基于空间杜宾模型的绿色金融经济增长效应研究

Research on the effect of green finance on economic growth based on spatial Dubin model

为研究绿色金融对经济增长的效应,首先利用2011‑2020年我国各省份绿色金融面板数据,基于熵权法测度各省域的绿色金融发展体系,建立空间杜宾模型,分析基于地理位置的0‑1空间权重矩阵下我国各省域绿色金融对经济增长的影响效应,同时进行适配性检验和稳健性检验。研究结果表明绿色金融对本地区经济增长呈显著的正向效应,邻近地区的绿色金融发展对本地区经济增长呈负向效应;政府支出对本地区经济增长呈正向效应,对邻近地区呈负向效应,绿色金融的发展有待培育和完善。

In order to study the effect of green finance on economic growth,we first use the panel data of green finance in China′s provinces from 2011 to 2020 to measure the green finance development system in each province based on the entropy weight method,and then establish a spatial Dubin model to analyze the impact of green finance on economic growth in China′s provinces under the 0-1 spatial weight matrix based on geographical location,and conduct fitness test and robustness test.Finally,the conclusion is drawn that green finance has a significant positive effect on regional economic growth,and the development of green finance in neighboring regions will have a negative effect on regional economic growth;The government expenditure has a positive effect on the regional economic growth,and a negative effect on the neighboring regions;The development of green finance needs to be cultivated and improved.
