Abstract:

In recent years， the urban construction land quota transition policy has been used to solve the crowding effect and provide funds for Rural Revitalization. The main content of this policy is to allow the regions that lack the construction land quota to purchase the construction land quota from the backward regions with the surplus. However， this policy has produced certain negative effects while providing land for construction in developed cities and financial support for backward areas. How to promote regional development and improve residents' welfare at the same time requires a scientific evaluation of the transfer strategy of urban construction land quota. A quantitative spatial general equilibrium model of urban system is constructed， including production， consumption and government departments， urban construction land is internalized， by considering the local governments to maximize the objective function of the problem， the optimal transfer strategy of urban construction land quota for local government is solved， the relevant parameters are calibrated and estimated based on the existing research and Chinese data， and the transfer strategy of urban construction land quota and its welfare effect is simulated and analyzed. The relevant data of construction land index transfer came from the information platform of savings index transfer linking the increase and decrease of urban and rural construction land in Sichuan Province. It is found that allowing the transfer of urban construction land quota can improve the value of the government objective function， but only when the government takes the residents' welfare as the objective function can the residents' welfare be maximized at the same time； the transfer of urban construction land quota will not only alleviate the shortage of urban land and provide poverty alleviation funds， but also squeeze out government public service expenditure and reduce the construction land in the transferred out areas. The research of this paper provides a basis for the local government to formulate a reasonable transfer strategy of urban construction land quota， coordinate the relationship between regional production and residents' welfare， optimize the spatial layout of China's land， reasonably allocate regional urban and rural land resources， promote regional coordinated development， and realize the high-quality development of new urbanization and the rural revitalization strategy.
