1, at the national level: policies are mainly reflected in the control of macro-policy direction. For example, in solving the demand for renovation funds, it is required to increase financial subsidies and bank credit support, provide national policy loan funds (PSL funds) through the China Development Bank and the Agricultural Development Bank to support the renovation of shanty towns, and at the same time clearly give preferential treatment to local governments with weak financial resources in the central and western regions; In support of local government work, simplify the land supply process of shed reform projects, accelerate the orderly cycle between the transformation and development of shed reform projects, and increase tax and fee reduction policies to support the implementation of shantytown projects; In terms of benefiting the residents of shanty towns, we encourage the implementation of supporting infrastructure projects, improve the surrounding facilities of shanty towns, carry out monetary resettlement, shorten the resettlement period, meet the diversified resettlement needs of the transformed people, and compensate the residents who have changed sheds or purchase resettlement houses or reduce the corresponding taxes and fees. 2. Municipal level: For supporting policies, we should pay more attention to how to solve the housing problem of shantytown residents and how to speed up the implementation of shantytown projects. For example, in terms of compensation and resettlement, the monetary resettlement policy has been established, and the residents of shed reform can sign compensation agreements in the form of "monetary compensation+property right exchange" and "monetary compensation+independent house purchase" according to the principle of "equivalent exchange", and the purchase price of resettlement houses is obviously lower than that of commercial houses sold in the market. At the same time, compensation and assistance policies such as one-time special reward for monetary resettlement, minimum living guarantee area per capita, compulsory education for children, minimum living guarantee payment and re-employment have been established. In supporting the work of district and county governments, it is mainly to increase financial support and strengthen work guidance, such as arranging district and county subsidy funds year by year through the municipal finance, dividing the income from shed reform projects into municipal parts and returning them to the district and county governments to support the transformation work, guiding the implementation of the national shed reform tax reduction and exemption policy, optimizing land supply and project control procedures, and helping the district and county governments to implement the national policy loan funds.
