A: (1) Dependence theory first came into being in the field of world economic research in 1960s. Since 1970s, some western comparative educators, such as Canoy, Altbach and Kelly in the United States, have applied this theory to the study of comparative education. (2) Dependency theory divides the world into "center" composed of western developed countries and "periphery" mainly composed of third world countries, and tries to explain the unequal relationship between developed countries and underdeveloped countries with this "center-periphery" overall relationship model. (3) Countries in the central position always try to gain benefits from the control of marginal countries, which have to rely on the central country because of various constraints. (4) The western-style school education system transplanted from developed countries in developing countries actually damages the inheritance of their traditional culture and the cultivation of national consciousness, but on the other hand, it cultivates elites who are pro-central and alienated from their own culture. (5) When transplanting the educational systems, theories, contents and methods of developed countries, developing countries must base themselves on the local society and devote themselves to the localization of these western systems, theories, contents and methods.
