摘要
在推进污染防治攻坚战的背景下,挖掘政府补贴对工业企业污染减排的作用对于中国加快发展方式绿色转型和产业高质量发展具有重要意义。基于中国工业企业微观数据,系统评估了政府补贴对企业污染排放的影响效应及作用机制。研究发现:政府补贴显著降低了企业的污染排放强度,并且这一作用在东部和西部地区较为明显,而在中部地区并不显著;另外,政府补贴对国有企业和民营企业污染排放的抑制效应更为突出。进一步的机制检验表明,创新效应、规模效应和政府监管效应是政府补贴影响企业污染排放的重要途径。拓展分析发现:政府补贴的污染减排效应并不具有持续性,只有当补贴强度保持在一定的适度区间时,才能对企业污染减排发挥作用;另外,政府补贴通过降低企业的污染排放强度最终能够促进企业生产率的提升,证实了政府补贴污染减排效应对企业高质量发展的推动作用。研究对于今后如何设计政府政策以降低企业污染排放和建立健全环境治理体系具有一定的参考价值。
Against the background of the battle of pollution prevention and control,it is of great significance to explore the role of government subsidies in industrial firms’reduction in pollution in order to accelerate the green transformation of China’s development and the high-quality development of its industry.Based on industrial micro-firm data,this paper systematically evaluates the effect of government subsidies on firms’pollution emissions and its mechanism.The study finds that government subsidies significantly reduce the intensity of firms’pollution emissions,and that the effects are more obvious in the eastern and western regions,but not in the central region;in addition,government subsidies have a more restraining effect on the pollution emissions of state-owned and private firms.Furthermore,the results of the mechanism test show that innovation,scale,and government supervision are important channels through which government subsidies affect firms’pollution emissions.An extended analysis also reveals that the effect on pollution reduction of government subsidies is not sustainable,and that it can only help to reduce pollution when the subsidy intensity is maintained within a certain moderate range.Furthermore,government subsidies can upgrade firm productivity by reducing the intensity of pollution emissions,confirming the influence of government subsidies on pollution reduction to push forward firms’high-quality development.This research has value as a reference for how to design government policies to reduce firm pollution emissions and establish a sound environmental governance system in the future.
