技术引进与我国高技术产业升级关系的实证研究

The Empirical Analysis on the Relationship between Technology Import and High-tech Industries' Upgrading in China

在使用因子分析方法综合测度高技术产业升级指标基础上,利用我国三大经济区域2004—2012年期间高技术产业五大行业的面板数据,实证研究产业种类属性和产业所处地区变量在高技术产业技术引进和高技术产业升级之间的调节关系。研究发现技术引进总体上促进我国高科技产业升级,但是对产业升级的实际效果取决于高技术产业所属的具体产业属性以及高科技产业所处的具体地域位置。技术引进对医疗仪器设备及仪器仪表制造业产业升级效果最佳,技术引进对电子及通讯设备,航空航天器和医药制造业的产业升级效果不显著。技术引进对中部地区的高技术产业升级效果最佳,西部和东部地区效果次之。技术引进对高技术产业升级的效果在东部地区体现了经济学"边际报酬递减"效应。最后根据实证研究的结果,提出相应对策建议。

Using panel data from 2004 to 2012 of five sub - industries in high technology industry and the data of three e- conomic regions of our country, based on factor analysis method to measure the degree of high technology industrial struc- ture upgrading, this paper empirically analyzes the mediating effect of specific type of high technology industry and the me- diating effect of high technology geography location on the relationship between technology import and high technology in- dustries＇ upgrading. This paper finds that the technology technology import has significantly advanced the high - tech in- dustries＇ upgrading. The real accurate effect of the advance is depending on the specific high - tech industry＇ s type and its geography location. Empirical analysis shows that the medical equipment and instrumentation manufacturing industry＇ s upgrading are significantly advanced by the technology import, but the electron and communication equipment, aviation spacecraft, pharmaceutical manufacturing industry＇ s upgrading are not significantly advanced. The effects of the technolo- gy import on the high - teeh industries＇ upgrading ranks first in middle China, followed by west China and East China. The effects of the technology import on the high - tech industries＇ upgrading present the decreasing of marginal revenue in east China. Based on the empirical result, this paper puts forwards some suggestions for Chinese high - tech firms.
