浅谈中国人口老龄化的基本形势及面临的主要问题　　论文摘要：中国是在经济实力较弱、制度准备迟滞的情况下进入老龄社会的，现行养老保障体系、医疗保障体制、老年照料服务体系和传统管理体制都没有跟上人口老龄化快速发展的要求，是人口老龄化形势最为严峻的发展中国家。　　论文关键词：人口老龄化；老龄社会；养老保障；医疗保障；老年照料服务　　一、中国人口老龄化的基本形势　　人口老龄化是经济和社会发展到一定阶段的产物，涉及到国家经济、政治、文化、社会建设等诸多领域，是关系到国计民生和国家可持续发展的重大社会问题和战略问题。当前，我国正处于全面建设小康社会、加快推进社会主义现代化的新的发展阶段．正处于体制深刻转换、结构深刻调整、社会深刻变革的重要时期，也是应对人口老龄化十分关键的时期。当前，我国人口老龄化形势已经十分严峻．面临着人口老龄化和人口总量过多的双重压力。　　按照国际标准，我国已处于老龄社会，并进入快速发展时期。目前我国60岁以上老年人口已达1．44亿，占总人口的1l％，并将以年均3％速度增加。我国已成为世界上唯一老年人口超过1亿的国家，也是发展中国家大国崛起过程中人口老龄化最严峻的国家。据预测，2010年我国老年人口将达到1．74亿，约占总人口的12．8％；2020年将达到2．48亿，约占总人口的17．2％。从2005年到2020年，我国老年人口要净增1亿。之后进入高速发展阶段，到2050年前后提升到30％以上，进入重度老龄化。届时我国老龄人口总量比美国全部人口还多。从本世纪前半叶开始，我国将始终是世界上老年人口规模最大国家。我国老龄化水平从10％提高到30％，仅用不到50年时间，而英国、法国和美国等西方工业化国家要用100年左右的时间。对于一个发展中的人口大国而言，这一速度的确是惊人的。　　随着人口老龄化的快速发展，我国家庭结构、老年群体状况及城乡老年人口分布将呈现许多变化。一是纯老年人家庭迅速增加。“三代同堂”式的传统家庭越来越少，“四二一”结构家庭(一对夫妇同时瞻养四个老人和一个小孩)逐渐增多。有关调查显示，目前我国纯老年人家庭占老年人家庭比例城市约为40．3％，农村约为37．8％，并在继续增加。二是高龄老年人口急剧增长。我国人均预期寿命已达71．4岁，80岁以上高龄老人高达1520万，预计到2020年将翻一翻，2052年将超过1亿，占世界高龄老人总量的1／4。高龄老人是老年人口中增长最快的群体，本世纪前半叶，我国高龄老年人平均增长率超过4％，是老年人口平均增长率的1．7倍。高龄老人的这种增长速度在世界人口老龄化历史上是十分罕见的。三是城乡人口老龄化程度倒置。发达国家城市人口老龄化水平一般高于农村，我国的情况则相反。2000年我国农村老龄化水平为10．9％，比城镇高1．24个百分点，2020年、2030年将分别高于城镇5个和7个百分点。老龄化对农村的冲击比城镇更为严重。这是中国人口老龄化不同于发达国家的重要特征。四是老龄化超前于现代化。我国是在尚未实现现代化，经济尚不发达的情况下提前进入老龄社会的，属于未富先老。而发达国家是在基本实现现代化，经济较为发达的情况下自然进入老龄社会的，属于先富后老。　　中国进入老龄化社会时人均GDP刚刚超过1000美元，属于中等偏低收入国家行列，而发达国家进入老龄社会时人均GDP一般都在5000—100013美元以上。人口老龄化的迅速发展对经济社会发展的影响十分广泛而深远。人口老龄化使劳动力年龄结构、人口瞻养比结构、代际利益关系发生重大变化，对养老、医疗服务体系的完善，对政府社会管理和公共服务职能的加强，对老年文化、教育、卫生、体育事业的发展，都提出了新的更高的要求。　　二、中国人口老龄化面临的主要问题　　中国是在经济尚不发达的情况下进入老龄社会的，应对人口老龄化的经济实力较弱，制度准备也较为迟滞，面临的形势相当严峻。　　一是现行养老保障体系还不适应人口老龄化快速发展的要求。充足稳定的养老金供给是养老保障制度的核心和可持续发展的关键。我国的快速老龄化将导致抚养结构的根本性转变，造成在本已较迟建立养老保险制度的情况下，养老金缴费者急剧减少和领取者大量增多，养老金供需矛盾日益尖锐。一方面，我国现行养老保险制度的资金支付压力逐年加大。1980年我国在职职工与离退休人员之比为l2．8：1，2004年锐减到3：1，养老负担急剧加重。另一方面，由于长期形成的城乡二元经济结构，使我国现行养老保险制度覆盖面窄，只在城镇建立起养老保险制度，绝大多数农村老龄人口还没有纳入社会养老保险制度。因此，完善养老保险制度的任务十分艰巨。　　二是医疗保障体制不适应老年群体迅猛增加的要求。老年人是医疗卫生资源消费的主体，据统计，60岁以上老人余寿中约有2／3时间为带病期。而目前我国医疗资源总体不足、分布不均衡，医疗保障制度覆盖面小，政府投入相对不足，个人负担费用上涨过快。老年人口总量的迅速增长，对医疗资源的消费和占用越来越大，而支付能力有限，这将给我国医疗保障体系带来巨大压力和严峻考验。　　三是老年照料服务体系不适应老年人服务需求增长的要求。不断增多的高龄、病残、独居老人。要求提供社会照料服务需求的日益增多。目前，我国约有3250万老人需要不同形式的长期照料护理服务。但社会养老床位数占老年人的总数只有0．84％，而发达国家约为7％。这表明，我国老年照料服务体系建设严重滞后，服务能力需要大力加强。　　四是传统管理体制不适应社会化管理和服务的要求。随着各项改革的深化和政府职能的转换，企业退休人员由“单位人”转为“社会人”，越来越多的退休人员都将进入社区，对其实行社会化管理和服务已成必然。这就要求社区承担起健全老年工作机制、培育和发展老年群众组织、维护老年人合法权益、提供老年活动项目、活跃老年人精神文化生活、引导老年人参与经济发展和社会事务等任务，迫切要求加强社区建设，发展社区服务。但我国的社区建设尚处于起步和探索阶段，社区服务体系还很不健全，服务能力和服务水平都亟待快速提升。

the ups and downs of population growth As is seen from the two graphs， it is clear that with the rapid growth of US population from 1800 to 1990， the number of its wildlife species no longer existing soared during the same Naturally， we can draw the conclusion that the sharp decline of wildlife species resulted from the population Two reasons may account for this To begin with， as the population grows， people consume much more natural resources， which often leads to excessive Second， with the increase of human activities， modern people take up more and more Which has a great impact on other Finally， the problem of pollution becomes more and more serious with the development of modern More and more animals have to adapt themselves to the decaying environment or move to a totally different place， but not all of them are fortunate enough to survive the Solving this problem calls for， above all， the government’s efforts to control population growth， to decrease industrial pollution and to enhance the laws to forbid wildlife Moreover， common citizens should be aware of this ecological crisis and take on the responsibility of wildlife In a word， only when the government and the common people make joint e f forts can we hope to find a satisfactory solution to this
