Abstract:The system of land expropriation is a legal system instituted for the development of social public service by various countries around the world. What crucially matters is to construct and perfect such system. Employing contrast and comparison with foreign countries or areas, and drawing on their experience, what can be grasped is that it is indispensible to embrace a new idea for the sake of improvement of the land expropriation system. Specifically, such development and amelioration cannot be achieved through the clichéd ideas like supersession of private right with administrative idea or coercive expropriation by administrative power; rather, they are predicated upon whether these concerns can properly be resolved, which comprehend for instance, definitions of the public interest, the establishment of equitable compensatory system, the perfection and standardization of the procedure, the organization of resettlement of the expropriated etc.
