实现健康公平是实现共同富裕不可或缺的一环，是共同富裕在卫生健康领域的贯彻和体现。以健康公平推进共同富裕，是新时代卫生健康工作的根本遵循，也是实现共同富裕的题中应有之义。健康公平推进共同富裕以中国特色社会主义政治经济学为理论基础，其基本逻辑是健康公平和共同富裕相互融合、相互促进、高度统一，主要表现为全民性、全面性、均等性和循序性；以健康公平推进共同富裕的实现机制包括提供高质量更广范围的健康供给、增加健康供给可及性、循序渐进分阶段发展。基于此，应积极推进健康领域供给侧结构性改革，在公共卫生服务、医疗卫生资源等方面做大健康“蛋糕”，同时缩小城乡、地区、人群间的健康不平等，分好健康“蛋糕”，真正发挥健康公平的“共富”效应。
