结局不确定条件下关键共性技术合作创新策略研究

Research on Key Common Technology Cooperative Innovation Strategies under Uncertain Outcomes

采用改进的Stackelberg方法,考虑技术溢出和产品差异性的影响,构建包含市场竞争和研发投入的关键共性技术博弈模型,分析创新结局不确定性对企业合作策略的影响,探讨企业如何动态选择合作创新策略以应对这种不确定性。研究结果表明,不确定性较高时,企业倾向于选择资源合作策略以获取更多外部支持;不确定性较低时,企业倾向于选择市场合作策略以获得更多的创新收益;技术溢出程度和产品差异程度显著影响关键共性技术合作创新策略,加大产品差异性能有效降低技术溢出给创新企业带来的负面效应。

Using a modified Stackelberg game approach,a game model of key common technologies including market competition and R&D investment is constructed,taking into account the effects of technology spillover and product differentiation.The impact of innovation outcome uncertainty on firms'cooperation strategies is analyzed,and how firms dynamically choose cooperation innovation strategies to cope with this uncertainty is explored.The results show that:when uncertainty is high,firms tend to choose resource cooperation strategy to obtain more external support;when uncertainty is low,firms tend to choose market cooperation strategy to obtain more innovation benefits;the degree of technology spillover and the degree of product differentiation significantly affect the cooperative innovation strategy of key common technologies,and increasing product differentiation can effectively reduce the negative effects of technology spillover on innovative firms.
