摘　　要：基于中国29个省份17个二位数制造业2000—2014年的省级面板数据,将制造业按要素密集度分类,利用非期望产出数据包络法求出制造业的效率,运用非线性平滑面板转换模型,分析不同地区不同类型制造业集聚水平与效率之间的关系。结果发现:(1)引入负外部性的制造业效率并非与集聚程度呈正向关系,这里将制造业分为过度集聚型、集聚推进型和集聚递减型,集聚递减型和过度集聚型负外部性严重影响着企业的生产效率;(2)东部沿海地区制造业已处在过度集聚阶段,而中、西部也出现了过度集聚现象;(3)东部沿海地区效率与铁路密集度成负向关系,而与能源消耗成正向关系,交通拥挤影响着经济发展,且东部地区的经济增长是以高能耗为基础的。Based on the provincial panel data of 17 two-digit manufacturing industries in China from 2000 to 2014, this paper classifies manufacturing industries by factor density and calculates manufacturing efficiency using unexpected output DEA. Adopting nonlinear PSTR model, the paper then analyzes the relationship between agglomeration and efficiency in different manufacturing industries in dif- ferent regions. The results show that ： （ 1 ） It＇ s not a positive relationship between manufacturing efficiency and agglomeration when introducing negative externality. Manufacturing industry here is divided into types of excessive agglomeration, advancing agglomeration and decreasing agglomeration. Negative externality severely hinders productivity in enterprises of excessive and decreasing agglomera- tion; （2）Eastern coastal areas are already experiencing excessive agglomeration while excessive agglomeration has only started to show up in western and central areas; （3） Eastern coastal area efficiency has a negative relationship with railway intensity, but a positive one with energy consumption. Traffic congestion hinders the development of economy, and economic growth in the eastern region is achieved at the cost of the high-energy consumption.
