以北京市西城区西四南大街-西四北大街-新街口南大街-新街口北大街沿线的婚纱摄影、电气五金、乐器和服装四种同类商品集聚型商店为例,探讨了该布局模式的形成机制及其效应。论文认为,在市场竞争中获取较大的份额是这类布局模式产生的基本原因;搜寻成本的存在和商家与消费者间交流产生的信息溢出效应有利于这种集聚;相对于分散型模式,同类商品集聚型布局模式在市场中更具有竞争力,因为它降低了交易成本,使商家和消费者都获利;同类商品集聚型布局模式更适应于产品有差异且类别众多的商品,不应与其他的布局模式形成对立。
Using the examples of four types of shops- wedding dress photography, hardware, musical instrument and garments of congener merchandises along the South Xisi Street-the North Xisi Street-the South Xinjiekou Street-the North Xinjiekou Street in Beijing xicheng District, we discussed the formation mechanisms and the effects of the commercial pattern of congener merchandises agglomeration. It shows that the acquirement of more market share in competition is the primary reason for the appearance of this commercial pattern; the existence of searching costs and information spillover effects coming from the intercommunication between merchants and customers are advantageous to such agglomeration. It also indicates that the commercial pattern of congener merchandise agglomeration is more competitive in the market than dispersive one. Because the former decreases the transaction cost and therefore benefits both merchants and customers. Moreover, the commercial pattern of congener merchandises agglomeration is more suitable for merchants with diversified products, and should not be opposite to other commercial patterns.
