利用社会网络分析方法构建了一个区域内的产业排污竞争网络模型,节点表示每个企业,边的权重表示连接的两个节点中一个企业外部性效应影响到另一个企业的利益。另外,研究了网络中的结构参量,结果表明:竞争网络中只有少数节点发挥着中介作用;边权服从于指数分布,边权的差别程度比较小,网络中每个企业受到的竞争压力趋于平均;电力企业的集聚系数排名靠前,以这些企业为组织中心节点群内的交易竞争程度高,应提高企业内部的排污技术水平,减小来自外部的排污竞争压力。通过这些分析发现,要完善区域企业的排污管理,网络分析不失为一种可行而有效的方法。
A social network analysis method is used to construct a model of industrial sewerage network in a region. Nodes represent each enterprise. The weight of the edge indicates that the effect of one enterprise externalities on the two connected nodes affects the interests of the other enterprise. In addition, the structural parameters in the network are studied. The results show that only a few nodes in the competing network play an intermediary role; the subordination of the power to the exponential distribution has a small degree of difference in edge power; and the competitive pressure on each enterprise in the network tends to On average, the agglomeration coefficient of electric power enterprises is in the front rank, and the competition among these enterprises in the node group of the organization center is high. The sewage technology inside the enterprise should be raised to reduce the pressure of competition from the outside. Through these analyzes, it is found that it is a feasible and effective way to improve the sewerage management of regional enterprises and network analysis.
