价值链体系背景下产品内垂直分工的技术外溢研究——基于前向、后向与水平渠道关联分析

Research on Technology Spillover of Intra-Product Vertical Specialization in the Context of Value Chains System——Analysis Based on Forward,Backward and Horizontal Conduit Linkages

结合全球价值链体系背景,本文分析了中国制造工业参与产品内垂直分工经由前向、后向和水平渠道关联途径所产生的技术外溢效应。研究表明:(1)高强度的研发投入、FDI可以提升工业企业的全要素生产率、技术效率和技术进步;(2)价值链体系背景下产品内垂直分工经由前向、后向与水平三个渠道对中国制造工业总体产生了显著的技术外溢关联效应,提升了工业行业的全要素生产率与技术效率,促进了技术进步;(3)在融入全球价值链网络条件下,产品内垂直分工,经由前向渠道通过技术效率提升了高技术行业、高出口外向度和低资本劳动投入比例行业的全要素生产率,经由后向渠道改善了低技术行业的技术效率,提升了低出口外向度行业的全要素生产率,经由水平渠道提升了不同技术行业、不同出口外向度和高资本劳动投入比例行业的技术进步与全要素生产率。

This paper researches technology spillover effect of intra-produet vertical specialization on Chinese domestic manufac- turing industries through forward, backward and horizontal conduit linkages in the context of value chains system. Conclusions which the authors find are as follows. High intensive R＆D input and FDI can promote industries＇ TFP, TE and TP. Intra-product vertical specialization through forward, backward and horizontal conduit linkages in the context of value chains system produces technology spillover effect, promotes the whole industries＇ TFP, TE and TP. On the condition of value chains system, intra-product vertical spe- cialization impacts on TFP, TE and TP through different conduits.
