价值链差距与中间品产品内分工的溢出效应

Value Chains Gap and Intermediate Products' Intra-Product Specialization Spillover Effect

产品内分工是影响价值链的重要因素。本文分析了不同价值链差距层次下,中间品(包括半成品和零部件)产品内分工的溢出效应。研究表明,随着价值链水平所处条件分布的位置变化,中间品产品内分工对价值链的溢出效应变化趋势呈倒U型,这种作用对不同发展水平的国家具有异质性。

Intra-product specialization is an important element which affects value chains. This paper calculates interme- diate products＇ intra-product specialization spillover effect under the condition of different value chains gap. We find that this spillover effect trend has an inverted U-shaped relation, accompanied by conditional distribution diversification of value chains gap, and that this effect has heterogeneity to different development level countries.
