| With China’s rapid economic development, people’s living standards continued to improve, but the adverse effects of environmental pollution have gradually emerged. The contradictions of economic development and environmental pollution has become the problem which must be addressed in the economic and social development process. As the main body of pollution emissions, enterprise has the bounden duty of environmental protection. However, the externalities of environmental pollution make it extremely difficult to the coordinate effectively of environmental and economic benefits. To solve this problem,experts and scholars have proposed the emissions trading system. Under this system, emission rights has become a scarce resource. Enterprises who have ability of energy saving can benefit from emissions trading and have the power of energy saving and emission reduction naturally. Enterprises who do not have ability of energy saving can reduce costs of pollution emissions through the purchase of emission rights. Not only polluting industries and abatement enterprises can benefit from it.Government can also achieve the best reduction results at the lowest cost.From the practice of the United States to the European carbon emissions trading, Emission trading has been paid more and more attention. Our country start test of Emission trading In the last century eighty’s in Shanghai and Promote different types of emissions trading pilot in cooperation with the U.S. Environmental Protection Association in2001.China’s emissions trading mode is gradually established. However, the problems of "zero supply","gray trading", Irregular market and the lack of effective supervision in emissions trading market has affected emission rights trading function in environmental protection. How to improve the emissions trading institutional arrangements, reduce transaction costs and improve operational results has become the problems in the face of China’s environmental management.On the basis of introduction on emission trading cost control theories, analysis emissions trading cost control problems and the cause of the problems. Suppose the firm as a rational person, the sum of the maximum emission rights market supply is not greater than the corporate share of the initial emission rights, the existence of government punishment cost, transaction costs are rising with the trading volume and the existence of Emissions trading financing costs and other conditions. Construction cost control model of emissions trading,analyze the model in theoretical and case studies, and offer proposals for strengthening cost control of the emissions trading to maximize the return. On the macro level, provide a reference to the improvement of China’s emissions trading system, improve China’s environment in general, and Make our country make contributions to the improvement of global environment as a great nation image; At the micro level, allows enterprises to control the cost impact factors better through the application of emissions trading cost control model and achieve the maximum economic benefit at the same time to performing social responsibility. |
