Abstract:People have paid adequate attention to the increasingly serious problems as the interest expression by the land-lost peasants in academic circle and they have made great fruits. Through the sorting of such fruits, we can find there exist both parallels and divergence. The former show in the causes of interest damage, interest expressions, non-institutionalized inclination of interest expression and the choice of their action. And the latter mainly lies in how to reconstruct the effective and well-ordered interest-expression mechanism while there exists difference in perspectives of their study. The author of this paper suggests that we pay attention to the motivation mechanism of action-chosen strategies by land-lost peasants at a micro level. And at a macro one, we focus on the construction of relevant policies in order to contribute to the transformation from the non-institutionalized interest expression to the institutionalized one by land-lost peasants.
