摘　　要：基于增长理论的分析框架,从要素投入和技术溢出两个角度出发,本文把信息化对经济增长的作用界定为增长效应和效率效应,继而探讨了两种效应对经济作用的机制与联系。在利用2001～2005年的面板数据进行经验分析后,本文发现,中国信息化发展对经济增长的作用是积极的,但是对于经济增长技术效率的影响并不明显;无论是作为要素投入的因素,还是作为效率影响因素,区域信息化的差异都能解释不同地区之间经济差距;相对于信息化要素投入的增长效应,信息化的技术外溢更能反映信息化在经济中的重要作用。本文的政策含义在于,推进信息化建设不仅要加强信息产业的发展,发挥信息产业在国民经济中的带动作用,而且重在发挥信息化在经济中的技术溢出和资源配置作用,以此来提升经济发展的质量。Based on the analysis framework of growth theory, the role of informatization on the economic growth is defined as the growth effects and the efficiency effects according to the two angles of factor inputs and technology spillovers and it is discussed in the mechanisms and linkages of the two effects in the paper. After the empirical analysis of using the panel data of 2001 - 2005, the paper find that the development-of China ＂s informatization is positive to the role of economic growth, but the technical efficiency is not obvious; either as a factor in factor inputs, or as the efficiency factors, the difference of information can explain the gap of regional economic disparities; relative to the growth effects of informatization, the technology spillo^ver effects are more important than growth effects in the development of economy. The policy implication of this paper is that prompting the informatization construction is not only to strengthen the development of information industry, to urge the leading role in the national economy, but also to put forward to the role of technology spillover and resource allocation in order to improve quality of economic development.
