基于多层网络的中国企业风险投资(CVC)影响力动态评价研究

Dynamic Influence Evaluation Based on Multi-Layer Network of Chinese Corporate Venture Capital(CVC)

影响力是对被评价主体能力的综合的动态的反应.企业风险投资(corporate venture capital,CVC)作为联系产业资本与技术创新的重要方式,对促进创业企业发展和激励创新有不可忽视的作用.对其影响力进行动态评价,可以综合反映其动态能力,有利于其他主体对其进行直观评估.文章基于CVC多层社会网络,构建了包括整体网-社群网-自中心网的多维影响力评价模型,并加入时间权重,对时序数据提出基于移动时间窗的动态评价模型.该模型既能对被评价对象在静态时间窗上进行多维度影响力评价,又可以反映动态时间窗中影响力变化趋势及其时间延续性,动态衡量被评价对象的多层次综合影响力.文章采用该模型对中国国资背景的CVC进行了动态影响力评价,验证了所研究在实际应用上的有效性.该方法将多层社会网络与影响力综合评价模型相结合,为动态评价方法研究提供了新的思路,可用于对具有网络特征和时间延续性的对象进行动态综合评价.

Influence reflects comprehensive dynamic ability of the evaluation objects.Corporate venture capital(CVC)is a key paradigm of connection between industrial capital and technical innovation which play important role in promoting startups and incentive innovation.Influence evaluation which reflects comprehensive dynamic ability of CVC could provide direct judgement to other subjects for different purposes.Based on multi-layer social networks of CVC including the whole networksubgroup network-ego network,our research constructs a multi-dimensional influence evaluation model with time weight for time series data.The model not only shows the static multi-dimensional influence of evaluation objects in each time window,but also reflects the trend and continuity of influence in moving time-windows,and dynamically measure the comprehensive influence of evaluation objects.Applied the dynamic evaluation model for Chinese CVC institutions supported by state-owned enterprises or capital,it shows the effectiveness of this study in practical application.The method combines the multi-layer social network with the comprehensive evaluation model of influence,which provides a new research perspective for the study of dynamic evaluation method,and can be used for the dynamic comprehensive evaluation of objects with characteristics of network and time continuity.
