【摘要】：针对我国碳税最优税率确定问题,本文构建了涉及碳排放企业、减排产品生产企业、政府规制部门三方的完全信息静态博弈模型,分析了影响参与方行为策略均衡的关键变量,并讨论了碳税最优税率确定的影响因素。研究结果认为,碳排放企业和减排产品生产企业所在市场的结构决定了碳税最优税率的大小:当两个市场都接近完全竞争市场的时候,碳税最优税率等于每单位二氧化碳排放所造成的边际社会损失;当碳排放企业所在市场接近完全竞争市场,而减排产品生产企业所在市场由几家企业垄断时,政府规制部门应该设定高于碳排放边际社会损失的碳税税率;当减排产品生产企业所在市场接近完全竞争市场,而碳排放企业所在市场由几家企业垄断时,政府规制部门设定的碳税税率应该低于碳排放边际社会损失;当两个市场都具有一定的垄断力量,则此时碳税最优税率是不确定的,关键要看哪个市场垄断力量相对较大。另外,碳税税率水平还受企业技术水平的影响,企业减排技术水平的提高会影响政府规制的效果。
[Abstract]:Aiming at the problem of determining the optimal tax rate of carbon tax in China, this paper constructs a complete information static game model involving carbon emission enterprises, producers of emission reduction products, and government regulation departments, and analyzes the key variables that affect the equilibrium of participants' behavior strategies. The results show that the structure of the market in which carbon emitters and producers of carbon abatement products are located determines the size of the optimal tax rate: when both markets are close to completely competitive markets, The optimal rate of carbon tax is equal to the marginal social loss per unit of carbon dioxide emissions; when the market in which the carbon emitter is located is close to a fully competitive market, and the market in which the emission-reducing products are manufactured is monopolized by several companies, Government regulators should set a carbon tax rate higher than the marginal social loss of carbon emissions; when the market in which emission-reducing products are manufactured is close to a fully competitive market where carbon emitters are monopolized by several companies, The carbon tax rate set by the government regulation department should be lower than the marginal social loss of carbon emissions. When both markets have a certain monopoly power, the optimal carbon tax rate is uncertain. In addition, the level of carbon tax rate is also affected by the technological level of enterprises, and the improvement of enterprise emission reduction technology level will affect the effect of government regulation.
