General fractal models on structure and function of dynamic economy systems:theoretical foundations

摘要: 从经济系统的定义及其投入—产出的响应模型出发，导出具有分形性质的弹性公式和生产函数，从而揭示了ＣｏｂｂＤｏｕｇｌａｓ函数的理论来源并将其推广到一般形式，解决了经济学中一些悬而未决的理论难题－

Abstract: A reseach is made into the fractals and fractal dimensions of a dynamic economy system dX i/dt=f i(X 1,X 2,…,X n), from which the allometric relationship,X i∝X α ij j,is derived as a dynamic similarity model, where X iandX jare some kind of measurements of the ith and jth elements of the system given,α ij =(dX i/(X idt))/(dX j/(X jdt))=D i/D j,is the scaling factor, in this expression D i is the general dimension of X i and D j dimension of X i. On the other hand, on the c...
