“…Fiscal decentralization is helpful in giving full play to the information advantages and initiative of local governments, resulting in increased economic efficiency [1][2][3]. However, decentralization may also intensify intergovernmental competition and distort the fiscal choices or the composition of expenditures, for example, by crowding out expenditures lacking direct economic effect, such as public health, education, social welfare, etc., eventually exerting an adverse impact on national development [4][5][6][7][8][9]. As shown by Lockwood (2002) [18], regional or local governments may find it difficult to coordinate in order to internalize interjurisdictional externalities, whereas the cost of centralization is reduced "responsiveness" to the preferences of regions with respect to the provision of public goods.…”
