运用Cobb-Douglas生产函数,对1996～2005十年间我国建筑业的生产投入状况进行评估分析。分析表明,我国建筑业在这十年的发展呈良好的上升状况,建筑业总产值与增幅有显著提高,而在资本和人力投入方面的投入的增幅则呈下降的趋势,证明我国的建筑业生产效率呈上升的趋势,但上升幅度不足,对总产值贡献有限。这种计量分析方法为其他经济效率的研究提供了有益的借鉴。
Using Cobb-Douglas production function, this paper evaluates the production input of China’s construction industry during the decade of 1996-2005. The analysis shows that the development of China’s construction industry has shown a good upward trend in this decade, with the total output value and growth rate of the construction industry significantly increased while the investment in capital and manpower input has shown a declining trend. This shows that China’s construction industry Production efficiency is on the rise, but not enough to increase, contributing only to the total output value. This method of econometric analysis provides a useful reference for the study of other economic efficiency.
