单项选择题
An analyst does research about characteristics of market structures. Excess capacity in perfect competition is most likely:（）
A. less than that in monopolistic competition.
B. equal to that in monopolistic competition.
C. greater than that in monopolistic competition.
答案
参考答案：A
解析：
垄断竞争市场中，企业的需求曲线是向下倾斜的，而且需求弹性较大。与完全竞争市场相比，垄断竞争市场中企业会提高价格并减少产量，从而造成剩余的产能，而完全竞争市场中企业会充分地利用资源，没有剩余的产能。
