一、50年代和60年代初对发达国家模式的盲目仿效。这种仿效的内容包括直接输入发达国家的先进农业技术方法和农村社会体制等各个方面。但是所有的仿效几乎都以失败告终。其原因主要是发展中国家的农村发展存在非常明显的结构性障碍,也即社会政治经济背景乃至文化背景与发达国家大相径庭。 First, the blind imitation of developed countries in the 1950s and early 1960s. The follow-up includes direct input to advanced agricultural technology methods in developed countries and various aspects of rural social system. But almost all imitation ended in failure. The main reason is that there are obvious structural obstacles in rural development in developing countries, that is, socio-political, economic and cultural backgrounds are quite different from those in developed countries.
