如果对国内各地区和世界奋发展中国家的发展状况略作比较,就不难发现发展的不平衡性,有的地区和国家发展较快,有的地区和国家发展较慢。再进一步分析还可发现,在发展不平衡性中还存在着“跳跃”现象,即有些原来发展水平较低的地区和国家,在不太长久的时间里赶上并超过了原来发展水平较高的地区和国家,而一些发展水平较高的地区和国家却被原来的后进者赶过去了。 If we compare the development status of developing countries in various regions in the world with the world, it is not hard to find the development imbalance. Some regions and countries develop rapidly, and some regions and countries develop slowly. Further analysis can also find that there is still a “jump” in the development imbalance, that is, some regions and countries that were originally underdeveloped catch up with and surpass the previous high development level Regions and countries, while some areas and countries with higher levels of development were overtaken by the original backward ones.
