Between 1931 and 1937, Jiang Tingfu (Ting-fu Fuller Tsiang) and Xiao Gongquan (Kung-chuan Hsiao) took turn to assume the Managing Editor of the English quarterly, Chinese Social and Political Science Review. Each of them had quite a different attitude towards its editorship. Jiang actively published book reviews of newly released historiographies by Chinese authors, in addition to writing short research articles as well as helping John K. Fairbank publish his first paper. His intention was to promote internationally the history of modem China on the basis of Chinese historiographies; he would like very much to simultenuously stimulate both the Sinicization and internationalization of this field. In contrast, Xiao's ultimate concern was to dedicate himself to the study of the history and writing of Chinese political thought, though he found himself having had to respond to and to further refute the assertation of "wholesale Westernization" (Quanpan xihua) current at the time. He seemed to have lacked the sort of motivation that spurred Jiang to promote his own field overseas. He appeared passive in the position of the Managing Editor and chosed to confine himself to the editorship in a conservative sense. The contrast between Jiang's activism and Xiao's passivism shows respectively the perceptible differences in the road chosen for the Sinicization of social science(s) in 1930s. To a certain extent, their historical experiences should offer some lessons and inspire contemporary promoters of the Sinicization of social sciences.
