| The Chinese economy is enjoying its fast development,enterprises as the innovation subject of high-quality development are also facing more complex and intense challenges.At the same time,in the market under the background of rapid change and the complexity of innovation,if the enterprise alone has its own knowledge,technology and other resources in the organization of the high cost of innovation,not only can lead to fragmentation "information island" and innovation achievements,also can make enterprise is difficult to adapt to changing market demand and high pressure of competition.Therefore,the discussion on the relationship between the structural characteristics of innovation ecological network and the performance of collaborative innovation of enterprises is not only conducive to improving the enthusiasm and initiative of enterprises to carry out collaborative innovation by using innovation ecological network,but also has important practical significance for innovation subjects to fully and effectively carry out collaborative innovation according to the structural characteristics of innovation ecological network.Firstly,based on the research of this paper,the research status of the structural characteristics of innovation ecological network,corporate collaborative innovation performance,knowledge flow intensity,knowledge inertia and regional niche suitability is sorted out,research gaps are found,concepts of relevant variables are defined and relevant theories are summarized.Secondly,the relationship among structural characteristics of innovation ecological network,strength of knowledge flow,knowledge inertia and regional niche suitability was analyzed,and relevant research hypotheses were proposed respectively to build a theoretical model of the relationship between structural characteristics of innovation ecological network and corporate collaborative innovation performance.Then,SPSS25.0 and AMOS24.0 software were used for empirical analysis of 589 valid sample data,and Python was used to rank the niche suitability of each region.The grouping regression method was used to verify the regional difference effect of niche suitability on the relationship between the structural characteristics of innovation ecological network and the collaborative innovation performance of enterprises.Finally,according to empirical research results and the actual situation of innovation subjects in China’s innovation ecological network,countermeasures and suggestions are put forward from the structural characteristics of innovation ecological network,strength of knowledge flow,knowledge inertia and regional differences caused by regional niche suitability. |
