摘　　要：本文主要研究中国风险投资网络社群结构影响信息传播。遵循社群结构在认知临近性的影响下改变信息传播的逻辑思路,提出了风险投资网络社群结构的三个维度和信息传播的两种类型,采用实证分析法分别检验。研究发现:社群凝聚性对两种信息传播都是负向影响,地位差异和协调性对两种信息传播都是正向影响。凝聚性比地位差异影响项目信息传播更显著,地位差异比协调性影响项目信息传播更显著。凝聚性与地位差异对经验信息传播的影响差异不显著,地位差异比协调性对经验信息传播影响更显著。认知临近性会正向影响社群凝聚性与两种信息传播的关系,会负向影响社群地位差异与两种信息传播的关系,会负向影响协调性与两种信息传播的关系。The transformation of Chinese industrial structure has produced many emerging industries,then the venture capital can play a driving role.Based on the characteristics of network communities,this paper combines theoretical analysis and empirical test to make an in-depth analysis on the impact of network community structure change firm information dissemination resulting in community information dissemination changing.In this paper,China venture capital industry joint investment data of the CV(China Venture)source database was used to build a network community from January 1,2006,to December 31,2015.First,UCINET 6.560 was used to construct the VC network.Second,this paper uses the GN algorithm to extract the network community.This paper measures the network community with a three-year time window,for example in the 2006–2008 time windows we extract network community structure,and in the 2007-2009 time window investigate information dissemination,in the 2008-2010 time window calculate the performance,and so on.A total of 245 network communities were detected.First,basing on the structural analysis of cohesive subgroups,this paper proposes three dimensions(community cohesion,community status difference and community coordination)of the structure of venture capital network community.Two types of information dissemination(project information dissemination and experience information dissemination)are proposed according to the necessary information content for the existence and development of venture capital firms.Second,it is found that community cohesion has a negative effect on both types of information dissemination,while status difference and coordination have a positive effect on both types of information dissemination.The community cohesion has more significant influence on project information dissemination than community status difference,while community status difference has more significant influence on project information dissemination than community coordination′s.The influence of community cohesion and c
