环境规制、企业异质性与国有企业过剩产能治理

Environmental regulation,enterprise heterogeneity and state-owned enterprises’ overcapacity management

在异质性企业框架下引入环境约束与政企合谋因素,考察了国有企业过剩产能的形成机理与治理机制。在此基础上,通过改进的生产函数法测度企业层面的产能利用率,并分别采用面板Tobit模型与生存分析模型实证检验环境规制对国有企业过剩产能治理的影响。研究结果表明,环境规制不仅能够提升国有企业的产能利用率,同时会提高落后产能企业市场退出的概率,即能够从集约边际与扩展边际两方面实现国有企业的产能治理。此外,通过区分行业污染强度与外部需求条件的估计结果表明,环境规制对于污染程度较强和出口参与型企业的产能治理效果更加显著。

Under the framework of heterogeneous enterprises,we introduce environmental constraints and collusion and investigate the formation mechanism and governance mechanism of excess capacity in state-owned enterprises. On this basis,we use the improved production function method to measure the capacity utilization ratio of state-owned enterprise,and then we use the panel Tobit model and survival analysis model to test the effect of environmental regulation on the management of excess capacity of state-owned enterprises. The results show that environmental regulation can not only improve the capacity utilization of state-owned enterprises,but also improve the probability of market backward production enterprises’ withdrawal,that is,it can realize the capacity management of state-owned enterprises from the intensive margin and the extensive margin.In addition,the estimation results with different pollution intensity and external demand conditions show that environmental regulation has more significant control effects on pollution-participating enterprises.
