市场导向机制下绿色技术创新演化博弈研究

Evolutionary Game Study of Green Technology Innovation under Market Oriented Mechanism Considering the Additional Utility of Consumers to Green Products

针对市场导向绿色技术创新实践中存在企业绿色技术研发不足、政府干预偏差、市场需求不振等问题,引入绿色产品的额外效用以及消费者对绿色产品额外效用的反应度,在有限理性和完全竞争市场假设条件下,构建了企业、消费者与政府三主体演化博弈模型,得到不同绿色产品额外效用反应度下企业、消费者与政府的演化稳定策略,探索了市场导向机制下三方决策主体的演化路径和规律。通过仿真分析研究影响三主体最终策略选择的主要因素,并对主要变量进行了敏感性分析。研究表明,任意一方的策略选择都会影响到其他两主体的策略选择;当消费者是价格敏感型且满足一定条件时,存在(0,0,1)与(1,1,0)两种稳定策略;当消费者是环境敏感型且满足一定条件时,存在(1,1,0)稳定策略。最后,据此提出相关政策建议。

Aiming at the problems existing in the practice of market-oriented green technology innovation,such as insufficient research and development of green technology by enterprises,biased government intervention and uninspired market demand,based on this,this paper introduces the additional utility of green products and the response degree of consumers to the additional utility of green products.Under the assumptions of finite rationality and perfectly competitive market,the evolutionary game model of enterprises,consumers and government is constructed to obtain the evolutionary stability strategies(ESS)of game subjects(enterprises,consumers and the government)under different degrees of response to the additional utility of green products,and to explore the evolutionary paths and rules of the tripartite decision-making subjects under the market-oriented mechanism.Furthermore,the main factors influencing the final strategy selection of the three subjects are investigated by simulation analysis,and the sensitivity analysis of the main variables is carried out.The research shows that the strategy choice of either party will affect the strategy choice of the other two subjects;When consumers are price-sensitive and certain conditions are met,there are two ESS:(0,0,1)and(1,1,0).When consumers are environment-sensitive and certain conditions are met,an ESS:(1,1,0)exists.Accordingly,relevant policy recommendations are put forward.
