【Abstract】 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.更多还原
