自由贸易试验区对绿色创新效率的影响研究
Study on the Impact of Pilot Free Trade Zones on Green Innovation Efficiency
摘要
Abstract
This study explores the impact of the pilot free trade zone policy on green innovation efficiency by empoying the differ-ence-in-differences method using panel data from 284 cities in China from 2004 to 2021.The findings show that this policy significantly enhances the green innovation efficiency in the pilot regions,and multiple robustness tests verify the reliability of this conclusion.Mechanism analyses show that this policy improves green innovation efficiency in the pilot regions by promoting green technology inno-vation,enhancing industrial agglomeration and reducing resource dependence.In addition,the policy was found to be more effective in eastern,coastal and non-resource-based cities.关键词
