城市群是国际竞争的基本单位,科学地测量城市群的产业结构与分工的程度,具有十分重要的实践意义。针对相似系数法和区位法等传统度量方法的不足,首次提出了区位熵灰色关联分析法,并以中原城市群为例进行了实证研究。结果表明,运用区位熵灰色关联分析法测度区域产业结构,不仅可以测度两地区产业结构的总体相似程度,而且还能反映地区产业的专业化、比较优势和区域分工的程度,可以定量地测度两地区产业的总体相似性,两地区不同产业的相似性。

The urban agglomerations are the fundamental units in the international competition. It is important to optimize its interior industrial structure, make the city function for supplementary each other, enhance the economical relation division and the cooperation and increase the economic integration degree. Therefore, it is very important to scientifically evaluate the degree of the industrial structure and division of the urban agglomerations too. The paper puts forward the grey correlative analysis method as the base of location quotient for the first time and conduct an empirical analysis on urban agglomerations of Henan province in view of the in sufficiency of the similar coefficient methods and the location quotient methods traditionally. The result indicated that compared with the similar coefficient methods only, the method may estimate the similar degree of the industrial structure between two areas and reflect the local industrial specialization, the comparison superiority, the region division degree. Moreover, compared with the location quotient methods only, it can quantificationally estimate the overall similarity of the region industrial structure between two areas. Compared with using the location quotient and the similar coefficient synthetically, it can quantificationally estimate the similarity of the different industry.
