摘　　要：采用城市相对专业化指数、城市间相对专业化指数、行业相对专业化指数和集聚指数等4个指标对长江中游城市群2003--2014年的生产性服务业分工水平和集聚程度进行测算，然后利用空问自相关模型对其空间效应进行定量分析。研究发现：①长江中游城市群的生产性服务业相对专业化程度总体较低，南昌、武汉和长沙这3个区域中心城市在该区域生产性服务业专业化分工体系中呈现出多样化特征；每个城市一般都有1-3个生产性服务行业的相对专业化程度较高；城市之间生产性服务业的相对专业化指数较低，彼此间专业化分工特征不明显，产业同构现象比较普遍。②长江中游城市群生产性服务业发展存在明显的核心一外围格局，且该格局导致的空间效应主要表现为虹吸效应。③长江中游城市群生产性服务业发展产生的虹吸效应在250km范围内最明显，超出此范围后虹吸效应迅速大幅度减弱。Accurately mastering the spatial division and spatial effects of producer services is of great significance to regional development integration. Use the city relative specialization index and inter city relative specialization index, relative specialization index and agglomeration index to calculate the level of division and the degree of agglomeration of producer services in the urban agglomeration in the middle reaches of Yangtze River from 2003 to 2014, and then use the spatial autocorrelation model for quantitative analysis of the spatial effect. The study found that： （1） Yangtze River city group of productive service industry relative specialization degree is generally low, Nanchang, Wuhan and Changsha center of the 3 areas of the city showed a variety of features in the area of productive service industry specialization system; each city generally has a relatively high degree of specialization of production 1- 3 service industry; relative specialization index between the city productive service industry is low, each specialization characteristic is not obvious, the phenomenon of industrial isomorphism is common. （2） there exists a clear core periphery pattern in the development of producer services in the middle reaches of the Yangtze River, and the spatial effect of the pattern is mainly the siphon effect. （3） the siphon effect produced by producer services in the middle reaches of the Yangtze River is the most obvious in the range of 250Km, and beyond this range, the siphon effect is greatly weakened.
