高水平开放自贸区政策是否提升了城市绿色创新效率
Has the policy of high-level opening-up free trade zones improved the urban green innovation efficiency?
摘要
Abstract
This paper used balanced panel data from 276 prefecture level cities in China from 2009 to 2022,and took the imple-mentation of the policy of high-level opening-up free trade zones as a quasi-natural experiment.Using the multi-period DID meth-od and spatial Durbin model,this paper explored the impact,mechanism,and spatial spillover effects of the policy of high-level open-ing-up free trade zones on the urban green innovation efficiency.The results indicated that:①The policy of high-level opening-up free trade zones in China has significantly improved the urban green innovation efficiency through scale and structural effects,which was conducive to high-quality and sustainable urban development.②Coastal cities benefited more from the green innovation efficiency im-provement of the policy of free trade zones compared to inland cities.And the higher the city level was,the better it could seize develop-ment opportunities from the high-level opening-up practices represented by the establishment of free trade zones,finally improving the green innovation efficiency of cities effectively.③In terms of spatial innovation spillover effects,the policy of high-level opening-up free trade zones has had a positive direct and indirect impact on the urban green innovation efficiency,and there was also a positive spatial spillover effect.关键词
