物化技术溢出的有效性分析

Efficiency of Embodied Technology Spillovers

技术进步是国家经济发展的核心竞争力 ,国家或地区技术进步水平的提高主要依赖于该国的研发能力 (R&D)和对各种可能技术溢出的吸收 ,中国是研发资金及能力相对欠缺的发展中国家 ,对技术溢出的利用尤为重要。地区和国家间物化技术溢出的主要方式是国际贸易 ,文章用一部门、三地区的GTAP(GlobalTradeAnalysisProject)模型作为计量经济分析框架 ,讨论了吸收技术溢出方的吸收能力 (AC)和贸易双方的结构相似性 (SS)与有物化技术溢出之间的关系。结果表明 ,假定技术进步为希克斯中性技术进步 ,GTAP模型显示 :保持原有产出水平 ,技术溢出均等地减少了各项投入。

Technological progress is the key competitive ability of a society.A society's technological progress depends on it's ability of research and development (R&D) and the absorption of R&D spillovers. Since China is a developing country, which is comparatively short of R&D expenditure and activity, it is absolutely necessarily to utilize R&D spillovers. This paper analyses the relation among destination-specific AC (Absorption Capacity) , source- and destination-specific SS (Structural Similarity) and embodied technology spillovers by one-sector and three-areas GTAP models. The conclusion is:Being 'neutral' in nature, the exogenous Hicks-Neutral Technical Progress shock uniformly reduces the input requirements associated with producing a given level of output of stuff.
