一个市场的收入分状况

人均国内生产总值

What are per capita income and per capita GDP?

why do people often look at the income level to assess the potential of a market?

That the income gap between high-income and low-income countries has grown wider is a matter for concern. And the number of the world's citizens in abject poverty is deeply disturbing. But it is wrong to jump to the conclusion that globalization has caused the divergence,or that nothing can be done to improve the situation. To the contrary:low-income countries have not been able to integrate with the global economy as quickly as others,partly because of their chosen policies and partly because of actors out of their control.

国民生产总值和国内生产总值体现了一个国家的全部收入，在衡量国民收入方面可以互换使用。

商界人士非常关心一个市场的收入分布状况，因为如果在低收入国家他们就要以生产价格低廉的大路货为主。
