The effect of external linkage on hub-spoke industrial cluster

Although industrial cluster attracts great attention, it still holds some research deficiencies. Rare exploration about cluster's external linkage is the most significant one. To make up such deficiency, this paper takes hub-spoke industrial cluster as example to analyze the influence and effect path of external linkage on cluster. Finally for more information about external linkage's effects, this paper identifies the order of different external linkage forms with ZhongGuanCun(ZGC) as research object and further analyzes the reason of the final quantitive result.
