沿海城市产业结构趋同问题探讨——以天津、青岛、大连为例

DISCUSSION ON THE ISSUE OF INTERREGIONAL INDUSTRIAL STRUCTURE SIMILARITY ——A CASE STUDY OF TIANJIN,QINGDAO AND DALIAN

产业结构趋同是制约中国经济持续发展的重要因素之一,在沿海城市等经济较发达地区表现得尤为明显。采用天津、青岛和大连3个沿海城市近10年工业产值,运用产业结构相似性系数、相对专业化指数和地区间专业化指数,从纵横两个角度由3次产业到制造业逐层对3市的产业结构趋同问题进行分析。研究结果显示:3市在三次产业层面存在严重趋同,而具体到各制造业层面则相似性并不明显。分析区域产业结构趋同现象产生的原因以及存在的合理性与消极面,并在此基础上对3市如何优化产业结构提出建议。

The industrial structure convergence is one of the important factors of restricting China＇s economic sus- tainable development, and it is remarkable in the developed areas as coastal citys. Adopting the industrial output of three coastal citys Tianjin, Qingdao and Dalian in the past ten years and using industry structure coefficient of similarity, industrial structure convergence problems are analyzed from two aspects, and it is conducted from ag- riculture, industry and other parts except the former ones to manufacturing. From this study, serious convergence of three industries level of the three cities is found, but similarities of manufacturing level is not obvious. Besides, the causes and the rationality of the existence and negativity of structure convergence are found. Based on it, some suggestions about optimizing the industrial structure of the three cities are proposed.
