经济学并不适合照搬自然科学的建模方法,因为经济学的研究对象是受价值判断影响的复杂现象。复杂性源于经济学的研究对象不仅具有事实和价值两个维度,并且价值的维度相对于事实的维度更具根本性。价值的这种重要性已经被行为经济学和实验经济学的结果所证明,且符合我们日常生活的常识。价值维度对于经济学有重要的科学哲学含义:第一,逻辑实证主义所提出的事实与价值的二分法在经济学中是无法成立的。第二,经验检验并不是经济学理论的压倒性评价标准。第三,经济学可以做出的预测只能是模式预测。
Economics is not suitable for copying the modeling methods of natural science, because the object of economics is the complex phenomenon influenced by value judgments. The complexity of the research object from economics not only has the two dimensions of fact and value, but also the value dimension is more fundamental than the fact dimension. This importance of value has been demonstrated by the results of behavioral economics and experimental economics and is consistent with the common sense of our everyday lives. The value dimension has important scientific philosophical implications for economics: first, the dichotomy between the facts and the values proposed by logical positivism can not be established in economics. Second, empirical testing is not an overwhelming standard of evaluation in economic theory. Third, the predictions that economics can make can only be mode predictions.
