根据研究对象的不同,研究方法的不同,甚至研究结果的不同,经济学可划分为不同的领域和分支,并由此形成了不同的学派和流派。没有放之四海而皆准的定律,不过是研究的某项题材分量轻重有别,研究的方法成熟路径不一,研究得出的见解深浅各异。真理是相对的,无数个相对真理的总和,才构成对经济完整的认识。经济在时间和空间的二维中运行,经济学是此二维结合的产物。不同的经济学原理,适用于不同的区域和不同的历史阶段。比方说,北欧的福利虽好,但难以普 According to different subjects, different research methods, and even different research results, economics can be divided into different fields and branches, and thus different schools and schools have formed. There is no universality of the law, but the weight of a subject matter is different, the methods of research are different and the findings of the research vary in depth. Truth is relative.
