在东北振兴背景下,对东北三省制造业竞争力和集聚水平进行测度尤为重要.运用偏离份额和区位熵,对1999年~2008年20个两位数制造业的产业结构和竞争力变化以及集聚水平进行测评,得出以下结论:①快速增长型部门由5个上升为8个,而竞争优势部门由8个增加为12个.②竞争优势部门从石化产业向医药、交通运输等制造业转移,显现出高技术化和技术密集型特征.③总偏离量为正值的部门达11个,产业结构对经济增长贡献为565.73亿,竞争力为977.39亿,总偏离量1543.12亿.④地理集聚和专业化程度高的制造业部门中辽宁有5个、吉林和黑龙江各有3个,具有竞争优势的制造业部门其专业化和集聚化程度也很高,产业集聚对提升制造业竞争力作用明显.
It is important to assess the variation in industrial structure and competitive- ness of manufacture industries and industrial agglomeration in northeast china. The article combined shift-share and location quotient ways to estimate twenty two-digit manufacturing data from 1999 to 2008 ,the diversification of industrial-mix effect, competitive advantage and the level of geographical concentration. ①The fast growth manufacture industries rose from 5 to 8 and the industries which had competitive advantage increased from 8 to 12. ②The manufacturing industries of competitive advantage transferred from the petrochemical industry to the pharmaceutical, transport equipment industries, the variation revealed high-technology-oriented features. ③The number of industries which the total shift is positive value are 11, the growth of industrial structure attained 565.73 billion, however, The competitive advantage brought 977. 39 billion, the total shift was 1543.12 billion. ④The geographical concentration and specialization of manufacturing industrial departments, the number was five in Liaoning, three in Jilin and Heilongjiang, the departments which had not only competitive advantage, but also the level of specialization and agglomeration were higher. Industrial agglomeration played important roles in promoting competitive power.
