排污权交易机制在中国能否实现波特效应?

Can Emissions Trading Scheme Achieve the Porter Effect in China?

"既要金山银山,也要绿水青山",意味着中国在"新改革"中既要保持经济发展,更要环境改善,达到经济与环境的双赢,实现波特效应。合理而严格的环境政策推动企业技术创新实现经济与环境双赢,是波特假说的核心思想。本文在控制地区环境规制等重要解释变量下,试图回答SO_2排污权交易试点在中国是否激发波特效应。研究发现:尽管排污权交易机制在一定程度上缓解了现阶段SO_2排污权配置的严重无效率问题,但从现实和潜在两个角度观察,SO_2排放权交易试点政策在我国均未能产生波特效应。究其原因,低效运转的市场还不足以支撑排污权交易机制的"完美"运行,整体较弱的环境规制也不能与排污权交易机制的"完美"运行相匹配。依法加强市场建设和环境规制,形成与之配套的市场和政府内外"双引擎",是实现波特效应的必要条件。

＂We need golden and silver hill as well as clean water and green mountains＂. It means China should achieve the Porter effect which states a win-win development of economic and environment in the ＂New Reforms＂. It is the major prerequisite for Porter Hypothesis to promote technology innovation by reasonable and strict environmental policy. This paper evaluates the Porter effect of China＇s industrial SO2 emissions trading pilot scheme （SETPS） with environmental regulation and other conditions remaining constant. Our findings are that SETPS could play a certain role in relieving the serious configuration inefficiency problem of emission rights, but it failed to achieve the Porter effect in both the short and long term. An inefficient market and a weak environmental regulation hadn＇t matched a ＂perfect＂ SETPS. Efficient market construction and strong environmental regulation to form inside and outside ＂Double Engines＂ of market and government are necessary conditions.
