技术进步对建筑业劳动生产率的影响分析

The Impact of Technical Progress on Labor Productivity in China's Construction Industry

以经典的柯布—道格拉斯函数和索洛经济增长模型为基础,建立劳动生产率增长函数模型,并以建筑业1995—2009年的统计数据为样本,分析技术进步和资本深化对劳动生产率增长的影响程度。结果显示:1995—2009年,技术进步对我国建筑业劳动生产率的增长起主要推动作用;建筑业劳动生产率实际年均增长率较低,促进建筑业持续快速发展需要进一步提升技术进步水平。

The function model measuring labor productivity growth is proposed based on the Cobb Douglas function and Solow growth model.The statistical data of construction industry from 1995 to 2009 are used to calculate the contribution to the growth of labor productivity,which is made by the technology improvement and capital investment.The results show that the technology improvement plays a major role for the growth of labor productivity in construction industry.Facing the relatively low growth of labor productivity of Chinese construction industry,the level of technical improvement need to be enhanced in future to promote the healthy and rapid development of the industry.
