摘要
为探究绿色农业发展机制的演进,基于前景理论构建了不完全理性的政府、农户和消费者三方演化博弈模型,数值仿真三方的策略选择及演化过程,结合制度和偏好演化理论探讨了最优演化稳定状态的达成条件。研究发现:为达到有利于绿色农业发展的均衡,需要打破原有制度演化,构建与绿色生产、绿色消费相适应的制度环境。该过程的实现需要政府作为"创新者"率先偏离既定规则并带动其他博弈方取得更高收益。政府可从物质、信念、价值和心智模式角度改变农户和消费者的偏好演进,以最大化绿色农业发展的效益,具体包括:1)制定补贴政策和奖励机制;2)扶持绿色生产龙头企业、生产示范区等典型范例;3)制定有效的农业生态净化措施及检测标准;4)制定有公信力的绿色农产品标准,为消费者提供有力的甄别信号;5)通过知识宣讲、自然教育、农旅文化等手段提高公众对绿色农业的整体认知,推动全社会形成绿色生产和消费的文明风尚。
To explore the evolution of the development mechanism of green agriculture,a three-party(government,farmers and consumers)evolutionary game model was constructed based on the prospect theory.The strategy selection and evolution process of the three parties were simulated.The results show that:In order to achieve the development of green agriculture,it is necessary to break the evolution of the original system and construct a new system environment suitable for green production and green consumption.The government can change the evolution of farmers’ and consumers’ preferences from the perspectives of material,belief,value and mental model to maximize the benefits of green agriculture development:1)by formulating subsidy policies and incentive mechanisms,2)supporting green production leading enterprises,production demonstration areas and other typical examples,3)developing effective agricultural ecological purification measures and testing standards,4)formulating credible standards for green agricultural products to provide consumers with powerful screening signals,5)improving the public’s overall understanding of green agriculture through knowledge dissemination,natural education,agriculture and tourism culture and other means and promoting the civilized fashion of green behaviors in the whole society.
