从发展中国家31个中等城市的例子中,我发现了历史上曾对它们的发展产生过影响的因素,研究了它们的发展动态。我认为未来的地区性的和全国性的最有效的发展方法是依靠它们本地的社会经济能力。发展素因大多数发展中国家的城市人口只是最近才达到10万或稍多一些。我们现在在发展中国家听到的高度集中的城市发展类型是在本世纪初出现的。 From the examples of 31 medium-sized cities in developing countries, I found the factors that have historically affected their development and studied their developments. I think the most effective development method for the future, both regional and national, will depend on their local socio-economic capabilities. Growth factors The urban population in most developing countries only reached 100,000 or slightly more recently. The highly concentrated type of urban development that we are hearing in developing countries now appears at the beginning of this century.
