目前世界各国平均预期寿命的地区差异显著，不仅平均预期寿命高低悬殊，而且两性差正负不同，并呈“富国寿长、穷国命短”两极分布。通过因子分析发现，医疗文卫因素、政府投入因素和伤害归因因素是造成平均预期寿命地区差异显著的主要原因。通过聚类分析将世界各国分成了三大类地区，验证了上述因子对三类地区影响是显著的。最后指出，大力发展经济、加快城市化进程、改善医疗卫生条件、降低婴儿死亡率和传染性疾病死亡率是缩小世界各国平均预期寿命地区差异的有效路径。

At present, the regional differences of life expectancy are notable in the world： Life expectancy levels are significantly different; Gender gap is positively or negatively different; there exists a bipolar distribution with a longer life expectancy in rich countries, and shorter in poor ones. Through factor analysis, such factors are found as the main causes of the regional differences： public health and culture, government investment, and attribution of injury. By cluster analysis, the world is divided into three regions, and the conclusion is verified that the influence of the above factors on the three regions are remarkable. Effective ways are finally proposed in the paper to reduce the differences, developing economy, speeding up the urbanization, improving medical conditions, and bringing down infant mortality and infectious disease mortality.
