Abstract

ABSTRACT The debate on the natural resource curse hypothesis has attracted the attention of policy makers and policy analysts for the past few decades. However, the empirical findings on such a hypothesis have proven inconclusive. Our study investigates the threshold effects of natural resource dependence on economic growth in sub-Sahara Africa (SSA) using both aggregate and disaggregate data from 1990 to 2019 by employing a threshold effect model. The results indicate a double threshold effect of natural resource rent on economic growth. In particular, below 6% of GDP, aggregate natural resource rent exerts a significant negative effect on economic growth. However, as the rents increase above 6% to about 15% of GDP its negative effect on economic growth significantly reduces. In addition, beyond 15% of GDP natural resource rent exhibit a substantial significant positive impact on economic growth. Further, the disaggregated data reveal that forest rents exhibit a strong weighty adverse effect on economic growth at all levels of thresholds. The study recommends that governments within the sub-region need to put in policies to ensure that natural resources generate at least 15% of GDP annually to promote growth.

SSA的自然资源依赖与经济增长：是否存在阈值效应？

在过去的几十年里，关于自然资源诅咒假说的争论引起了政策制定者和政策分析师的关注。然而，对这一假设的实证研究结果已被证明是不确定的。本研究采用阈值效应模型，利用1990年至2019年的汇总和分类数据，研究了撒哈拉以南非洲地区自然资源依赖对经济增长的阈值效应。结果表明，自然资源租金对经济增长具有双重门槛效应。特别是当自然资源总租金低于GDP的6%时，对经济增长产生显著的负面影响。然而，当租金上升到GDP的6%以上至15%左右时，其对经济增长的负面影响显著减弱。此外，超过GDP 15%的自然资源租金对经济增长有显著的积极影响。此外，分类数据显示，在所有阈值水平上，森林租金对经济增长都有严重的不利影响。该研究建议，该次区域各国政府需要制定政策，确保自然资源每年至少产生GDP的15%，以促进经济增长。

期刊介绍： Development Studies Research ( DSR) is a Routledge journal dedicated to furthering debates in development studies. The journal provides a valuable platform for academics and practitioners to present their research on development issues to as broad an audience as possible. All DSR papers are published Open Access. This ensures that anyone, anywhere can engage with the valuable work being carried out by the myriad of academics and practitioners engaged in development research. The readership of DSR demonstrates that our goal of reaching as broad an audience as possible is being achieved. Papers are accessed by over 140 countries, some reaching over 9,000 downloads. The importance of the journal to impact is thus critical and the significance of OA to development researchers, exponential. Since its 2014 launch, the journal has examined numerous development issues from across the globe, including indigenous struggles, aid effectiveness, small-scale farming for poverty reduction, sustainable entrepreneurship, agricultural development, climate risk and the ‘resource curse’. Every paper published in DSR is an emblem of scientific rigour, having been reviewed first by members of an esteemed Editorial Board, and then by expert academics in a rigorous review process. Every paper, from the one examining a post-Millennium Development Goals environment by one of its architects (see Vandermortele 2014), to ones using established academic theory to understand development-imposed change (see Heeks and Stanforth 2015), and the more policy-oriented papers that contribute valuable recommendations to policy-makers and practitioners (see DSR Editor’s Choice: Policy), reaches a multidisciplinary audience.
