Abstract: By developing a model of institutional discriminatory policy for diversified benefited groups,we argue that institutional return and cost is asymmetric and the asymmetry comes from the institutional structure.Furthermore,as the institutional cost is to be transferred layer by layer,an unlimited pursuit of maximizing returns by the institutional dominant will not only lead to ever widening gaps between the rich and the poor and to social unrest,but also to negative feedback of ecology and environment,which will severely challenge the security and sustainability of human beings.

Key words: institutional being poor, institutional cost transfer, negative feedback, human security

摘要： 本文通过构建多元利益结构下的政策歧视模型,指出制度成本与制度收益的不对称关系具有内生性,这是致贫制度的核心特征。本文进一步指出,由于制度成本的层层转嫁,主导者无约束地追求收益最大化,不仅将导致当代社会贫富分化加剧和社会动荡,还将招致自然生态和资源、环境的严重负反馈,给人类自身的可持续性带来严峻挑战。
