Abstract:

Based on the knowledge and understanding of vulnerability, this article constructed a vulnerability assessment model, combining entropy value method and principal component analysis, and made a study on the vulnerability of the economic systems of mining cities in Northeast China, to discover the influencing factors and the functional mechanisms. The results indicate that most mining cities with high vulnerability are spatially concentrated in Heilongjiang Province. The mean vulnerability scores of mining cities for different mineral resources have a descending trend of coal resources > integrated mineral resources > metal resources > petroleum resources. The vulnerability scores have a tendency to increase with the development of mining citys. The sensitivity to the gradual depletion of regional mining resources and the State-owned enterprise reforms has more remarkable influence on the degree of vulnerability of mining cities. Finally, by considering the industrial structure, ownership, size scale, organizational structure, technological structure, investment structure and locational capacity, optimization and adjustment are made to reduce the vulnerability of economic systems and to achieve the sustainable development of urban economy.

Key words: entropy value method, mining city, Northeast China, principal component analysis, the vulnerability of the economic system
