摘　　要：基于2011—2021年中国282个城市面板数据,实证检验数字经济对碳排放强度的影响。研究发现,数字经济的发展能显著降低城市碳排放强度,并且存在先降后升的“U”形特征。以产业结构高级化的质、产业结构高级化的量、绿色技术创新作为调节变量,检验得出产业结构高级化的质强化了数字经济对碳排放强度的负向作用,而产业结构高级化的量和绿色技术创新则弱化了这种负向作用。Based on the panel data of 282cities in China from 2011—2021,the impact of digital economy on carbon emission intensity was empirically tested.It is found that the development of the digital economy can significantly reduce the intensity of urban carbon emissions,and there is a“U-shaped”characteristic of first decreasing and then increasing.Using the quality of industrial structure upgrading,the quantity of industrial structure upgrading,and green technology innovation as moderating variables,it is found that the quality of industrial structure upgrading strengthens the negative effect of digital economy on carbon emission intensity,while the quantity of industrial structure upgrading and green technology innovation weaken this negative effect.

关 键 词：数字经济 碳排放强度 调节效应
