“…Some authors (e.g., Ding and Field, 2005;Brunnschweiler and Bulte, 2008) have made a distinction between the concepts of "natural resource abundance" and "natural resource dependence", and provided empirical evidence that what really triggers the resource curse is the excessive dependence on natural resources or resource-based industries rather than the abundance in natural resources per se. While many studies have confirmed the resource-curse hypothesis, this negative effect may be mitigated or even turn out to be positive depending on several factors, including for example, the level of human capital accumulation and the institutional quality (e.g., Qiang and Jian, 2020;Zallé, 2019), whether there exist lower transports costs and encouragement of innovation (e.g., González-Vala and Pueyo, 2019), and if natural resource rents are used to promote export diversification, including through resource-based industrialization (e.g., Djimeu and Omgba, 2019;Massol and Banal-Estañol, 2014;Ross, 2019).…”
