中国松香产业内贸易类型评价

Evaluation of the intra-industry trade type of Chinese rosin

【目的】通过揭示2001—2015年以来中国松香产业内贸易的进出口贸易发展和变动趋势得出,中国松香产业内贸易存在的类型。【方法】采用各类产业内贸易指数等贸易理论模型,以及最小二乘法、多元线性回归残差等方法,运用Mat Lab软件,结合研究时段的产业内贸易,对进出口数据进行指标测算。【结果】经拟合,中国松香进口价和进口量之间不满足线性关系,也不满足反比例关系;产品种类与出口额、进口额之间有一定的回归关系,出口额和进口额的残差方差分别为0.001 0和2.769 5,模型与实际较吻合。分析GL指数和边际产业内贸易指数,得出2001—2015年中国松香产业内贸易类型为混合型产业内贸易,并且是以垂直型产业内贸易为主的贸易方式。【结论】应抓住资源禀赋的竞争优势发展可持续的产业内贸易;要创造非资源禀赋的竞争优势,加大科研投入,加速发展松香产业内贸易,促进高质量产业内贸易的发展。

【Objective】By revealing the import and export trade development and changing trends through year 2001 to2015,we can determine and evaluate the intra-industry trade types of Chinese rosin.【Methods】We used various types of intra-industry trade indices such as the trade theory model,the least squares method,the multiple linear regression residual mathematical model and the Mat Lab software,combined with calculations from the year 2001 to 2015 of intra-industry trade import and export data index.【Results】After fitting,Chinese rosin import price and import quantities does not meet the linear relationship between each other,and also does not meet the inverse proportion.There is a certain regression relationship among product variety,exports and imports,the residual variances of exports and imports were0.001 0 and 2.769 5,which the model and the actual matched each other.Through analyzing the GL and marginal intraindustry trade index,we concluded that through year 2001 to 2015,the Chinese rosin intra-industry trade type was hybrid intra-industry trade,and the vertical intra-industry trade was the main way of intra-industry trade.【Conclusion】We should grasp the competitive advantage of the resources endowment,develop the sustainable intra-industry trade,create the competitive advantage of resources endowment,increase investment in scientific research,to accelerate the development of rosin intra-industry trade and promote the development of intra-industry trade with high quality.
