由萨维奥蒂和皮卡(Pier Paolo Saviotti and Andreas Pyka)所提出演化增长理论(SP模型)既不同于主流的宏观增长理论,也与大多数演化增长理论有所差异。它克服了传统演化增长理论无法度量质变的缺陷,并从质变推动经济发展这一论点出发,在整个宏观经济的层次上,分析了新部门创生所导致的结构变迁对经济发展的影响。该理论构建了一个新部门创生的模型,模拟了企业数量、需求、就业等一些经济发展的主要变量的曲线,并描述了模型参数变化对这些曲线的影响,其结论具有很强的解释力和现实意义。
The evolutionary growth theory (SP model) proposed by Pier Paolo Saviotti and Andreas Pyka differs from both the mainstream macro-growth theory and most evolutionary growth theories. It overcomes the defect that the traditional theory of evolution and growth can not be measured qualitatively and qualitatively, and from the argument of qualitatively promoting economic development, it analyzes the impact of structural change caused by the creation of new departments on economic development at the macroeconomic level. This theory constructs a model of creation of a new department, simulates the curve of some major variables of economic development such as the number of enterprises, demand and employment, and describes the influence of the change of model parameters on these curves. The conclusion has strong explanatory power And the real meaning.
