除学校投入的教育资源差异外,不同地区的价格差异也会引起义务教育成本的差异。美国学者从20世纪70年代最早开始了对义务教育地区成本差异的调整研究,而中国在这一领域的研究几乎仍旧是一片空白,因此,有必要梳理近半个世纪以来关于教育成本调整的主要英文文献,对教育成本指数的构造步骤及各种构造方法进行阐述和评论。 In addition to the differences in educational resources invested in schools, price differences in different regions can also cause differences in compulsory education costs. Since the early 1970s, American scholars started to study the adjustment of the differences in the cost of compulsory education. However, the study of China in this area is still almost empty. Therefore, it is necessary to sort out the main changes in education costs in the past half century English literature, the construction of education cost index steps and various construction methods to elaborate and comment.
