Threshold of Migrant Worker's Wage Level and Statistical Error in Urban -- Rural Income Gap.

This is a study of the influence of urbanization lag on the gap of urban -- rural income. The theoretical model of it demonstrates that the increase in migrant workers wage has reached a threshold, which could contribute to narrow the gap. We find some missing error in the statistical data about the wages of rural migrant workers in China's Statistics Yearbook. The phenomenon of increase of migrant workers together with the widening of urban -- rural income gap is the result of both the statistical error and lower migrant workers wage in China. Our positive analysis proves that rural migrant workers wage has reached a threshold value, which could play a active role to narrow the urban -- rural income gap. [ABSTRACT FROM AUTHOR]
