| There are four basic types of
competition in business that form a continuum from pure competition through
monopolistic competition and oligopoly (商品供应垄断) to monopoly. At one end of the
continuum, pure competition results when every company has a similar product.
Companies that deal in commodities such as wheat or corn are often involved in
pure competition. In pure competition, it is often the ease and efficiency of
distribution that influences purchase. In contrast, in monopolistic competition several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts (折扣) are often used as part of a marketing strategy to influence sales. Oli A. a product or service B. competition C. revenue D. oligopoly [简答题]争当优秀站点管理员的基本要求是什么？
