"Daigeng Farmers" is the result of mobility of rural labor forces.It is estimated that there was 750,000 "Daigeng Farmers" till 2004,which accounted for 9.46% of the migrant population in the countryside.Taking "Daigeng Farmers" in Tiechang Village of Huizhou,Guangdong Province for example,this paper compared the cost and profit of three employment methods of rural labor forces,there are "Daigeng Farmers",farming at home and migrant workers,and found that "Daigeng Farmers" at least is the second choice of mobility of rural labor forces.For those with older age,lack in other skills except farming,"Daigeng Farmers" is the best choice.The mobility of rural labor forces connected by incentive of profits and short-term land leasing contract enables the land resources to be optimized and farmers to increase their incomes;on the other hand,land may be overused by this mobility.Therefore,the governments should guide and regulate land circulation based on clear land property and create suitable conditions for the integration of "Daigeng Farmers" into the local society.
