With 2008-2020 China's provincial panel data as the research object, we use the entropy weight method to compute green finance and pollution, and we empirically study the scope of the spillover effects and threshold impacts of green finance on environmental pollution using the spatial Durbin model and threshold regression model. The findings are as follows: first, under different spatial weight matrices, green finance has a spatial spillover effect on pollution. And the effect boundary is approximately 500 km. Second, with the low-carbon energy transition, technological progress, and green finance as threshold variables, there are a single threshold, single threshold, and double threshold, respectively, that have significant threshold effects. Third, the spillover and threshold effects of green finance on pollution differ by region. The indirect effect is negative in the eastern region and positive in the central and western regions. There is a single threshold effect of low-carbon energy transition and green finance in the western region, a single threshold effect of green finance in the central region, and a single threshold effect of technological progress in the eastern region. On this basis, we put forward. specific policy recommendations.
以 2008-2020 年中国省级面板数据为研究对象,运用熵权法测算绿色金融和污染排放指标,采用空间 Durbin 模型和门槛回归模型实证研究绿色金融对环境污染的溢出效应和门槛影响范围。研究结果表明:第一,在不同空间权重矩阵下,绿色金融对污染排放具有空间溢出效应,作用边界约为 500km。第二,以低碳能源转型、技术进步和绿色金融为门槛变量,分别存在单一门槛、单一门槛和双重门槛,均具有显著的门槛效应。第三,绿色金融对污染排放的溢出和门槛效应存在区域异质性,东部地区为负向间接效应,中西部地区为正向间接效应;西部地区低碳能源转型和绿色金融存在单一门槛效应,中部地区绿色金融存在单一门槛效应,东部地区技术进步存在单一门槛效应。在此基础上,提出了具体的政策建议。
