摘要
本文基于2005—2020年中国285个地级市面板数据,采用多期DID模型评估环境信息披露政策对绿色创新能力的影响,实证检验了环境信息披露对绿色创新能力提升作用的区域、规模和主导产业异质性。研究表明:环境信息披露对提升绿色创新能力具有显著的提升作用,结果通过一系列稳健性检验;环境信息披露政策对东部、中部和东北部地区城市绿色创新能力的提升作用明显,但并未促进西部城市绿色创新能力的提升;环境信息披露的绿色创新能力驱动效应存在规模异质性,提升效应大小依次为中等城市、小城市和大城市;环境信息披露对资源型城市绿色创新能力的提升作用大于非资源型城市。基于上述结论,从信息披露政策和提升城市绿色创新能力等方面对中国实现2060年碳中和目标提出三点建议。
Based on the panel data of 285 prefecture-level cities in China from 2005 to 2020,a time-varying DID model is used to evaluate the impact of environmental information disclosure on green innovation capability,and to empirically test the regional,scale and leading-industry differences in the promotion of green innovation capability by environmental information disclosure.The research shows that environmental information disclosure has a significant effect in improving green innovation capabilities,and the results have passed a series of robustness tests.Environmental information disclosure policies have significantly improved the green innovation capability of cities in the eastern,central and northeastern regions of China,but have not promoted that of the western region.The driving effect of environmental information disclosure on green innovation capabilities is heterogeneous in scale,and the order by promotion effect is:medium cities>small cities>large cities.Environmental information disclosure enhances the green innovation capabilities of resource-based cities more than non-resource-based cities.Based on the above conclusions,three suggestions are made for China to achieve the carbon neutral goal by 2060.
