行政垄断约束下环境规制对工业生态效率的影响——基于动态空间杜宾模型与门槛效应的检验

The impact of environmental regulation on industrial ecological efficiency under the constraints of administrative monopoly:based on dynamic spatial durbin model and threshold effect

中国特色政治经济管理体制下,环境规制对工业生态效率的影响会受到行政垄断的约束。首先,将行政垄断与环境规制纳入生产函数,构建了环境规制与行政垄断影响生态效率的理论框架。其次,利用Super-SBM模型测算了中国2000—2015年30个省份的工业生态效率,结果表明,中国工业生态效率整体呈上升趋势,东部地区显著高于中西部地区。最后,构建动态空间杜宾模型检验环境规制和地区性行政垄断对工业生态效率的影响,结果显示,环境规制对工业生态效率具有正向影响,而且环境规制存在空间溢出效应和区域异质性。考虑到不同地区行政垄断程度存在差异,进一步设定面板门槛模型进行检验,结果发现,当地区性行政垄断程度低于门槛值0. 343时,环境规制有效提升工业生态效率,当地区性行政垄断程度超过门槛值时,环境规制的系数不显著。据此提出制定异质性环境规制政策、放松地区性行政垄断、建立企业清洁生产技术研发激励机制、提高人力资本水平的政策建议。

Under the political and economic system with Chinese characteristics,the influence of environmental regulation on industrial eco-efficiency will be subject to administrative monopoly. First,we integrate administrative monopoly and environmental regulation into production function,and construct the theoretical framework of the impact of environmental regulation and administrative monopoly on eco-efficiency. Then,we employ the Super-SBM model to measure the industrial eco-efficiency of 30 provinces in China from 2000 to 2015. The results show that China＇s industrial eco-efficiency is generally rising,and the eco-efficiency in eastern region is significantly higher than that in central and western regions. Finally,the dynamic spatial panel model is constructed to test the impact of environmental regulation and local administrative monopoly on industrial eco-efficiency. The empirical results show that environmental regulation has a positive impact on industrial ecoefficiency,and environmental regulation has significant spatial spillover effects and obvious regional heterogeneity.Considering the regional heterogeneity of the degree of administrative monopoly,we further investigate it with the panel threshold model. The results show that environmental regulation is conducive to improve efficiency of industrial eco-efficiency when the degree of local administrative monopoly is lower than the threshold value of 0. 343,and the coefficient of environmental regulation is not significant when the degree of local administrative monopoly exceeds the threshold. Related to our analysis,some suggestions such as heterogeneous environmental regulation policies,reduction of local administrative monopoly,construction of the incentive mechanism of the RD on firm＇s clearer production technology,and improvement of human capital are provided.
