摘要
综合运用相似系数、灰色关联度以及相对专门化指数和相对多样化指数,对西北地级城市的行业结构相似程度、关联程度和相对专门化行业进行研究,并将其与中原、关中、山东半岛三城市群进行对比。结果表明,以上3种方法的结合可以更加客观地测度行业分工的状况,得出西北城市行业分工有以下特点:(1)西北地级城市行业结构的差别很大,其行业结构的相似性存在着一定程度的空间自相关性。(2)西北地级城市的专门化程度较高,但这些城市之间的专门化程度差别较大,且其相对专门化行业大多为采掘业与电力、煤气及水生产供应业等较低层次的行业,同时在西北城市中核心城市拥有相对较高的多样化程度。
Based on similarity coefficient, grey incidence analysis, and relative specialization index and relative diversity index, we worked over the industrial division of cities at prefecture level in Northwestern China, and compared it with those of Guanzhong, Zhongyuan and Shandong urban agglomerations. Results are as follows ： （ 1 ） Similarity coefficient can be used to calculate the similarity between industrial structures of any two cities; grey incidence degree can be used to calculate the incidence degree between each industry and others; relative specialization index and relative diversity index can be used to show the condition of the specialization and diversity of industries of each city. （2） There is great difference among industrial structures of cities in Northwestern China, and the similarity of industrial structure of cities in Northwestern China are of spatial auto-correlation at a certain extent. The probabilities of division of each industry in Northwestern China are declining as follows： mining; production and supply of electricity, gas and water; services to households and other services; public management and social organizations ; education ; leasing and business services ; real estate ; management of water conservancy, environment and public facilities; scientific research, technical services and geologic prospecting; manufacturing; hotels and ca- tering services; health, social security and social welfare; culture, sports and entertainment; construction; finan- cial intermediation; transport, storage and post; information transmission, computer services and software; wholesale and retail trades. （3） Generally, specialization degrees of northwestern cities are high; however, there are great differences among them, and many of relative specialization industries of those cities are those low level industries such as mining and quarrying / production and supply of electricity, gas and water, in addition, main cities in northwestern China are of higher diversity.
