人力资本理论认为,教育投入的增加.有利于改善人力资本水平,从而提高居民收入,缩小地区差距。本文通过建立人均GDP与受过高中教育的人口的比重间的模型,实证表明,增加各地区的高中教育人口所占比重,尤其是欠发达地区,提高人口的素质,这对于提高人均收入,改善居民的收入,缩小地区收入具有重要的现实意义。 Human capital theory holds that the increase of investment in education is conducive to improving the level of human capital so as to raise the income of residents and narrow the gap between regions. By establishing a model of per capita GDP and proportion of population with high school education, this paper empirically shows that increasing the proportion of high school education population in all regions, especially in less developed areas, and improving the quality of population is not only conducive to raising per capita income and improving residents’ Income, narrowing the area of ​​income has important practical significance.
