摘要
基于我国2006—2019年218个地级市的面板数据,实证分析智慧城市建设对碳排放强度影响的作用机理。研究发现:智慧城市建设能够显著抑制城市碳排放强度,且具有稳健性;智慧城市建设对不同地区碳排放强度的影响存在异质性;产业结构转型升级和技术创新能力提升是智慧城市建设降低碳排放强度的有效路径;政府环境规制强度能够有效促进智慧城市建设的碳减排效应。
Based on the panel data of 218 prefecture-level cities from 2006 to 2019 this paper empirically analyzes the mechanism of the impact of smart city construction on carbon emission intensity.It is found out that(1)smart city construction can significantly restrain urban carbon emission intensity and is robust;the influence on carbon emission intensity in different regions is heterogeneous;the transformation and upgrading of industrial structure and the improvement of technological innovation capacity are the effective ways to reduce carbon emission intensity in smart city construction;the intensity of government environmental regulation can effectively promote the carbon emission reduction effect of smart city construction.
