考虑类型差异的长三角制造业结构趋同的现实考查

An Empirical Investigation on the Structural Convergence of Manufacturing with the Consideration of the Difference of Types within the Delta Area of Yangtze River

在简要回顾产业细分条件下长三角制造业同构问题相关研究的基础上,对制造业进行了分类。利用结构重合度指数对分类后的长三角不同类型制造业的同构水平进行了测度与分析。结果表明,某些类型产业如轻工业等经过趋异化发展已经不存在同构现象,多数类型产业虽经历了趋异化发展历程但仍然处于同构状态,还有部分类型产业如原材料产业等经历的则是趋同化发展并导致了同构水平不断增高,这才是近期长三角制造业转型升级中最需要关注的问题。

On the basis of briefly reviewing relevant literatures, which are on the structural convergence of the manufacturing within the Delta Area of Yangtz River under the industrial subdivision condition, the article categorized the industries of the area. The level of the similar structure of different types of manufacturing in the Delta Area of Yangtze River were measured and analyzed by using the method of structure coincident in-dex. The results showed that the phenomenon of similar structures, through the development of divergence, has not yet exist in certain types of industries, such as light industry. The phenomenon of similar structures, although have experienced the development of divergence, still could be observed in most types of industries. Some types of industries, such as raw material industries, are experiencing or have experienced the development of convergence, and the high level similar structures is increasing. This is what should be concerned the most in the recent manufacturing transformation and upgrading within the Delta Area of Yangtze River.
