珠三角产业结构的区位熵灰色关联研究

城市群作为经济发展的重要组织形式，在我国经济发展中正起着越来越大的作用。本研究采取区位熵灰色关联分析法并构建相应的指标，测度了珠三角城市群各城市和城市群整体与全国城市产业结构比较的总体相似程度。结果表明：1）近六年来珠三角第三产业的比重稳中提高，广州、深圳和城市群的第三产业比重超过第二产业；2）广州和深圳的产业综合实力最强、产业协调发展程度最高，属于综合发展型城市，其他各个城市则属于以优势产业为支柱带动发展的类型；3）珠三角住宿和餐饮业、房地产业、交通运输、仓储和邮政业、农业和建筑业的灰色关联度较高，各地区存在产业相似性，金融业的差异程度最大；4）城市群各城市和除农业外的所有产业的灰色关联度在2008年出现拐点。

Location Quotient Study on the Pearl River Delta Industrial Structure by Grey Correlation Method

Urban agglomerations, as an important organizational form, are becoming increasingly signiilcant in our eountry＇s economy. In this paper, we adopt grey correlation method based on location quotient and build related indexes to measure the similarity of industrial structure of the cities in the Pearl River Delta and the whole agglomeration with that of our country. The results are as followed ： （ 1 ） In the past six years, the composition of the tertiary industry in the Pearl River Delta increase steadily, the proportion of the tertiary industry in Guangzhou, Shenzhen and the agglomeration have already surpassed that of the secondary industry; （2） Guangzhou and Shenzhen＇s industrial comprehensive strength is the strongest and the degree of industrial development coordination is the highest, these two cities belongs to integrated industrial developing city, other cities belong to the type of development driven by advantage industries as pillar industries; （3） The grey correlation of hotels and catering services, real estate, transport, storage and post, agriculture as well as construction are relatively high, industrial similarity exists in each area, the difference in financial intermediation is the greatest; （4） The grey correlation inflected in the changes of all the industries except for agriculture, each city of the Pearl River Delta and the agglomeration in 2008.
