Cluster Evolution And Performance Analysis From The Perspective Of Innovation Network

Since the concept of "mass entrepreneurship and innovation" was put forward,enterprises in various fields have continuously increased R&D investment,improved their innovation capacity,explored new ways of innovation,and realized the transformation from being the main producer to the main innovator.At the same time,the innovation environment of enterprises is increasingly dynamic and complex,and the innovation market and innovation elements are developing in a diversified way.All these urgently require innovation subjects to choose targeted resources according to their actual conditions and improve their professional ability.In addition,the trend of enterprise competition is gradually evolving from individual enterprise competition to regional industry competition.In "to grasp the new opportunities,stimulating new kinetic energy",in the process of Nanjing new and high technology industries developing rapidly,enterprises,institutions of higher learning,scientific research institutes,government,financial institutions and other innovative main body communication and collaboration,contributed to the generation of innovation network,innovation elements such as manpower,technology,knowledge and capital full flow in the network,continuous reaction in innovation enterprise.In this background,to want to optimize the space layout of the Nanjing new and high technology industries,improve the level of the development of hightech industries,studies the Nanjing high-tech industrial cluster innovation network space resource distribution,the difference of spatial development,specialization degree and the factors that affect cluster enterprise innovation,summarizes the industrial cluster and the evolution of the law will be a practical path.Based on the above background,this paper selects Nanjing high-tech industrial cluster as the research object,and firstly sorts out the open innovation theory,knowledge base theory,innovation network evolution theory and related researches.Then,based on the data of Nanjing enterprises and science and technology investment,the spatial distribution of innovation resources and industrial differences among different regions of Nanjing high-tech industry are analyzed by using location quotient and GeoDa spatial autocorrelation method.Secondly,a complex network evolution model considering adaptive entry and maladaptive exit of enterprises is constructed to analyze the network evolution law of the dynamic change of innovation subjects.Finally,this paper focuses on the mechanism of network embedding on enterprise innovation,and analyzes the mediating role of knowledge acquisition.In order to make the results more universal,two moderating variables,network power and knowledge integration,are introduced into the model.Under this theoretical hypothesis model,enterprises in high-tech industrial clusters were selected as the research objects,and 306 valid data were collected through questionnaires.SPSS and AMOS were used to conduct sample normality test,reliability and validity analysis,common method deviation test and regression analysis.Finally,based on the literature and empirical research results,the paper provides countermeasures and suggestions for the operation of Nanjing high-tech industrial cluster innovation network,promoting industrial innovation and promoting industrial development.
