Research of non-distinct Solow economic growth model

摘要

A variety of fuzzy phenomena exist in economic systems in the realistic world, so it is of great significance to build a model with fuzzy numbers to solve them after analysis is done in research of Solow economic growth model. However, the function with fuzzy numbers is not differentiable. Moreover, the traditional operation rules can not be used to solve the fuzzy general quadrate equality. The author here first builds a non-distinct (that is fuzzy) economic growth model by using fuzzy mapping theory and by generalizing the definite economic growth model into the non-distinct case. Besides, he probes a fuzzy solution and its properties to the model. And finally, he proves the feasible generalization by a numerical example.
