中文摘要：

本文通过构建服务关联指数指标体系测算我国各地区的服务关联水平，从全国和东中西部地区两个层面的2005—2010年省（市）级面板数据模型实证研究服务关联对加工贸易集聚的影响。研究结果表明，服务关联总体上对地区的加工贸易集聚产生显著的促进作用，说明服务关联显著影响地区参与国际分散化生产的深度和规模，但在中西部地区并不总是正向显著的。

英文摘要：

Fragmentation of production coexists with regional agglomeration, how can service links have any impact on the economic activity which seem contradictory？ Based on the research of effects of service links in fragmentation of production , this paper first builds service link index to calculate the quality of each region＇s service links based on the relative data among 31 provincial regions in 2005 -2010, and then set up a panel data model and research the effects of service links on pattern of agglomeration by empirical analysis from the whole and eastern, central and western regions of China. As expected, the empir- ical research results show that service links promote the agglomeration of processing trade in the whole country obviously, but it is not always significant in central and western regions of China.
