language promotion institutions(LPIs)are devoted to the overseas spread of the mother-tongue language and culture,and have the two characteristics of nationalism and transnational opera-tion.In their regular management and daily operation,LPIs need to deal with the upper-level relation-ship with the government and the lower-level relationship with their overseas branches.This paper transposes the two relationships into the management model and the operational model in order to construct and interpret the four types of their development models:A.the private-operated-commer-cialized management model.B.the private-operated-non-commercialized management model.C.the state-operated-non-commercialized management model.D.the state-operated-commercialized manage-ment model.The paper gives a case study of 16 LPIs like British Council and Alliance Française,and analyzes their development models.It has the following conclusions:firstly,the quantitative distribution of the four kinds of international language promotion institutions is characterized by C>D>A>B;most LPIs follow the state-operated-non-commercialized management model;the commer-cialized management model is the orientation of the reform of these LPIs.As language promoters,LPIs should not only carry out constant innovation and improvement in their management and operation but also choose the most suitable development models that are in line with the government's language awareness,their language situations and the trend of their language spread.
