摘　　要：在绿色农产品供应链产销主体利益博弈中,产品低感知而高溢价利益回报特性引发的主体间信息不对称缺陷,是利益冲突及信任危机问题的根源。区块链信息透明化技术特征可弥补该缺陷,但主体对技术的采纳受多因素影响,使上链博弈决策存在不确定性。鉴于此,依托TOE框架分析主体上链决策影响因素,构建演化博弈模型并分析演化稳定策略,通过系统动力学仿真揭示影响因素间的内在联系及其对系统动态演化影响机理。结果表明:主体上链决策受对方初始上链概率及市场绿色度敏感程度正向影响,受价格敏感系数负向影响;绿色度敏感程度对主体上链策略演化速度有促进作用,但存在边际递减效应;绿色成本系数对产端主体上链策略演化速度有抑制作用。In the game of interests between production and sales entities in the green agricultural product supply chain,the information asymmetry defect caused by the low perception and high premium return characteristics of products is the root of interest conflicts and trust crises.Blockchain technology has the characteristic of information transparency,which can compensate for the information asymmetry defect.But the adoption of technology by the subject is influenced by multiple factors,resulting in uncertainty in the decision-making process of the on-chain game.In view of this,the study analyzes the influencing factors of the entities decision-making based on the TOE framework,constructs an evolutionary game model,analyzes the evolutionary stability strategy and reveals the internal connections between the influencing factors and their impact mechanism on the dynamic evolution of the system through system dynamics simulation.The results indicate that the entities decisions of on-chain are positively influenced by the opponent s initial probability of on-chain and the sensitivity of market greenness,and negatively influenced by the price sensitivity coefficient;the sensitivity of greenness has a promoting effect on the evolution speed of the entities on-chain strategies,but with diminishing marginal effect;the green cost coefficient has a restraining effect on the evolution speed of the on-chain strategy of the production entities.
