中国出口结构在优化吗--基于产品内分类的视角

Should We Optimise China's Export Structure?——Based on Classification within-product

同一产品内部的不同种类间存在较大价格差异。根据价格高低将同一产品可划分为三类,即高端产品、中端产品与低端产品。同一产品出口中高端产品比重增加意味着出口结构优化。基于此,利用HS六分位贸易数据,本文重新审视了中国出口结构,认为;中国出口产品中70%以上为中低端产品,而且有增加趋势;中国与经合组织国家出口相似度有减少趋势;产品技术复杂度越高,中国出口产品越处于低端位置;因此,中国出口结构水平较低,低于中国经济的发展水平,提升其出口结构水平具有较大的空间。

There are great price differences among varieties within a product. Based on the price differences, we classify products into three groups： high quality groups, middle quality groups and low quality groups. The more ratio of high quality groups, the better export structure. From this perspective, with HS 6 digit level data, we reanalyses China＇ s export structure. The conclusions are： 70% of China＇ s export are of low or middle quality , with no trend of decreasing; the similarity of China＇ s and OECD＇ s export structure decreases; therefore , China＇ s export structure is not good, with no trend being better; comparing with China＇ s development level, China＇ s export structure is under- development.
