The free flow of urban and rural production factors is not only an important part of urbanization，but also an important manifestation of the relationship between industry and agriculture. The unsmooth flow of urban and rural factors of production has always been the outstanding embodiment of urban and rural dual barriers. The one-way flow of a large number of labor，capital and means of production in rural areas to the city is an important reason for the imbalance of urban and rural development. How to realize the free flow of urban and rural factors is an important content of urban and rural integration and development，and also one of the keys to the implementation of Rural Revitalization. To realize the free flow of production factors in urban and rural areas，we need to continue to deepen the reform of the system and mechanism of urban-rural integration，and increase policy support for production factors to go to the countryside.
