Dans l’histoire de la République de Chine, Tsiang Tingfu était un historien et un critique politique, en même temps, il était un politicien représentatif dans la grande vague des « experts en politique ». Ce mémoire se concentre sur sa pensée et ses expériences dans la première moitié de sa vie. Pendant cette période, Tsiang a présenté les caractères de la maturité et l’activité dans sa pensée. En particulier, dans les années de 1930, il a déjà préconisé la pensée la plus importante qui a provoqué un gros débat entre les intellectuels chinois. Au travers des expériences de Tsiang de suivre les études, on fait ressortir que la culture traditionnelle chinoise et la nouvelle éducation occidentale ont conjointement influencé sa pensée. Dans ce mémoire, on analyse ses opinions et ses pratiques en politique et trouve que les noyaux de sa pensée consistent au nationalisme et à son intention de la modernisation chinoise. Au fur et à mesure de l’aggravation de l’invasion japonaise en Chine, la sauvegarde de la nation a occupé la position centrale dans ses opinions, et sa pensée a été devenue conservatrice. En 1935, stimulé par son sens de responsabilité comme un intellectuel, Tsiang a participé au gouvernement nationaliste chinois et a servi ce régime jusqu’à sa retraite. / Tsiang Tingfu was a historian and political critic. In the history of the Republic of China, he was also a representative politician in the wave of "scholar-bureaucrat". This thesis focuses on his thoughts and his experiences in the first half of his life when Tsiang exhibited characteristics of maturity and activity in his thinking. In particular, in the 1930s, as one of the leaders of the public opinion in China, he had advocated most of his important thoughts which triggered a heated discussion among the Chinese intellectuals. Through investigating each step in his educational career, we come to the conclusion that both the Chinese traditional culture and the Western education had shaped his later political and social thinking. By examining his principle political thoughts and his social practices, it is also found that the core of his thoughts lies in the nationalism and his intention of Chinese modernization. As the Japanese invasion intensified in China, saving the nation became his superior value and his thought therefore turned to the conservative. In 1935, prompted by the sense of responsibility as an intellectual, Tsiang participated in the Nationalist government and had served it until his retirement.
