摘　　要：绿色创新对破解资源环境制约、提高碳生产率、推进生态文明建设具有重要作用。文章运用SFA-Malmquist方法评估我国279个地级市2003—2018年的碳生产率,构建面板门槛模型探讨财政分权差异下绿色创新对碳生产率的门槛特征。研究结果表明,绿色创新促进了我国地级市碳生产率的提高,财政分权对于绿色创新与碳生产率的关系则存在门槛效应,当处于阈值左侧时,随着财政分权程度的提高,绿色创新对碳生产率的促进作用降低;财政分权程度在东、中、西部地区存在差异,这种差异使得不同地区绿色创新对碳生产率的促进作用呈现异质性。Green innovation plays an important role in breaking resource and environmental constraints,improving carbon productivity,and promoting the construction of ecological civilization.This paper uses the SFA-Malmquist method to evaluate the carbon productivity of 279 prefecture-level cities in China from 2003 to 2018,and constructs a panel threshold model to explore the threshold characteristics of green innovation on carbon productivity under fiscal decentralization differences.The research results go as below:Green innovation promotes the improvement of carbon productivity in China’s prefecture-level cities,and fiscal decentralization has a threshold effect on the relationship between green innovation and carbon productivity.When it is on the left side of the threshold,with the increase of fiscal decentralization degree,the promoting effect of green innovation on carbon productivity decreases.The degree of fiscal decentralization is different in eastern,western and eastern regions,which results in the heterogeneity of promoting effect of green innovation on carbon productivity in different regions.
