环保政策对我国碳排放权交易价格的影响研究——以湖北、广东和深圳碳排放权交易试点为例

The Impact of Environmental Protection Policies on Chinese Carbon Emission Trading Prices:A Case Study of Hubei,Guangdong and Shenzhen

以湖北、广东和深圳3个碳排放权交易试点为研究对象,运用事件研究法实证研究了环保政策对我国碳排放权交易价格的影响。结果表明:环保政策对湖北和广东碳排放权交易试点的碳排放权价格有明显影响,对深圳碳排放权交易试点的碳排放权价格无明显影响,这说明环保政策对不同碳市场的碳排放权价格影响存在差异。这可能是因为湖北、广东和深圳三个碳市场的行业覆盖范围和政策法规体系存在着较大差异。因此要扩大碳排放权试点的行业覆盖范围,建立以市场为主导的碳金融机制。

This paper mainly focused on the impact of environmental protection policies on China＇s carbon emission trading prices in the case of Hubei Province,Guangdong Province and Shenzhen City based on the Event Study Method. The results showed that environmental protection policies had an obvious effects on carbon emission trading prices in Hubei Province and Guangdong Province,while little effects on Shenzhen at there remained a difference between the impacts of environmental protection emission trading prices in different trials. One possible reason was that the scope of tent of policies were different. Consequently, our suggestion is to widen the scope of n emission rights trading trials and build a market oriented carbon financial mechanism.
