The digital economy and the green economy are two major issues for economic recovery in the post epidemic era. From spatial interaction spillover, we analyze and measure the relationships between the digital economy and environmental pollution in 287 prefecture-level cities in China from 2008 to 2018 using simultaneous spatial equations and the generalized 3-stage least square (GS3SLS) method. The results show that: (1) there is a reverse and complex spatio-temporal evolution of the digital economy and environmental pollution in Chinese cities. (2) There is a spatial interaction spillover effect between the digital economy and environmental pollution. Local digital economy and environmental pollution inhibit each other. The digital economy and environmental pollution have a significant spatial spillover. The digital economy of surrounding regions has a suppressive effect on local environmental pollution. The environmental pollution of surrounding cities has a crowding-out effect on the local digital economy. (3) Digital economy suppresses environmental pollution through the green development effect and innovative development effect; environmental pollution suppresses the digital economy through the talent crowding out effect and the policy tightening effect. The conclusion of this paper provides evidence for the coupling and coordinated development between the digital and green economy, which is of great significance for promoting the transformation of economic development modes and realizing green and high-quality development.
数字经济和绿色经济是后疫情时代经济复苏的两大关键。本文基于空间交互溢出效应，利用同时空间方程和广义 3 阶段最小二乘法（GS3SLS），测度了 2008—2018 年中国 287 个地级市的数字经济与环境污染之间的关系。结果表明：①中国城市的数字经济与环境污染存在反向且复杂的时空演变特征。②数字经济与环境污染之间存在空间交互溢出效应，本地数字经济和环境污染存在相互抑制的作用，数字经济和环境污染具有显著的空间溢出效应，周边地区的数字经济对本地环境污染具有抑制作用，周边城市的环境污染对本地数字经济具有挤出效应。③数字经济通过绿色发展效应和创新发展效抑制环境污染，而环境污染通过人才挤出效应和政策收紧效抑制数字经济。本文结论为数字经济与绿色经济的耦合协调发展提供了证据，对推动经济发展方式转变、实现绿色高质量发展具有重要意义。
