新兴七国进口贸易技术结构的度量及比较研究

Measurement and Comparison on the Technique Structure of Import Trade of Seven Emerging Economies

基于细分的产品贸易数据,采用技术水平分类方法,构建质量调整的进口技术含量指标,度量和比较1996～2010年新兴七国(E7)的进口贸易技术结构。研究表明,样本期间中国以进口中、高技术制成品为主,资源性和初级产品进口比重较低;印度和印度尼西亚主要进口中等技术制成品、初级和资源性产品,其他四国以进口中技术制成品为主;从整体的进口技术含量而言,中国和巴西处在新兴七国前列,俄罗斯和印度尼西亚处于新兴七国之末。我国应积极扩大中间产品、关键设备和零部件以及短缺资源产品的进口,优化进口贸易结构。

Based on the disaggregated trade data, this paper adopts the technological classification standards and constructs the quality-adjusted technology content index to measure and compare the import technological structure of seven emerging countries（ET） during the period of 199642010. The results show that China mainly imports medium and high technology manufactured goods and that the proportion of resource and primary goods imported was much lower. India and Indonesia are major importer of medi- um technology manufactured goods, primary and resource goods while the other four countries are major importer of medium technology manufactured goods. According to the overall level of technology contents, China and Brazil are at the forefront of the seven emerging countries while Russian and Indonesia are at the other end. China should expand the import of intermediate goods, key equipment and components, and scarce resource goods to optimize the structure of import.
