摘要：The purpose of this study is to examine the impact of institutional quality on foreign direct investment (FDI) using panel data of 117 countries around the world from the period of 2001 to 2018. To enhance the accuracy of the estimation results, this study includes various statistical tests to select the estimation method that best fits the sampling data used in this study. Furthermore, while the robust standard error is applied to correct the problem of heteroscedasticity, this study addresses the potential endogeneity problem by system GMM estimation. The results indicate that the improvement in institutional quality significantly and positively contributes to FDI. More importantly, the results also reveal that economic integration has improved the role of institutional quality, indicating that the promotional effects of institutional quality on FDI are greater in economic integration areas. The results also suggest that the launch of China’s Belt and Road Initiative has greatly enhanced the promotional effects of institutional quality on FDI. The findings of this study offer policy implications for policymakers to take measures to improve institutional quality and thereby to enhance FDI and further accelerate the formation of economic integration in a more sustainable way.
