本文对环境治理目标进行了重新定位,认为环境治理的核心问题是依靠污染物排放量的最优化而非最小化实现社会成本的最小化。进而在成本分析的框架下构建了一种以总量控制为基础的排污权交易机制模型,考察排污权交易机制在环境治理方面对社会成本的影响。研究发现,建立低成本的完善的排污监管机制是建立有效的排污权交易机制的关键条件,政府部门可通过降低监管成本,提高污染物处理能力,加强直接投入治污费用的利用效率等方法有效提高治污效率,节约社会成本。
In this paper, the goal of environmental governance has been repositioned, and the core issue of environmental governance is to minimize the cost of society by relying on the optimization of pollutant emissions instead of minimization. In the framework of cost analysis, this paper constructs a model of emission trading mechanism based on total quantity control and examines the impact of emissions trading mechanism on social costs in environmental governance. The study found that the establishment of a sound low-cost pollution control mechanism is to establish an effective emission trading mechanism of the key conditions for government departments can reduce regulatory costs, improve pollutant disposal capacity, and enhance the efficiency of direct investment in pollution control costs and other methods to effectively Improve pollution control efficiency, save social costs.
