这三者是不尽相同、互有交叉的概念。经纪人是在经济活动中出现的角色,他是以获取佣金为目的,为买卖双方实现市场交易而从事沟通、服务的中间人。所以,应该说,经纪人是中间人的组成部分。像会计事务所、婚姻介绍所都是中介组织,但是前者不是靠佣金来谋生,后者所从事的不是买卖交易活动,所以他们都不是经纪人。 These three are not the same, the concept of overlapping. Broker is the role of economic activity, he is in order to obtain commissions for the buyers and sellers to achieve market transactions and communication, service brokers. So, it should be said that brokers are an integral part of the middleman. Like accounting firms, marriage agencies are intermediary organizations, but the former does not rely on commission to make a living, the latter is not engaged in trading transactions, so they are not brokers.
