布坎南是来自美国的经济学家,理学学士,后来获得文学硕士和哲学博士学位,但是他真正的杰出贡献却是在经济学的领域中,并将这些经济理论运用于政治制度和法律改革。他将经济的概念引入政治学的领域中,创造性地理解了“经济基础决定上层建筑”的观点,认为政治和法律就是为上层建筑服务的,所以政治和法律不可避免的带有阶级性,也难以逃脱对上层建筑的服务性。他本人因为其特定的理论获得了诺贝尔奖,其理论和我们的国家政策和制度有一定偏差,但是却能够起到参照作用。 Buchanan, an economist from the United States, received his bachelor of science and later a master’s degree in literature and a doctorate of philosophy, but his real outstanding contribution was in the realm of economics and applied these economic theories to the political system and law reform . He introduced the concept of economy into the field of politics and creatively understood the view that “economic foundation determines superstructure ” that politics and law serve the superstructure, so politics and law inevitably have a class nature, It is difficult to escape the service on the superstructure. He himself won the Nobel Prize for his particular theory, and his theory has a certain deviation from our national policies and systems, but it can serve as a reference.
