问题如下:
Which of the following businesses is least likely to have network effects?
选项:
A.A telephone company
A price comparison website for travel airfares
A resume preparation service for online job seekers
解释:
C is correct. The resume preparation service benefits from the network effects on various online job sites, but the service is not the source of those network effects.
Each of the other businesses (A, B) becomes more valuable to its customers as it attracts users.
The telephone network is very useful because most people are on it.
An airfare price comparison website is valuable to airlines because it has many shoppers and valuable to shoppers because it features prices for multiple airlines and routes.
网络效应的本质是用户越多,用户的价值越高。
B是指价格比对网站,大家用的越多,用户之间没有互动,增加了什么价值呢,或者说10个人用价格比对网站,和10000个人用价格比对网站,这两个数量的人数值有什么很大不同吗 ?
C也是不懂。
