Abstract: The quality of basic public service is an important index of the economic development level and social civilization of a region or city. By establishing the evaluation system of basic public service, this article evaluated the level of basic public service in Hunan Province, then analyzed the spatial pattern of basic public service quality by using the spatial autocorrelation method, and finally studied the spatial spillover effects and the influence factors of basic public service by using Spatial Durbin Model. The results showed that, （1) The level of basic public service quality in cities of Hunan Province showed a different degree of upward trend from 2008 to 2017, but the overall level was not high. The spatial pattern showed a semiannular belt structure that attenuated from east to west. (2) The basic public service had significant global and local autocorrelation in the interurban city. The various types of basic public service showed the spatial evolution mode of agglomerationdispersionagglomeration. The local autocorrelation results showed that the spatial club convergence characteristics of H-H and L-L agglomeration was obvious. The distribution and amount of various agglomeration types remained stable. (3) The spatial Durbin Model test showed that there existed spatial spillover effects of basic public service among cities in Hunan Province. The level of regional basic public service was not only influenced by the region itself factors, also affected by the basic public service level of adjacent areas. The regression results showed that the urbanization level, level of openingup, local financial expenditure and regional economic vitality had a positive influence on the basic public service.
