中文摘要：

土地征用的制度缺陷是引发农村征地矛盾冲突的主要约束条件。在动态变化的政治机遇和政治限制中,政府征地与农民维权的利益博弈过程必然会产生征地矛盾;借助利益认同与身份认同的双重叠加产生的心理推动力,失地农民通过资源动员和社会建构过程,使征地产生的权益损害不断被社会公众关注;在经济、社会及政治多方面诱因作用下,随着某种导火索事件的出现,又会促使征地矛盾升级演化为对抗性冲突。

英文摘要：

The institutional defect in expropriating rural land is the leading binding condition to cause contradictions and conflicts in the practice.Under the actively-changing political opportunity and restraint,contradictions must occur between government＇s expropriating land and farmers＇ preserving their right.Driven by a double psychological motivation of identity agreement and interest agreement,the land-lost farmers manage to bring the damage of their interests in expropriating land to public concern by mobilizing resources and constituting society.Under the effect of economic,social and political factors,a contradiction of expropriating land is likely to upgrade into a confronting conflict when a trigger event happens.
