纵向溢出效应供应链企业间的协同创新研究

The Collaborative Innovation in Supply Chain with Vertical Spillovers

由供应商、制造商和销售商组成的供应链,在具有纵向创新溢出效应的情况下,三方能否协同创新对供应链总收益、创新投入以及产品产量均有影响。研究结果表明,在三方协同创新情形下,供应链总收益、创新投入以及产品产量均大于三方非协同创新的情形。并且纵向溢出效应越大、创新系数越小,供应链总收益、创新投入以及产品产量越大,反之亦然。

In a supply chain composed of supplier, manufacturer and retailer, the decision making process involves threeparty＇s non-collaborative innovation and three- party＇s collaborative innovation in supply chain with vertical spillovers. The paper compares the total benefit of supply chain with investment innovation and output. The vertical spillovers of innovation and innovation coefficient have much impact on the total benefit of supply chain, investment innovation and output. The result shows that these parts are more in the state of three - party＇s collaborative innovation than them in the state of three - party＇s non - collaborative innovation. The increase when vertical spillovers of innovation increases or innovation coefficient decrease.
