科斯定理对排污权交易政策的理论贡献

排污权交易政策旨在通过建立一个有效的排污权体系,以激励容量资源的"所有者"更有效地使用环境容量,从而实现环境容量资源的高效率配置。其理论基础是科斯的"通过权利的清晰界定来获得资源配置的效率"的论断。首先,科斯使"交易费用"成为研究资源配置的组织形式和配置效率问题的有效工具。其次,对外部性问题的解决,科斯强调建立产权的重要性,并提出了"私有产权加价格机制"的解决方案。再次,科斯强调解决外部性问题时分析方法的改变,在设计和选择方案时,既要考虑制度变化带来的效果,也要考虑各种制度的运行成本和转换成本。

On the Contribution of Coase Theorem to Emission Trading

In view of the widely held misconceptions of emission trading in the academic and the practical arena, this paper points out that understanding of emission trading should be based on the whole framework of Coase Theorem. This paper makes a comprehensive analysis of the Key issues of Coase Theorem, including transaction cost, property right and criteria for policy instruments selection, etc. which will facilitate better understanding of the policy instruments of emission trading and help use it more efficiently in environmental problem solving.
