环境规制、技术创新对全要素碳生产率的影响研究——基于中国省域的空间面板数据分析

Research on the Impact of Environmental Regulation and Technical Innovation on Total Factor Carbon Productivity --Based on the Chinese Provinces Spatial Panel Data Analysis

摘要:

为探究环境规制政策是否能够实现碳减排和经济增长的“双红利”,本研究采用松弛模型的方向距离函数(SBM-DDF)模型和空间面板计量方法,通过测算2006-2016年中国省域全要素碳生产率,刻画中国省域全要素碳生产率的空间特征,进一步厘清环境规制、技术创新对全要素碳生产率的影响机理。研究结果显示：(1)中国各省份全要素碳生产率存在显著的空间集聚特征,其中高-高集聚(H-H)省份多位于东部沿海发达地区,而低-低集聚(L-L)省份多位中西部欠发达地区；(2)环境规制会促进全要素碳生产率的提升,且环境规制对全要素碳生产率的“本地效应”大于“邻地效应”；(3)技术创新在环境规制对全要素碳生产率的影响中存在部分中介效应。

Abstract:

To explore whether environmental regulation policies can realize "double dividend" of carbon emission reduction and economic growth, In this paper using the directional distance function (SBM-DDF) model and Space panel metering method, by measuring panel data from china’s 30 provinces covering the year from 2006 to 2016, describes the spatial characteristics of total factor carbon productivity in Chinese provinces ,further clarify the impact mechanism of environmental regulation and technological innovation on TFP. The results show that :1)Among the provinces in China, the total factor carbon productivity has significant spatial agglomeration characteristics, among which, the high-high agglomeration (H-H) provinces are mostly located in the developed eastern coastal areas, while the low-low agglomeration (L-L) provinces are mostly in the less developed central and western regions.2) Environmental regulation can significantly promote the improvement of TFP, and the "local effect" of environmental regulation on TFP is greater than the "neighborhood effect".3) TechnicalSinnovation has some mediating effect in the influence of environmental regulation on total factor carbon productivity.
