略论经济系统的两种演化机制

On the two evolutionary mechanisms of economic system

界定了经济系统演化中的自组织与达尔文主义,并认为它们在经济系统中演化时同时存在。自组织理论是方法论,其对应的自组织机制作用周期较短;广义达尔文主义是本体论,对应的“自然选择机制”作用周期较长。实现这两种机制在计算机仿真过程中较为容易,但仍存在一些理论困难:选择单位的界定;对理性概念的反思;模型过于复杂;存在演绎主义的意味。

This paper gives definitions of self - organization and universal Darwinism in economic systems. It suggests that both mechanisms exist in the evolution of economic systems. Self - organization theory is methodological and its corresponding mechanism takes effect in a short time. Universal Darwinism is ontological and its corresponding mechanism takes effect in a long period. It is easy to implement the two mechanisms in models of computer simulation. However, some difficulties remain： the determination of the unit of selection ; the reflection of rationality; the models built are too complicated; whether this approach is Deductivism.
