企业规模与竞争关系网络互动关系实证研究——以中国啤酒企业为例

An Empirical Study on the Interaction of Enterprise Scale and Competition Network:Evidence From Chinese Beer Enterprise

从复杂网络和计量经济的交叉视角研究企业相互间的竞争关系。通过企业度、平均路径长度与集聚系数3个拓扑属性,分析网络演化过程中企业规模与竞争关系网络的互动关系;以2000年、2006年和2012年中国啤酒企业竞争关系网络为对象进行实证研究,采用网络中的拓扑属性为自变量,建立了关于企业规模的计量经济模型。研究结果表明:(1)企业规模与节点平均路径长度及其集聚系数表现出正相关性,与节点的度呈负相关性;(2)啤酒企业竞争由无序局面,逐渐形成了"四极多核"的格局:企业竞争极化现象主要集中在第1梯队(雪花、青岛、燕京及百威英博),多核化竞争发展趋势呈现于第2梯队。

From the perspective of the combination of complex network and econometric, this paper studies the activities of the enterprise competition, by building the network model of Chinese beer enterprise competition relationship and analyzing the influence of network model parameter on the scale of beer enterprise in the evolution of network. Taking the network of 2000, 2006, 2012 years as examples, we choose alternative network topological properties instead of the network parameters, and establish the econometric model of enterprise scale. The results imply that the scale of enterprise has a positive correlation to the node＆#39;s path length and cluster coefficient, a negative pertinence to the nodes＆#39;degree. In terms of trends, competition between beer companies transfers from disorder into order gradually, which brings a new time namely so-called “four-centers with multi-cores situation”. In the new time, the first tier （ Snow, Tsingtao, Yanjing and Anheuser-Busch InBev） is on the leading position while the rest ones show the trend of multi-cores competition.
