互联网技术进步空间溢出效应与碳排放——基于空间模型的实证研究

Internet Technology Progress Space Spillover Effect and Carbon Emissions—Empirical Research Based on Spatial Model

摘要: 大数据时代的到来意味着经济增长越来越依托于互联网技术发展，而经济增长又与碳排放有着紧密联系，因此有必要通过实证检验互联网技术进步与碳排放的关系。本文使用2011~2016中国30个省市的空间面板数据，基于环境库兹涅兹曲线(EKC)，应用空间杜宾模型(SDM)剖析互联网技术进步对碳排放的空间溢出效应。实证结果显示：互联网技术进步与碳排放均存在空间溢出效应；互联网技术进步增加本地区碳排放量，而对于邻近地区碳排放不存在显著的促进作用；经济增长与碳排放存在明显的倒“U”型关系。

Abstract: The arrival of the era of big data means that economic growth is increasingly dependent on the development of Internet technology, and economic growth is closely linked to carbon emissions, so it is necessary to test the relationship between Internet technology progress and carbon emissions through empirical tests. This article uses the spatial panel data of 30 provinces and cities in China from 2011 to 2016 based on the environmental Kuznets Curve (EKC), and uses the spatial Dubin model (SDM) to analyze the spatial spillover effect of Internet technology progress on carbon emissions. The empirical results show that there is a spatial spillover effect between Internet technology progress and carbon emissions; Internet technology progress increases the carbon emissions of the region, but there is no significant promotion effect on the carbon emissions of neighboring regions; economic development has a significant “U”-type relationship with carbon emissions.
