摘要
文章基于2014—2020年中国823个省际边界县域面板数据,刻画了数字金融发展水平和碳排放强度的时空格局特征,并运用STIRPAT模型、空间杜宾模型检验了数字金融对碳排放强度的影响及其空间效应。结果表明:①2014—2020年省际边界县域数字金融发展水平不断提升,整体呈“东高西低”的空间格局;碳排放强度呈现下降趋势,西部地区省际边界县域是高碳排放强度的主要集聚地。②省际边界县域数字金融发展能显著降低碳排放强度,并表现出较强的稳定性。③省际边界县域数字金融发展对本地碳排放强度呈抑制效应,但会增加扩大相邻县域碳排放强度,且存在显著的区域异质性。④省际边界县域数字金融通过产业结构升级效应、技术创新效应能够显著降低碳排放强度。最后,文章提出了以数字金融促进碳减排的核心战略及优势驱动、因地制宜与协同合作的发展策略。
This paper visualizes the spatiotemporal patterns of digital finance development level and carbon emission intensity on the basis of the panel data of 823 counties in China's provincial borders from 2014 to 2020.It also employs the STIRPAT model and Spatial Durbin Model to test the impact of digital finance on carbon emission intensity in counties of China's provincial borders.The results show that:1)From 2014 to 2020,the development level of digital finance has been continuously improved in counties of China's provincial borders,presenting an overall spatial pattern of being higher in the east and lower in the west.Carbon emission intensity showed a downward trend,counties in the west of provincial borders are the main agglomeration areas of high carbon emission intensity.2)The development of digital finance in counties of China's provincial borders has a significant inhibitory effect on carbon emission intensity,showing strong stability.3)The development of digital finance in counties of China's provincial borders has an inhibitory effect on the local carbon emission intensity,but it increases the carbon emission intensity of adjacent counties,and there is significant regional heterogeneity in the impact of digital finance on carbon emission intensity in counties of China's provincial borders.4)The digital finance in counties of China's provincial borders can significantly reduce carbon emission intensity through the effects of industrial structure upgrading and technological innovation.In response to the specific conditions of counties of China's provincial borders,this paper proposes a core strategy of reducing carbon emission intensity through digital finance,as well as development strategies featuring advantage-driven growth,adaptation to local conditions and collaborative cooperation.
