产业升级视角下绿色信贷与环保财政政策协同效应研究

单一的绿色信贷政策或环保财政政策在促进环境治理、产业升级等方面存在局限性。因此，首先在阐述绿色信贷政策和财政政策作用机理的基础上，给出二者可能的政策协同渠道。然后，利用2007—2016年省际面板数据，考察绿色信贷与环保财政政策在促进产业升级方面是否存在协同效应，并对有可能增强二者协同效果的相关因素进行检验。结果表明：绿色信贷与环保财政政策存在显著协同效应，并且绿色信贷与税收政策的协同效果优于其与支出政策的协同效果，而金融发展水平能够显著促进绿色信贷与环保财政政策协同。此外，考察了政策协同与单位能耗及单位污染排放的关联性，得出了相似的结论。

Research on the Synergy between Green Credit and Environmental Fiscal Policy

A single green credit policy or environmental fiscal policy has limitations in environmental governance and industrial upgrading. Therefore, on the basis of explaining the mechanism of green credit policy and fiscal policy respectively, this paper gives the possible channels of policy synergy between them. Then, using the provincial panel data from 2007 to 2016, this paper examines whether there is synergy between green credit and environmental fiscal policy in promoting industrial upgrading, and examines the relevant factors that may enhance the synergistic effect between them. The empirical results show that there is a significant synergistic effect between green credit and fiscal policy, and the synergistic effect between green credit and tax policy is better than that between green credit and expenditure policy, while the level of financial development can significantly promote the synergy between green credit and environmental fiscal policy. In addition, the paper also examines the relationship between policy synergy and unit energy consumption and unit pollution emissions, and draws similar conclusions.
