资源约束下的三元函数区域增长模式

A regional growth model of ternary variables binding by resource

区域经济动力学的核心问题是区域增长,本文将资源要素引进生产函数,建立了资源约束下的三元区域增长模式,研究揭示:(1)模式不仅可以较好地模拟区域发展的不同阶段,还可以较客观地描写、预测区域发展与环境资源等区域因素的关系;(2)在区域经济(区域社会生产)这个经济“大木桶”里,起到主要约束作用的因素是资源,而不是通常备受关注的资金或管理因素;(3)资源指数越小越有利于区域资本的积累和社会生产总量的增加。

The key problem of the regional economic dynamics is the economic growth. As the resources shortage issue had not been fully realized,the binding force and the carrying capacity of resource to labor （population） and regional economiy were not taken into consideration in the classical theory of regional growth. Based on Rabenau and Miyao＇s modern economic growth models, a dynamical regional growth model of ternary variables binding by resource, in which the labor, capital, environment capability and efficiency of management are taken as the regional growth elements, is set up in this paper. The analysis of equilibrium states shows that the regional economic growth （Gross National Product） is proportional to two factors, one is the abundance degree of the resources and environment, the other is the summation of management efficiency, capital in- vestment, science and technology, and labors. It is obvious that natural resource and environment instead of the granted capital, technology or labor are the bottleneck factors in the regional economic cask. In practical production, management, capital, technology and labors are compensatory and balanceable in the economic development while environmental resource is fatal. The results of the study by a series of analysis and numerical simulations show. （1） The model can be used not only to simulate the different stages of regional growth, but also to discover the relations between the regional growth and the economic factors; （2） natural resource and environment instead of the granted capital, technology or labor are the bottleneck factors in the regional economic cask; and （3） the bearing capacity of environmental resources will play an important role in the social gross output value.
