中国“入世”后,中日贸易的发展与中国其他主要贸易伙伴相比有一定的差距,其占中国对外贸易总额的比重不断下降。为了深入了解中日贸易的发展变化,本文以制成品为研究对象,在国际贸易标准分类的基础上,借助贸易强度指数、互补性指数、产业内贸易指数等进行了定量分析。结果表明,双方紧密的贸易联系和较强的互补性并没有发生改变。只要能妥善处理诸多政治分歧,双方贸易增长还将有很大的潜力。 After China entered the WTO, the development of trade between China and Japan lags behind that of other major trading partners in China and its share in China’s total foreign trade has been declining. In order to know more about the development and changes of Sino-Japanese trade, this paper takes the finished product as the research object and conducts a quantitative analysis on the basis of the classification of international trade by means of trade intensity index, complementarity index and intra-industry trade index. The results show that there is no change in the close trade ties and strong complementarities between the two sides. As long as many political differences can be properly handled, there will be great potential for trade growth between the two sides.
