我们知道,“完全竞争”的状态必须符合四个条件;一,市场上有无数的买者和卖者,他们都是市场价格的被动接受者,无力影响市场价格;二,每个厂商的产品均无任何差异、可以完全互相替代;三,厂商无须任何成本就可自由地进入或退出某一行业;四,市场信息完全畅通,每个人都是完全知情者。 要满足这四点,才算“理想状态下的完全竞争”。在这样的状态下,单个厂商根本没有能力改变成交的价格,他们是完全被动的,因此叫做“价格接受者”。 We know that the state of “perfect competition” must meet the following four conditions. First, there are innumerable buyers and sellers in the market who are both passive recipients of market prices and unable to influence market prices. Second, each manufacturer's products All without any difference, can completely replace each other; Third, the manufacturer without any cost can freely enter or exit an industry; Fourth, the market information is completely smooth, everyone is completely insider. To meet these four points, be considered “perfect competition in an ideal state.” In this state, a single manufacturer simply can not afford to change the price of the transaction, they are completely passive, so called “price taker.”
