专业化产业集群的起源——基于古诺寡头竞争框架的博弈分析

The origin of specialized industrial clusters——Based on game analysis in the frame of cournot oligopoly competition

文章通过古诺寡头竞争的博弈模型,考察了专业化产业集群的形成源于区域经济效应和集聚经济效应合力的大小。当贸易成本较高时,地方化的市场需求导致厂商区位选择分散;当贸易成本降低时,有利于厂商集聚,但集聚究竟发生在哪一个区域,则取决于区域经济效应和集聚经济效应的叠加效果。集聚经济效应有可能阻碍区域经济效应的发挥,但是,集聚经济效应也有可能放大区域经济效应,特别是在专业化产业集群形成的初期,更是如此。

The game model of cournot oligopoly competition in this paper shows that the formation of specialized industrial clusters comes from forces of composition of regional economic effect and agglomerate economic effect. When trade costs are high, localized market demand leads to dispersion of firms; lower trade costs can lead to agglomeration of firms, but where the agglomeration take place is decided by the folded effect of regional economic effect and agglomerate economic effect. It is possible that agglomerate economic effect could deter the exertion of regional economic effect, but we can＇t deny that agglomerate economic effect could amplify the effect of regional economy, especially in the initial stage of formation of specialized industrial clusters, it is more.
