笔者结合收益成本理论及托达罗模型,在对农民预期迁移收益和成本分析的基础上,通过调研数据,分别对＂就地＂和＂异地＂两种迁移方式以及迁移前后的收益进行对比分析。结论显示：第一,农村剩余劳动力就地迁移和异地迁移的最低期望月薪差值远远大于异地迁移成本;第二,农民对就地迁移和异地迁移的最低期望月收入分别是农民在农村剔除务工收入后人均月收入的3.42倍和4.80倍,这两个比例数值即是本文寻求的焦点——农村剩余劳动力迁移的充要条件,并且该比例数值可能会随着不同地区农村经济水平的提高而减小。
筆者結閤收益成本理論及託達囉模型,在對農民預期遷移收益和成本分析的基礎上,通過調研數據,分彆對＂就地＂和＂異地＂兩種遷移方式以及遷移前後的收益進行對比分析。結論顯示：第一,農村剩餘勞動力就地遷移和異地遷移的最低期望月薪差值遠遠大于異地遷移成本;第二,農民對就地遷移和異地遷移的最低期望月收入分彆是農民在農村剔除務工收入後人均月收入的3.42倍和4.80倍,這兩箇比例數值即是本文尋求的焦點——農村剩餘勞動力遷移的充要條件,併且該比例數值可能會隨著不同地區農村經濟水平的提高而減小。

In combination with the theory of benefit-cost and Todaro Model,on the basis of an analysis of farmers＇expectant benefit and cost for the migration,through studying the collected data,the authors made a comparative analysis of the ＂local migration＂ and ＂long-distance migration＂ and their income before and after the two different ways of migration.The conclusions are as follows：firstly,the difference between the lowest expected incomes for ＂local migration＂ and ＂long-distance migration＂ is much more than the cost of ＂long-distance migration＂ ;secondly,farmers＇ lowest expected monthly incomes for ＂local migration＂ and ＂long-distance migration＂ are respectively 3.42 and 4.80 times their monthly income per capita in the village（excluding the income gained as migrant workers）.Those two ratios are just the focus of this paper——the necessary and sufficient conditions for the migration of rural surplus labor,and the two ratios may decrease depending on the economic level of different rural areas.
