工业科技金融发展如何影响绿色全要素生产率?

How Does the Development of Industrial Sci-Tech Finance Affect Green Total Factor Productivity?

利用2012—2021年中国30个省份的工业数据,利用非导向EBM超效率模型、熵值法和空间杜宾模型,实证检验工业科技金融发展对工业绿色全要素生产率的影响、调节效应和空间效应。结果表明,工业科技金融显著提升其绿色全要素生产率,提升效应在东部区域更加明显。数字普惠金融对二者的关系具有反向调节作用,技术多样化对二者的关系具有正向促进作用。进一步考察工业科技金融对工业绿色全要素生产率的空间效应发现,工业科技金融发展只对本省份的工业绿色全要素生产率有着促进作用,但对外围地区不具有空间溢出效应。最后,为促进工业绿色全要素生产率提升提供政策建议。

This paper uses industrial data from 30 provinces in China from 2012 to 2021,and uses the non-guided EBM super-efficiency model,entropy method and spatial Durbin model to empirically test the impact,moderating effect and spatial effect of industrial sci-tech finance development on industrial green total factor productivity.The results show that industrial sci-tech finance can significantly improve its green total factor productivity,and the improvement effect is more obvious in the eastern region.Digital inclusive finance has a negative regulatory effect on the relationship between the two,and technological diversification has a positive promoting effect on the relationship between the two.Further examination of the spatial effect of industrial sci-tech finance on industrial green total factor productivity found that the development of industrial sci-tech finance only promotes the province's industrial green total factor productivity,but does not have a spatial spillover effect on peripheral areas.Finally,this paper provides policy suggestions for promoting industrial green total factor productivity.
