中文摘要：

外部技术获取是技术进步的推动力之一，对我国制造业技术创新具有重要影响。本文在将外部技术获取分为技术引进和技术溢出两种方式的基础上，利用2005～2010年我国29个制造业行业的面板数据，从创新投入产出视角研究了外部技术获取对我国制造业技术创新的影响，并考察了技术创新投入的中介作用。实证结果表明：国内技术购买对我国制造业技术创新投入具有促进作用，而国外技术引进和FDI技术溢出具有不利的影响；国外技术引进和国内技术购买对我国制造业技术创新产出具有正向的影响，而FDI技术溢出具有负向的影响；技术创新投入在国内技术购买影响我国制造业技术创新产出的过程中起到了完全中介作用，而在FDI技术溢出影响我国制造业专利中请量的过程中起到了部分中介作用。

英文摘要：

External technology acquisition is one of the impeaums for technology progress, and it has great impact on the technologl- cal innovation d manufacturing enterprises in China. The external technology accluisition in this research is divided into technology import and technology splllover. Based on the pane] data of the 29 manufacturing industries in China from 2005 ~ 2010, the impact of external techn01ogy acquisition on the technological innovation was studied from the view of innovation input and output, and the intermediation ef- fect of technological innovation input was also put into consideration. The empirical results show that the domestic technology purchase has positive effect on the technological input of manufacturing industries in China, while the foreign t~hnology import and the technology spillover of FDI has negative effect. The foreign technology import and domestic technology purchase has positive effect on the technological output of Chinese manufactm＇~ industries, while the technology spillover of FI）I has negative effect; the technological innovation input plays a complete mediating role in the process that the domestic technology purchase influence the technological innovation output. Howev- er, it has partial mediation impact in the process that the FDI teclmological spillover influences the patent applications of Chinese manufac- indusaies.
