基于手机信令数据的镇级医疗设施评估——以中山市西北组团为例

Medical Facilities Evaluation Based on the Measurements of Mobile Signaling Data:A Case Study of Northwest District in Zhongshan

目前,现有的医疗设施评估研究多从可达性或均等性单一视角开展,所用数据的精确度、时效性均不足,评估结果容易产生偏差甚至误导。对此,本文选取时效性较高的POI和手机信令数据,以分级分类的医疗设施可达范围的综合覆盖次数表征可达性强度,以可达性强度和居民空间分布的耦合情况表征均等性水平,从可达性和均等性两个角度对广东省中山市西北组团的镇级医疗设施展开综合评估。结果显示中山市西北组团的医疗设施可达性相对较好,服务范围覆盖较大;总体均等性较好,但局部仍存在医疗设施服务强度和居民分布数量不相匹配的现象。最后文章基于评估结果将研究单元划分了四类,并针对每一类提出对应的提升策略。

Currently,the majority of medical facility evaluations are usually conducted from a single start point,such as accessibility or equality,and the accuracy of data adopted in these evaluations is relatively weak,which may mislead the consequences of evaluation.Thus,this paper harnesses a newly emerging timeliness data,POI and mobile signaling data,to comprehensively evaluate medical facilities in northwest district of Zhongshan from both accessibility and equality aspects,where accessibility is described as the coverage times of medical facilities and equality is depicted as the distribution difference between accessibility and residential.The result shows that the global accessibility and equality of northwest district are relatively optimistic with large service coverage,but there is still some unbalance of equality at local level where medical facilities service and residents distribution are mismatched.Finally,based on the evaluation results,the research units are divided into four categories and each category is given corresponding promotion strategies.
