出口技术结构的测度方法包括Lall(2000)的技术分类方法、出口复杂度指数及其修正指数、出口相似性指数等,一些研究采用这些不同方法考察了中国出口技术结构,但因为度量方法、研究角度的差异,从而得到了不一致的结论。也有文献考察了出口技术结构的影响因素,但在变量选取、模型设定以及实证方法方面有待进一步发展和完善。本文研究对于合理度量中国出口技术水平、分析其动态变迁及影响因素具有指导价值,对于制定促进中国出口贸易结构升级的政策措施具有借鉴意义。
The measurements about the technological structure of exports mainly include the technological classification in Lall(2000), the sophistication index of exports and the adjusted indices, the export similarity index etc. With these methods many studies analyze the technological structure of China’s exports. These studies, however, approach the different conclusions. The determinants of the technical structure of export are also explored by many existing studies, which need to be improved in the variable choice, the model specification and the empirical methodology. This study is helpful to measure the technological level of Chinese export and to explore its dynamic change and its determinants. It is also obviously worth referencing for policy formulation to upgrade China’s export structure.
