一、经济学的素描在一个现代经济社会中,经济科学试图对人们的购销行为(包括品种和数量),商品劳务价格以及税收和政府开支对经济的影响作出解释。而仅仅在这很少的几句话中就包含了数不清的各类行为和现象。人类不仅购销那些能立即带来满足的、诸如食品之类的商品,而且也进行工厂、机器设备等生产资料的交易,它们只会在将来一定时间带来产品和收入。另 I. A Sketch of Economics In a modern economy and society, economic science tries to explain the economic impact of people's buying and selling behavior (including variety and quantity), prices of goods and services, and taxes and government expenditures. And just a few words in this very few include a variety of types of behavior and phenomena. Humans buy and sell not only those commodities that immediately bring satisfaction, such as foodstuffs, but also the trading of the means of production, such as factories, machinery and equipment, that will bring about their products and revenues for some time in the future. another
