摘要
本文基于20多万组数据,采用修正后的Finger&Kreinin模型测度了中国与49个国家1993-2006年金属制品出口结构的相似度,以反映中国金属制品技术含量的动态变迁,并运用基于协整检验和广义最小二乘法的固定效应Panel Data模型对中国金属制品出口技术含量演进的内在动力进行实证分析。主要结论为:中国金属制品出口的技术含量呈不断上升趋势,且技术含量与发达国家日渐相似,与发展中国家日益偏离;中国金属制品技术含量与发达国家日趋一致的主要动力是出口增长,与发展中国家日益偏离的原因在于发展中国家出口品价格的增长速度快于中国;中国金属制品的自主创新能力还很弱,技术含量提升主要依赖外力。
Based on 200 thousand group data, this paper takes advantage of revised Finger ＆ Kreinin＇ s model to estimate the metalwork export similarity between China and other 49 countries from 1993 to 2006, so as to show the evolution of the technology content of Chinese metalwork. Moreover it uses fixed effect panel data model with GLS to analysis the mechanism of Chinese met- alwork＇ s evolution of the technology content. The results show： Firstly, the technology content of Chinese metalwork has been increased dominantly, and become more similar to developed countries; Secondly, increase in export is the main spur to the increase of export similarity between China and developed countries, price ascending speed exceeding China lead to the increase in export dissimilarity between China and developing countries; Thirdly, self-innovation ability in Chinese metalwork industry is very weak, the increase in the technology content are mainly rely on ＂external power＂ .
