摘要： 立足于中介效应视角，本文从技术创新、产业结构、环境分权三个方面探讨环境规制对区域碳生产率影响的理论机制，并以此为基础，进一步运用2008-2015年中国30个省市区面板数据考察环境规制对区域碳生产率的门槛效应及空间溢出效应。实证结果显示：地方政府竞争背景下，环境规制对区域碳生产率的影响会随技术创新、产业结构以及环境分权变化而发生根本性转变。换言之，在不同技术创新、产业结构、环境分权水平条件下，环境规制对区域碳生产率的净效应分别呈现V型、倒V型、倒V型门槛特征；邻近地区间环境规制与区域碳生产率均存在局部聚集的空间特征，表现为明显的正向溢出效应。为实现2030年减排承诺的目标，除选择适宜的环境规制方式、力度以外，还需要从技术创新、产业结构、环境分权及区域协调等多个方面，优化环境规制的区域碳生产率效应的实施效果。

Abstract: Based on the intermediate perspective, this paper studies the theoretical influencing mechanism from technological innovation, industrial structure and environmental decentralization. Then this paper estimates the threshold effects and spatial spillover effects of environmental regulation on regional carbon productivity based on the panel data of 30 provinces in China from 2008 to 2015. The empirical conclusion shows that, the regional carbon productivity effects of environmental regulation has a structural change with the changes of local technological innovation level, industrial structure deviation and environmental decentralization under the local governmental competition. In other words, under the different technical innovation levels,industrial structures and levels of environmental decentralization,the net effect of environmental regulation on regional carbon productivity shows a ′V′ type,inverted ′V′ type and inverted ′V′ type threshold characteristic respectively;both environmental regulation and regional carbon productivity in adjacent areas have spatial characteristics of local aggregation, which shows obvious positive spillover effect.In order to realize the target of emission reduction commitment, we should promote the practical effects of the environmental regulation on the regional carbon productivity from technological innovation, industrial structure adjustment, environmental decentralization and regional coordination, except for setting the suitable pattern and strength of environmental regulation.
