　　The afternoon session was chaired by Associate Professor Yi Chen, Assistant Dean of SEPKU. Professor Justin Yifu Lin from Peking University made a keynote speech on “70 Years of China’ s Economic Development and Its Implication for Modern Economics”. Professor Lin pointed out that China’s developmental experience during the past seventy years could bring new ideas to modern economics. He emphasized the necessity of economic theoretical innovation, as an example of which, New Structure Economics believes in the endogenous industrial structure at different developmental phases, and industry with comparative advantages can be transformed into that with competitive advantages through certain system arrangements, serving as the best developmental structure. Lastly, Professor Lin encouraged young scholars to conduct research on new structure economics and make theoretical innovations.

　　In the afternoon, the seminar was chaired by Professor Xuezheng Qin, Associate Dean of SEPKU. Firstly, Professor Joel Sobel, UCSD, delivered a keynote speech themed at “Functional Language in Games”. During his lecture, Professor Sobel gave an introduction to three philosophers of language, namely, H.P. Grice, John Austin, and Roman Jakobson, illustrated their achievements in the study of language communication, analyzed how to integrate functional languages into economic models, and offered vivid examples in the strategic decision of cheap-talk. From his perspective, inspired by philosophy and linguistics, Game Theory may probe deeper into the functionality of languages.
