环节

农业

文明

生产力极为低下,劳动力不足且无节制生育导致极高的出生率;而频繁的战争、食物匮乏和极差的医疗卫生条件死亡率奇高。

原因:社会生产力的发展

开始:从死亡率的下降开始;

实现:出生率的下降最终促使人口再生产类型转变的实现

工业

文明

随着工业化的发展,生活质量不断提高,死亡率下降;同时劳动生产率也极大提高,加上节育措施逐渐普及,出生率开始下降。代表性国家如巴西等。

增加社会劳动力,增加社会财富,促进社会发展,同时促进城市化进程;

过多的人口造成社会就业压力空前,导致环境污染,生态破坏,能源紧缺,社会难以安定等一系列问题

后工业

文明

现代科学和技术飞速发展,推动了社会进步和生活观念的变革,出生率很低;死亡率因人口老年化而有所上升。代表性国家如德国等。

有效缓解人口迅猛增长的趋势,使区域人口从严重的不平衡状态回复到新的基本平衡状态。

使得社会劳动力缺乏,不利于产业发展,不利于国家的经济发展;并出现人口老龄化严重,增加社会福利负担,更不利于国家的财政建设。
