环境规制、技术创新与产能利用率——兼论“环保硬约束”如何有效治理产能过剩

Environmental Regulation,Technological Innovation and Governance of Excess Capacity——Study on How to Effectively Control Excess Production Capacity under “Environmental Protection Hard Restraint”

基于中国制造业的细分行业数据,利用面板门槛模型考察了不同环境规制强度和技术创新程度下环境规制对产能利用率的差异化效应,对"环保硬约束"如何有效治理产能过剩给出解释说明。结果表明:环境规制对产能利用率具有显著的非线性门槛特征,随着环境规制强度的不断增加,环境规制对产能利用率的影响由不显著变为显著,影响方向由促进变为抑制,只有适当的环境规制才有利于缓解产能过剩。随着技术创新程度的不断提升,环境规制对产能利用率具有先抑制后促进的作用,技术创新程度的不断提高强化了环境规制的创新补偿效应,有利于促进产能过剩化解。

With data of subdivided industries in Chinese manufacturing,this paper examines the differential effects of different environmental regulation intensity and different degree of technological innovation on the capacity utilization through the panel threshold model,how the"green hard constraints"to effectively govern excess capacity is explained.The results show that the environmental regulation has a significant feature of nonlinear threshold on the capacity utilization rate,with the increase of the intensity of environmental regulation,the effect of environmental regulation on the capacity utilization changed to significant influence from insignificant influence and the direction changed to restraint from promoting,only the appropriate environmental regulation will be conducive to resolving the excess capacity in manufacturing.With the continuous improvement of the degree of technological innovation,the impact of environmental regulation on capacity utilization shows first inhibition and then promotion,the continuous improvement of the technological innovation strengthens the compensation effect of environmental regulation,and promotes the resolution of excess production capacity.
