Research On The Boundary Of Enterprises Innovation Ecosystem Based On Complex Network

Under the background of innovation-driven development,the countary pays more and more attention to the development of innovation.The growth of corporate economic profits is also increasingly dependent on the sustained and healthy development of innovation.However,a variety of problems will be encountered in the innovation of enterprises,such as excessive innovation investment in the early stage,the unknown results of innovation,and the low return on innovation in the later period.In order to achieve the goal of reducing innovation investment in the early stage,enterprises begin to choose innovation cooperation with other enterprises.A network organization of multi enterprise cooperation innovation is formed on this basis.So the innovation ecosystem has come into being.In recent years,scholars and industry researchers at home and abroad have carried out a lot of exploration on the connotation,structure,evolution,evaluation and governance of innovation ecosystem from the perspective of macro,meso and micro.However the research on the boundary of innovation ecosystem is rarely involved,especially the innovation ecosystem under the micro scale.The boundary of innovation ecosystem plays an important role in realizing the sustainable development of the innovative ecosystem.The research on the boundary of innovation ecosystem provides detailed and accurate policy support for the enterprise managers and the formulation and implementation of innovative production schemes.In order to study the boundaries of innovative ecosystem,first of all,this paper studies the three innovative ecosystems in realities: letv innovation ecosystem,apple innovation ecosystem and mi innovation ecosystem.At the same time we analyse and summarize the characteristics of the three innovative ecosystem network structures.Secondly we selecte two indicators(network centrality and network adaptability)to divide the innovation ecosystem into three types: non-core innovation ecosystem,single-core innovation ecosystem and multi-core innovation ecosystem based on the above case analysis.Then the three types of innovation ecosystems are compared and coupled with the basic models of the three complex networks.A model of an innovative ecosystem based on complex networks is built.The five related statistical indicators of complex networks,namely marginal innovation revenue,degree and degree distribution,clustering coefficients,average path length and network efficiency are used to study the boundaries of the innovation ecosystem.Finally,we use MATLAB to simulate the three types of innovative ecosystem models: NCIE-ER model,SCIE-BA model and MCIE-LW model.We statistically analyze the related boundary indicators of these three types of innovative ecosystem models and obtained that innovation ecosystem boundary related conclusions.Results show that: Firstly,the innovation ecosystem have boundary,but the boundary of the innovation ecosystem cannot be expanded indefinitely.Secondly,if the knowledge spillover rate is different,the boundary of the innovation ecosystem will be different.Thirdly,different types of innovation ecosystems have different boundaries for innovation ecosystems.
