Taking social-economy as an evolving complex system is to grasp the core discipline of social-economy system, analyze practical social-economic problems and provide theoretical and empirical basis for administrative decision. Therefore, we conduct research mainly on the micro basis of macro-economics, financial system evolution and financial engineering, education and human resources, game theory and mechanism design, etc. 

Financial market dynamics

Financial market is a typical system with multi-agent interaction. Thus, understanding the stylized facts and formation mechanism of financial market is not only important in economic study but also crucial for concluding and testing research method in systems science. Specifically, we study the description and formation mechanism of non-equilibrium phenomenon such as bubbles and collapses, the impact that group-interaction, such as herd behavior and cascade process, has on market macro phenomenon, the impact that prospective self-actualization and self-destruction have on systematic evolution behavior, as well as the formation mechanism and prevention and control strategy of financial systematic risk, etc.

Education economic system analysis

Human recourse and education economic study is not only an advantage of BNU, but also accords with the demand of social and economic development in China. It is a joint point of systems science, economics and science of public management, etc. We study the dynamic process of human capital accumulation and the human capital accumulation in China, put forward the concept of average education attainment, improve the human capital evaluation method with this concept, and also discuss the impact that mechanism and time course of human capital increment has on educational input.

The micro basis of macroeconomics

A major objective of socio-economic systems analysis it to establish set the micro basis of macroeconomics, namely combine the macroeconomic operation with the micro-individual optimization decision. Therefore, we analyze how optimizing behavior of microeconomic individual affect the velocity of money so to explore the bridge between micro and macro. We also put forward the concept of “holding time” so to establish money exchange model and analyze the effect of debt on velocity of money.

Game theory and mechanism design

Game theory is a basic research method to study multi-agent systems with conflict of interest. Mechanism design is a basic approach to solve many problems of multi-agent social-economic system. According to the game theory, different mechanisms bring about different behavior models of individual. Therefore, searching for the matched mechanism for expected behavior model can help understand and manage the socioeconomic system. In this aspect, we focus on the group game and do some fundamental research on quantum game.
