The Evolution and Coping Timing of Economic Vulnerability of Mining Cities: A Case Study in Northeast China
基于可持续科学中的脆弱性分析框架，以中国东北矿业城市为例，研究了经济脆弱性的演化过程（呈倒U型曲线）和应对时机，发现大规模爆发前采取积极措施能有效缓解负面影响。
As one kind of cities facing serious economic sustainable development problems, the economic development of mining cities possesses typical vulnerable characteristics. Based on the vulnerability analysis framework in sustainability science, the paper investigates the evolution and coping timing of economic vulnerability based on a case study of mining cities in northeast China. As exemplified by the case study, along with the growth, decline and revitalization of mining cities, the degree of economic vulnerability follows an inverse-U-shaped curve during the evolution process, which can be divided into three periods: latent period(1949-1980), outbreak period(1980-2003), subsided period(2003-). Examples of Daqing and Fuxin show that different timing for coping economic vulnerability can produce different impacts on the evolution process of economic vulnerability. Adopting active coping measures before the massive outbreak period can effectively alleviate the negative effects of economic vulnerability on the economic development of mining cities, and smoothly advance the adaptive transformation of urban economic development pattern.
