目的 分析广西各地级市常住人口、国土面积、人口密度、国内生产总值、人均国内生产总值与乙类大型医用设备配置量的关联关系,以期为卫生计生部门优化乙类大型医用设备配置提供参考依据.方法 利用灰色关联分析模型,得到乙类大型医用设备配置量与常住人口、国土面积、人口密度、国内生产总值、人均国内生产总值关联性的灰关联序.结果 各地级市常住人口、国土面积、人口密度、国内生产总值、人均国内生产总值与乙类大型医用设备配置量的灰色关联度分别为0.8262、0.6839、0.6949、0.9471、0.6782.结论 各地级市国内生产总值是影响乙类大型医用设备配置量的主要因素,常住人口、国土面积、人口密度、人均国内生产总值均对大型医用设备配置量有一定影响.%Objective Through analyzing the correlation among the number of second-class large medical equipment and common indexes including population, land area, population density, gross domestic product and per capita gross domestic product of each city in Guangxi, this paper aimed to provide references for the health department to rationalize the allocation of second-class large medical equipment. Methods We used the gray correlation analysis model to get gray relational sequence of relevance between second-class large medical equipment and these common indexes. Results The degree of gray correlation between second-class large medical equipment and population, land area, population density, gross domestic product, per capita gross domestic product was 0.8262, 0.6839, 0.6949, 0.9471 and 0.6782, respectively. Conclusion Gross domestic product was the main factor that influenced the number of second-class large medical equipment of each city. Population, land area, population density, and per capita gross domestic product also influenced the number of second-class large medical equipment to some extent.
