中国城市化进程中农民工对经济产出的贡献与收益分享

Contribution of Migrant Workers to Economic Growth and the Fruits They Shared in the Process of Urbanization

在城市化进程中,农民工群体已经成为中国城市第二、三产业劳动力的重要组成部分。文章充分考虑了农民工与城镇职工在劳动生产率和劳动强度上的差异,运用柯布-道格拉斯生产函数分析1991～2010年农民工群体对中国非农经济产出的贡献率及其收入水平,得出的基本结论是:农民工对我国非农经济产出的贡献率平均为16.37%,其对中国国民经济增长做出了重要贡献,相应地,农民工群体的收入水平相对于其对非农经济产出的贡献比城镇职工偏低。城镇职工对非农经济产出的贡献是农民工的1.63倍,然而城镇职工收入平均是农民工收入的3.43倍。文章的研究结论为中国"十二五"期间新一轮扩大内需政策提供了新的思路。

In the process of urbanization, migrant workers have become a crucial part of the workforce of secondary and tertiary industries in Chinese urban areas. This paper examines the difference in labor productivity and intensity between migrant workers and urban workers and uses the Cobb-Douglas production function to analyze migrant workers＇ contribution to China＇s GDP as well as their income level. The paper concludes that migrant workers have made a significant contribution to national economic growth, with the average contribution accounting for 16. 37% of China＇s GDP, and that urban workers＇ contribution to GDP is 1.63 times that of migrant workers, but urban workers＇ average income is 3.43 times that of migrant workers. The paper analyzes the reasons for this.
