摘要目的:分析我国职业病防治技术支撑体系发展现状和存在的问题，提出发展措施与建议。方法:于2021年1月，采用整群抽样方法，对全国职业病防治技术支撑相关机构进行问卷调查。主要调查职业病防治院（所）、市县级疾控中心、职业健康检查、职业病诊断和职业健康中介服务等机构发展情况。用数和构成比（%）进行数据描述，对数据进行描述性分析。结果:截至2020年12月，全国共有职业病防治院（所）140家，与2019年比较，增加65家。承担职业病防治工作的市、县级疾控中心分别为323、2 704家，分别占疾控中心总数的97.00%（323/333）、95.01%（2 704/2 846）。全国共有职业健康检查机构4 520家，职业病诊断机构587家，职业卫生技术服务机构1 093家，放射卫生技术服务机构623家。结论:职业病防治技术支撑力量和能力有待提升，职业病防治院（所）的力量还较薄弱；市、县级疾控中心需进一步完善条件、提升能力；职业健康检查、职业病诊断治疗康复机构数量相对不足。
