Abstract: Pidgin language is a kind of hybrid and peculiar language variation. As a peripheral and nonstandard language，pidgin language was often neglected and ignored. Although linguists started to make a study on this hybrid language within linguistic field from 1950s，the social value of pidgin language hasn’t been widely accepted. Pidgin language is not perfect in pronunciation，grammar and syntax，but from the economy principle of language (this paper focuses on information exchange and expression)，pidgin language plays an important role in commercial trade because of its short structure and ability to carry more information，which has inevitably made great contribution to the global economic prosperity.

Key words: hybrid language, Pidgin language, Pidgin English, the economy principle of language, business value
