长期以来，我国医疗服务价格体系存在着许多问题，医疗服务价格既不能反映医护工作者的技术劳务价值和医院医疗成本，又不能反映群众需求，影响医护人员积极性，导致“以药养医”，造成群众看病难，看病贵。2016年我国《推进医疗服务价格改革的意见》提出，到2020年，要逐步建立以成本和收入结构变化为基础的价格动态调整机制。实行分级定价，根据医疗机构等级、医师级别和市场需求等因素，对医疗服务制定不同价格，拉开价格差距，引导患者合理就医。同时《意见》强调，各地要按照“总量控制、结构调整、有升有降、逐步到位”的要求，统筹考虑各方面承受能力，尤其是中低收入老百姓的承受能力，合理制定和调整医疗服务价格，并与医保支付、医疗控费政策同步实施，在保证医疗服务质量的前提下，确保群众费用负担总体不增加。

结合材料和所学“生活与消费”的有关知识，分析我国推进医疗服务价格改革措施的依据。

    Black Friday

    Thanksgiving is always on a Thursday.The day after it has been known as Black Friday. It is the start of the holiday shopping season,and it has been the busiest shoppingday of the year in the US since 2005.

    Most stores offer big sales on Black Friday.They open their doors quite early in the morning.They try to attract shoppers with big discounts(打折).Some items(商品) like TVs and clothes are much cheaper than usual.Stores may even lose money on these items.They hope that shoppers will buy gifts for other people while they are in the store.However,there are problems.The biggest one is that there are not enough low—priced items. Each store may only have a few so that not everyone can get one.

    The situation makes people worried.Some Black Friday events have been crazy. There have been fights over toys among shoppers. Some workers have even been hurt by large crowds. But most Black Friday events are safe and fun..So where does the name “Black Friday”come from? It was firstused in Philadelphia in the 1950s.

    Now people all over the country take part in Black Friday events.It is even spreading to other parts of the world.Stores have held Black Friday events in the UK，Australia ，and Brazil since 2012. In Mexico，stores offer a weekend of discounts every year. They call it “El Buen Fin”,which means“the good weekend ”in Spanish. I guess people everywhere like to buy things on sale.
