The article discusses the current situation and improvement project of land expropriation in China, focusing on the process of land acquisition. The land acquisition system in China involves converting rural collective land into state-owned land for public interest, compensating rural collectives and farmers. However, the system faces challenges such as lack of clear legislation, criteria for determining public interest, and inadequate procedures for compensation and oversight. To address these issues, establishing clear standards, enhancing legislation, limiting government rights, protecting farmers' interests, defining criteria for public interest, and improving procedures for land acquisition, compensation, and oversight are essential.
