Abstract: How do rural collective organizations lead land trusteeship? How can land trusteeship grow rural collective economies? Existing studies have not yet provided a clear answer. The study takes Gu Village in Shanxi as a sample, and constructs a "theoretical model of land trusteeship to strengthen rural collective economy" through grounded research. The study found that real needs, endogenous motivation, and external drives are the core elements of rural collective organizations leading land trusteeship. The real demand is attributed to the depression of rural collective economy, the withering of agricultural production, and the call of the times to solve the "issues of agriculture, farmer and rural area"; The endogenous drive is mainly stimulated by the leader’s ability and sense of morality, the unity and cooperation of the committees and teams, the leadership of the party organization, and the professional cooperatives; The external driving force is mainly driven by the government’s attention and overall planning, policy navigation and mechanism guarantee, human resources, equipment and technology empowerment, and local advantageous industry support, etc. Rural collective organizations leading land trusteeship are the key to growing the rural collective economy. The study aims to explore the theoretical and practical problems of taking rural collective organizations as the main actors of land trusteeship and developing and expanding rural collective economy, so as to provide reference for how to do a good job of this big article on land and realize common prosperity in different places.
