摘　　要：知识经济时代生产性服务业以其在区域创新系统中起到的巨大作用成为现代服务业中最为重要的部分,对城市空间结构与区域发展的作用表现突出。利用南京市生产性服务业企业数据,引入空间点模式分析方法,对建国后南京市生产性服务业时空集聚特征进行了系统分析。研究发现:南京市生产性服务业整体及各行业在空间均呈现出不同程度的集中分布特征,但不同行业的集中程度有很大差别,其中科学研究与综合技术服务业集聚特征最为明显,大多数行业集中半径均小于1km;同时,南京市生产性服务业企业空间集聚的"热点地区"有演化和迁移的现象,逐渐由老城区向外围地区特别是城市副中心推移,空间结构模式逐渐从单核心集聚模式到次一级中心集聚模式再向多核心集聚模式演变。In the era of knowledge economy producer services plays a huge role in the regional innovation system that makes it become the most important part of the modem service industry, which plays an outstanding role on urban spatial structure and regional development. In this paper, the point data of the producer service in Nanjing were used, with the help of GIS spatial statistical analysis software industry agglomeration measures such as M function, local spatial autocorrelation and kernel estimation were applied to comprehensively analyze the spatial pattern characteristics and evolution process of producer service in Nanjing after the founding of PRC. The results show that producer services in Nanjing as a whole or as different industries both present spatial agglomeration characteristics, but the degree of agglomeration were very different, scientific research and comprehensive technical services had the highest degree of agglomeration, most of the industries agglomeration radius were less than lkm. Meanwhile, the hot spots of producer services enterprises in Nanjing appear the evolution and migration phenomenon, is in the processing from the area of city center to the surrounding areas especially the sub-city area. The spatial structure mode is gradually changing from the single-core clustering model to the sub-center clustering model and further to multi-core rondel
