数字金融对区域绿色创新的空间效应

通过空间相关性检验和构建空间权重矩阵,采用31个省（区、市）的面板数据,运用空间杜宾模型实证分析数字金融对区域绿色创新水平的空间影响效应。结果表明：数字金融能显著促进本区域绿色创新,但抑制周边地区发展,并且两者具有空间聚集性;从异质性分析来看,主要是数字金融使用深度分指数和中部地区的空间效应较为显著。最后提出因地制宜发展数字金融等相关建议。

The Spatial Effect of Digital Finance on Regional Green Innovation

Through the spatial correlation test and the construction of spatial weight matrix, the panel data of 31 provinces , autonomous regions and municipalities were used to empirically analyze the spatial effects of digital finance on regional green innovation level by using the spatial Dubin model. The results show that digital finance can significantly promote green innovation in this region, but inhibit the development of surrounding area, and they have spatial aggregation. From the perspective of heterogeneity analysis, the spatial effect of digital finance usage depth index and central region is more significant. Finally, some suggestions are put forward, such as developing digital finance according to local conditions.
