Abstract: From 1927 to1949, the National Government tried to promote the nationstate building by the ideologies and strategies of "Three People's Principles", "Nationalism", "Fighting the War and Building the Country" and "CounterInsurgency general mobilization". During this period, a group of Nationalist Party officials, intellectuals and professionals from different fields laid an important foundation for the film communication of National Government through various ways of mail declaration, lectures, article publishing and personal practice. Meanwhile, the National Government and its related departments and organizations at all levels released letters, rules, creeds and proposals on film censorship, literature and art award and cultural development and literature and art propaganda and established Film Censorship Committee, Film Guidance Committee and related rules, regulations and standards. Through all these measures, the National Government intended to selfcriticize the feudal ethics of national films, boycott the humiliating ways to China of European and American films, guard against the "revolution" thoughts of Soviet Union's films and eliminate the "class" consciousness of leftwing films and exercise the central government's missions and responsibilities in film communication with the positive attitudes of "party education" and "cultural control". Due to various reasons in political, military, economic, ideological and cultural aspects, the film communication system of National Government failed to reach the expected depth, breadth and efficiency.

Key words: National Government, film communication, political party propaganda, nation-state building
