摘　　要：通过对区域经济系统模型的研究,确定了经济系统的分形特征,并通过实例建立投入与产出的数学模型,验证了其分形特征,利用分维确定了各投入与产出量的变化趋势,揭示了区域经济系统的复杂变化,为了解和指导区域经济发展提供了新的方法和依据。In this papers, it study on the model of the regional economy systems, ascertain the fractal characteristics of the economic system, and then found the mathematical model of input and output of the grain production system. According to fractal dimension, it explained trend of development and relation between input and output of the grain production system of Heilongjiang Province. Proved that fractal method reflected complicated changes on the economic system. In a word, it offered the new theoretical foundation and methods for knowing and guiding regional economic development.
