补充资料：卫生服务生产与边际效益递减规律
卫生服务生产与边际效益递减规律
卫生服务生产与边际效益递减规律卫生服务是一种以服务形式存在的产品，具有劳动者(医务人员)、劳动对象(患者)和劳动资料(医疗器械、药品等)三个基本要素，具有生产、交换、分配和消费四个环节。但卫生服务生产又有自身的特点。由于卫生服务生产是一种劳务产品，不像其他物质产品那样可以储存和运送，而是“随产随销”，卫生服务生产在数量上的多少可造成卫生服务消费的短缺和过剩。因此，要求卫生服务生产的结构和布局应当相对合理卫生服务生产价格取决于医疗卫生消费者主观心理所感觉到的卫生服务生产最后一个单位的效用，即在确定某项卫生服务生产的价格时，必须依据效益递减规律。边际效益对价值的决定依赖于卫生服务的供求关系，供给越多，需求不变，边际效益越低，卫生服务价格越低;反之，需求越大，供给不变，边际效益越高，卫生服务生产价格越高。
