单独对国家高新区或产业集群的研究已经很多,但用产业集群的思想和理论研究国家高新区产业积聚度的文献却很少。本文首先回顾产业集群测算的常用方法,然后根据高新区的产业特点和测算目的,选择并修正了产业集群的识别方法——区位熵系数法LQ (Location Quotient)。随后,分四步对高新区产业集聚度进行测算:1)选定测算聚集度的产业范围;2)明确四类测算产业的权重;3)计算产业积聚度;4)采用0-1方法处理,并排序。最后,根据积聚度的计算结果,把高新区分为四个等级,在每个等级中选择比较典型的高新区,重点分析影响高新区排序的相关因素。

In previous literature, there were many researches about the state's high-tech development zones or industrial clusters, however, there are little studies on the degree of industrial accumulation within the state's high-tech development zones building on the idea and theory of industrial clusters. Firstly, the methods commonly used to measure the industrial clusters are reviewed, then, according to the industrial characteristics of the high-tech zones and the purpose of calculations, a method to identify industry clusters-Location Quotient(LQ) coefficient is chosen. Subsequently, there are four steps to measure the degree of industrial accumulation within the state's high-tech development zones, 1) selecting the scope of industries measured the degree of industrial accumulation, 2) weighting four relative industries , 3) calculating the degree of industrial accumulation, 4) using a normalization method, that is, re-scaling the data for standardization. Therefore, the degree of industrial accumulation within the state's high-tech development zones can be ranked. Finally, depending on the rank, high-tech development zones are classed into four grades, and a typical zone within every grade is chosen to analysis relative factors which affect the rank.
