地理距离如何影响全球价值链合作:理论模型与国际经验

How Does Geographic Distance Affect the Global Value Chain Cooperation?Theoretical Model and International Empirical Evidence

本文基于拓展的Helpman等(2003)理论模型及2000—2011年62个经济体数据,考察了地理距离如何影响全球价值链合作问题。理论分析表明,当地理距离位于某一特定区间时,地理距离与全球价值链合作度之间呈现出倒"U"型关系。进一步的实证结果显示,由于样本期内各经济体间的地理距离大都位于倒"U"型曲线的左侧,故地理距离与全球价值链合作度主要呈现出正向线性关系,即随着地理距离的增大,两个经济体间的价值链合作会随之加深。此外,地理距离对各类型经济体之间价值链合作的影响存在一定差异,对不同类型经济体之间价值链合作的影响大于同类型经济体,对发达经济体之间价值链合作的影响大于发展中经济体。这一研究深化了对地理距离与对外贸易关系的理解。

Based on the extended Helpman et al.(2003)and 62 economies’data from 2000 to 2011,this paper discusses how does geographic distance affect the cooperation in global value chain(GVC).The results show that the relationship between geographical distance and GVC cooperation presents an inverted U-shape within a certain range.Further empirical results indicate that the effect is positively linear,for most geographic distances are on the left side of the inverted U-shaped curve.That is,geographic distance does good to GVC corporation.In addition,the influence is greater on different types of economies and on developed economies.This research deepens our understanding of the relationship between geographical distance and trade.
