中美双边产业内贸易及影响因素实证研究

An Empirical Analysis of the Intra-industry Trade between China and USA and its Influencing Factors

利用G-L指数对1988～2008年中美贸易数据的分析结果显示:产业内贸易已成为两国贸易的重要组成部分,其中制成品特别是SITC 5+7类资本或技术密集型制成品的产业内贸易特征尤为明显。进一步分析表明,中美产业内贸易比重的提升主要得益于垂直型产业内贸易的发展,且中国在中美垂直型产业内贸易中整体居于贸易劣势地位。对中美产业内贸易影响因素的回归结果显示:中美市场规模及其差异,以及外商对华直接投资与中美产业内贸易正相关,而中美人均GDP差异与中美产业内贸易负相关。

This paper uses the Grubel-Lloyd index to analyze the trading data from 1988 to 2008 between China and USA. The results show that： the proportion of intra-industry trade has risen quickly, especially for the manufactured product; the vertical intra-industry trade accounts for the main proportion of intra-industry trade between China and USA, and China takes the inferior position of the vertical intra-industry trade. The regression analysis result shows that： the difference of GDP between China and USA, the size of market and the direct investment flowed in China have a positive effect on the intra-industry trade between China and USA, and the differences of per capita GDP between China and USA. have a negative effect on it.
