Abstract:Objective：To investigate the equipment configuration of county-level CDCs in Jiangsu Province，analyze the deficiencies，and put forward suggestions for optimizing the equipment configuration of county-level CDCs，improving the on-site detection capacity of common diseases，frequently occurring diseases and general public health emergencies. Methods：The questionnaire was designed to collect the equipment configuration and demand status of county-level CDCs in Jiangsu Province，and the status and fairness were analyzed through descriptive analysis and Gini coefficient. Result：In Jiangsu Province，the average compliance rate of the three types of equipment in terms of type and quantity is 64.1% and 80.33%，55.32% and 47.66%，25% and 31.03% respectively，showing the trend of northern Jiangsu < central Jiangsu < southern Jiangsu；the Gini coefficientA=0.35，Gini coefficientB=0.36，Gini coefficientC=0.48. Conclusion：All of the equipment of county-level CDCs in Jiangsu Province are not up to the national standard；the difference of compliance rate among the north，the middle and the south of Jiangsu is large；the configuration of class A and class B equipment is more fair than that of class C equipment. It is suggested to strengthen the investment of special funds for equipment and the assessment of equipment；clarify the laboratory positioning of county-level CDCs，revise the equipment configuration standards；coordinate the management of laboratory equipment to achieve information management.
