企业项目选择及组合、社会网络变化与战略调整——基于城市基础设施行业的纵向案例分析

Project Selection and Portfolio,Social Relationship Network Change and Strategic Adjustment of an Enterprise——A Longitudinal Case Study Based on Municipal Infrastructure Industry

基于社会关系网络动态视角,通过对案例企业的长期跟踪分析,首先,发现企业社会关系网络的子网络构成,并探索性的通过网络行为主体、网络关系内容和网络关系结构测量企业社会关系网络及其子网络变化。其次,探索子网络变化对企业项目选择和战略调整的异质性作用,建立了企业社会关系网络变化到企业战略调整的过程模型,印证了企业战略调整可以是自然演化的推断。最后,现有研究普遍认为战略是企业项目选择及组合的指南针,本文发现项目选择及组合也可以先于企业战略并诱发企业战略调整。本文提出和印证的概念不仅丰富了企业战略和项目管理理论的内涵,也为企业战略调整和项目管理实践提供指导。

Through long-term tracking and analyzing target enterprises from the dynamic perspective of social relation networks,this paper reveals the composition of an enterprise＇s social relationship network,measures the changes of its social relationship networks and sub-networks through the behavior main body of networks,the relation content of networks and the relation structure of networks. Then,the paper explores the heterogeneous effects of these sub-network changes on the enterprise＇s project selection and the strategic adjustment,constructs a process model from enterprise＇s social relation network changes to enterprise＇s strategic adjustment,confirms the inference that the enterprise＇s strategic adjustment can be a natural evolution. Finally,facing the popular opinion that strategy is a guide of an enterprise in selecting project and structuring portfolio,this paper argues that an enterprise can also select project and structure portfolio first and then set up its strategy,thus making it easy to make necessary adjustments to the strategy. The concepts put forward and confirmed by the paper not only enrich the connotation of the theory of enterprise strategy and the theory of project management but also provide guidance for the practice of strategic adjustment and project management.
