摘要
采用产业区位基尼系数、空间分散度指数、MHHI系数、产业规模指数衡量中国制造业空间集聚程度,计算结果表明1980—2007年中国制造业空间集聚程度呈总体上升态势,并存在明显的"东倾"特征。通过生产要素投入—产出趋势分析研究,发现并非所有制造行业生产效率与产业聚集度成正相关,东南沿海一些制造业空间聚集过度,生产要素拥挤现象明显,生产要素配置存在输入剩余和输出亏空。数据包络分析结果显示:减少生产要素配置输入(剩余)、改进生产要素配置比例,不仅可降低生产成本,同时可通过提高劳动生产率从而改善生产效率,从而达到生产要素的合理配置的目的。研究结果对当今中国区域产业结构调整、东南沿海产业转移等具有实践启示和理论指导作用。
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.
