中间产品进口对中国高技术产品出口技术含量的影响

Import of Intermediate Products Impact on Exports Technology of China's High-tech Products

在新贸易理论的指导下,国际贸易模式不断发展与创新,产品内贸易盛行。本文根据2000—2013年高技术产品五大行业面板数据,基于豪斯曼构建的产品出口复杂度指标对中国高技术产品的出口技术含量进行测度,得出这期间其出口技术含量呈现逐年上升的趋势。本文引入虚拟变量,实证分析FDI、R&D及中间产品进口五大行业对其出口技术含量的影响。结果表明,总体来说FDI、R&D和中间产品进口均有助于提升产品的出口技术含量;但对细分行业来说,中间产品进口与出口技术含量的关系是不确定的,需要区分不同类型的产品,电子及通信设备、电子计算机及办公设备和医疗设备及仪器仪表三类产品的中间产品进口会促进高技术产品出口技术含量的提升,而医药和航空航天器产品的中间产品进口则会阻碍其出口技术含量的提升。

Under the guidance of the new trade theory,the modes of international trade are developing and in-novating,and trades in products are popular.In this paper,according to the five industry panel data from 2000 to 2013,and export complexity index based on Hausmann,it is concluded that the export technical content showed a trend of rising year by year.This paper introduces virtual variables,analyzing FDI,R＆amp;D and import of intermediate products,and the results show that the overall FDI,R＆amp;D and the import of intermediate products can promote the export of the product technology content,but for niche business,the import and export of intermediate product tech-nology content are not quite related,which need to distinguish among different types of products.Importing in terme-diate products of electronic and communication equipment,computers and office equipment,and medical equipment and instrumentation can promote the export of high-tech products,while importing intermediate products of pharma-ceutical and aerial will hinder the export technology level.
