绿色金融、数字经济与环境污染

Green Finance ,Digital Economy and Environmental Pollution

以2011—2020年的省际数据作为研究对象,采用空间面板和门限面板模型实证探究了绿色金融和数字经济对环境污染的空间溢出效应以及门限效应。研究发现:在不同地理、经济空间权重矩阵下,绿色金融对环境污染同时具有显著的负向空间溢出效应;在数字经济与经济发展水平作为门限变量的作用下,两者均存在单一门限值,均具有明显的门限效应;在引入数字经济作为调节变量时,数字经济能够对绿色金融改善环境污染起到一个有益的补充作用。由此,研究完善了环境污染理论体系,强调在深化绿色金融发展的同时,应不断优化数字经济的覆盖面,进而引导其成为助推绿色金融改善环境污染的核心调节力量。

Based on the provincial data from 2011 to 2020,this paper empirically explores the spatial spillover effect and threshold effect of green finance and digital economy on environmental pollution by using spatial panel and threshold panel models.Results show that under different geographical and economic spatial weight matrices,green finance has a significant negative spatial spllover effect on environmental pollution.Under the influence of digital economy and economic development level as threshold variables,both of them have single threshold value and have obvious threshold effect.When the digital economy is introduced as a regulatory variable,digital economy can play a beneficial supplement and perfect for green finance to improve environmental pollution.Therefore,it has relatively perfected the theoretical system of environmental pollution,emphasizing that while deepening the development of green finance,it is necessary to continuously optimize the coverage of digital economy,and then guide digital economy to become the core regulatory force to promote green finance to improve environmental pollution.
