In recent years, the problem of equalization supply of local public services has been increasingly concerned by all sectors of society. The report of the Party's 20th National Congress and the decision of the Third Plenary Session of the 20th Central Committee also stressed the need to "enhance the equalization and accessibility of basic public services". How to better straighten out the fiscal management system among multi-level governments, and give full play to the two positivity of "superior government" and "local government" in the supply of public services is particularly important for ensuring the equalization and accessibility of public services. From the perspective of the fiscal management system, the relevant theoretical literature on the equalization supply of local public services in China was sorted out. It find that, firstly, significant regional and urban-rural differences exist in the supply of local public services in China, with the imbalance in the supply of education and healthcare being particularly prominent. Secondly, factors including the fiscal decentralization system, local governments' promotion incentives and the fiscal expenditure structure are major causes for the imbalance in local public service supply. Thirdly, public policies like increasing public expenditures, enhancing transfer payments, promoting household registration reform and encouraging government service procurement are conducive to improving the supply of local public services. Finally, reform measures of the fiscal management system, such as the division of affairs rights and expenditure responsibilities and the optimized design of inter-governmental fiscal relations, have a remarkable impact on the balance and accessibility of local public service supply.
