摘要
完全竞争市场的一项重要行为结果是厂商以及行业之间都获得均等的零利润,而现实中任何偏离完全竞争市场假设条件的情况都有可能导致利润的差异。现代产业组织理论认为,在评价利润差异时需要判断对完全竞争哪些假设的偏离是合理并有效率的,那么由这种原因所导致的利润差异也即是合理并可以接受的,而那些不合理的偏离原因所带来的利润差异则是我们应该尽量避免的。
An important result of perfect competition market is that every firm and every industry will get the identical zero-nrofit. Any departure from the hypotheses of perfect competition market will lead to the difference of profit. Modem theory of industrial organization asserts that we should judge which biases form the hypotheses are reasonable and efficient when we analyze the difference of profit, and accordingly this kind of biases are acceptable. However, We should try to avoid the difference of profit which comes from the unreasonable departure.
