数字经济的节能减排效应及作用机制OACHSSCDCSTPCD

This paper puts the digital economy,energy intensity,and carbon emission intensity into a unified framework,constructs a spatial correlation network weight matrix of the digital economy,and uses the Spatial Dubin Model to test.It is found that the impact of the digital economy on energy intensity and carbon emission intensity presents an inverted"N"pattern,with sig-nificant spatial spillover effect.The development of the digital economy can achieve a win-win situation of"energy saving"and"emission reduction"at a certain stage.The test of the dual dimensions of digital industrialization and industrial digitization reveals that,digital industrialization affects carbon emission intensity by changing the degree of industrial agglomeration through the layout of digital industries among regions and their attractiveness to factors;industry digitization is embedded into various industries through digital technology,improving resource allocation efficiency and energy utilization efficiency,and influencing carbon emis-sion intensity through energy intensity.This provides policy inspiration for achieving the"dual carbon"goal through the develop-ment of the digital economy.
