摘要
在排污权交易经济理论基础上,结合对现实企业差异性与决策机制分析,构建了基于异质主体的区域排污权交易系统计算实验平台,并对排污权交易系统效率以及许可证价格进行初步研究。结果表明,企业间差异性对系统效率有促进作用;在信息不完全市场中,许可证价格可以收敛,但高于理论均衡价格;由于企业行为偏差使得许可证价格对其自身有阻滞效应,单纯价格导向不能使市场完全有效,而企业差异性可对不完全信息带来的效率损失有补偿效应。研究也表明了对排污权交易系统进行异质性分析与建模的必要性。
According to economic basis of emissions trading,a heterogeneous agent-based computational experiment platform for regional emissions trading was established,by combining analyses of the diversities and decision-making mechanisms of companies in real world.Then pilot analyses were done on efficiency of emission trading and permit price.The experimental results showed that diversities of companies would advance system efficiency,market price converged above equilibrium price,and a retarding effect was on permit price through itself.Price-oriented trading strategy could not lead to effective collocation of permits,but diversities of companies would generate a countervailing effect on system efficiency.The requirement of heterogeneous modeling and analysis on emissions trading system was proofed thought experimental results.
