Measurement and Analysis of the Stability of Local Fiscal Revenue

The stability of fiscal revenue, so called the fluctuation of fiscal revenue, refers to the fluctuation degree of local government's actual fiscal revenue deviating from the expected fiscal revenue. As the main way of funds for local governments to perform public service functions, fiscal revenue is an important starting point for local governments to regulate and participate in economic activities. The drastic fluctuation of fiscal revenue will interfere with the government's economic functions, reduce the quantity and quality of public services, and produce inefficient government activities. The economic and social activities carried out by governments at all levels in practice are numerous and complicated, which can be classified according to different purposes and perspectives. However, no matter which classification method is adopted, stable financial revenue is the core guarantee of government economic activities, which is in the position of "leading the development and affecting the whole body". Based on the combination variance method of white (1983), this paper constructs the stability index of local fiscal revenue, and measures the stability of fiscal revenue of all provinces in China, and interprets and analyzes the measurement results through the theoretical method of economics. It is found that there are significant regional differences in the fluctuation of local fiscal revenue in China. By comparing the changes of fiscal revenue fluctuation index in 2000, 2009 and 2018, the fluctuation index of fiscal revenue shows obvious regional differences. The fluctuation degree of the economically developed eastern coastal area is lower than that of the underdeveloped central and Western Region, and the southern region with lower economic activity is significantly lower than that of the north. On the other hand, the external shocks such as "replacing business tax with value-added tax" and financial crisis also have a positive impact on local tax fluctuations. Through the analysis of the experimental results, it is found that good economic foundation, capital accumulation, industrial structure and geographical location have a great impact on financial stability. Therefore, the government should pay attention to the gap between the stability of fiscal revenue in different regions, actively improve the economic foundation of the poor stability of the central and western regions, formulate differentiated economic and financial policies, vigorously develop the secondary and tertiary industries, and improve the stability of fiscal revenue to cope with regional economic risks and improve the administrative efficiency of the government.
