区域经济系统研究中的动力学方法与模型

The method of dynamics and model in the study of regional economic system

为了能对区域经济系统(RES)结构进行深层剖析,对运行特征有一定程度的定量把握,引入了系统动力学(SD)方法,以便能够探讨RES的结构特征和运行机制,并构建了RES的状态空间数学模型.

Regional economic system (RES) is a kind of high level,nonlinear and complicated system which has dynamic state behaviour.Its border is vague,and has multi-duplicate feedback ring,among each subsystem of the system and various element of every subsystem,there are unthinkable interdependent relations.So it is very difficult to analyse the development of RES only according to audio-visual knowledge,experimental judge and brain derivation,sometimes it is even impossible.In order to analyse its structure deeply and master its moving characteREStics to some extent,in this paper,the authors introduce system dynamics(SD)method to inquire into the structure,and operating mechanisms of RES,and establishing RES state space mathematic model.
