中文摘要：

本文依据一个国家在不同经济发展阶段合理的人口年龄结构就我国人口年龄结构对社会经济发展的影响进行了分析。当前我国人口年龄结构中0-14岁少年儿童人口比例仅为16.41%,60及60岁以上老年人口比例高达14.90%,且少年儿童比例和老年人口比例均呈现出继续下降和上升的态势。这一人口年龄结构及发展态势将使我国的社会经济在发展中呈现出后续劳动力资源不足,经济活动人口短缺、经济活动人口老化等一系列问题。为了有效地降低我国人口年龄结构对社会经济发展的负面影响,本文从调整我国人口政策、延迟退休年龄、加强人力资本投资及建立适合我国国情的养老保障体制等方面提出了相应政策建议,以利于我国工业化进程的顺利完成和整个社会经济的可持续发展。
