摘　　要：利用省级面板数据,采用多元回归模型和固定效应分析方法,实证检验进口货物中隐含的国外研发资本与国内产业效率的关系。结果显示,一是中国能够从进口贸易中获得技术正外部性,从而显著改善全要素生产率状况;二是在东中西部地区的溢出效果表现出明显的差异,东部效果最弱,中部反应强烈,西部目前只能在来源国溢出渠道下有显著效果。因此,我国应积极扩大进口,优化进口结构,各地区要因地制宜,分类施策,对于东部要加大自身研发投入,鼓励自主创新和吸引的进口技术正外部性相结合,西部地区则应以完善进口贸易渠道和平台,推进进口贸易发展和引进外资为侧重点。With the continuous deepening of reform and opening up in China,the policy orientation and related opinions on accelerating the development of import trade have been incessantly put forward.Based on the provincial panel data,this paper empirically test the relationship between foreign R&D capital implied in imported goods and domestic industrial efficiency.The results show that.(1)China can obtain positive externalities from the import trade,which significantly improve the total factor productivity.(2)The spillover effect showed obvious differencesin different regions.The eastern effect was the weakest,and the central reaction was strong,while the western region can only have a significant effect under a single channel.Therefore,China needs to actively expand imports and all regions should categorize policies.For the eastern region,it is necessary to encourage independent innovation and attracting imported technologies to combine externalities,while the western region should focus more on improving import trade channels and platforms.
