经济结构跃迁政策仿真研究

为了更好地反映经济结构变迁、规模收益递增等现实经济现象,新结构经济学提出了内生性生产函数的概念。而结构型生产函数是内生性生产函数的一种特例,这种生产函数由若干个规模收益非递增的生产函数通过过渡区域拼接而成,在过渡区域中可以具有局部规模收益递增的性质。结构型生产函数形式简单,而且常常可以使得相应的经济模型中存在结构型多重均衡,从而可以更细致地刻画经济现实。在存在结构型多重均衡的经济体中,仅仅依赖市场机制一般无法保证经济从低水平均衡跃迁到高水平均衡,这时就需要政府采取因势利导的经济跃迁政策。通过对经济结构跃迁政策的仿真分析可知,过渡区域位置的不同会导致结构跃迁困难程度不同。当过渡区域靠近低水平均衡时,利用高投资低消费的经济政策即可帮助经济体实现结构跃迁;而当过渡区域远离低水平均衡时,为了实现经济结构的跃迁就需要引入外部资源。

摘要: 为了更好地反映经济结构变迁、规模收益递增等现实经济现象,新结构经济学提出了内生性生产函数的概念。而结构型生产函数是内生性生产函数的一种特例,这种生产函数由若干个规模收益非递增的生产函数通过过渡区域拼接而成,在过渡区域中可以具有局部规模收益递增的性质。结构型生产函数形式简单,而且常常可以使得相应的经济模型中存在结构型多重均衡,从而可以更细致地刻画经济现实。在存在结构型多重均衡的经济体中,仅仅依赖市场机制一般无法保证经济从低水平均衡跃迁到高水平均衡,这时就需要政府采取因势利导的经济跃迁政策。通过对经济结构跃迁政策的仿真分析可知,过渡区域位置的不同会导致结构跃迁困难程度不同。当过渡区域靠近低水平均衡时,利用高投资低消费的经济政策即可帮助经济体实现结构跃迁;而当过渡区域远离低水平均衡时,为了实现经济结构的跃迁就需要引入外部资源。

Abstract:  In order to better explain the real economic phenomena such as changes in economic structure and increasing returns to scale, new structural economics proposes the concept of endogenous production function. The structured production function is a special case of endogenous production function and it is composed of several production functions of nonincreasing returns to scale which work together through transition zones. A structured production function has the property of locally increasing returns to scale in the transition area. With a simple form, it often achieves structural multiple equilibriums in the corresponding economic model, so that it can describe economic reality in more details. In those economies with structural multiple equilibriums, it is hard to ensure economic transition from a lowlevel equilibrium to a highlevel equilibrium simply by relying on market mechanisms, thus calling for governmental policies on economic transition. Through the simulation analysis of the economic structure transition policy, we come to the conclusion that transition areas with different positions will lead to different degrees of difficulty in structural transition. When a transition area is close to the lowlevel equilibrium, those economic policies that use high investment and low consumption can help the economy to achieve structural transition. However, when the transition area is far away from the lowlevel equilibrium, external resources need to be introduced in order to achieve economic transition.
