采用SNA的建筑企业组织角色权力评价及实证分析

采用社会网络分析法(SNA),以组织角色的业务流程工作流为基础,计算角色的出度量、入度量、中介中心度、接近中心度及总制约等网络权力指标.对所有单个指标的关系矩阵进行综合合成,构造组织角色的总关系矩阵.通过总关系矩阵的中心度量化,确定评价角色的评价结果和排序.以某建筑企业的成本管理等核心业务流程为实证,评价其组织角色的权力分配,提出组织优化的措施与路径.研究结果表明:组织角色权力的社会网络模型客观地反映建筑企业集分权的状况;大部分角色的组织层级与其总关系矩阵的中心性呈现正向关系部分,无规律的现象正好反映组织

Evaluation the Authority of Organizational Role for the Construction Enterprises based on Social Network Analysis

The evaluation model was based on the business process workflow of organizational roles with social network analysis, to calculate the network power indices including the sum of output degree, the sum of input degree, the betweenness centrality, the closeness centrality and the aggregate constraint. All the relational matrix of single index wase added to get the total-relational matrix of organizational roles. The centrality of the total-relational matrix was calculated to determine the results and orders of the evaluation roles. The core work flows which contained cost management from a large construction enterprise were chosen to build the evaluation model, and the centrality of the total-relational matrix was calculated to evaluate the authority of organizational roles. The countermeasures and pathways for organizational optimization were proposed. The research results show that: social network model of organizational role authority objectively reflects the situation of centralization and decentralization of construction enterprises; and most of organizational roles’ hierarchy and their centrality of the total-relational matrix are a linear relationship. Part erratic phenomenon just reflects the unreasonable part of authority allocation of organizational roles, and these roles are important objects of the optimization of organization and authority.
