生产性服务业对制造业前向和后向技术溢出效应检验

Empirical Analysis of Forward and Backward Technology Overflow Effect from Producer Services to Manufacturing Industry

本文分析了生产性服务业通过前向关联和后向关联对制造业产生技术溢出效应的内在机理。运用1999～2008年制造业行业面板数据实证检验技术溢出效应,并基于不同要素密集类型制造业和三大经济带制造业进行相应分析。得出如下结论:(1)FD I是制造业技术进步的主要原因,生产性服务业对制造业技术效率产生前向的正溢出效应,后向溢出效应不显著。(2)生产性服务业对资本密集型制造业技术效率前向正溢出效应最强,对技术密集型制造业产生微弱的后向正溢出效应。(3)长三角地区生产性服务业对制造业技术效率产生前向正溢出效应,环渤海经济圈和珠三角地区与之相反,生产性服务业对制造业产生后向正溢出效应。

This paper investigates the machanism of forward and backward technology overflow effect of producer services to manufacturing. And makes an empirical study based on manufacturing industries＇ panel data from 1999 to 2008. The appropriate analysis is used to different manufacturing types of elements density and three economic zone. According to the theoretical study and empirical research, we conclude the following results. Firstly, FDI is the main reason of manufacturing＇s technical progress, the forward technology overflow effect from producer services to manufacturing is positive, and the backward technology spilllover effect is insignificant. Secondly, the forward technology overflow effect is strongest in capital-intensive manufacturing, the backward technology spillover effect is a little weak in technology-intensive manufacturing. At last, the forward technology spillovers is significantly positive in yangtze river triangle economic zone, and the direct opposite conclusion is applied to the other two regions.
