摘要：“公共利益”条款主要规定在我国宪法修正案中，这些条款是针对农村集体土地征收和国有土地征用问题而设置的，重点是对被征地者的补偿与安置。但是宪法和普通法律法规对公共利益的界定模糊甚至有很多矛盾之处，从而导致在实践中出现了很多涉公共利益的侵权问题。因此，本文从公共利益界定问题着手，结合了近年来土地征收、征用领域发生的一些与公共利益问题相关的典型案例，说明了公共利益相关制度缺失给经济社会发展和各利益主体利益的实现所带来的不良影响。然后从现实意义和法律意义两个方面进一步说明了明确化和合宪化的公共利益对于我国经济社会发展的积极意义。最后，从公共利益实施过程中相关机制的缺失角度出发，进而提出应该对因公共利益侵权导致的损失设立救济途径等配套制度，特别是建立征地听证制度让各利益相关方参与其中，通过各方对各自利益选择达成对“公共利益”认识上的共识，从而达到公共利益与个人利益在目标和结果上的统一。
