中文摘要：

经济活动的相对密度会对自身效率产生影响。该文利用空间基尼系数、区位熵及比较劳动生产率等指标对我国服务业聚集状况及对生产率的影响进行分析。结果发现：我国服务业以及内部各行业的集聚程度呈上升趋势，集聚程度较高的行业主要集中在现代服务业，社会性服务业集聚程度较低，多数地区的服务业区位熵大于1，区位熵最高的是北京，但服务业集聚对服务效率的影响不显著。

英文摘要：

The relative density of economic activity will have an impact on its own efficiency. The paper uses spatial Gini coefficient, location quotient and comparative labor productivity to analyze the agglom- eration condition of the service industry in China and its influence on productivity. It turned out that the aggregation of China＇s service industry and its internal branches tends to intensify. The modern service industry is listed among the industries of a higher aggregation, and the level of agglomeration in social services is low. The location quotient of service industry is greater than 1 in most areas, and the highest is in Beijing. But the impact of agglomeration of service industry on service efficiency is insignificant.
