With the progress of society, our country is stepping into the peak of urbanization process. The rapid development of urbanization is inseparable from the development and utilization of land, especially the expropriation and utilization of collective land. According to the relevant provisions of the Constitution and the land management law, the state has the right to expropriate collective land according to the legal procedures for the purpose of public interest, and to compensate and resettle them. Due to the imperfection of the legal system of rural collective land expropriation in China, it is easy to lead to the abuse of administrative power and illegal land acquisition, which causes great damage to the legitimate rights and interests of landless farmers. At present, there are many legal problems in the process of rural land acquisition in our country, such as the lack of prior identification of public welfare purpose, low compensation standard, lack of corresponding supervision and relief channels, etc. This paper intends to discuss the legal problems in the process of rural collective land acquisition in China, and put forward corresponding suggestions for the improvement of rural collective land acquisition system in China.
