江苏省太湖流域工业水环境监管体系构建

Industrial Water Environment Regulation System Construction in Taihu Lake Basin of Jiangsu Province

为解决水环境质量与经济发展矛盾的问题,研究行之有效的工业水环境监管体系。对江苏省太湖流域现行工业水环境监管体系的现状进行分析,提出其中存在的关键问题。从监管参与主体的委托-代理关系出发,采用信号博弈的理论方法,构建委托-代理关系的博弈模型,并得出博弈均衡,对江苏省太湖流域现行工业水环境监管体系构建进行模型分析。结果表明:增加地方官员纵容污染的政治成本,提高公众参与的程度,对于实现地方政府与排污企业的博弈均衡、保障监管有效实施有着重要作用。在此基础上,构建江苏省太湖流域工业水环境监管体系。变革传统监管体系中地方政府作为唯一监管主体,为兼容上级政府的行政、司法监督和公众等社会性监督的中央-地方-公众合作监管体系。形成了核心层面与辅助层面组成的双层监管结构,以及自上而下监管和自下而上监督的双向监管模式。最后为江苏省太湖流域设计中央-地方-公众合作的工业水环境监管体系运行流程。

This paper aims to propose an effective regulation system for industrial water environment, in order to handle the conflict between water environmental quality and economic development. Firstly, the current industrial water environmental regulation system in Taihu Lake Basin of Jiangsu Province is analyzed, and the key problems in the system are pointed out. Then, we establish a game model of principal-agent relationship with the aid of the regulators＇ principal-agent relationship and also the signaling game theory. Moreover, the equilibrium state is obtained from this model. The construction of the industrial water environmental regulation system in Taihu Lake Basin of Jiangsu Province is further analyzed by the model. The results show that an increase in the political costs due to pollution connived by local officials and the improvement in public participation, can achieve a game balance between local government and sewerage enterprise, and also promote the regulation implementation effectively. Furthermore, we propose an effective regulatory system for the industrial water environmental in Taihu Lake Basin of Jiangsu Province, which has turned from the traditional regulatory system with local government as the sole regulatory body, to the central-local-public cooperated regulation system with administrative and judicial supervision from government of higher levels, and also social supervision from the public. This system forms a two-tier regulatory structure with a core level and secondary level, and a hi-directional regulatory model with top-down regulation and bottom-up supervision. Finally, a running process of this regulation system is designed for the Taihu Lake Basin of Jiangsu Province.
