Abstract: Achievements of science & technology on the basis of informatization have brought about great changes of manufacturing. Basing on development practice of Zhejiang manufacturing, the paper manifested some facts of impact of technology-intensive industries upon manufacturing competitiveness. The adjustment of industrial structure of manufacturing in the Zhejiang province has been carrying out by mainly two ways, one is expanding of technology-intensive industries, and another is improving tradition industries by high technology. Technology-intensive industries have the visible action of pull on industrial effectiveness of manufacturing, but the action of pull has been slowing down recently other years. From the view of effect of industry relevance, the impact coefficient of technology-intensive industries are higher than that of other each industry, and industrial chain of technology-intensive industries are long enough to impact the development of other industries. On the other hand, the induction coefficient of technology-intensive industries has been ascending to the extent since 1987, and the action of restriction of technology-intensive industries on national economy and manufacturing is coming strengthened. From the view of effect of resources allocation, although the ratio of technology-intensive industries in the manufacturing isn't very high at present, the effect of resources allocation of technology-intensive industries is powerful, and is coming more powerful.

Key words: technology-intensive, manufacturing, competitiveness, positive study
