with export tariffs on raw materials hindered the development of regional value chains in Africa. Other obstacles including costs of intra-continental trade associated with lengthy customs checks, long distances between the main logistics centers, and weak transport infrastructure make it difficult to fragment production process in the region. The author concludes that in African countries integration into regional and international supply chains requires efforts to liberalize trade on the whole continent.</p>
      <p>Many studies confirm the essential role of institutional quality in ensuring participation of developing countries in <abbrev xlink:title="global value chains" id="ABBRID0EZAAC">GVCs</abbrev>. The efficiency of public administration, rule of law and anti-corruption policies facilitate international investment in the developing countries striving to join <abbrev xlink:title="global value chains" id="ABBRID0E4AAC">GVCs</abbrev>. Poor institutional quality reduces the potential for the country’s participation in global production networks. Natsuda et al. (2010) note the crucial role of the garment industry in Cambodia’s economic development in the 1990s. The industry was created mainly by <abbrev xlink:title="transnational corporations" id="ABBRID0EBBAC">TNCs</abbrev> with the newly industrialized countries of Asia and China as parts of their <abbrev xlink:title="global value chains" id="ABBRID0EFBAC">GVCs</abbrev> in production of clothes. However, in recent years this industry has been losing investment attractiveness because of the weak state institutions, high level of corruption and increasing activity of trade unions.</p>
      <p>Today, the expansion of <abbrev xlink:title="global value chains" id="ABBRID0ELBAC">GVCs</abbrev>’ activity in developing countries increases the demand for skilled labor in most of them. <abbrev xlink:title="transnational corporations" id="ABBRID0EPBAC">TNCs</abbrev> reinforce this trend by implementing professional development programs in the host economies. Farole et al. (2018) have used empirical data to show that there is a growing demand for skilled labor in the primary sector in such countries. <xref ref-type="bibr" rid="B14">Shepherd and Stone (2013)</xref> found a positive and statistically significant relationship between the number of skilled workers and the presence of firms involved in international activities in developing countries.</p>
      <p>We should mention the role of public policy in developing countries aimed at promoting participation in <abbrev xlink:title="global value chains" id="ABBRID0EZBAC">GVCs</abbrev>. <xref ref-type="bibr" rid="B7">Gereffi et al. (2019)</xref> maintain that transition from import-substitution to export-oriented industrialization in Costa Rica in the 1980s and 1990s was one of the factors that helped the country attract high-tech <abbrev xlink:title="foreign direct investment" id="ABBRID0EBCAC">FDI</abbrev> in assembly production on its territory. In 1998 Intel opened a factory for the assembly and testing of integrated circuits for electronic products to be exported to the United States. <xref ref-type="bibr" rid="B1">Arnold et al. (2016)</xref> show that India’s reforms in the 1990s aimed at liberalization of banking, transport, telecommunications and insurance sectors had very important outcomes. One of these was that Indian industrial firms gained access to a wide range of foreign service providers, which allowed them to benefit from economies of scale due to international fragmentation of production. Overall, it stimulated the rise of manufacturing industry in India. In China, according to <xref ref-type="bibr" rid="B22">Zeng (2019)</xref>, since the 1980s, its special economic zones (<abbrev xlink:title="special economic zones" id="ABBRID0ENCAC">SEZs</abbrev>) have contributed to strengthening the country’s position in the <abbrev xlink:title="global value chains" id="ABBRID0ERCAC">GVCs</abbrev> and thus promoted its industrialization. The strong national government together with advanced knowledge and technologies brought to the country by foreign <abbrev xlink:title="transnational corporations" id="ABBRID0EVCAC">TNCs</abbrev> have led to the significant expansion of China’s participation in the <abbrev xlink:title="global value chains" id="ABBRID0EZCAC">GVCs</abbrev>. Other developing countries may find it worthwhile to study and use this experience.</p>
      <p>The COVID-19 pandemic had a particularly evident impact on <abbrev xlink:title="global value chains" id="ABBRID0E6CAC">GVCs</abbrev>’ activity. The rapid spread of the new coronavirus in the world economy sharply exposed the interdependencies and vulnerabilities of national economies and companies formed over the past thirty years. It caused serious violations and in some cases complete disruptions of global supply chains. There is ample research analyzing the critical changes in <abbrev xlink:title="global value chains" id="ABBRID0EDDAC">GVCs</abbrev>’ functioning triggered by the new coronavirus pandemic and its implications for fragmented mode of production.</p>
      <p><xref ref-type="bibr" rid="B2">Bisson and Hambleton (2020)</xref> look into the impact of the COVID-19 pandemic on regional and global value chains in West Africa. Agri-food chains proved to be the most vulnerable to the pandemic as the market closures and curfews had made it difficult or impossible to transport food from rural areas to cities, which led to rising food prices and the loss of livelihoods of those employed in the agricultural sector. In countries like Gambia, Liberia, Mauritania, Senegal, Sierra Leone prices of agricultural products jumped by 10-20% (<xref ref-type="bibr" rid="B2">Bisson and Hambleton, 2020</xref>). Since agriculture accounts for almost half of all jobs in West Africa, the COVID-19 pandemic caused a significant rise in unemployment. Disruptions in West African food supply chains still threaten food security both in the region and in many developed countries linked to West Africa via agrifood chains.</p>
      <p><xref ref-type="bibr" rid="B17">Teijlingen and Hogenboom (2020)</xref> analyze the effects of the COVID-19 pandemic on commodity supply chains in Latin America. They point out that even before the coronavirus crisis, Latin America had been experiencing economic and political instability caused by the heavy dependence of the region’s economy on exports of minerals, oil and agricultural products: the average annual economic growth rate in Latin America between 2014 and 2019 was about 0.4% (<xref ref-type="bibr" rid="B17">Teijlingen and Hogenboom, 2020</xref>). Then the COVID-19 pandemic severely hit the supply chains of mineral and agricultural raw materials in the region. As global commodity prices plummeted after the pandemic outbreak, many Colombian and Peruvian mining companies went bankrupt, and farms sold their livestock and reduced crop production. Moreover, Latin America’s main partners in primary sector trade – China and the US – decreased their demand for raw materials, which further deepened the economic crisis in the region.</p>
      <p>One of the Southeast Asian countries worst affected by the COVID-19 pandemic is Indonesia. According to <xref ref-type="bibr" rid="B3">Dekker (2020)</xref>, the lack of timely and adequate response to the current situation from the central government and uncoordinated actions of local authorities aggravated the economic crisis in the country. The author notes that this had the greatest impact on Indonesia’s participation in Asian agricultural supply chains: domestic export-oriented palm oil production stagnated because of decreased consumption of this product in key Asian markets and quarantine-induced disruptions in the work of maritime and ground transport led to a sharp reduction in cross-border supplies of palm oil. At the same time, the mining industry demonstrated high resistance to the pandemic; as a result, in recent years Indonesia has been vigorously expanding its operation on the markets for ferrous and non-ferrous metals. Diversification of consumer markets has provided some stability to export activities.</p>
      <p>The analysis of the main factors that contribute to developing countries’ participation in <abbrev xlink:title="global value chains" id="ABBRID0EDEAC">GVCs</abbrev> reveal their different nature. While some of them are determined by the specifics of the overall macroeconomic, political and institutional environment of the host countries, others are shaped by the purposeful state policy. One possible conclusion is that it may be necessary for the government to create the conditions that would stimulate the arrival of <abbrev xlink:title="global value chains" id="ABBRID0EHEAC">GVCs</abbrev> to the national economy.</p>
      <p>Reorganization of <abbrev xlink:title="global value chains" id="ABBRID0ENEAC">GVCs</abbrev> by international companies in response to the consequences of the COVID-19 crisis is becoming particularly relevant today. <xref ref-type="bibr" rid="B12">Miroudot (2020)</xref> points out that the slowdown in the activity of production fragmentation in East Asia has been going on since 2011 firstly because of the change in the structure of demand for finished products in China: its manufacturing industry increasingly relies on local suppliers of components. The second reason is the digital transformation of business leading to the emergence of new business models that require that production be located closer to the consumer. The author notes that the pandemic reinforced this trend since the governments of many developing countries introduced incentives to localize production of components in their countries and raised tariffs on the import of raw materials. Along with rising freight rates and disruptions in transport logistics it will intensify re-shoring in East Asia. <xref ref-type="bibr" rid="B9">Kimura et al. (2020)</xref>, based on the example of the Asia-Pacific region, show that, in order to maintain macroeconomic and financial stability in developing countries during the COVID-19 pandemic, it was necessary to provide regional coordination of trade and investment policies aimed at ensuring flexibility of global supply chains of essential medical goods and services.</p>

The period of 1999-2018 was chosen for the following reasons: first, at the end of the 1990s and in the earlier 2000s, production within <abbrev xlink:title="global value chains" id="ABBRID0EEFAC">GVCs</abbrev> was growing rapidly, thanks to high world prices of natural resources that reached their historical peaks and to the growth rates of international trade that exceeded those of the world GDP (international trade continued to grow at this pace till the early 2010’s).</p>
      <p>The second reason is purely statistical: the data on many indicators prior to 1999 are unavailable as are the data on foreign value added after 2018, which makes it impossible for this study to assess the impact of the COVID-19 pandemic. The remaining approximately 50 developing countries were not included in the sample also because of the lack of necessary data or the presence of «outliers» (which, as a rule, significantly distort the model estimates unless they are deleted from a sample beforehand). The complete dataset used is presented in Annex I.</p>
      <p>The choice of the independent variables was based on the preliminary analysis of the existing research on the topic. All variables characterize the quality of business environment and have either macroeconomic or institutional nature. Moreover, as will be shown below, understanding the influence of these variables on developing countries’ integration into <abbrev xlink:title="global value chains" id="ABBRID0ELFAC">GVCs</abbrev> will allow us to draw important conclusions about the role of public policies in promoting effective participation in the international fragmentation of production. Since there are significant differences in the character of the economies included in the sample, the study makes use of a panel analysis.</p>
      <p>To determine the nature and extent of the impact of the chosen economic factors on the participation of developing countries in global supply chains, the following econometric model is applied:</p>
      <p><inline-graphic xlink:href="brics-econ-04-225-i001.jpg" xlink:type="simple" id="oo_871298.jpg"/> 		(1)</p>
      <p>Where α<sub>0</sub> is a constant; α<sub>1</sub>,α<sub>2</sub>,α<sub>3</sub>,α<sub>4</sub>,α<sub>5</sub> – estimated coefficients for explanatory variables; µ corresponds for unobservable heterogeneity between developing countries; ε is an error term. Indices <italic>i</italic> and <italic>t</italic> denote the number of the country and year, respectively (<italic>i</italic> = 1, …, 84; <italic>t</italic> = 1, …, 20).</p>
      <p>The dependent variable is the rate of upward participation in <abbrev xlink:title="global value chains" id="ABBRID0EJGAC">GVCs</abbrev>, i.e. foreign value added embodied in the country’s exports (FVA). The variable GDP_PERCAP is country’s per capita income that also indicates the volume and, implicitly, the structure of internal demand. The higher the GDP_PERCAP, the greater the demand for technologically sophisticated goods and services of high quality, and the lower the demand for processed raw materials; this stimulates exports of processed products used to produce final goods outside the country. The variable MAN denotes added value created in manufacturing industry – this indicator can be used as a proxy for the structure of national economy and its potential to host sophisticated production. The larger it is, the higher the degree of a country’s participation in complex products manufacturing. The volume of outward <abbrev xlink:title="foreign direct investment" id="ABBRID0ENGAC">FDI</abbrev> relative to GDP is represented by the variable FDI_OUT. It could be assumed that with the growth of outward <abbrev xlink:title="foreign direct investment" id="ABBRID0ERGAC">FDI</abbrev>, vertical integration intensifies, and the country’s participation in <abbrev xlink:title="global value chains" id="ABBRID0EVGAC">GVCs</abbrev> as a buyer of intermediate products expands, which means that the more open developing countries (TRADE_OPEN) are more attractive for the placement of production facilities by <abbrev xlink:title="transnational corporations" id="ABBRID0EZGAC">TNCs</abbrev>. As time required to organize business in the country (TIME_BUS) increases, the costs of foreign investment rise, impeding the country’s integration into <abbrev xlink:title="global value chains" id="ABBRID0E4GAC">GVCs</abbrev>. Moreover, the last variable can be seen as a proxy for the general quality of national institutions. The variables FVA, GDP_PERCAP, MAN and TRADE_OPEN are used with natural logarithm for a more correct specification of the model. The description of all the variables can be seen in Table <xref ref-type="table" rid="T1">1</xref>.</p>

      <p>Scatter plots of the dependent variable and chosen regressors are presented in Appendix <xref ref-type="fig" rid="F1">A1</xref>. The straight lines indicate the regression lines of the different pairwise regressions. We can conclude from their analysis that the discovered patterns are consistent with the theoretical provisions. The spread of observed values is generally uneven, which makes it necessary to use robust standard errors when estimating the model.</p>
      <p>Annexes A2 and A3 contain the main descriptive statistics and the correlation matrix of model variables, respectively. For example, the net outflow of <abbrev xlink:title="foreign direct investment" id="ABBRID0EBMAC">FDI</abbrev> from developing countries in 1999-2018 averaged 1.07% of GDP, and it took about 38 days to go through all the stages necessary to open a business. This is dramatically different from the OECD member countries, for which the average values of the corresponding indicators for the same period were 3.23% and 22 days, respectively, highlighting the importance of these factors for accelerating the integration of developing countries into <abbrev xlink:title="global value chains" id="ABBRID0EFMAC">GVCs</abbrev> (WDI, 2023). At the same time, the correlation of explanatory variables with each other is low, except for the correlation of ln(MAN) and ln(TRADE_OPEN) with ln(GDP_PERCAP) and the correlation of ln(TRADE_OPEN) with FDI_OUT. However, this is not expected to strongly skew the coefficient estimates, since the variables ln(GDP_PERCAP), ln(MAN) and FDI_OUT are highly correlated with the dependent variable (correlation coefficients of 0.59, 0.87 and 0.33, respectively). Therefore, no significant risk of multicollinearity is expected in the model under consideration.</p>
      <p>Further on econometric tests for stationarity and cointegration of the model variables were carried out since the use of non-stationary time series, as well as the lack of cointegration of selected variables, can lead to false results. After that, a direct evaluation of model (1) was made based on the available sample. In addition, the paper evaluated dynamic model (2) with three-period lags of explanatory variables.﻿</p>

      <p>The results of unit root tests for the variables included in the model can be seen in Table <xref ref-type="table" rid="T2">2</xref>. For appropriate testing, the two most common stationarity panel tests were used in the paper – LLC test and IPS test. The null hypothesis of both tests is that the series is non-stationary. The alternative hypothesis assumes that the series is stationary. The lag order of each of the variables was determined automatically by the Schwartz information criterion. The obtained results allow to reject the null hypothesis for all variables except ln(GDP_PERCAP) and ln(MAN) at the 1% significance level. So, we should conclude that ln(FVA), FDI_OUT, ln(TRADE_OPEN) and TIME_BUS series are zero-order integrated (I(0)), while ln(GDP_PERCAP) and ln(MAN) series are first-order integrated (I(1)).</p>

      <p>As the next step, we checked for the presence of cointegration of variables using the Johansen test. There are two main varieties of it: the trace test and the maximum eigenvalue test (max-eigen test). The null hypothesis in both tests is that the number of cointegrating equations is less than “r”. The alternative hypothesis is that it is not less than “r” (trace test) or equals “r+1” (max-eigen test). The test was conducted without a constant and a trend.</p>
      <p>According to the test results, the null hypothesis is rejected for all values of “r” from zero to five (see Table <xref ref-type="table" rid="T3">3</xref>). We conclude that at least five cointegration equations are significant at the 1% level. Therefore, estimates of model (1) for the levels of the variables will be super consistent.</p>

        <p>In this Section the results of model evaluation are presented and analyzed. First, we evaluate the basic model using various methods: pooled least squares, weighted least squares, fixed effects and random effects. In case of weighted least squares, the weights are based on the estimates of the error term variance for each country in the sample over the respective period.

        <p>It can be seen that the estimates of the coefficients for the explanatory variables are highly significant, and their signs correspond to the expectations stated in the previous Section. At the same time, the p-values of the Breusch-Pagan test and the Hausman test are equal to zero, which makes it possible to reject the hypothesis of validity of the generalized least squares estimates at any level of significance, as well as the hypothesis of the constancy of the error term variance for all observations of the sample. Hence, it is necessary to pick the fixed-effects model because it has the highest predictive quality. This choice is also consistent with logical considerations: the existing differences between developing countries are substantial and they should be determined by fundamental socio-economic factors rather than regarded as manifestation of pure chance.</p>
        <p>The obtained results show that the factors included in the model can explain 98% of the dispersion of foreign value added in developing countries’ exports for the period of 1999-2018.</p>
        <p>The estimation of the fixed effects model provides further insights into the impact of the selected economic factors on the nature and extent of developing countries’ participation in <abbrev xlink:title="global value chains" id="ABBRID0ERRAE">GVCs</abbrev>. Firstly, as their industrial potential is growing they become more and more integrated into complex and capital-intensive stages of <abbrev xlink:title="global value chains" id="ABBRID0EVRAE">GVCs</abbrev>: 1% increase in manufacturing value added in developing countries causes the corresponding growth of foreign value added in their exports by about 0.7%. Secondly, the obtained estimates reveal that the more outward foreign direct investment they make, the deeper they are integrated into <abbrev xlink:title="global value chains" id="ABBRID0EZRAE">GVCs</abbrev>, since <abbrev xlink:title="foreign direct investment" id="ABBRID0E4RAE">FDI</abbrev> is partly channeled to the construction or acquisition of production facilities abroad. Besides, reduction of tariff and non-tariff barriers to trade stimulates the expansion of developing countries’ participation in <abbrev xlink:title="global value chains" id="ABBRID0EBSAE">GVCs</abbrev>: 1% growth in the openness of their economies increases foreign value added in their exports on average by 0.83%. Finally, the saturation of the domestic market with necessary goods makes it expedient to obtain economic benefits through the development of assembly production and processing of intermediate products for export (the estimated elasticity of foreign value added in the developing countries’ exports by their real per capita income is about 1.21). The latter is vital for the economies heavily dependent on the world prices for raw materials. It is also important to note that simplification of procedure for starting a business and reduction of its administrative burdens could allow developing countries to attract significant foreign direct investment, which in turn would stimulate further integration into global production networks.</p>
        <p>The empirical distribution of the fixed effects is presented in Appendix <xref ref-type="fig" rid="F2">A4</xref>. As shown in the diagram, estimates of the fixed effects calculated based on the compiled data set vary from -4.5 to 3.2. However, for more than 50 countries out of total 84, their absolute values are within 1. Such a significant unevenness in the empirical distribution of fixed effects once again highlights the depth of differences in the degree of involvement of various developing countries in the processes of global accumulation of value.</p>

        <p>The obtained estimates confirm that all factors considered have significant impact on the amount of foreign value added in developing countries’ exports in the short run. However, some of them also determine the scope of participation of these countries in <abbrev xlink:title="global value chains" id="ABBRID0EMZAE">GVCs</abbrev> in the longer term. In particular, with a 1% increase in real GDP per capita, foreign value added in developing countries’ exports grows by an average of 1.1% in the short run and by 0.5% in the medium run. Furthermore, a rise in the share of net <abbrev xlink:title="foreign direct investment" id="ABBRID0EQZAE">FDI</abbrev> outflow in the GDP of developing countries by 1 p.p. leads to a short run increase in foreign value added in their exports by an average of 1.2% and a medium run growth of 0.6-0.7%. This empirical pattern seems logical, since foreign direct investment typically results in the building of long-term production and trade relations between enterprises involved. Besides, trade liberalization stimulates the expansion of developing countries’ participation in <abbrev xlink:title="global value chains" id="ABBRID0EUZAE">GVCs</abbrev> in a dynamic way. The short run effect of the rise in the openness of the economy by 1% for upward participation in <abbrev xlink:title="global value chains" id="ABBRID0EYZAE">GVCs</abbrev> is almost 0.48%, and the medium run effect is 0.35%. In other words, the fewer restrictions on foreign trade are imposed, the more secure is the country’s position in the global supply chain’s segments with high domestic value added.</p>

      <title>Conclusion</title>
      <p>The study has shown that developing countries have significant potential to increase their participation in <abbrev xlink:title="global value chains" id="ABBRID0EC1AE">GVCs</abbrev> and move up to more capital-intensive and high-tech stages of the production chain. Despite the varying nature of the current integration of developing countries into <abbrev xlink:title="global value chains" id="ABBRID0EG1AE">GVCs</abbrev>, empirical testing has revealed some common patterns. Richer economies with more developed manufacturing industries are more involved in the processing of raw materials and assembly of finished products. China, India and the newly industrialized countries of the “first wave”, which are heavily engaged in the production of machinery and equipment within the <abbrev xlink:title="global value chains" id="ABBRID0EK1AE">GVCs</abbrev>, provide conclusive evidence. South Africa, however, despite some success in assembling cars for the world’s leading automakers, has a low level of complexity and diversification of the manufacturing sector, which is the main reason for the country’s lower integration in the ascending segments of <abbrev xlink:title="global value chains" id="ABBRID0EO1AE">GVCs</abbrev>. It has become clear that the developing countries that consistently adhere to free trade policy are much more attractive for offshoring as part of the international fragmentation of production. Another important finding of the study is the conclusion about the role of the administrative burden on business as a factor which hinders effective integration of developing countries into <abbrev xlink:title="global value chains" id="ABBRID0ES1AE">GVCs</abbrev>. While the influence of market factors and trade policy has been investigated in the previous studies, the evaluation of the impact of administrative burden on the degree of these countries’ participation in global production networks is a major contribution of this paper to the understanding of the actual and potential place of developing economies in the global value chains.</p>
      <p>The analysis revealed the favorable dynamic effect of the volume of outward <abbrev xlink:title="foreign direct investment" id="ABBRID0EY1AE">FDI</abbrev> and the degree of openness of the economy on the participation of developing countries in <abbrev xlink:title="global value chains" id="ABBRID0E31AE">GVCs</abbrev>. Brazil, being one of the world’s largest producers of biofuels, is a good example, since Brazilian oil and gas <abbrev xlink:title="transnational corporations" id="ABBRID0EA2AE">TNCs</abbrev> (such as Petrobras) own numerous oil production and refining plants in Africa and Latin America. Petroleum products are then imported in Brazil at low tariffs on the production and sale of biofuels both on the domestic market and abroad. The host governments are to ensure the coherence of foreign trade and investment policies in the long run so that the development of trade relations with other countries and the resulting economies of scale could help modernize and diversify production in the <abbrev xlink:title="foreign direct investment" id="ABBRID0EE2AE">FDI</abbrev> recipient developing countries. State support for domestic small and medium-sized firms involved in the production of manufactured goods in the form of subsidies, tax breaks, loan guarantees, and assistance in finding overseas business partners can also allow developing countries to join <abbrev xlink:title="global value chains" id="ABBRID0EI2AE">GVCs</abbrev> more actively and with greater economic benefits. Measures are needed to simplify the procedure of registering businesses by foreign <abbrev xlink:title="transnational corporations" id="ABBRID0EM2AE">TNCs</abbrev>, improve transport and logistics infrastructure, enhance the transparency of the investment environment, strengthen political legitimacy and fight corruption. This paper does not examine the effects of a wide range of institutional factors on countries’ participation in <abbrev xlink:title="global value chains" id="ABBRID0EQ2AE">GVCs</abbrev>; this is a subject for further research.</p>
      <p>In modern conditions, global supply chains are undergoing significant changes due to both corporate decisions of the <abbrev xlink:title="transnational corporations" id="ABBRID0EW2AE">TNCs</abbrev> and transformation processes currently underway in the world economy. Post-2008 crisis trade tensions that have intensified practically to the degree of trade wars, a build-up of the global financial imbalances together with growing contradictions between advanced and developing countries have led to a slowdown in globalization processes in the world economy, forcing <abbrev xlink:title="global value chains" id="ABBRID0E12AE">GVCs</abbrev> to shrink and become more regional. The COVID-19 pandemic further affected <abbrev xlink:title="global value chains" id="ABBRID0E52AE">GVCs</abbrev>, especially in developing countries, causing cascading disruptions along production chains. The decline in the volume of foreign investment because of restrictive measures imposed on the cross-border capital movement resulted in substantial reduction of activity within <abbrev xlink:title="global value chains" id="ABBRID0EC3AE">GVCs</abbrev>. Obviously, developing countries suffered the greatest economic damage during the COVID-19 crisis, as for many of them <abbrev xlink:title="foreign direct investment" id="ABBRID0EG3AE">FDI</abbrev> and participation in <abbrev xlink:title="global value chains" id="ABBRID0EK3AE">GVCs</abbrev> are the major driving forces for economic growth and development.</p>
