碳交易是个很有趣的事情,最可爱的地方是它用市场化的思路去解决一个很复杂的社会问题,极具创新性。尽管碳交易是早些年就出现的事情,而且能否持续尚且存疑,但我们认真来剖析这样一个典型案例,对于当下积重难返的中国环境问题而言,有很大现实意义。碳交易的理论支撑源自著名的科斯定理。科斯定理从理论上解决了一个产权和交易费用的关系问题。具体来说,在碳交易问题上,碳的排放被设定为一种可估价、可交易的产权,于是这种环境问题就有了市场化解决的基础,这是一个很重要的 Carbon trading is a very interesting thing, the most lovely place is its market-oriented ideas to solve a very complex social issues, very innovative. Although carbon trading is a phenomenon that has occurred in the early years and whether it can be sustained and dubious, it is of great realistic significance for us to analyze such a typical case seriously for the current grave environmental problems in China. The theoretical support for carbon trading comes from the well-known Coase Theorem. Coase theorem solves the problem of the relationship between property rights and transaction costs theoretically. Specifically, on the issue of carbon trading, carbon emissions are set as an appreciable, tradable property, so that environmental issues have the basis for a market-based solution and it is important
