| 摘 要： | 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.

| Abstract: | Owing to the isomorphism between economic systems and ecosystems,it is appropriate that the growth and development of economic systems is quantified and described with the ascendancy formula from ecosystems study.The Guanzhong-Tianshui economic region is one of 3 economic regions in West China which is built by central government and developed strenuously in the outline of the 11th five-year plan for development of the west region.Based on introducing the ascendancy formula briefly,as a case of railway pass... |
