基于系统动力学的碳标签产品购买行为博弈分析

Game Theoretical Analysis on Purchase of Carbon Labelled Product Based on a System Dynaimcs

本文基于演化博弈构建了系统动力学模型,以考察产品价格及价格补贴对消费者群体选购碳标签产品的影响。结果表明碳标签产品价格对消费者的购买行为有显著影响。以牛奶产品为例,当其溢价超过0.3元时,会降低消费者对碳标签产品的购买意向。价格补贴对激励消费者选购碳标签产品的效果并不显著。基于研究结果,本文提出政策建议,为碳标签体系在我国的实施提供理论依据。

The study provides a system dynamics based on evolutionary game model to examine the impacts of price and price subsidy on consumers’ purchase of carbon labelled product. The result shows that the price has a significant influence on consumers’ purchasing behavior. By taking milk product as an example, the result further indicates that the price premium over 0.3 RMB will decrease the purchase intention of the consumers. The price subsidy is not sufficient to incentivize the purchase of carbon labelled product. It is expected that the study may provide insight into policy making on implementation of carbon labelling scheme in China.
