本文根据2002年和2007年中国投入产出表的数据,运用投入产出技术,在考虑到产业间部门生产关联的基础上,对出口贸易对我国电子信息产业的影响进行量化分析.实证结果表明:我国电子信息产业的实际出口依存度远大于出口率所显示的程度;电子元器件制造业是产业出口贸易中高额增加值流失的主要部门;电子信息产业各部门出口对GDP的贡献效率都低于其他产业,总体有下降趋势,而且下降速度比其他产业快.本文的政策结论在于,政府不应过快促进电子信息产品的出口,而更应加大力度提高产业的核心技术水平以减少中间品的进口.“,”Based on the data from Input- Output table of China in 2002 and 2007, this paper uses Input- Output technology to make a quantitative analysis a- bout the effects of export trade to the Electronic Information Industry while consid- ering the problem of Production Association among the departments in this indus- try. The results of index show that the real degree of Electronic Information Indus- try~ s export dependence is far beyond the export rate could show; the Electronic Components Manufacturing is the main source of the loss of the value added; The political suggestion of this paper is that the government should first emphasize on enhancing the kernel technical level of the Electronic Information Industry to reduce the import amount of the intermediate goods, but not rush to promote the export of this industry.
