基于供应链竞争的技术创新价值与溢出效应

Technological innovation value and spillover effect based on supply chain competition

基于两条竞争性供应链,分别建立了均采用传统技术或技术创新的对称模型,以及一个采用传统技术,另一个采用技术创新的混合模型.研究了竞争环境下溢出效应对于技术创新选择的影响.结果表明,制造商的技术创新选择不仅依赖于技术溢出水平和产品间的竞争强度,还与投资成本系数相关,但投资成本系数只起到了催化剂的作用.此外,无论对方供应链采用何种加工技术,或者产品竞争强度如何改变,只要上游制造商进行技术创新,其下游零售商的利润就会增加.

This paper investigates the impact of spillover effects on the innovation choice of manufactures with competing supply chains. A symmetry model is established, in which both supply chains choose traditional technology or innovation; and a mixed model is set up, in which two supply chains choose different production strategies respectively. The result shows that the manufacturer＇s innovation choice is affected by the intensity of competition, spiUover effect and investment cost coefficient, but the investment cost coefficient only acts as a catalyst. Furthermore, once the manufacturer chooses technological innovation, his retailer can get more profits than before.
