EMPIRICAL STUDY ON THE EXCESSIVE AGGLOMERATION OF MANUFACTURING INDUSTRIES AND ITS CONGESTION OF PRODUCTION FACTORS IN SOUTHEAST CHINA
用基尼系数等指标分析中国东南部制造业空间集聚趋势，发现部分行业集聚过度导致要素投入过剩和产出不足，并通过数据包络分析提出优化要素组合以降低成本、提高效率。
The tendency of spatial agglomeration of manufacturing industries was analyzed by meanings of Gini coefficient,MHHI and spatial separation index in this paper.According to the relationship between profit and scale indices of input production factors,we find that some manufacturing industries’ agglomeration becomes much more excessive in Southeast China,there was input surplus and output deficit on combination of factors when the progress of spatial agglomeration of manufacturing industries.The result of Data Envelopment Analysis(DEA) on slack variable shows that when there was a decrease in input factor or an advance in combination of factors,the cost of product can be cut down and the efficiency can be improved by increasing productivity in order to achieve a rational distribution.And it also can be used in tabling the agglomeration suitability of manufacturing industries and rationalization of industry.
