借助规模指数计算分析了长三角制造业总体集聚态势、并利用专业化系数等指标进一步分析了制造业细分行业的集聚态势。选择其中集聚程度较高且处于上升通道的行业作为研究对象,利用要素投入强度的产出效率指标计算分析了历年来各行业的集聚效率,依据此指标将这些行业分为尚有集聚前景行业、集聚适度行业、集聚过度行业,并分析了这三类行业的特点。
With the help of the scale index, this paper analyzes the overall agglomeration trend of the manufacturing industry in the Yangtze River Delta, and further analyzes the agglomeration trend of the manufacturing subdivision industry with the index of specialization. Select the industries which have a high degree of agglomeration and are in the ascending channel as the research object, calculate the efficiency of agglomeration over the years by using the output efficiency index of factor input intensity, and divide these trades into industries with agglomeration prospect according to this index, Agglomeration of moderate industry, agglomeration over the industry, and analyzed the characteristics of these three types of industries.
