经济学是研究什么的科学呢?目前西方普遍认可的“经济学”定义是:“我们如何进行抉择,来使用具有各种可供选择的用途的、稀缺的生产资源来更好的满足既定的目标——生产什么样的物品、如何生产和为谁生产,现在生产还是将来生产?” 从这个定义本身来看,（西方）经济学是属于规范经济学范畴的,即研究经济体系应该如何运行,资源应该如何配置。但是细究一下,我们会发现隐藏在这个定义背后的更深刻的一个含义,即:经济体系是如何运行的?为什么会这样运行?这样运行的后果是什么?也就是实证经济学的问题。所以经济学首先属于实证经济学的范畴,在此基础上才产生了规范经济学。
What is the science of economics? What is the commonly accepted definition of “economics” in the West ?: “How can we make a decision to use scarce production resources of various options to better meet the established Goals - what kind of goods to produce, how to produce, and to whom, to produce now or in the future? ”From this definition, (Western) economics belongs to the field of normative economics, that is, to study how the economy should operate How resources should be configured. But a closer look reveals a deeper implication hidden behind this definition: How does the economy operate? Why does it work? What is the consequence of this operation? That is, the problem of empirical economics. Therefore, economics first belongs to the category of empirical economics, on the basis of which only produced normative economics.
