摘要
矿业城市经济系统脆弱性是关于敏感性和应对能力的一组函数关系式,而其应对能力的影响因素很多,为了实现指标降维和客观赋值,借助主成分分析法和熵值法来简化运算;并构建脆弱性评估模型,以辽宁主要矿业城市为样本进行脆弱性评价。结果表明:(1)矿业城市经济系统脆弱性随其生命周期的推进而逐渐增大,侧面说明经济发展对资源具有高度的"路径依赖"及其产业结构的单一;(2)经济系统面对资源枯竭、国有企业改组改革扰动的敏感性对决定其脆弱性程度作用更为显著;(3)所选样本城市中,阜新市的脆弱度最高,鞍山最低,且在地域分布上呈现出辽东<辽西的趋势。最后依据脆弱性特征将案例城市划分为3种类型。
On the basis of understanding the vulnerability of economic systems, which is considered as functional relationships between sensitivity and coping ability, this article, by constructing a vulnerability assessment model and combining with Entropy Value Method and Principal Component Analysis, made a research of the economic systems' vulnerability of the major mining-cities of Liaoning Province. It shows that: ( 1 ) the vulnerability of economic systems of mining-cities gradually increasing along with their lives-cycles, from the side, it's also shows that economic development has a highly "path dependence" on resources and the industrial structure is single; (2) the sensibility of economic systems facing the disturbances of resource depletion and state-owned enterprise reform plays a more prominent role on the vulnerability of economic systems of mining cities; (3) the degrees of the vulnerability of the economic systems on selected cities, Fuxin's is the highest, while Anshsan's is the low- est; From the average scores of the vulnerability, it shows that: the east area of Liaoning's 〈 the west area of Liaoning's. At last, according to the features of vulnerability, divide the cases into three types.
