考虑到传染病的传播与股民数量的增长之间的类似性,建立了刻画新增股民数量变化规律的数学模型,并进行了相应的数学实验.建立的模型较好地反映了短期内新增股民数量的变化规律.%Considering the similarity between quantitative increment of retail investor and infectious diseases, we establish a model for retail investor which describe the changing rule of its increment. Furthermore, the results of numerical experiments illustrate that our model shows the changing rule of retail investor in the short term.
