碳税规制的清洁技术偏向效应研究——一个分工视角

Research on the effect of carbon-tax environmental regulation on the tendency of clean energy:The perspective of division

基于迂回生产的超边际分析,文章构建一个使用中间技术(污染技术或清洁技术)迂回制造最终产品的理论模型,从分工视角研究了碳税规制(排污税或减排补贴)影响清洁技术偏向的微观机理,揭示出污染型完全分工模式、清洁型完全分工模式和过渡型完全分工模式结构对碳税规制的清洁技术偏向效应具有异质性。具体结论表明:政府实施碳税规制(排污税、减排补贴等)会对清洁技术偏向产生显著正向效应,并且在"结构跳跃"阶段带来社会福利的增加;而有利于打破污染型完全分工结构的锁定效应,推动经济结构升级至清洁型完全分工结构。文章关于环境政策激励清洁技术偏向的理论创新,对于当下的中国经济转型,特别是从污染技术的分工结构转向清洁技术主导的分工结构具有现实的指导意义。

This paper constructs a neoclassical economics model which using the intermediate energy （includes dirty energy and clean energy） to doing roundabout production of the final product, studying the microscopic mechanism and evolution trend of the effect of carbon - tax environmental regulation （pollution charges and subsidies to reduce emissions） on the tendency of clean energy. The study indicates： Government make the market incentive environmental regulation which is helpful for breaking the lock effect of dirty type division structure, promoting the economic structure switch to the clean type division structure, and sharing fixed learning cost of the development of clean energy and improving the efficiency of its trading. This paper construct a new theoretical model for the study of the effect of environmental policy on the innovation of clean energy, which has the practical guiding significance for analyzing China＇s economic transformation which is urgent to switch to the clean type division structure from the polluting division structure.
