Abstract: 【Objective】By revealing the import and export trade development and changing trends through year 2001 to 2015, 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 MatLab 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 were 0.001 0 and 2.769 5, which the model and the actual matched each other. Through analyzing the GL and marginal intra-industry 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.
