本文首先对西部产业集群的概况和基本类型进行分析,其次分析了西部产业集群形成的条件,本文认为,产业集群的集聚条件是产业集群的外部形成条件;由竞争优势和组织优势形成的产业集群的集群优势,使企业产生了集聚欲望,是产业集群形成的内部动力;在外部条件和内部动力同时具备的前提下,政府利用自身的角色优势,通过“自下而上”地培育或者“自上而下”地规划最终使产业集群形成。 This paper first analyzes the general situation and basic types of the western industrial clusters, and then analyzes the conditions for the formation of the western industrial clusters. This paper argues that the industrial agglomeration’s agglomeration conditions are the external formation conditions of industrial clusters. The industrial clusters formed by competitive advantages and organizational advantages Of the cluster advantage, so that enterprises have a desire to gather, is the formation of industrial clusters internal motivation; in the external conditions and internal motivation at the same time have the premise, the government use their own role advantages, through “bottom-up” to cultivate or “Top-down ” planning eventually led to the formation of industrial clusters.
