摘要
环境规制的增强并不必然带来碳生产率的提升,其影响效应会受到空间相关性及环境规制类型的影响。本文运用空间杜宾模型检验了异质性环境规制对地区碳生产率的直接影响及空间溢出效应,研究结论显示:(1)我国省级碳生产率在2003—2017年均呈不断上升的趋势,且空间滞后系数显示各地区碳生产率、技术进步指数及效率进步指数均会显著受到邻近地区的正向影响,表现出“一荣俱荣,一损俱损”的特征;(2)强制型的环境规制对本地区碳生产率的直接影响显著为正,但对邻近地区的碳生产率则存在负向溢出效应,表现出“严格污染管制下的就近转移”特征;市场型的环境管制对本地区碳生产率的直接效应显著为正,对邻近地区碳生产率的影响存在正向溢出效应,表现为“近朱者赤,近墨者黑”的特征。自愿型的环境规制对地区碳生产率的直接效应和间接效应均不太显著,可能是我国公众环保意识及自觉性不够,使得环境规制存在门槛效应。为此,应设计适合各地区相适应的环境规制政策,加强环境治理政策的联动性和协调性,积极发挥碳生产率正向的空间外溢效应,提升整体区域的碳生产率水平。
Enhanced environmental regulation does not necessarily lead to an increase in carbon productivity,and its impact will be affected by spatial correlation and types of environmental regulation.The paper examines the direct impact of heterogeneous environmental regulation on regional carbon productivity and spatial spillover effect by using spatial Durbin model.The results show that:(1)China’s provincial carbon productivity shows a rising trend from 2003 to 2017,and the spatial lag coefficient shows that the carbon productivity,technological progress index and efficiency progress index of all regions will be significantly affected by the neighboring regions,showing the characteristics of"both prosperity and loss".(2)The direct impact of mandatory environmental regulation on carbon productivity in the region is positive,but there is a negative spillover effect on carbon productivity in the neighbouring areas,showing the characteristics of"near transfer under strict pollution control";The direct effect of market-based environmental regulation on carbon productivity in the region is significantly positive,and the effect on carbon productivity in the neighbouring areas is positive spillover effect,which is characterized by"near-zhu is red,near-ink is black".The direct and indirect effects of voluntary environmental regulation on regional carbon productivity are not significant,which may be due to the lack of public awareness and consciousness of environmental protection,making environmental regulation have a threshold effect.Therefore,we should design appropriate environmental regulation policies for different regions,strengthen the linkage and coordination of environmental governance policies,actively exert the positive spatial spillover effect of carbon productivity,and enhance the overall regional carbon productivity level.
