运用汽车生产商知识对不同类型供应商技术创新的促进作用

基于通过交叉供应商在知识创造能力和与生产商技术相似度两个维度的异质性,将供应商分为4类。采用专利数构建计量指标,探索了不同类型的供应商在技术创新中运用生产商知识的效果。非参数检验与负二项回归结果证明了供应商异质性的存在。研究结果还显示:能力弱的供应商运用生产商知识能获得更好的创新成果--无论它们与生产商技术的相似度高低与否;能力强的供应商不能通过运用生产商知识获得高水平的创新成果。

Effects of Using Automakers' Knowledge on Different Kinds of Suppliers' Technological Innovation

Two dimensions of heterogeneity of supplier are focused on the supplier's creation capability and the supplier's technological proximity to automakers.A classification is constructed by crossing these two dimensions,and 4 types of suppliers are distinguished.An empirical test is constructed based on patent data to construct variables and to explore the effect of using automakers' knowledge in different type suppliers' innovations.Test results of non parametric estimation and negative binomial regression verify that there are distinct effects of using automakers' knowledge among different types of suppliers.Furthermore,it is revealed that suppliers with weak capability may be improved in their innovation by using automakers' knowledge,regardless of their technological proximity to automakers.But the suppliers with strong capability may have less from the use of automakers' knowledge.
