立足于“机会成本”与“外部效应”等经济学概念，试图从当地人的视角出发。来展现代耕农生存的被动境况，揭示代耕农身处当地人、基层政府以及工厂主的理性选择视野之外，后者唯利的行动取向中，没有道德的维度；机会成本发生改变的同时，代耕农也从“嵌入”走向了“脱嵌”，其社会经济层面的生存境况也从外部正效应走向了外部负效应。

Economic concepts like ＂opportunity cost＂ and ＂external effect＂ are borrowed to reveal the survival predicament of modern substitute peasants from the perspective of local residents, showing that modern substitute peasants stand beyond the rational choices made by the local residents, government and factory owners, in whose profit-first behaviors the bottom-line of morality has been lost. Substitute peasants have gone from ＂integration＂ to ＂rejection＂ when opportunity cost changes. From the social and economic perspective, their survival predicament has changed from positive external effect to negative one.
