消费排放权交易对消费者选择行为的影响——源自实验经济学的证据

消费模式对碳排放具有重要影响,加强消费行为的引导和管制,构建低碳消费模式已经成为一个亟待突破的重大课题。为了将消费因素纳入减排框架,本文基于总量管制和交易机制(Cap-and-Trade Rules)构建了消费排放权交易理论模型,在此基础上运用规范的实验经济学方法分析了消费排放权交易的市场均衡问题,以及均衡状态下的消费者选择行为。通过实验研究发现,消费排放权的交易价格会收敛于理论竞争均衡价格,即临界碳价;消费排放权交易能够激励消费者选择低碳产品,有利于创造低碳需求,构建低碳消费模式。基于这些研究结论,文章给出启示性政策建议。

The Effects of Consumption Emissions Trading on Consumer’s Choice——Evidence from Experimental Economics

The consumption pattern has important implications on carbon emissions.Strengthening the guidance and control on consumption behavior,and building low-carbon consumption pattern have become a major task that should be solved urgently.To integrate the factor of consumption to the carbon reduction frame,this paper adopts standard methods of experimental economics to establish a theoretical model of consumption emission trading based on the cap and trade mechanism.Through experimental study,we found that the price of consumption emission trading converges to the competitive equilibrium price,which is the critical carbon price.Further,consumption emission trading can encourage consumers to choose green products,which can create low-carbon demand.Based on these findings,this paper gives revelatory policy suggestions.
