排污权交易的经济分析

An Economic Analysis on Emissions Trading

排污权交易是 照科斯定理而制定的基于市场机制的行之有效的污染控制手段。实行排污权交易的结果是污染的治理主要由边际治理成本较低的企业来完成,从而优化了资源配置,有利于社会总产值的提高。排污权交易便于政府进行污染物的总量控制,有助于推动企业进行污染控制技术的革新,实施清洁生产,也有利于环境保护与经济的协调发展,应尽快在我国推广。

Tradeable emissions permits or emissions trading established on the basis of Coase Theorem is a effective market - based pollution control approach. One of the outcomes of emissions trading is that the abatements of pollution are mainly completed by the firms possessing lower marginal cost of abatement and therefore it optimizes the resource allocation. Compared with the command - and - control regulation, emissions trading approach is much more convenient for the government to meet its targets of environmental level, and provides strong incentives for the firms to innovate their pollution control technology or adopt 'clean production' technology, also is helpful to harmonize environmental protection and economical development. It is suggested that emissions trading should be promoted as soon as possible.
