创新模式的合理选择关系到企业未来的生存与发展。基于供应链视角，利用演化博弈理论对下游企业的创新模式选择进行了分析。在此基础上探讨了R＆D因素与下游企业创新模式选择的关系及其对上游企业期望收益的影响。结果表明：吸收能力、内生溢出对上下游企业R＆D投入与期望收益均具有正向作用，并与下游企业选择颠覆性创新模式的可能性正相关：而R＆D投入与下游企业选择渐进性创新模式的可能性正相关：下游企业选择颠覆性创新模式的可能性对上游企业R＆D投入与期望收益具有负向作用。根据这些结论。最后给出了上下游企业的R＆D策略。%Rational selection on innovation mode relates to the survival and development of enterprises in the future. Based on supply chain perspective, the downstream enterprises innovation mode selection is analyzed through evolutionary game theory. Based on this, effects of R&D factors on downstream enterprise innovation mode selection and expected profit of upstream enterprise are discussed. The results show that: absorptive capacity, endogenous spillovers have positive effects on the upstream and downstream enterprises R&D input and expected profit, and have positive relationship with possibilities of downstream enterprises to select the disruptive innovation mode; while R&D input has positive relationship with possibility of downstream enterprises to select incremental innovation mode; the possibility of downstream enterprises to select disruptive innovation mode has negative effect on upstream enterprise's R&D investment and expected profit. Based on these results, R&D strategies for upstream and downstream enterprises are proposed at last.
