Research on the Carbon Emission Effect and Influencing Factors of Digital Economy Promoting Urban Green Development
本文基于2010～2021 年我国284 个地级市面板数据,采用超效率SBM模型等方法,研究数字经济对城市绿色发展的碳排放效率及其影响机制.研究结果显示,数字经济发展有助于提升城市的碳排放效率.其中,财政支出绩效和环境规制强度起到中介作用;数字经济在经济发展速度和人力资本水平的调节下,更显著地促进城市的碳排放效率;同时,数字经济对城市碳排放效率的影响存在明显的异质性.因此,本文提出了加强数字经济发展与碳排放效率协同增长、优化政府财政支出、加快数字城市建设等建议.
Based on the panel data of 284 prefecture-level cities in China from 2010 to 2021,this paper studies the carbon emission efficiency of digital economy on urban green development and its influencing mechanism by using the super-efficiency SBM model and other methods.The results show that the development of digital economy helps to improve the carbon emission efficiency of cities.Among them,fiscal expenditure performance and environmental regulation intensity play an intermediary role.Under the adjustment of the speed of economic development and the level of human capital,digital economy more significantly promotes the carbon emission efficiency of cities.At the same time,there is obvious heterogeneity in the impact of digital economy on urban car-bon emission efficiency.Therefore,this paper puts forward some suggestions,such as strengthening the coordinated growth of digi-tal economy development and carbon emission efficiency,optimizing government fiscal expenditure,and accelerating the construc-tion of digital cities.
