【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 development and changing trend of import and export trade of China’s rosin intra-industry trade from 2001 to 2015, it is concluded that the type of intra-industry trade of rosin in China exists. 【Method】 By using various trade theoretical models such as intra-industry trade index, least square method and multiple linear regression residuals, using Mat Lab software, combined with the intra-industry trade during the study period, we measured the index of import and export data. 【Result】 After fitting, the import prices and imports of rosin did not satisfy the linear relationship, nor did they satisfy the inverse proportion. There was a certain regression relationship between the types of products and the exports and imports, and the residual value of exports and imports The difference variance is 0.001 0 and 2.769 5 respectively. The model is in good agreement with the actual one. Analyzing the GL index and marginal intra-industry trade index, it is concluded that the intra-industry trade of China’s rosin industry is a mixed intra-industry trade from 2001 to 2015 and that it is based on vertical intra-industry trade. 【Conclusion】 We should seize the competitive advantage of resource endowments and develop sustainable intra-industry trade. We should create competitive advantages of non-resource endowments, increase investment in scientific research, accelerate the development of intra-industry trade of rosin and promote the development of high-quality intra-industry trade.
