Polynomial Fitness Simulation of Chinese New Stockholders

This paper studies the relationship between amounts of new stockholders and share index in Chinese stock market. We analyze behavior characters of investors, construct a model to forecast the amounts based on polynomial fitness such as quintic, nine times’, eleven times’ polynomial fitness ordinally. Comparing with factual data, we apply polynomial simulation method to review the fitness of model, and confirm sensitivities of thedata. The result proves the validity of the simulation method.
