基于修正的Ellision和Glaeser的γ指数分析以及利润状况分析均表明,中国制造业空间集聚度呈下降趋势。修正的γ指数还表明,制造业的30个子行业中,大部分行业的空间集聚度都呈现出下降趋势。设计的展示产业空间集聚和产业增长之间关系的空间集聚效应模型研究显示:制造业的增长促进了制造业的空间集聚,相反,制造业的空间集聚亦促进了制造业的增长;制造业资产份额与制造业空间集聚度成反向变动关系;技术水平的变化对制造业空间集聚并没有显著的影响作用,而资本是制造业产业增长的主要影响因素。
The γ-index analysis and profit status analysis based on the modified Ellision and Glaeser indicate that the spatial concentration of manufacturing industry in China shows a downward trend. The revised gamma index also shows that most of the 30 sub-sectors in the manufacturing industry show a downward trend in spatial concentration. The design of the spatial agglomeration effect model that shows the relationship between industrial agglomeration and industrial growth shows that the growth of the manufacturing industry has promoted the spatial agglomeration of the manufacturing industry. On the contrary, the spatial agglomeration of the manufacturing industry has also promoted the growth of the manufacturing industry. The relationship between share and manufacturing spatial agglomeration is in a reverse relationship; the change in technology level has no significant effect on the agglomeration of manufacturing space, and capital is the main factor affecting the growth of the manufacturing industry.
