从微观经济学的体系设置看“经济人”的资本本性

Consumer and producer are two behavior subjects of microeconomics. Through the analysis of the consistency of the research methods of consumer and producer theories, the paper reveals the theoretical symmetry and behavioral similarities of the two behaviors, and discusses the ethics and value orientation behind the theories of behavior choice of market subjects from the angle of microeconomic system. From the angle of the system, as the basis of western economics, ”economic man” is a humanized expression of corporate behavior. Its prototype is capitalist, and it is a personified capital relationship. Objectively, the accuracy of economic forecast by using western economics, which is based on ”economic man” hypothesis, depends on the position of capital in economic and the social life. The stronger of its dominant position, the more rational of the capital, and the more accurate of the forecasted results. The author gives suggestions to learners, teachers and researchers of western economics.
