网络关系强度、技术多元化与企业产品创新战略

在模块化创新网络中，核心企业通过界面规则重组知识模块，分别与模块供应商、系统集成商在纵向和横向上进行知识整合以实现技术创新。以2001-2014年中国汽车产业108家整车制造企业为研究样本，探讨模块化创新网络关系强度对企业渐进式产品创新和突破式产品创新的影响，并分析技术多元化的调节作用。结果发现：模块供应商关系强度越大越有利于渐进式产品创新；系统集成商关系强度越大越有利于突破式产品创新；技术多元化减弱了模块供应商关系强度对渐进式产品创新的促进作用，但增强了系统集成商关系强度对突破式产品创新的促进作用。

Network Tie Strength,Technological Diversification and Firms' Product Innovation Strategy

In the modular innovation network,core enterprises reorganize network knowledge modules through interface rules,and manage integration of knowledge with module suppliers and system integrator in vertical and horizontal directions.By taking the vehicle manufacturers of china's automobile industry from 2001 to 2014 as our research sample,we discuss the influence of modular innovation network tie strength on the incremental product innovation and radical product innovation,we also analyze the moderating effect of technological diversification.The research found that,tie strength with module suppliers plays a greater role in improving incremental product innovation,while tie strength with system integrator plays a greater role in improving radical product innovation.At the same time,technological diversification weakens the positive relationship between module supplier tie strength and incremental product innovation,while enhance the positive relationship between system integrator tie strength and radical product innovation.
