摘要/Abstract

摘要： 基于2个开展R&D活动的供应商和2个竞争制造商组成的链与链竞争模型，研究了技术溢出条件下供应链企业R&D投资策略与协同机制。研究结果表明，纵向R&D合作投资是供应链系统博弈的占优策略，此时供应链系统收益、R&D投资水平均高于不合作情况，并且适度的技术溢出有利于提高供应链企业创新热情。但对于供应链成员企业而言，在自利动机驱使下，仅在一个有限的R&D成本分担比例区间内做出的决策与供应链系统一致，只有在该区间对成员企业的利益进行协调才能实现R&D合作的协同性。为此设计了基于合作满意度的R&D成本分担机制，通过建立不对称NASH谈判模型较好地协调了合作双方的利益，促进了供应链R&D协同效应的实现。

Abstract: Technological innovation is an important way for a supply chain firm to gain competitive advantage. By using game theory, a model is presented for chain to chain competition with two suppliers engaged in R&D and two competing manufacturers. With this model, the competition equilibrium, R&D strategy and synergistic conditions of supply chains with technological spillovers are analyzed. Results show that vertical R&D cooperation is the dominant strategy of supply chains to bring higher equilibrium profit and R&D input level than those of firms without cooperation activities. It also shows that appropriate technological spillover can improve innovation enthusiasm of suppliers. However, suppliers and manufacturers select R&D cooperation only in a finite R&D cost allocation range due to their self-serving motives. The R&D cost should be allocated in the interval such that the stability and synergy effect of R&D cooperation can be reached. Thus, cost allocation mechanisms are designed based on cooperation satisfaction to realize the synergy effect of vertical R&D cooperation, with which the benefits of both partners can be better coordinated by NASH negotiation model.

Key words: chain to chain competition, technological spillovers, vertical R&D cooperation, game theory
