题目不是说完全垄断市场嘛？

问题如下：

To find the maximizing profit:

选项：

A.

A monopolistic firm will look for best output quantity, while a perfectly competitive will look for a best price.

B.

A monopolistic firm will maximize the output, while a perfectly competitive will look for a best output quantity.

C.

A monopolistic firm will look for a best price, while a perfectly competitive firm will look for the best output quantity.

解释：

C is correct.

In a monopoly industry, the quantity demanded in unknown, therefore the firm will look for a best price to achieve profit maximizing. In a competitive market, the product price is known therefore the firm should look for their own output quantity to maximize profit.

考点：完全竞争市场和垄断市场

解析：在垄断竞争市场上，价格是变动的，因此厂商需要自主寻求一个最优价格实现利润最大化。而在完全竞争市场上，产品的价格是给定的，因此厂商只能依据该产量，不断调整生产规模，以实现利润的最大化。
