中日两国双边产业内贸易发展现状研究

A Study of the Bilateral Intra-industry Trade between China and Japan

衡量产业内贸易发展程度的常用公式是格鲁贝尔·劳埃德公式,但该公式在衡量双边产业内贸易上存在不足。而使用伯格斯特朗德公式,考察中日两国双边产业内贸易的发展现状,并对其原因和发展前景做出分析,从而得知:中日双边产业内贸易发展程度稳中有升,反映了两国的比较优势和经济结构特点。中国应该从宏观和微观两个层面改善外贸商品结构以适应双边产业内贸易的快速发展。

The traditional Grubel-Lloyd equation, which is popularly used in evaluating the development of intra-industry trade, proves to be imperfect in evaluating bilateral intra-industry trade. Bergstrand equation is therefore adopted in this paper in the examination of the development of bilateral intra-industry trade between China and Japan with a purpose of analyzing the relevant decisive factors and developmental prospect. The bilateral intra-industry trade between China and Japan, through the examination, is found to be rising slowly while largely remaining stable, reflecting the comparative superiority and economic structural characteristics of the two countries respectively. The paper holds that the structure of China’s export products should be improved at both the micro and macro levels so as to adapt to the speeding up of the development of the bilateral intra-industry trade between the two countries.
