中国数字经济网络发展与“绿色中国”建设 ———基于碳减排的证据

Research on the Mechanism of the Impact of Digital Economy Development on Spatial Carbon Emissions from the Perspective of Social Networks

摘要:

本文基于 2011—2021 年各省数字经济发展水平,运用社会网络分析构建省际数字经济网络,分析数字经济网络特征,探索数字经济发展水平和数字经济网络地位对空间碳排放的影响。研究发现:①中国数字经济网络发展迅速,广东、江苏、山东等东部省份处于网络中心地位,呈中心向周边地区再向边缘地区扩散的特点。②数字经济网络能显著影响碳排放,当地数字经济网络发展程度越高越有利于降低碳排放,而数字经济网络地位越低越不利于降低碳排放。③经济发展和能源强度是数字经济网络作用于碳排放的重要间接渠道。 相关政策制定需重视区域数字经济发展差异,通过信息共享、技术外溢和资源配置等措施,发挥数字经济网络效应,实现数字经济区域间的协调发展,有效促进碳减排

Abstract:

Based on the development level of digital economy in each province from 2011 to 2021, social network analysis was conducted to build an inter provincial digital economy network, the characteristics of digital economy network was analyzed, and the impact of digital economy development level and digital economy network status on spatial carbon emissions were further explored. Research finds that the digital economy network in China developed rapidly, Guangdong, Jiangsu, and Shandong occupy a central position in the network. The development of the internet is characterized by the diffusion from the center to the surrounding areas and then to the periphery. The digital economy network can significantly affect carbon emissions. The higher the level of development of the local digital economy network, the more conducive it is to promoting carbon reduction, while the lower the status of the digital economy network, the less conducive it is to promoting carbon reduction. Economic development and energy intensity are important indirect channels through which the digital economy network affects carbon emissions. Therefore, the formulation of relevant policies should attach great importance to the differences of regional digital economy by means of the measures like information sharing, technology spillover, and resource allocation. The network effect of the digital economy should be leveraged to achieve coordinated development among regions in the digital economy and effectively promote carbon reduction.
