International Comparison on Determinants of Green Growth —Empirical Analysis on Panel Data of G20

A Green Growth Index(GGI) was constructed from the perspective of"greenization" by taking resource constraint and environmental performance into the account of traditional productivity index. The Epsilon-based measure, the global malmquist,the Zofio decomposition, and the K-W rank-sum techniques were utilized to observe the status, trends, and determinants of GGI of G20 countries during 2000-2010 to identify contributors and optimal paths to achieve green growth. Our findings revealed that:GGI stayed stable in G20 while increased and decreased in BRICS and other emerging markets; China's GGI was the lowest and was lower than the GGI of advanced countries and the average GGI of G20;among all the determinants,technological change and scale efficiency improved in the G20,and institutional optimization contributed greatly to the advanced economies,the BRICS,and China, but not the emerging markets. Scale bias of technology change only exerted positive effects on developed countries,while played negative effects on other groups. Drawing on the governance theory and the technological transition concept,this study suggested that China need to put forward a green technological transition and strength its green governance capacity to facilitate a fundamental change in the old economic growth pattern to become green.
