面向经济复杂性的行为建模与计算实验及应用研究

The important theoretic contribution of behavior and experimental economics focuses on the broad existence of cognitive behavioral bias with significant effect. Basing on deepening multi-attribute analysis of behaviors including heterogeneity and interaction, and by means of observation or experiment and making the obtained datum from real behavior parameterization with cardinal, ordinal number variables styles as well as distributional vectors, then introducing and incorporating them into classical decision-making model, and breaking through the RA (Representative Agent) analysis framework, for constructing the integrated model with behavior-through and macro-micro link feature as the experimental platform; With the cross matching simulation between multi-scenario, multi-state and multiple dimensions of behavioral properties, and to explore the inner relationship between microscopic behaviors and macroscopic phenomena and their interacting mechanism, and how to affect inversely the individual decisions, and it is greatly benefit for revealing the essence of an increasingly complex economic and financial activities from the source. There will be some new contributions in this research project in the endogenous parameterization of key behavioral characteristics, the behavioral relationships between individual and group, and conducting experiments by human subjects combined with virtual subjects methods etc., for promoting the traditional game experiment and econometrics methods as well as empirical positives. It is realizable to visually and interactively evaluate and foresee the policy effect, and to deal well with the interacting roles between the market-determine and the change of government's function, to provide more powerful and reliable decision-support, and to blaze a new path of exploring the humanistic nature of complex economy with interdisciplinary. At last, it is helpful, taking salary incentive of heterogeneous employees, the relationship between investor's behaviors and the complicated volatility of stock market as illustrating examples, to show the validity of applying behavior modeling and computing experiment.
