生产性服务业的发展与城市发展相辅相成，其对于城市的经济发展、产业结构优化与升级转型起到了至关重要的作用，而城市的发展尤其是当下智慧城市的建设也在不断影响着生产性服务业。本文利用中国20个城市2003年-2011年的就业数据计算了生产性服务业的区位熵及空间基尼系数，分析发现以智慧城市为代表的新一代信息技术应用与发展在一定程度上对生产性服务业的发展产生了“挤压”效应，一方面促进了高端生产性服务业在城市的聚集，另一方面又刺激了低端生产性服务业向周边城市的扩散，最后文章从宏观与微观两个层面为政府提出了智慧城市建设中均衡发展的政策建言。

Producer Services has played a crucial role for the city's economic development, industrial structure optimization and transformation. In our paper，we used the 20 cities Chinese employment data to computing the aggregation of Producer Services by Location Entropy, Spatial Gini coefficient, explored the status of aggregation of Producer Services. We found that the Producer Services were on space diffusion trend while they are in the aggregation in the large city. Our paper pointed out that the city construction has influence on the Producer Service. Especially the development of the smart city has "squeezing" effect on the Producer Service, the one hand to promote the aggregation of Advanced Producer Services, on the other hand, to push the Low-end Producer Services diffusion to the surrounding city.
