中文摘要：

分析、界定资源型城市不同转型阶段内涵及特征,构建吉林省资源型城市转型阶段识别体系。引入具有隶属函数性质的分段函数模型,识别转型阶段、分析转型特征及成因。结果表明,吉林省资源型城市经济与社会发展、基础设施建设、环境污染治理等方面转型效果均有所提升,总体进入基本转型阶段,经济转型特征最为明显,城市基础设施建设较落后。不同类型资源型城市转型效果差异显著,其中石油类城市转型较好,森工类、煤炭类城市转型较差,资源枯竭型城市较其他城市转型难度大;同时城市的资源依赖特征仍然突出。评价结果符合吉林省资源型城市实际情况。最后从中央政策、产业基础与空间区位、资源禀赋、地方财政等方面分析吉林省资源型城市转型特征成因,并提出了吉林省资源型城市未来的可持续发展模式与路径。

英文摘要：

The article defined the connotation of different transition stages and identification system of resource-based cities in Jilin Province, then introduced Piecewise function method to identify the transition stage, and analyzed the character. The result showed that, economic and social development, infrastructure construction, environmental governance improved well, and the transition of resource-based cities overall stepped into the fundamental stage. Among all indicators, economic transition effect was the best, but the infrastructure transition effect lagged behind. While the results differed obviously between different types of resource-based cities, the transition effect of oil cities was much better than forestry and coal cities, and the resource-exhausted cities were confronted with much more difficulties than others in the process of transition. Meanwhile, the resource characteristics of resource-based cities were still prominent. In general, the results coincided with the actual situation of Jilin Province. Then the article analyzed the causes of the transition of the resource-based cities from the central government policies, industrial base and spatial location, natural resources, local financial,etc. Finally, the study proposed sustainable development routes and modes of resource-based cities in Jilin Province. For example, the coal, metal, and oil cities can choose the transition routes such as comprehensive development mode, dominant industry transition mode, and continuous industry mode, while the comprehensive and forestry cities may choose the turn direction routes such as sustainable resource dived mode.
