Impact and Mechanism of Fiscal Decentralization on New Urbanization:Testing of Transmission Effect and Threshold Model Based on Public Finance Expenditure
Based on panel data from 31 provinces in China from 2010 to 2021,an econometric model was con-structed to empirically test the impact and mechanism of fiscal decentralization on new urbanization.The re-sults show that:fiscal decentralization has a significant promoting effect on new urbanization,and the higher the local government obtains fiscal autonomy,the greater the incentive effect on the improvement of new ur-banization;regional heterogeneity testing finds that fiscal decentralization has a more significant promoting ef-fect on new urbanization in the eastern and western regions,while the promoting effect is not significant in the central region;the threshold model test finds that there is a dual threshold effect of public fiscal expenditure on new urbanization,only when fiscal decentralization reaches a certain degree can the promotion effect of fis-cal decentralization on new urbanization be better exerted.Research suggests that the fiscal decentralization system should be further reformed,inappropriate allocation of fiscal resources should be corrected,the effi-ciency of local public fiscal expenditure should be improved,and the process of urbanization centered on people should be effectively promoted.
