网络位置、知识基础对企业新产品开发绩效的影响

The Impacts of Network Positions,Knowledge Base on Firms’ New Product Development Performance

本研究利用我国汽车产业1998-2013年的联合申请专利构建协作研发网络,研究了网络位置对企业新产品开发绩效的影响,并分析了知识基础在网络位置与新产品开发绩效之间的中介作用。实证分析表明:企业网络中心度和结构洞对新产品开发绩效均具有明显促进作用;知识宽度和知识深度与新产品开发绩效之间均存在显著的正向关系;知识宽度和知识深度在网络中心度与新产品开发绩效之间具有部分中介作用,而知识宽度在结构洞与新产品开发绩效之间存在完全中介作用。

In this study,we construct collaborative R&D network based on joint patent data of China’s automobile industry from 1998 to2013. We discuss the impacts of network positions on firms’ new product development performance,and analyze the mediating effect of knowledge base on the relationship between network positions and the influence on the new product development performance. We find that network centralization and structural holes have a positive relationship with a firms’ new product development performance. In addition,there is a positive relationship between knowledge breadth and knowledge depth and a firms’ new product development performance. Also we find a partially mediating effect of knowledge breadth and knowledge depth on the relationship between network centralization and the new product development performance,and a fully mediating effect of knowledge breadth on the relationship between structural holes and the new product development performance.
