问题 Monopolistic competition differs from perfect competition primarily because______.

选项 A、in monopolistic competition, firms can differentiate their products
B、in perfect competition, firms can differentiate their products
C、in monopolistic competition, entry into the industry is blocked
D、in monopolistic competition, there are relatively few barriers to entry

答案A

解析 答案为A项。monopolistic competition“垄断竞争”,如餐饮业。其特征为:产品既存在差异性又存在替代性;存在大量厂商(至少50~100家);进入障碍不显著。产品差异性把它和完全竞争区分开来。故本题选A项。
