As the main position for grassroots governments to provide public cultural services,grassroots public cultural facilities play an important role in meeting the basic public cultural needs of the masses,protecting the basic cultural rights and interests of the masses,and promoting the construction of the public cultural service system.With the increasing spiritual and cultural needs of the masses in China,the development of grassroots public cultural facilities and services should continue to meet the new needs of the masses for a better cultural life,so it is urgent to further improve the quality of grassroots public cultural services by improving the efficiency of the supply of grassroots public cultural facilities.Taking 30 provinces in China as the research object,this paper uses the SBM model based on undesired output in data envelopment analysis to measure the service supply efficiency of grassroots public cultural facilities in China,and then uses the natural break point method and spatial auto correlation model in Arc GIS to reveal the provincial spatial distribution and correlation characteristics of grassroots public cultural facilities service supply efficiency,and uses geographic detectors to analyze the driving factors of provincial spatial differentiation of grassroots public cultural facilities service supply efficiency from two aspects: internal and external.The study found that:(1)From the perspective of the overall supply efficiency level,the overall level of service supply efficiency of grassroots public cultural facilities in China in 2020 is average,and more than half of the provinces have not achieved the optimal supply efficiency,and there is still much room for improvement and improvement.(2)From the perspective of spatial differentiation,it is embodied in the following two aspects:(1)From the perspective of spatial visualization,the supply efficiency shows significant spatial differences.Among them,the comprehensive technical efficiency of grassroots public cultural facilities service supply presents the characteristics of "falling first from east to west and then rising" U-shape ",rising first and then falling from south to north",and the characteristics of continuous development of high-efficiency horizontal areas and low-efficiency horizontal areas.The trend of pure technical efficiency is similar to the trend of comprehensive technical efficiency;Scale efficiency shows a trend of "decreasing from east to west and flat from north to south".(2)From the perspective of spatial correlation analysis,based on global spatial auto correlation analysis,it is found that the supply efficiency is spatial agglomeration as a whole;Based on local spatial auto correlation,it was found that the low-low agglomeration area contained the largest number of provinces,mainly distributed in the northeast and western regions,followed by the high-high agglomeration area,mainly distributed in the Yangtze River Delta region and the Bohai Rim region,and there were fewer provinces belonging to the high-low agglomeration area and the low-high agglomeration area.(3)From the perspective of driving factors,the economic development level,population density,residents’ education level,urbanization rate,government attention and proportion of professional and technical personnel among internal factors all have a significant positive impact on the efficiency of grassroots public cultural facilities service supply and provincial spatial differentiation.Based on the empirical research conclusions,this paper proposes to promote the flow of grassroots public cultural resources and elements between provinces and improve the level of interconnection of resources and elements.Optimize the structure of fiscal expenditure and promote the balanced development of grassroots public cultural facilities and services;Build a service model based on demand to meet the cultural needs of the masses in different regions;Suggestions on countermeasures to improve the level of urbanization and narrow the gap between urban and rural areas. |
