Sub-Saharan Africa (SSA) has abundant natural resources and attracts substantial investment, especially from China, but sustainable growth remains limited. This study examines the persistent disconnect between resource wealth, foreign financing, and long-term economic performance in the region. Using 20 years of panel data from 31 SSA countries, we estimate seven econometric models — including fixed effects, dynamic panels, and instrumental variables (IV) — to assess the long-run impact of natural resource rents, Chinese investment, trade flows and foreign direct investment (FDI) on GDP growth.
Exports are consistently associated with stronger economic growth. By contrast, Chinese investment does not show a robust effect across specifications. Natural resource rents have a weak or no correlation with growth, but become significant in the IV model, suggesting that their impact is mediated by institutional quality. Imports are negatively or insignificantly associated with growth until endogeneity is addressed, after which their effect turns positive indicating the importance of trade efficiency. FDI consistently correlates with lower growth, pointing to problems such as capital flight or extractive investment practices.
This study challenges the assumption that Chinese finance and resource abundance are driving development in SSA. The findings highlight the critical role of effective governance, transparent resource management, and coherent trade and investment policies. Policymakers need to align external finance and natural resource use with institutional reforms to promote sustainable growth.
Chinese Financing, Natural Resource Rents, Panel Data Analysis, Sustainable Economic Growth, sub-Saharan Africa
The interplay between Chinese financing and natural resource rents in Africa has important implications for the continent’s long-term economic development (
Africa, with its vast natural resources accounting for approximately 30% of the world’s mineral reserves, 8% of global natural gas, and 12% of global oil reserves occupies a strategic position in the global economy. The continent also holds the world’s largest deposits of critical minerals such as cobalt, diamonds, platinum, and uranium, along with significant reserves of gold, chromium, and platinum (United Nations Environment Programme [

Globally, natural resource rents as a percentage of GDP are much lower, indicating less dependence on natural resources worldwide. The data show global peaks in 1979 (5.8%) and 2011 (4.8%), but most of the time the global average remains under 6% throughout the period. Particularly from 2015 to 2020, the global resource rents were consistently declining to between 1.5% and 2.5% of GDP. This suggests that while resource extraction has an impact on the global economy, it is not as significant as it is in SSA.
The stark contrast between the rents in SSA and their global average highlights the region’s vulnerability to the “resource curse,” where a country’s heavy reliance on natural resources can hinder economic stability and sustainable growth. Sub-Saharan Africa’s resource rents fluctuate sharply, often mirroring global price trends but with a more pronounced impact on the region’s economy. This heavy dependency makes the region particularly susceptible to shifts in global commodity prices, which directly affect its GDP and economic stability.
Chinese investment has provided critical capital for development and infrastructure improvements in sub-Saharan Africa, but it also raises concerns about debt sustainability, environmental degradation, and equitable distribution of economic benefits (
Despite the substantial influx of Chinese financing into sub-Saharan Africa’s resource-rich economies, a critical gap remains in understanding the long-term sustainability and broader implications of this financial relationship for the region’s economic development. While the Chinese capital has undoubtedly accelerated infrastructure development and sectoral growth, reliance on natural resources as collateral may exacerbate the “resource curse”: market volatility, governance challenges, and overdependence on a single sector can hinder economic growth. (
The primary objective of this study is to explore the complex interplay between Chinese financing and natural resource rents in sub-Saharan Africa, and how this relationship influences economic sustainability, governance, and institutional effectiveness (based on the hypotheses in Table
| Hypothesis | Explanation |
|---|---|
| Resource Curse Hypothesis | Suggests that economies heavily dependent on natural resource wealth may experience slower growth due to poor governance, misallocation of resources, and economic volatility ( |
| Chinese Investment and Growth Hypothesis | Examines whether Chinese financing contributes to economic growth. Chinese investments provide infrastructure and capital but their effectiveness depends on governance, sector allocation, and the nature of the projects ( |
| Governance-Dependent Resource Utilization Hypothesis | Argues that the developmental benefits of natural resource wealth are not automatic but depend on the quality of governance. Effective institutions and transparent policies determine whether resource endowments lead to sustainable growth or exacerbate inefficiencies and inequality ( |
| Trade-Led Growth Hypothesis | Proposes that exports are a key driver of economic expansion. Countries that focus on export-oriented strategies tend to have higher productivity, foreign exchange earnings and industrialization ( |
| FDI Paradox Hypothesis | Challenges the conventional belief that FDI always stimulates growth. In certain contexts, especially in extractive industries, FDI may contribute to capital flight, weak domestic linkages, and economic instability instead of fostering long-term development ( |
This section provides an overview of the theoretical and empirical literature on the issues under consideration. It also identifies the research gap to be filled by the study.
The resource curse theory (RCT) suggests that economies rich in natural resources often experience slower growth owing to economic distortions, governance challenges, and susceptibility to commodity price volatility (
Unlike traditional Western loans, which normally come with strict governance and transparency conditions, Chinese financing is often structured as resource-backed loans, where African governments pledge future resource revenues as collateral (
This paper critically engages with RCT by analyzing the extent to which Chinese financing contributes to sustainable growth beyond the extractive sector. The findings challenge the conventional assumption that resource-backed lending automatically leads to economic expansion, showing instead that its impact is contingent on governance structures, fiscal policies and the ability of African states to negotiate favourable terms. The study thus refines the RCT by showing that external financing mechanisms can either exacerbate or mitigate resource-related economic challenges, depending on the conditions under which they are deployed.
The Dependency Theory (DT) posits that developing economies remain structurally dependent on wealthier nations owing to historical patterns of resource extraction and unequal trade relations (Prebisch, 1950; Frank, 1967). Traditionally, this framework has been applied to the North-South economic relations, where African countries export raw materials and import high-value manufactured goods, reinforcing the cycles of underdevelopment (
Chinese financing presents a paradox within the DT framework. On the one hand, China’s investments in infrastructure, energy and mining mirror historical patterns of extractive engagement, where African nations remain primary suppliers of raw materials with limited capacity for industrialization (Alden, 2017). This dynamic is in line with DT’s core argument that resource-rich but structurally weak economies remain dependent on external actors for capital and market access. On the other hand, unlike Western aid and loans, Chinese funding is often packaged with infrastructure development and technology transfer, which in theory could promote greater economic self-sufficiency (
This study extends DT by assessing whether Chinese financing represents a new form of dependency or a viable alternative development pathway. Empirical findings show that while the Chinese capital has facilitated infrastructure expansion, it has not significantly contributed to economic diversification. Continued reliance on resource-backed loans and the resulting trade imbalances suggest that African economies remain vulnerable to external financial pressures, raising concerns about long-term sovereignty over resource wealth. The study also identifies cases where Chinese investments have supported industrialization, albeit to a limited extent.
By critically re-examining the DT through the lens of Chinese financing, this paper provides a deeper perspective on Africa’s economic positioning in the global economy. It highlights the need for African governments to renegotiate the terms of Chinese engagement, ensuring that investments are aligned with long-term developmental goals rather than reinforcing patterns of external dependence.
Both the RCT and DT offer new insights into Africa’s economic challenges, but neither fully captures the complexities created by Chinese financing. This study contributes to the theoretical discourse by demonstrating that external financing, particularly from China, can either reinforce or challenge traditional dependency structures and resource-related economic constraints, depending on governance quality, investment allocation, and policy frameworks. The findings underscore the need for African economies to use external capital strategically to ensure that foreign investments drive diversification and long-term economic resilience rather than perpetuating dependence on extractive industries.
The link between natural resource rents, Chinese financing, and sustainable economic growth in sub-Saharan Africa has received increasing scholarly attention because of China’s growing role in the region. This relationship is central to understanding the broader implications of China’s economic engagement and its potential influence on the long-term development prospects of the sub-Saharan African countries, particularly those rich in natural resources. China’s involvement in large-scale infrastructure projects, often financed by loans backed by natural resource contracts, has caused both optimism and concern about the prospects for economic diversification, governance, and long-term sustainability.

The role of governance and institutional quality in mediating the impact of natural resource rents and Chinese financing on economic growth has been the focus of recent empirical studies.
A more recent study by
The empirical literature on the nexus between natural resource rents, Chinese financing, and sustainable economic growth in Sub-Saharan Africa presents a nuanced picture. Most authors agree that the Chinese money has played a crucial role in coping with infrastructure deficits and stimulating economic growth in the region, although the sustainability of this growth remains uncertain. The literature consistently highlights that governance quality, institutional strength, and economic diversification largely determine whether Chinese financing contributes to sustainable, long-term development or reinforces patterns of dependency and vulnerability to global commodity price fluctuations.
In the previous research on the linkages between natural resource rents, Chinese financing, and sustainable economic growth in Sub-Saharan Africa, significant gaps remain in understanding their long-term implications for the region’s development. Much of the existing literature focuses on the short-term impacts, such as infrastructure development and immediate growth driven by the Chinese financing. However, the broader consequences for sustainable development, economic diversification, institutional quality and governance are underexplored. In particular, there is little empirical research on how Chinese financing secured through resource rents influences the structural transformation of economies, especially beyond the extractive sectors, and on its long-term effects on economic diversification. Studies examining the role of governance and institutional quality often consider these factors in isolation, overlooking the interplay between governance, Chinese loans and resource rents and its impact on long-term sustainability. Another gap is in the research that links Chinese financing to the risks of the “resource curse” and economic dependency. Much of the literature treats these phenomena separately, but their intersection could exacerbate Africa’s vulnerability to global commodity price fluctuations and debt crises. The environmental and social impacts of Chinese investment, particularly on local communities and sustainability of resource extraction, have not been sufficiently addressed. To bridge these gaps and design strategies for the appropriate use of resource wealth and external finance, it is necessary to carry out comprehensive research into the relationships between the factors that can impede or promote sustainable economic development in Sub-Saharan Africa.
This study employs a panel data methodology to investigate the influence of various factors, namely Chinese financing, natural resource rents, imports, FDI, and exports, on the growth (GDP) of African countries. The analysis is carried out using several econometric models. This approach enables a nuanced examination of the relationships between the variables and their joint impact on economic performance across the region. The research is based on 20 years of panel data, covering a comprehensive range of economic indicators from a number of reputable sources. The dataset, drawn primarily from the World Bank’s Development Indicators, provides consistent and comprehensive information on the key variables, such as GDP, economic growth, trade flows and natural resource rents, ensuring a reliable basis for analysis.
This section introduces econometric models used in the analysis. The key variables are defined as follows: GDPit: GDP of country i at time t, Chinese Financingit Chinese financing of country i at time t, Natural Rentsit: Natural resource rents of country i at time t, Importsit: Imports of country i at time t, FDIit: FDI of country i at time t, Exportsit: Exports of country i at time t, Inflationit: Inflation values for country i at time t.
ln (GDPit) = β0 + β0ln (Chinese Financingit) + β2ln (Natural Rentsit) +
β3ln (Importsit) + β4ln (FDIit) + β5ln (Exportsit) + μi + εit (1)
Equation (2) examines how natural resource rents moderate the relationship between Chinese financing and GDP by including an interaction term:
ln (GDPit) = β0 + β1ln (Chinese Financingit) + β2ln (Natural Rentsit) +
+ β3ln (Chinese Financingit × Natural Rentsit) + β4ln (Importsit) + β5ln (FDIit) +
+ β6ln (Exportsit) + μi + εit (2)
Equation (3) incorporates inflation to control for other influences on GDP:
ln (GDPit) = β0 + β1ln (Chinese Financingit) + β2ln (Natural Rentsit) +
+ β3ln (Importsit) + β4ln (FDIit) + β5ln (Exportsit) + β6ln (Inflationit) + μi + εit (3)
Equation (4) includes lagged GDP to account for economic persistence:
ln (GDPit) = β0 + β1ln (GDPit – 1) + β2ln (Chinese Financingit) + β3ln (Natural Rentsit) +
+ β4ln (Chinese Financingit × Natural Rentsit) + β5ln (Importsit) + β6ln (FDIit) +
+ β7ln (Exportsit) + μi + εit (4)
Equation (5) controls for time-invariant country-specific characteristics.
ln (GDPit) = β1ln (Chinese Financingit) + β2ln (Natural Rentsit) + β3ln (Importsit) +
+ β4ln (FDIit) + β5ln (Exportsit) + β6In (Inflationit) + αi + γt + εit (5)
Equation (6) assumes that country-specific effects are random and uncorrelated with the independent variables:
ln (GDPit) = β1ln (Chinese Financingit) + β2ln (Natural Rentsit) + β3ln (Importsit) +
+ β4ln (FDIit) + β5ln (Exportsit) + β6In (Inflationit) + μi + γt + εit (6)
If Chinese Financingit is endogenous, an instrumental variable (Z_it) is needed. The two-stage least squares (2SLS) estimation is as follows:
First Stage:
ln (Chinese Financingit) = β0 + β1Zit + β2ln (Natural Rentsit) + β3ln (Importsit) +
+ β4ln (FDIit) + β5ln (Exportsit) + β6In (Inflationit) + αi + γt + vit (7)
Second Stage:
ln(GDPit) = β1ŷ_ln (Chinese Financingit) + β2ln (Natural Rentsit) + β3ln (Importsit) +
β4ln (FDIit) + β5ln (Exportsit) + β6Inflationit + αi + γt + εit (8)
where Zit is an instrument and ŷ_ln (Chinese Financingit) is the predicted value from the first stage.
This section shows how Chinese financing and natural resource rents influence sustainable economic growth in SSA. The results are obtained from several econometric models, using two decades of panel data.

The results of this study provide critical insights into the complex interactions between natural resource wealth, foreign investment, trade dynamics, and economic growth in Sub-Saharan Africa (SSA). By employing multiple econometric models, including an instrumental variable (IV) approach, the study uncovers nuanced relationships that challenge conventional assumptions about economic development in resource-rich economies. The results largely confirm the importance of governance quality in determining the effectiveness of natural resource rents, while also highlighting the limited direct impact of Chinese financing on economic growth. This section discusses the resource curse hypotheses.
The resource curse hypothesis suggests that natural resource rents do not contribute to economic growth but may impede it in case of inefficient governance. This study evaluates the hypothesis by analyzing the relationship between natural resource rents and GDP growth; it uses several econometric models and emphasizes the role of governance quality as a mediating factor. The findings mean that while resource rents have a weak or conditional correlation with economic growth, their effectiveness is significantly influenced by governance structures. These results support the resource curse theory, which posits that resource-rich economies often experience lower long-term growth because of rent-seeking behavior, weak institutions and economic mismanagement (
This hypothesis tests whether Chinese financial inflows materially contribute to economic growth in SSA. Employing multiple econometric specifications, the study has found that Chinese financing does not exhibit a statistically significant effect on GDP growth across all model variations. This result challenges conventional assumptions about the developmental benefits of Chinese investment in SSA. Consequently, the null hypothesis is rejected, indicating that Chinese investment does not inherently promote economic expansion in the region. These findings are consistent with recent studies suggesting that Chinese financing exerts a marginal, statistically insignificant impact on economic growth in Africa. For example,
This hypothesis asserts that the impact of natural resources on economic growth depends on governance quality. Using an instrumental variable (IV) approach, the study shows that resource rents can become significant determinants of economic performance only when governance quality is explicitly considered. This finding is consistent with existing research that emphasizes the role of strong institutions in mitigating the negative effects of resource dependence (
For instance,
This hypothesis proposes that exports have a positive influence on economic growth, while the effects of imports, initially negative, become positive once endogeneity is taken into account. The study provides robust empirical evidence supporting this proposition, demonstrating that exports consistently enhance GDP growth. Moreover, while imports are initially negligible or negative, they have a positive impact when endogeneity is given consideration. These findings support the classical trade theory and confirm that well-structured trade policies make a significant contribution to economic performance.
Therefore, the null hypothesis is not rejected. The study’s findings are consistent with research that highlights export diversification as a crucial driver of African economic growth (
Mainstream economic theories suggest that FDI should positively contribute to economic growth by bringing in capital, technology, and managerial expertise (
This article empirically evaluates the key drivers of economic growth in SSA, focusing on natural resource rents, FDI, trade, and Chinese financing. We find that resource wealth can support growth, but only when institutional governance is strong. Poor governance, characterized by opacity and rent-seeking, undermines the potential benefits of resource endowments, so policy reforms aimed at strengthening institutions and regulatory oversight are critical to translating resource rents into sustainable development outcomes.
FDI has generally had adverse effects in SSA, largely owing to capital flight, weak domestic linkages, and extractive investment strategies. To counter this, governments should implement policies enforcing local content requirements, mandating technology transfer, and aligning foreign investments with national industrial goals. Without such measures, FDI may entrench structural dependency rather than promote economic transformation.
Chinese financing yields mixed results. While it has facilitated infrastructure development, its economic impact remains limited outside extractive sectors. To ensure developmental relevance, financial arrangements should be restructured to promote local value addition, industrial linkages, and knowledge transfer. SSA governments must play a proactive role in aligning such financing with long-term growth priorities.
Trade consistently contributes to economic growth, particularly through export-oriented strategies and market diversification. Countries with competitive and diversified export portfolios tend to perform better. Accordingly, trade policy should promote product sophistication, logistical efficiency, and deeper integration into global value chains. Import structures must be reoriented to favour capital and intermediate goods over non-essential consumer imports.
The study highlights governance as a central condition for converting natural resource wealth and foreign capital into inclusive, sustainable growth. Strong institutions, coherent investment strategies and targeted trade policies are essential for mitigating structural vulnerabilities and supporting economic transformation.
A key limitation of this study is its reliance on the national-level aggregate data, which may obscure sector-specific or subnational dynamics. Future research should investigate the differential sectoral impacts of Chinese financing, the role of governance in shaping FDI outcomes, and the long-term effects of trade liberalization and regional integration. Disaggregated and longitudinal data should contribute to more precise policy guidance.
