The Impact Of Natural Resource Abundance On Green Economic Growth From The Perspective Of Institutional Quality

Green economic growth emphasizes the coordinated development of economy and environment,and regards the protection and rational utilization of natural resources as an important part of the economic system.The green transformation of Belt and road countries is crucial for the global green and low-carbon development.Belt and Road countries are rich in natural resources,and the advantages of natural resource endowments have affected the economic development mode in these countries,the large consumption of natural resources has also brought serious environmental problems.Therefore,facing the dual tasks of economic growth and green development,studying the impact of natural resource abundance on green economic growth and the role of institutional quality is of great significance for Belt and Road countries to achieve green growth.The main research contents of this thesis include: first,through the existing theories and literature,combining green development theory and institutional economic theory with the "resource curse" theory,a new perspective was provided for the analysis of the impact of natural resource abundance on green economic growth,and the role of institutional quality on the relationship and the transmission path were considered;Second,based on the data of 48 Belt and Road countries from 2007 to 2019,the SBM model and the Global Malmquist-Luenberger index were combined to measure and further analyze the green economic growth in Belt and Road countries.Third,the impact of natural resource abundance on green economic growth was empirically analyzed.And a mediated moderator model was constructed to examine the role of institutional quality in the relationship,and the transmission pathways of this role were further explored from industrial structure upgrading,green technology innovation,and human capital.Fourth,a panel threshold model was constructed to verify the difference in the impact of natural resource abundance on green economic growth under different institutional quality levels.Finally,based on the research conclusions,policy suggestions were put forward to promote the rational utilization of natural resources and achieve green economic growth in Belt and Road countries.The results showed that:(1)The overall green economic growth level of Belt and Road countries was between 0.4-2,and the difference in green development of countries with different income levels was obvious.(2)The richer the natural resources of Belt and Road countries,the less efficient the growth of green economy.Institutional quality could weaken the inhibitory effect of natural resource abundance through industrial structure upgrading and human capital.The heterogeneity results suggested that the natural resource curse on green economic growth occurred in low-and middle-income countries and the Middle East,while natural resources were welfare in Central and Eastern Europe.(3)When the institutional quality exceeded the threshold value,the inhibitory effect of natural resource abundance was transformed into a promotion effect.The results of heterogeneity showed that institutional quality was conducive to eliminating the natural resource curse on green economic growth in low-and middleincome countries,and was conducive to increasing the marginal contribution of natural resource abundance in high-income countries.Therefore,improving the institutional quality and giving play to their positive role in industrial structure upgrading and human capital is conducive to improving the efficiency of natural resources utilization and achieving green development in Belt and Road countries.
