Venture Capital Network Community Ties Changing And Impact On Structure Evolution

Venture capital,as an important part of China's economic restructuring and financial innovation system,is the main force driving the development of our country's high-tech industry and small and medium-sized entrepreneurial enterprises,and is of great significance to the realization of my country's innovation-driven development strategy.With the increasingly fierce competition in the venture capital industry,the role of venture capital network development has become more and more significant.The venture capital network community,as an internal law of the development of venture capital networks,not only shows the phenomenon of agglomeration of venture capital firms in network space,but also a kind of sub-network structure which is based on mutual preference of venture capital firms between global network and ego network.There are a few researches on the venture capital network community,most of which are focused on community detection and the impact of community on performance from the static perspective,but there is a lack of research on the evolution of the venture capital network community and ties changing from the dynamic perspective.With the rapid development of the venture capital industry,the corresponding theoretical research is slightly lagging behind.unable to systematically explore the internal laws of the venture capital network community,and unable to provide theoretical guidance for venture capital firms to rely on community development.This dissertation attempts to explore the influencing factors of ties changing of venture capital network community and build the overall framework of the research on the ties changing of the venture capital network community,aiming to explore the mechanism of community ties changing and the impact of ties changing on structural evolution,and then provide theoretical guidance for the network development of the venture capital industry.Firstly,this dissertation clarifies the phenomenon of community in venture capital network and analyzes'the types and characteristics of community.Secondly,this dissertation explores the influencing factors of the venture capital network community ties changing,and constructs the overall research framework via the grounded theory.Thirdly,explore the impact of influencing factors on venture capital network community ties changing and put forward relevant research hypotheses,construct longitudinal data sets of venture capital network community,and then use SAOM to empirically study hypotheses.Finally,pay attention to the impact of ties changing on structural evolution,the ABM is adopted to explore the impact of ties changing on the evolution of different venture capital network community structure.Compared with the previous researches,the main innovations of this dissertation are explained as following three aspects.Firstly,this dissertation breaks the trivial and scattered limitations of the influencing factors of venture capital network community ties changing.By means of abstract and summarize the important factors of venture capital community ties changing in a more comprehensive and systematic way,this study identifies the influencing factors from the firm level,inter-firm level and community level.A few scholars have explained the influencing factors of VC network community ties changing from different aspects,but the fragmentation of related research is scattered in a large number of literatures,and there are relatively few targeted research results.This research adopts grounded theoretical method to determine the multi-level influencing factors for ties changing of venture capital network community,the market status and community status factors at the micro level,the geographical proximity and cognitive proximity factors at the relationship level,and the structural embeddedness and relational embeddedness factors at the local community level.The research systematically extracts and summarizes the influencing factors that determine community ties changing,thus enhancing the integrity and systematization of the research on of venture capital network at the meso-level.Secondly,this dissertation deciphers the formation process and dissolution process of venture capital network community tis changing,clarifies the relationship between the influencing factors of community ties changing and the formation and dissolution of venture capital network community ties,and reveals the inherent law of the changing of venture capital network community ties.Jumping out of the research paradigm that only focuses on ties formation in the study of ties changing,it divides ties changing into ties formation process and ties dissolution process,and analyzes network community ties changing from a more complete perspective.By analyzing the influence of influencing factors on the formation and dissolution of community ties,it is found that structural embeddedness and relational embeddedness can promote the formation and persistence of community ties;cognitive proximity can promote the formation and persistence of community ties,geographic proximity can promote the formation of community ties but has no significant effect on the dissolution of community ties;market position can promote the formation and persistence of community ties,community status can promote the formation of the community relationship but promote the dissolution of the community relationship.The research conclusion can systematically reveal the changing mechanism of the venture capital network community ties,and enriches the research content of inter-organizational relationship dynamics.Thirdly,this dissertation constructs a complex nonlinear relationship between ties changing and the evolution of the venture capital network community structure,reveals the community behavior preferences of venture capital firms in the process of ties changing in different contexts,and analyzes how the continuous accumulation of the process of ties changing causes differences in the evolution of the venture capital network community structure such as clustering,status asymmetry,and accessibility.In order to break through the limitations of existing research that mostly explore the structure of the network community based on a static perspective,and build a co-evolve relationship between the micro-process of ties changing and the community structure.This study defines the community behavior of venture capital firms in the process of ties formation and ties dissolution,explores the differences in the evolution process and path of the community caused by the aggregation of community behaviors in the process of ties changing at different context,constructs the evolution model of venture capital network community,and through multiple simulation experiments,the evolution process and variable change process of the venture capital network community in different ties changing contexts are described.It is found that the influence of ties changing on the evolution of community structure has a strong contextual dependence,and solved the influence of different community behavior selection preferences in the process of ties changing on the dynamic evolution of community structure,which advances the contingency theory of community structure emergency.
