摘要/Abstract

摘要： 本文在生产理论的基础上,将国家特征作为生产效率的影响因素引入传统的随机生产边界模型,建立了基于柯布-道格拉斯生产函数的二个方程随机生产边界模型,实证检验了我国1997-2010年IT资本对经济增长及生产效率的影响。研究发现:IT资本对我国经济增长和生产效率具有显著的促进作用,从国家层面证明了"生产率悖论"并不是全球化的现象;IT资本弱化了物质资本对于经济增长的贡献,强化了人力资本对于经济增长的贡献;国家特征促进了生产效率的提高,但是并没有促进IT价值;我国经济在发展过程中呈现规模报酬递减。基于实证研究结果,提出了实现我国IT投资价值的相关政策建议。

Abstract: Based on the production theory, as influential factors of productivity, the national characteristics are introducing into traditional model of stochastic production frontier and based on Cobb-Douglas production function, the two-equation stochastic production frontier model is constructed to investigate the contribution of Information Technology (IT) capital toward economic growth and production efficiency during the period of 1996 to 2007 in China. The main conclusions are as follows: the IT capital has a positive impact on economic growth and production efficiency, the productivity paradox is not a phenomenon of globalization is verified at the national level; the IT capital weakens the contributions of physical capital toward economic growth, and strengthens the contributions of human capital toward economic growth; the national characteristics improve production efficiency, however do not realize the value of IT investment; the phenomenon of returns to scale decrease occurs in china. Based on the results of empirical examination, some suggestions for promoting IT investment value in China are proposed.

Key words: information technology value, productivity paradox, stochastic production frontier, Cobb-Douglas production function, developing country
