中文摘要：
形式多样的技术获取模式大幅度提升了我国企业的技术能力水平,显著影响企业的创新产出。为明确技术进步在技术获取模式与创新产出关系中的角色定位,以技术进步为中介变量,技术获取模式为前置变量,使用动态面板数据模型和中介效应检验模型搜寻和挖掘影响企业创新产出的逻辑路径。结果显示,全国层面上的技术进步在各种技术获取模式与创新产出关系中的中介效应均显著,技术进步在国外技术引进与创新产出关系中的中介效应占总效应比重最大;区域层面上的技术进步中介效应存在区域异质性,在东部地区主要在以国外技术引进为前置变量的技术创新过程中,在中部地区则主要在以国内技术购买为前置变量的技术创新过程中显著,但在西部地区均不显著。
英文摘要：
Various forms of technology acquisition dramatically improve the technological level of Chinese enterprises and significantly affect the innovation output. In order to clarify the role of technological progress, technology progress was defined as mediator, technology acquisition was defined as antecedent. We searched the logical path of promotion of innovation output based on GMM and the results showed that the mediating effect of technological advances between technology acquisition and innovation output is significant on the national level in China. The proportion of mediating effect of technological progress in the total effect is maximum between introduction of foreign technology and innovation output. But regional heterogeneity is widespread in different regions. The mediating effect of technological advances is significant in innovation process in the eastern region of China when introduction of foreign technology is the antecedent. And the mediating effect of technological advances is significant in innovation process in the central region of China when purchase of domestic technology is the antecedent. But the mediating effect of technological advances is not significant in innovation process in the western region of China when any forms of technology acquisition is the antecedent.
