我国试点碳市场运行效率评价研究

Study on the Operation Efficiency Evaluation of Pilot Carbon Trading Markets in China

摘要:

基于我国7个碳排放权交易试点(ETS)2014~2015年面板数据,设计了加权碳价格、价格稳定性、交易活跃度、配额松紧度、市场参与度等评价指标,继而构建了试点碳市场运行效率DEA评价模型并给出改进方案。结果表明,深圳、湖北和天津碳市场为DEA有效,上海、北京、广东和重庆碳市场效率值依次递减,且处于规模递增阶段；深圳碳价格水平及其稳定性最高,广东、湖北交易活跃度增长最快；试点碳市场普遍存在配额总量过剩、控排企业参与度偏低等运行“短板”。

Abstract:

Based on panel data of seven pilot carbon trading markets(ETS) in China from 2014 to 2015, This paper designed a series of evaluation indexes such as weighted carbon price, price stability, trading activity, degree of carbon quota tightness and market participation. Then we built a DEA model to evaluate the operation efficiency of pilot carbon markets and provided an improved scheme. The results show that Shenzhen, Hubei and Tianjin ETS are DEA efficiency; The efficiency value of Shanghai, Beijing, Guangdong and Chongqing ETS are decreasing and meanwhile in the stage of increasing scale; Shenzhen ETS"s carbon price level and its price stability are the highest, Guangdong and Hubei ETS are the fastest growing of trading activity; Pilot carbon markets are common facing "short board" such as total carbon quota surplus, low market participation of enterprises that under carbon emission controlled.
