KIBS 嵌入对中国制造业贸易竞争优势的促动效应

随着产业的不断分化和价值链的延长,知识密集型服务业(KIBS)嵌入对制造业的贸易竞争优势产生了至关重要的作用。本文通过面板矫正标准误差(PCSE)模型实证中国KIBS对制造业贸易竞争优势带来的复杂效应。从整体KIBS对中国制造业贸易竞争优势的促动效应看,KIBS只对技术密集型制造业具有较大的正面促动效应,对资本密集型制造业几乎没有影响,而对于劳动密集型制造业反而具有明显的负作用。从具体KIBS看,科学研究服务和信息通讯服务业对制造业贸易竞争优势具有明显的正向带动作用,金融服务业的发展对不同要素密集度制造业的贸易竞争优势具有非对称性的影响,而商务服务则对各种要素密集度制造业的贸易竞争优势都具有明显的负面影响。

The Effects of Knowledge Intensive Business Services on the Competitive Advantage of China's Manufacturing Sector

As advanced elements,KIBS are embedded in the production and play an important role in shipping competitive advantage of manufacturing.This paper uses panel corrected standard error(PCSE) method to analyze the complex effects of Chinese KIBS on the competitive advantage of manufacturing.The results suggest that Chinese KIBS have obvious negative impact on competitive advantage of labor-intensive industries;while they have very significantly positive promoting effect on that of technology-intensive manufacturing;at the same time,they almost have no effect on competitive advantage of capital-intensive manufacturing.In addition,each KIBS sector has different effects on competitive advantage of manufacturing.Scientific research service and telecommunications &computer information services have significantly positive impact on competitive advantage of manufacturing.Financial service has asymmetric effects on different kinds of industries.As for business services,it has obvious negative impact on competitive advantage of all types of manufacturing.
