There are many studies about the surplus labor-force shift in countryside at present and the standard of the quantity relative ratio of surplus labor in countryside was summed up into 6 measures by foreign scholars: the difference of expected income in urban and rural areas and standard of employment rate in cities, the measure of international standard model, the measure of agricultural technology needs and so on. According to the theory of dual economic structure, the western economists of development economics have established dual economic model by W. A. Lewis, Fei-Rain Model, Dale W. Jorgenson Model, Population Flows Model by M. P. Tordro and so on. Based on the theory model of development economics, the domestic scholars pointed out the model of the shift on the spot, the model of the shift at off-site and the pluralist multiplex model and other models about the surplus labor in countryside. Discussing these different ideas is good for enriching the studies of rural economics in theory and promoting the development of rural economy in practice in our country.
