Abstract: Based on the coupling effect between policies under the "new normal" as a breakthrough point, this paper explores the mechanism of government subsidies cooperating with environmental regulation to impel industrial upgrading, and empirically tests the impact of the coupling effect between environmental regulation and government subsidies on industrial restructuring and upgrading by using China's inter-provincial panel data from 2007 to 2015. The study finds that the impact of environmental regulation on industrial structure upgrading presents a significant "threshold" feature. The coupling effect of environmental regulation and government R&D subsidy policy can significantly promote industrial structure upgrading, but there is obvious regional and regulatory heterogeneity. This paper further explores the mechanism of the effect of policy coupling on the upgrading of industrial structure. The results show that the policy coupling effect does not show an effective mitigation effect on the cost of compliance, but can significantly enhance the "innovation compensation effect" and thus play a positive role in promoting the upgrading of industrial structure.This paper concludes that diversified policy mix is of great significance for giving full play to complementary advantages among policies and promoting industrial upgrading.

摘要： 本文以“新常态”下政策间耦合效应为切入点，分析政府研发补贴配合环境规制倒逼产业结构升级的作用机制，并利用2007-2015年中国省际面板数据，实证检验环境规制与政府研发补贴耦合效应对产业结构升级的影响。研究发现：环境规制与产业结构升级之间呈现显著的U型曲线关系，环境规制与政府研发补贴政策耦合效应能够有效促进产业结构升级，但存在明显的地区与规制类型异质性。本文还进一步探讨了政策耦合效应对产业结构升级影响的作用机制，结果表明：政策耦合效应并未表现出对“遵循成本”有效的缓解作用，但能够显著增强“创新补偿效应”，从而对产业结构升级产生积极的促进作用。本文研究结论说明多元化的政策组合，对于发挥政策间的优势互补、促进产业升级具有重要意义。
