企业竞争关系演变的复杂网络分析——以广东省软件产业为例

The Complex Network Analysis of the Enterprise Competitive Relationships Evolution——Take Software Industry in Guangdong Province as the Example

首先根据2002～2006年每年度广东省软件产业内企业及产品的数据，分年度构建了企业竞争关系复杂网络模型；然后用各种静态几何量分析了每年度网络的结构属性，比较了不同静态几何量之间的关系，并探讨了网络增长的动力机制和经济学背景。通过分析发现，每年度网络的顶点度都服从幂律尾部分布；同时，网络具有小世界特性，并有增长性和偏好性，从而得出这些网络都近似于无标度网络和小世界网络的结论。最后，本文还讨论了软件企业竞争关系复杂网络分析在宏观、微观和动态演变方面的产业组织学意义和启示。

First, this paper constructs the annual competitive relationship complex network models among enterprises according to data of enterprises and products among software industry from the year 2002 to 2006 in Guangdong Province, China. Then, the authors analyze network structure properties each year with the different static indexes, compare relationships between different static indexes, and discuss the dynamic mechanism and the economic background of the network growth. The authors analyse that node degree of the annual network follows the power - law tail distribution and the networks show the characteristics of clear small - world property, growth and preference, so we conclude that these networks approximate to scale - free network and small - world network. Finally, this paper discusses macroscopical, microcosmic and competitive relationship dynamic evolutional industrial significance and inspiration of the competitive relationship complex network in software industry.
