数字经济促进碳减排的效应与机制分析——以湖北省为例

Analysis of the Effect and Mechanism of Digital Economy in Promoting Carbon Emission Reduction:A Case Study of Hubei Province

运用2011—2021年湖北省地级市的城市数据研究数字经济促进碳减排的效应与机制。研究发现湖北省数字经济发展能够显著推进碳减排,数字技术创新和能源利用效率提升发挥了重要的中介作用。同时异质性分析表明,受到湖北省城市群发展差异以及资源禀赋差异的影响,数字经济发展对于武汉城市圈以及资源型城市的碳减排效应更为突出。因此湖北省应深入发展数字经济,因地制宜制定发展战略,以数字技术创新和能源利用效率提升助力区域碳减排。

Using the data of prefecture-level cities in Hubei Province from 2011 to 2021,this paper studies the effect and mechanism of digital economy in promoting carbon emission reduction.The study finds that Hubei digital economy can significantly promote carbon emission reduction.Digital technology innovation and energy efficiency improvement play an important mediating role.Furthermore,because of the difference in the urban agglomerations and resource endowments,digital economy has a more prominent effect on the carbon emission reduction of Wuhan urban agglomeration and resource-based cities.Therefore,it is necessary for Hubei Province to develop the digital economy,formulate development strategies according to local conditions,and reduce regional carbon emissions with digital technology innovation and energy efficiency improvement.
