Land is the space carrier for the existence and flow of other development factors.Activating rural land and promoting the circulation of other development factors through land management innovation is necessary to realize rural vitalization.This paper identifies the connotation of factor flow in the rural vitalization context,the action mechanism of land management innovation to boost the flow of development factors,the issues and obstacles restricting factor circulation,and the realization mechanism of the flow of development factors in rural vitalization.Based on the analytic paradigm constructed in the paper,the successful practice of promoting the flow of development factors through innovative land management in a model village is examined.The results show that:1)the unreasonable systems characterized by the land use system in rural areas are the main obstacles causing circulation issues in development factors.It is essential to engage in comprehensive reform to break down these long-lasting obstacles to the smooth flow of development factors.2)The land should play a leading role in the circulation of development factors in the background of rural vitalization;the main purpose of land management innovation is to activate the land factor,thereby promoting the circulation of other factors.3)The activated land factor will act as a‘trigger’to promote capital and technology in rural settings and use capital and technology to attract the inflow of talents and the return of migrant workers,whereby the population factor will act as a‘catalyst’for the cultivation of rural culture,bringing about the integration of various development factors.4)The innovation of land use and management,increased funding,and new technologies have brought multiple talents to Tengtou Village.The high-frequency mutual feedback between the village’s own and the external development factors resulted in its successful integration of industrial development. 展开更多
