On April 26, the School of Finance and Economics and Jiangsu Statistical Science Research Base successfully held a lecture on "Basic Principles of Input-Output Analysis and Its Application in Marxist Economics Research" at Sanjiang Building 0701. Professor Zhang Zhongren of Shimane Prefectural University of Japan was invited as the guest speaker in this lecture. The lectures were attended by associate professor Li Fanglin, chairman of the Department of Statistics, all the teachers of the Department of Statistics and undergraduates and postgraduates of the School of Finance and Economics. The lecture was chaired by Professor Yao Hongxing, Vice Dean of School of Finance and Economics, Jiangsu University. Professor Zhao Xicang, head of Jiangsu Statistical Science Research Base and head of Jiangsu University, participated in the relevant discussions.

In the lecture, Professor Zhang Zhongren introduced three main sources of input-output theory based on his own research experience for many years: Queenay's Economic Table, Marx's two major categories reproduction schema and Walras'general equilibrium theory; expounded the premise of input-output analysis, i.e. input-output table, derived the value determination model from the physical table, and how to deal with the two major categories. The correct expression of the input-output table and the confusion of the roles of invariant capital and variable capital and its impact are discussed in detail. On this basis, the paper summarizes that the input-output table provides an analytical framework for value determination, and discusses that the input-output table can not be directly used to analyze reproduction problems.

At the end of the lecture, the teachers attending the lecture had a warm and in-depth exchange with Professor Zhang Zhongren on the relationship between input-output and Marxist economics and the latest development of input-output theory. In the process of communication, it further broadens the academic horizon of teachers and students, and provides better thinking for teachers and students to better understand input-output theory and Marxist economic theory.
