论经济学研究的范围

On the Scope of Economic Studies

纯经济学的研究范围是生产、分配、交换、消费领域内的经济学基本理论问题，而具体经济学分支学科的研究范围有多大是难以回答的，在所有的研究领域内，只要是同经济有关的，总会是经济学某一分支学科所要研究的问题，随着时间的推移，迟早会出现与此有关的经济学分支学科。新的经济学分支学科的形成通常需要三个条件。经济学研究的尽头就在于经济学所有各个分支学科同其他学科的交叉地带或边缘地带。可持续发展经济学是经济学中一个新的分支学科，洪银兴等同志所著的《可持续发展经济学》一书在这个领域内开了一个很好的头。

The scope of pure economics is basic theoretical issues of economics in the areas of production, distribution, exchange and consumption. However, it is difficult to map out the scope of subdisciplines of economics. In all research areas, whatever is related to economy will become issues of a subdiscipline of economics, and with the change of time, a relevant subdiscipline of economics will emerge sooner or later. Three conditions are required for the formation of a new subdiscipline of economics. The other end of economic studies will be the overlapping or peripheral area where all the subdisciplines of economics meet with other disciplines. Sustainable growth economics is a new subdiscipline of economics, and Hong Yinxing's Sustainable Crowth Economics marks a good start in that direction.
