中国与金砖国家产业内贸易水平测度及影响因素

通过运用改进后的G-L指数测度中国与金砖国家产业内贸易水平,并与不同发展水平国家间的产业内贸易进行对比分析,表明金砖国家产业内贸易水平显著低于发达国家,同时发展水平不同不是限制两国产业内贸易的绝对因素;测度SITC(Rev.4)分类下的中国与金砖国家0-8类产品产业内贸易水平,显示金砖国家内部不同国家、不同种类产品的产业内贸易水平具有较明显的差异性;运用灰色关联分析法计算出影响因素与产业内贸易水平的关联度,得出市场规模差异、人均收入差异、市场开放度差异、外商直接投资对产业内贸易影响程度较大。因此,应开展文化交流、发挥比较优势、提升创新能力以及有侧重地根据影响因素的作用强度进行针对性调整,以提升中国与其他金砖四国产业内贸易水平。

Measurement and Influencing Factors of Intra Industry Trade Level Between China and BRICS

By using the improved G-L index to measure the level of intra industry trade between China and BRICs,and comparing with the intra industry trade between with different development levels,it shows that the level of intra industry trade of BRICs is significantly lower than that of developed countries,and the different development levels are not the absolute factors restricting the intra industry trade between the two countries.By measuring the level of intra industry trade of 0-8 products between China and BRICs under SITC(Rev.4),it shows that there are obvious differences in the level of intra industry trade of different countries and products within BRICs.Using the grey correlation analysis method to calculate the correlation degree between the influencing factors and the level of intra industry trade,it is concluded that the differences in market size,per capita income,market openness and foreign direct investment have a greater impact on intra industry trade.Therefore,it is necessary to carry out cultural exchanges,give full play to comparative advantages,enhance innovation ability,and focus on the targeted adjustment according to the effect intensity of influencing factors,so as to improve the level of intra industry trade between China and other BRICs.
