产品内国际分工与贸易的决定因素——基于中国零部件贸易数据的实证分析

Determinants of Intra-Product Specialization and Trade:an Empirical Study Based on China's Trade in Parts and Components

产品内国际分工与贸易研究已渐成气候,其决定因素的理论概括和实证分析却颇为匮乏。本文从物理、经济和社会三个方面概括了九个基本决定因素,并利用中国的零部件进出口数据作为对产品内贸易的近似度量对这些基本决定因素进行了实证检验。扩展的引力模型回归结果显示,大部分因素对不同分类的产品具有相似的效应,某些因素对进口和出口的效应差异明显。综合而言,中国参与产品内国际分工与贸易的潜力巨大。

Although intra-product specialization and trade is generally accepteo, me meoreucal summary of its determinants and the empirical test are not well founded. This paper identifies nine factors in physical, economic and social aspects, and tests these factors with trade in parts and components as a proxy. The empirical results of an augmented gravity model show that, with a few exceptions, most factors have similar effects on different products. China has a big potential to be involved into intra-product specialization and trade.
