资源型城市城镇化发展对我国城镇化水平的贡献性

为定量研究资源型城市城镇化水平及其对中国城镇化发展的贡献性,以全国126个地级市(仅限大陆地区)资源型城市为研究对象,分析改革开放以来资源型城市城镇化发展的基本情况,并籍此为基础研究资源型城市城镇化发展对我国城镇化发展的贡献。结果表明:1)四大区域资源型城市城镇化水平发展不平衡,东北地区城镇化率始终保持领先,但增长幅度最小,东部地区城镇化率增长最快,各地区年均增长率呈下降趋势,增速放缓;2)地级市资源型城市城镇化发展对我国城镇化发展的贡献度为0.48～0.90,其中0.79%资源型城市城镇化对我国城镇化贡献度为中,40.48%资源型城市城镇化对中国城镇化贡献度较高,58.73%资源型城市城镇化对我国城镇化贡献度高;3)类型上,均有超过各自总量50%的非金属、金属、煤炭和油气型资源型城市城镇化对我国城镇化的贡献度高,而森工型资源型城市城镇化对我国城镇化贡献度高的城市数量不到其总量的1/3;空间上,东和中部地区资源型城市城镇化对我国城镇化发展贡献度大于东北地区和西部地区。资源型城市城镇化推动了我国城镇化发展,但资源型城市的不同类型和区位,对我国城镇化的贡献度有差异。

Contribution of resource-based city urbanization to China's urbanization

To quantitatively study the resource-based city urbanization level and its contribution to the development of China urbanization, a total of 126 national resource-based prefecture-level cities(mainland China only)are taken as the research object. The basic situation of the resource-based city urbanization development since the reform and opening-up is analyzed and based on the results, the contribution of the urbanization development of resource-based cities to the urbanization development of China is investigated. The result shows that: 1)The urbanization levels of resource-based cities in four regions are unbalanced. The urbanization rate in northeast China keeps a leading level but has the lowest growth rate. The urbanization rate in eastern China is the fastest, but the average annual growth rate in all regions is in decline and the growth rate is slowing down. 2)The contribution of urbanization development of resource-based prefecture-level cities to China''s urbanization development is between 0. 48 and 0. 90. Among them, 0. 79% of resource-based cities have medium contribution to China''s urbanization, 40. 48% of resource-based cities have relatively high contribution to China''s urbanization, and 58. 73% of resource-based cities have high contribution to China''s urbanization. 3)In terms of resource types in resource-based city, the resource-based cities with metalloid, metal, coal and oil-gas which account for more than 50% of their respective total, show high contribution to China''s urbanization. While the number of forest resource-based cities has a high contribution to China''s urbanization, which is less than one third of the total. In terms of spatial distribution, the urbanization of resource-based cities in the east and central regions contributes more to China''s urbanization development than that in the northeast and western regions. The development of China''s urbanization has been promoted by the urbanization of resource-based cities, and different types and locations of resource-based cities have different contributions to China''s urbanization.
