Economics (经济学) is the study of how societies with limited resources decide what to produce, how to produce and for whom to produce. What, how, and for whom to produce are problems all over the world because human needs are practically unlimited, but all societies have only limited quantities of resources that can be used to produce goods or services.

A knowledge of basic economics is important for understanding both the problems and opportunities that will face the world economy in the 21st century. As a student of economics, one will have the chance to discover how commerce(商业), government policies, and day-to-day decisions made by consumers affect his living standards. The study of economics can help him understand the influence of such events as the move to free markets in Poland and Russia, or of ups and downs in interest rate and the foreign exchange rate. Economics is influenced by developments in the many different areas of business, politics, science, nature, religion and history.
