中美汽车零部件产业内贸易的发展程度及其影响因素

本文用Grubel和Ramkishen产业内贸易指数考察了中美汽车零部件产业内贸易的发展程度,并从中选取了市场结构、产品多样化、中美汽车贸易总额和中美汽车工业总产值四个因素,并建立多元回归模型来分析各因素对中美汽车零部件产业内贸易的影响。分析结果表明,这四个因素对对中美汽车零部件产业内贸易均起着正向促进作用,其中以产品多样化程度最为显著,市场结构指数次之,这说明,中美两国汽车产业的技术发展是两国汽车零部件产业内贸易的主要影响因素。

Development Degree of Intro-industry Trade in Automobile Components between China and America and Its Influence Factors

This article applies Grubel and Ramkishen intro-industry trade indices to analyze the development degree of intro-industry trade in automobile components between China and America. It analyzes the four selected factors, market structure, product diversification, total trade of automobile between China and America and total production value of automobile industry in China and America, that influence the intro-industry trade in automobile components between China and America. It also analyzes the influence which these factors put on via multi-variable regression. The result shows that these four factors all have positive impacts on intro-industry trade in automobile components between China and America, in which the product diversification is the most important, while the market structure takes the second place, which implies that technology development in automobile industry in China and America is the major factor influencing the intro-industry trade in automobile components between China and America.
