跨国生产函数之普适性的实证分析

本文运用组数据同积检验法考察覆盖22个国家、跨度从1971年至1990年的相关宏观经济时间序列变量。实证分析显示产出与投入之间同积关系的存在与否——不论这种同积关系是由二要素还是由三要素柯布—道榕拉斯生产函数来代表,关键取决于各国经济发展的独特初始特征和独特时间趋势特征是否被考虑到。我们的发现表明不存在适用于所有国家的通用生产函数,这就对那些在经济发展之国家比较研究中简单假设存在通用生产函数的做法提出了强烈质疑。

AN EMPIRICAL INQUIRY ON THE PRESENCE OF UNIFORM PRODUCTION FUNCTIONS ACROSS COUNTRIES

This paper uses panel cointegration methodology to examine alternative cross-country produc- tion function specifications for a panel of 22 developed countries over the period 1971 to 1990.The presence of a cointegrating relationship between output and inputs,represented by either a two-factor Cobb-Douglas pro- duction function or a three-factor Cobb-Douglas type,depends crucially on whether country-specific intercepts and country-specific time trends are accounted for.Our findings basically imply that ther...
