摘　　要：纵向合作创新是制造业企业常用的技术创新模式。本文利用三级供应链模型对Samiran Banerjee andPing Lin(2001)的二级纵向合作创新模型进行改进,研究了在M个上游企业、1个中游企业和N个下游企业构成的三级供应链中,中游企业的技术研发策略对技术研发效果和整个产业链体系的利润函数的影响。研究结果表明:相对于未创新的初始状态,中游企业的研发活动可以增加供应链上各级企业的利润;中游企业的独立研发策略会产生溢出效应,使上、下游企业利润增加;相对于独立研发策略,中游企业的合作研发策略可以获得更大的研发效果,更高的中游企业和全产业链利润。Advancing information technology is shortening product life cycle and the lead time to market for new products.To overcome limited RD budgets and resources,an enterprise often resorts to building an RD alliance with other enterprises.Cooperative RD alliances can help increase the speed of new product development and reduce investment risks.The industrial economics literature shows that RD alliances can be formed via vertical cooperation or horizontal cooperation.Empirical studies show that vertical RD alliances are more widely used and effective than horizontal RD alliances in helping enterprises improve their innovation capability.However,the theoretical research on horizontal RD alliances is very limited.There is a growing need for researchers to understand the potential effect of horizontal RD alliances on RD profits and innovation capability.This paper proposes a three-level industry chain system based on Banerjee and Ling＇s two-level vertical cooperation innovation model.The industry chain system consists of M upstream enterprises,1 midstream enterprise,and N downstream enterprises.The midstream enterprise plays a leading role in the industry chain by sourcing materials from upstream enterprises,processing the raw materials,and selling the works-in-progress to downstream enterprises.The downstream enterprises convert the works-in-progress into final products for end customers.Therefore,the midstream enterprise can play the central role of forming a vertical RD alliance with upstream and downstream enterprises.All enterprises in the industry chain can share both costs and profits,and improve their innovation capability.The midstream enterprise can adopt three strategies to help form the vertical RD alliance： non-RD,independent RD,and cooperative RD.Depending on the strategy adopted by the midstream enterprise,our model calculates the outputs and profits for each form of enterprise in the supply chain： upstream,midstream and downstream enterprises.The main conclusions from this paper are as follows.（1�
