绿色食品企业技术创新合作策略选择的演化博弈分析与仿真

Evolutionary game analysis and simulation of the choice of technological innovation cooperation strategies of green food enterprises

为探究绿色食品企业技术创新合作策略的影响因素,研究基于演化博弈理论,构造支付矩阵及演化博弈模型,并运用Matlab软件对演化模型进行数值仿真试验,对绿色食品技术合作创新策略选择进行演化博弈分析。结果表明:绿色食品企业合作策略受双方共同进行“开放式创新”策略的成本(I)和产出(R)、一方独自进行“开放式创新”策略的成本(C)和产出(E)及双方合作效益分配比例(k)的影响。在其他参数不变的情况下,I越高,双方选择“开放式创新,开放式创新”合作模式的可能性越高;I越低,双方选择“封闭式创新,封闭式创新”合作模式的可能性越高。R越高,双方选择“封闭式创新,封闭式创新”合作模式的可能性越高;R越低,双方选择“开放式创新,开放式创新”合作模式的可能性越高。C越高,企业选择“封闭式创新”策略的可能性越高;C越低,企业选择“开放式创新”策略的可能性越高。E越高,企业选择“开放式创新”策略的可能性越高;E越低,企业选择“封闭式创新”策略的可能性越高。当k取值为0.5时,双方选择“开放式创新,开放式创新”合作模式的可能性最高。鉴于此,对绿色食品企业提出关注行业技术创新现状,发挥龙头企业带头作用;积极运用外部资源,灵活与相关机构进行合作;合理进行要素投入评估与效益分配,提高合作积极性的对策建议。

In order to study the influencing factors of green food enterprises’ technological innovation cooperation strategy, based on evolutionary game theory, this study constructed payment matrix and evolutionary game model;used Matlab software to conduct numerical simulation test on the evolutionary model, and carried out evolutionary game analysis on the choice of green food technology cooperation innovation strategy. The results showed that the cooperation strategy of green food enterprises was affected by the cost(I) and output(R) of the open innovation strategy carried out by both parties, the cost(C) and output(E) of the open innovation strategy used by one party alone, and the proportion of the cooperation benefit(K). When other parameters remained unchanged, the higher I was, the higher the possibility of “open innovation, open innovation” cooperation mode was. The lower I was, the more possible that both parties would choose the cooperation mode of “closed innovation, closed innovation”. The higher R was, the more likely the two parties would choose the cooperation mode of “closed innovation, closed innovation”. The lower R was, the more likely the two parties would choose the cooperation mode of “open innovation, open innovation”. The higher C was, the more possible that the enterprise would choose the “closed innovation” strategy. The lower C was, the more likely an enterprise would choose the “open innovation” strategy. The higher E was, the more likely the enterprise would choose the “open innovation” strategy. The lower E was, the higher the possibility that the enterprise would choose the “closed innovation” strategy. When k was 0.5, both parties were most likely to choose the cooperation mode of “open innovation, open innovation”. In view of this, the green food enterprises were proposed to pay attention to the status quo of technological innovation industry and play a leading role;actively utilize external resources and cooperate with related institutions flexibly;reasonably evaluate input factors and benefit distribution, improve the initiative of cooperation.
