基于投入产出模型的中日进出口产品结构合理性比较研究

Study on the Comparison of Import-Export Rational Validity between China and Japan Based On Input-Output Model

从进出口部门的角度出发,通过构建进出口产品结构的合理性评价机制和评价指标,运用中日两国的投入产出表,对中日两国进出口产品结构的合理性进行分析和比较。结论如下:中国进出口产品结构的合理性要优于日本进出口产品结构的合理性,中国的进口产品合理度指数高于日本的进口产品合理度指数,而出口产品的合理度指数却低于日本。最后分析了产生这些差距的原因,并得出了重要的政策启示。

With the purpose of partly explaining the reasons that cause the gap of growth rates between China and Japan, this paper dedicates to making a comparison of the rationality of two countries＇ import and export industry. By building a new rationality assessment system, which includes a rationality assess- ment system of import and export structure and a measurement of rational validi- ty of import and export, this paper calculates and analyses the data from Chi- nese 2002, 2007 input-output tables and Japanese 2001, 2005 input-output tables and it gets the following conclusions： China has superior industry structures of import and export to Japan and also has a higher rational validity of import in- dustry. However, its rational validity of export industry is lower than that of Ja- pan. Finally, this paper explains the reasons causing these differences and puts forward corresponding strategies and advice.
