由于经济系统与生态系统存在类质同像性,因此可应用源自生态系统的上升性理论来定量描述经济系统的增长与发展.在简单介绍了上升性理论的基础上,以关中-天水经济区铁路客流为例,对区域经济系统的上升性及其相关指标进行了计算.研究表明:2002—2006年的5 a间,关中-天水经济区的系统总吞吐量、平均相互信息、上升性指数、可持续发展能力和系统的多样性等5项指标均保持增长态势,由此判断关中-天水经济区处于经济系统进化的初级阶段.针对该区域经济系统中存在的自组织程度低下、结构失衡等与系统进化质量相关的缺陷提出了政策建议.
As the economic system and the ecosystem exist the similarities, it can be used to describe the growth and development of the economic system quantitatively by using the asymptotic theory originated from the ecosystem.On the basis of simply introducing the ascending theory, taking Guanzhong-Tianshui economy As an example, the rising of the regional economic system and its related indicators were calculated.The results show that the total system throughput, the average mutual information, the rising property of the Guanzhong-Tianshui Economic Zone during the five years from 2002 to 2006, Index, sustainable development ability and diversity of the system all maintain the growth trend, and thus judge Guanzhong - Tianshui Economic Zone in the initial stage of economic system evolution.Aim at the low level of self-organization in the economic system in the region, the structure Imbalance and other defects associated with the quality of evolution of the system made policy recommendations.
