Statistics from the immigration personnel at various frontier stations and from national surveys of domestic tourism ( of the ratio of citizens touring ) are especially incompatible with survey statistics of local tourism . a failure to recognize this would create a severe problem of omission
特别是全国的各边防站入境人员统计和全国的国内旅游调查(即居民出游率调查) ，就不适合地方接待游客的调查统计，否则会出现严重遗漏的问题。
