还和我扯起科学来了，不错，有意思。那我问你，没有牛顿的经典力学理论做基础，会有后来爱因斯坦的理论吗？而且爱因斯坦是搞量子力学的吗？到底是谁不懂，谁又在偷换概念？
Economics (/ɛkəˈnɒmɪks, iːkə-/)[1][2][3] is the social science that studies the production, distribution, and consumption of goods and services.[4]
Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyzes basic elements in the economy, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyzes the entire economy (meaning aggregated production, consumption, savings, and investment) and issues affecting it, including unemployment of resources (labour, capital, and land), inflation, economic growth, and the public policies that address these issues (monetary, fiscal, and other policies). See glossary of economics.
Other broad distinctions within economics include those between positive economics, describing "what is", and normative economics, advocating "what ought to be"; between economic theory and applied economics; between rational and behavioural economics; and between mainstream economics and heterodox economics
帖一段英文的定义你自己看，我不知道您是在那读的经济学本科。如果是国内的经济学本科这样教经济学的话，我真的对国内的经济学教育感到担忧。甚至还不如你前面自己得出的关于经济学与政治经济学方面的见解，只能说你最后选择学法律是对的！
