基于修正的E-G指数测算我国制造业20个行业1993-2012年的集聚度，并从不同方面对其演进态势进行分析，同时考察制造业各行业集聚地分布变化以及区域产业转移的特点。研究发现，目前我国制造业总体集聚程度偏低，集聚度的增长态势呈现倒U型曲线特征；不同行业在不同时间段内呈现不同的增长特点；制造业主要分布于东部沿海省份，产业地区分布不均由强化变为逐渐减弱；部分行业在近年来出现向其他区域特别是中西部地区转移的态势。%This study measures the agglomeration degree of China’s 20 manufacturing industries from 1993 to 2012 by using the modified E-G index,and analyzes the changing trend of the industrial agglomera-tion degree from different aspects. Finally,this paper analyzes the changing trend of regional industrial ag-glomeration and the trend of industry transfer. The results indicate that the overall agglomeration degree of China’s manufacturing industry is low at present,and the growth rate of China’s manufacturing industrial ag-glomeration degree shapes inverted U curve,but different industries show different growth characteristics in dif-ferent periods. It also indicates that China’s manufacturing industries are mainly distributed in eastern coastal provinces,and the uneven regional distribution of the industries becomes weakened by strengthening. The study also finds that some industries have transferred to other regions especially to the central and western re-gions in recent years.
