The Research On The Influence Of Enterprise Knowledge Base On Dual Innovation

In the era of knowledge-based economy,a company's core competitive advantage lies in its ability to create,accumulate and use knowledge,through which the company can achieve innovation.Heterogeneous performance exists widely between enterprises,especially the innovation performance differences,which is largely due to differences in their ability to create new knowledge.Therefore,from the knowledge-based view of the firm,a firm is essentially a collection of various types of knowledge elements,or a knowledge base.Innovation comes from the recombination of existing knowledge elements,and the existing knowledge base of a company not only reflects the ways companies take use of knowledge,but may also reveal the future direction of innovation.The relationship between knowledge elements in the knowledge base has not yet fully analyzed,and the characteristic of firm knowledge base is not comprehensive in prior research.In this paper,we differentiate the basic characteristics of knowledge into the knowledge structure dimension and knowledge relational dimension on the basis of existing research.Drawing on existing research,we distinguished knowledge structure dimension into knowledge breadth and knowledge depth while knowledge relational dimension into knowledge complementarity and knowledge substitutability.And we will study their impact on firm dual innovation.The paper will take use of International Patent Classification(IPC)to measure the breadth and depth of corporate knowledge,and then build knowledge elements co-occurrence matrix based on the IPC system.We characterize a company's knowledge base as knowledge breadth and depth from knowledge stock view and knowledge complementarity and knowledge substitutability from relational properties,and then we will carry out an empirical research about the impact of enterprise knowledge base characteristic on its dual innovation.In order to test our hypothesis,we gather 89 listed companies' data from 2000-2013 in China auto industry as our empirical sample,and apply descriptive statistical analysis,correlation analysis,and negative binomial regression model as our empirical analysis tools.The empirical results show that:the knowledge breadth has positive effect on a company's dual innovation,while knowledge depth' impact on dual innovation is not significant;enterprise knowledge substitutability has inverted U-shaped effect on exploratory innovation while a positive impact on exploitative innovation,knowledge complementarity's impact on dual innovation is not significant.Our conclusions are meaningful to understand the role of corporate knowledge base in its innovative activities comprehensively and could help the company enhance its capacity of enterprise knowledge management.
