甘肃省定西地区所辖的７个县均为国家级和省级贫困县。对于定西地区绝大部分农村的农民来说，邮政通信仍是覆盖面最广、价格最优惠、利用率最高的通信方式。在一些电话不通、交通不便的农村，邮政甚至是惟一的通信方式，中国邮政对社会承担的普遍服务在这里得到了最明显的体现? Dingxi area in Gansu Province under the jurisdiction of the seven counties are national and provincial poverty counties. For the vast majority of rural farmers in Dingxi, postal communication is still the most widely available, the most preferential price and the highest utilization rate of communication. In some telephone networks, rural areas with inconvenient transportation, postal service and even the only means of communication, the universal service that China Post possesses to society is the most obvious manifestation here.
