摘　　要：科学的经济学研究是通过理论模型和经验实证实现的。理论模型的内涵至少包括三个方面的内容:提出理论模型的背景(或曰模型的约束条件)、理论观点本身和以数学模型等为载体的艺术表现;科学的理论模型只有通过"双重的"逻辑实证和经验实证才能得到证明。在理论模型的诸多解释变量中,要找出其中关键的外生变量。以外生变量作为切入点,方可提出所研究问题的实际解决之策,使经济学的研究成果不仅具有传统意义上的"解释功能"、"预测功能",而且具有实践意义上的"政策功能"。惟如此,才能真正完成科学的经济学研究———提出问题、分析问题、解决问题———的全部探索过程和经济学所固有的"经世济民"的历史使命。A scientific study of economics is done by a theoretic model and empirical verification. A theoretical model contains at least three elements, including background of the theoretical model （ or restrictive conditions for the model） , the theorized point itself and artistic representations in form of mathematic model and the like. Mo- reover, a scientific theoretical model cannot be verified but by a ＂double＂ process of logical verification and empiri- cal verification. In the process of verification, the key exogenous variable must be discovered from among the many explanatory variables of the model. Only in terms of the exogenous variable can a practical solution to the problem be put forward, which will offer results of economic study with ＂explanatory function＂ and ＂predicting function＂ in a traditional sense and ＂policy function＂ in practice. It is only by this means that a real scientific economic study, which has to go through the steps of raising, analyzing and solving the problem, can cover a complete process of exploration and fulfill its historical mission of ＂stabilizing society and consoling people＂.
