碳排放权交易制度会促进企业绿色创新吗?

Does Carbon Emission Trading Schemes stimulate Corporate Green Innovation?

碳排放权交易制度是中国首次将市场化机制引入碳减排工作的尝试,本文利用PSM-DID模型实证检验2013年实施的碳排放权交易制度试点政策对微观企业绿色创新的影响。研究发现,碳排放权交易制度显著降低了企业绿色创新,主要体现在绿色专利申请数量的减少上,并且相较于绿色实用新型专利,碳排放权交易制度对绿色发明专利的负面影响更大。进一步的分析结果表明,碳排放权交易制度对国有企业、位于低政府环保关注度地区以及碳排放权交易价格较低地区企业的绿色创新的负面作用更显著。说明在中国碳排放权配额发放宽松、成交价格低、碳排放权交易制度实施及监管力度尚不足的背景下,企业缺乏激励主动进行绿色创新。

the carbon emission trading schemes is China's first attempt to introduce a market-based mechanism into carbon reduction efforts.This paper uses a PSM-DID model to examine the impact of the carbon emission trading schemes pilots implemented in 2013 on firm-level green innovation.Our baseline findings show that the carbon emission trading schemes significantly reduce green innovation,this is mainly reflected in the decrease in the number of green pantent applications,and the trading scheme has a greater negative impact on the green inventive patents than green utility model patents.Additional analysis further shows that the effect is more salient for state-owned enterprises,firms located in areas of low government environmental concern,and firms in areas with low carbon emission rights trading prices.Our findings suggest that under the backdrop of loose allocation of carbon emission allowances,low trading prices,and inadequate implementation and supervision of the carbon emission trading scheme,firms lack incentives to actively engage in green innovation.
