中韩钢铁产业内贸易及影响因素研究

An Empirical Analysis of Steel Intra-Industry Trade between China and South Korea and its Determinants

针对中韩钢铁产业的总产业内贸易、水平型产业内贸易和垂直型产业内贸易的发展和特征进行了实证研究,发现在汇总水平上水平型产业内贸易是中韩钢铁产业内贸易的主要形式,而具体贸易产品组的产业内贸易模式却以垂直型产业内贸易为主。对中韩钢铁产业内贸易的影响因素分析表明,总产业内贸易和水平型产业内贸易与平均市场规模、人均国民收入差距、中国实际利用韩国的直接投资额以及中韩钢铁产业的贸易总额均有长期稳定的正相关关系,而与中国钢铁产业的规模经济以及中韩两国钢铁产业的技术差距负相关;垂直型产业内贸易除了与规模经济的相关关系为负之外,与其他影响因素的协整关系均是正向的。这种研究结论对我们的政策制订有一定启示作用。

Through analyzing the development and characteristics of whole, horizontal and vertical intra-industry trade of steel between China and South Korea, it has been found in this article that the main intra-industry trade style on the whole industry level is horizontal intra-industry trade, and on the concrete product groups vertical intra- industry trade is the mainly style of intra-industry trade. Among the determinants, average market scale, difference of GNI per capital, real FDI from South Korea to China and the total steel trade between these two countries have positive effects on the whole and horizontal intra-industry trade, while the effects of scale economy and difference of technology are negative. On vertical intra-industry trade, the effect of scale economy is negative too, but all the other determinants can promote vertical intra-industry trade positively. This kind of conclusion is illuminating for us to make relative measures.
