【摘要】：基于产品质量提高型创新视角,将技术溢出水平、产品水平差异与垂直质量差异等因素一起纳入分析框架,构建三阶段动态博弈模型,探讨了不同研发模式下企业研发投入决策和政府最优补贴政策。结果显示:政府补贴有利于提高企业研发投入的积极性与社会福利水平,不会产生"挤出效应";技术溢出水平与产品差异化程度均对不同研发模式下政府最优补贴强度的影响有较大差异;在政府最优补贴强度下,研发竞争与研发合作模式中企业的研发投入、产品质量及社会福利水平是相同的,企业倾向于选择利润最大化的研发模式。算例分析结果进一步验证了模型的有效性。为此,企业自身应加强研发投入,提高产品质量竞争力,而政府则应针对不同的研发创新模式与产业周期特征制定合理的补贴强度区间,同时应加强企业补贴资格审查制度建设,提高创新激励效率。
[Abstract]:Based on the innovation perspective of product quality improvement, the factors such as technology spillover level, product level difference and vertical quality difference are brought into the analysis framework together, and a three-stage dynamic game model is constructed. This paper discusses the decision of R & D investment and the optimal subsidy policy of government under different R & D modes. The results show that government subsidy is beneficial to improve the enthusiasm of R & D investment and the level of social welfare. There is no "crowding out effect"; the level of technology spillover and the degree of product differentiation have great differences on the intensity of the government's optimal subsidy under different R & D modes; in the case of the government's optimal subsidy intensity, The R & D investment, product quality and social welfare level in R & D competition and R & D cooperation mode are the same. Enterprises tend to choose the most profitable R & D model. The results of the example analysis further verify the validity of the model. Enterprises should strengthen their own R & D investment to improve the competitiveness of product quality, and the government should establish a reasonable subsidy intensity range according to different R & D innovation models and industry cycle characteristics, and strengthen the construction of enterprise subsidy qualification examination system. Improve the efficiency of innovation incentive.
