Abstract: We gather 14 kinds of service industry from 2003 to 2010 as samples in this paper to study the effect of service industry and political intervention to the agglomeration of service industry. And discuss the substitution effect of social capital and government intervention in the service industry agglomeration. The study found :There is a "inverted U" type structure Between social capital and service industry agglomeration .which means that in a certain range the social capital has a positive effect on the service industry agglomeration ,After the inflection point , social capital has a negatively effect on the service industry agglomerations.We also found that the role of social capital and government intervention are interchangeable in the service industry agglomeration .In other words ,when no government intervention is available ,social capital tends to have a stronger influence on the service industry agglomeration ,vice versa .

摘要： 本文以全国2003—2010年间的14类服务业集聚为样本，研究社会资本、政治干预对服务业集聚的影响，并进而探讨了社会资本与政府干预在服务业集聚影响方面的替代作用。研究发现：社会资本与服务业集聚之间会呈现“倒U”型结构，即在一定范围内，社会资本与服务业集聚正相关，超出拐点值后，社会资本与服务业集聚负相关。地方政府干预与服务业集聚正相关。而且社会资本与政府干预在服务业集聚中所起的作用可以相互替代。即当政府干预较少时，社会资本对服务业集聚有更强的影响力，反之亦反。
