| As China’s urbanization enters the mid to late stage of development,there is a new trend in urban-rural population mobility.Under the influence of regional economic development and industrial transformation and upgrading,the flow of urban and rural population has gradually shifted from traditional one-way flow from rural to urban areas to two-way flow between rural and urban areas,and the county has gradually become a new space for local urbanization.At the same time,with the continuous improvement of rural living standards,the demand for highquality public service facilities among rural residents is increasing.However,the current static and homogeneous configuration of public service facilities is difficult to adapt to the spatial distribution of public service demand under the new trend of population mobility.Therefore,how to adapt the configuration of public service facilities to the spatial distribution of population will be a key issue that urgently needs to be solved in the future configuration of public service facilities.Firstly,this study is based on the concept of balancing fairness and efficiency in the allocation of public service facilities,and constructs a differentiated framework for evaluating the rationality of public service facility allocation from both static and dynamic perspectives.Then,based on the above analytical framework,evaluate the rationality of the current configuration of public service facilities in six major categories and fifteen sub categories within the emerging county.Finally,optimization strategies are proposed to address the problems in the allocation of rural public service facilities in Xinxing County.(1)From a static perspective,the rationality evaluation of the supply and demand relationship of public service facilities is conducted using the "thousand person indicator" evaluation method based on age groups.From a dynamic perspective,distinguish between short-term travel characteristics and long-term mobility characteristics,and measure the travel time cost,coverage,and achievable quantity of public service facilities under different shortterm travel modes through network analysis methods;Adopt scenario analysis to set up multiple future population mobility scenarios and evaluate the rationality of the supply and demand relationship of public service facilities under long-term population mobility.The evaluation method of "thousand person indicator" by age group and scenario analysis method can fully reflect the adaptability relationship between county public service facilities and population,and the analysis framework has important reference value for improving the configuration technology of county public service facilities.By paying attention to the age structure of the population,the previous static evaluation method of the "thousand person indicator" has been improved,which effectively compensates for the shortcomings of evaluating the rationality of county public infrastructure configuration from a dynamic perspective.(2)The adaptation relationship between public service facilities in Xinxing County and vulnerable populations is poor.The proportion of elderly population in Xinxing County is relatively high,and the degree of aging is relatively deep.However,the corresponding configuration of elderly care facilities is relatively small,and the current supply of elderly care homes in each town does not match the number of elderly population.Over time,the elderly population will be the main population in the future county,and it is particularly important to tilt the relevant public service facilities towards it.In addition,the adaptation relationship between kindergartens in Xinxing County and the population of young children is mainly dominated by administrative villages with missed or low matching.There is uncertainty in the future changes in the population of young children,and the allocation of kindergartens needs to comprehensively consider the trend of future changes in the population of young children.(2)The reachability of administrative villages to various public service facilities under different travel modes in Xinxing County presents the spatial characteristics of "double centers" and "circle decreasing".Taking the central urban area of Xinxing County and the center of Tiantang Town as the core,the travel time cost increases with the increase of the distance between the administrative village and the core,while the number of accessible areas decreases with the increase of distance.The travel time cost of administrative villages in remote mountainous areas is relatively high,and the number of accessible villages is relatively small.In addition,there are differences in reachability characteristics between village/group level public service facilities and township level public service facilities,mainly reflected in the number of accessible administrative villages.The increase in randomness and travel time costs has led to an increase in the number of public service facilities at the village/group level in each administrative village.The difference in the number of public service facilities at the township level among administrative villages is opposite,and the degree of randomness increases and the cost of travel time gradually decreases.(3)The supply and demand relationship of public service facilities between the central urban area of Xinxing County and grassroots administrative villages is tense.In the evaluation of the rationality of public service facility allocation under the multi scenario population flow in Xinxing County,it was found that the supply and demand relationship of public service facilities in administrative villages in the central urban area is mostly of a low allocation type.Administrative villages near the center of each town are mostly of a high allocation type,while grassroots administrative villages are mainly of low allocation and missing allocation.The supply and demand of public service facilities in Xinxing County show that the supply in the central urban area and grassroots administrative villages is less than the demand in space,and the supply of public service facilities in each town center is greater than the demand.(4)The optimization of public service facility allocation in Xinxing County should follow the principles of balancing urban and rural areas,people-oriented,dynamic adaptation,and resource conservation.It is necessary to delineate the scope of the living circle based on the objective reality of rural residents’ travel,grasp the supply and demand relationship of public service facilities,improve the configuration system of public service facilities,and timely adjust and update public service facilities based on population mobility. |
