基于生产函数模型的农民工对经济增长贡献率的测量

Measurement of the Rural Worker's Contribution Rate to the Economic Growth Based on Production Function Model

在充分考虑农民工和城市非农产业工人的生产率差异的基础上,本文利用"新"经济增长理论中的生产函数模型来分析农民工对经济增长的贡献,并给出了贡献率和年平均贡献率的定义及测算公式,最后利用我国1995 -2005年的数据进行了实证分析。实证结果表明,在考察期内,农民工在我国经济增长的平均贡献率达到13.2%。

With consideration of the gap between rural workers' productivity and oppidan workers',the rural worker's contribution rate to the economic growth is analyzed by using the production function model in new economic growth theory.Then,the definitions and formulations of contribution rate and average contribution rate are also given. The empirical illustration proved,during 1995 to 2005,the average contribution rate of rural workers to Chinese economic growth is 13.2%.
