徐州都市圈工业结构转型及其影响效应分析

在GIS空间分析技术支持下,采用工业结构转型相关指数方法,深入分析了2000~2012年徐州都市圈工业结构转型的时空演化特征及其对区域发展的影响效应。发现：近10 a来徐州都市圈工业转型速度、高级化呈较快提升趋势,且与工业经济增长明显相关,但合理化程度下降;竞争优势行业和主导产业均呈向资本技术密集型行业演化趋势,但主导产业的支撑作用有待增强;空间上呈现先集聚后扩散趋势,不同行业空间集聚程度各异,形成了沿东陇海工业集聚发展轴;工业专业化分工呈现以徐州为核心向外技术水平下降的圈层式垂直分工格局;工业高级化和区域工业占有率对经济增长促进作用显著,而对能源消耗和工业SO₂排放抑制作用明显,但不同尺度区域影响存在差异。

Industrial Structure Transformation and Its Influence Effect in Xuzhou Metropolitan Area

Using the Correlation index of industrial structure transformation, the temporal and spatial evolution characteristics of industrial structure as well as the effects changing on regional development are explored with the spatial analysis of GIS from year 2000 to 2012 in Xuzhou Metropolitan Area. The results show as follows： in the recent 10 years, the speed and optimization of industrial transformation showed an increasing trend which had a positive impact on economic growth, while the degree of industrial structure rationalization decreased. The capital and technology intensive industry gradually played a dominant role in the superiority industries and leading industries, and the supporting role of leading industries need to be enhanced. The spatial distribution of industry evolved from agglomeration to diffusion, forming the development center along the East Longhai. The degree of spatial agglomeration performed different among industrial departments. Industrial specialization showed an obvious difference. The technical level of Xuzhou was higher than the peripheral region which presented a circle layer pattern. The positive impact of industrial optimization and share on economic growth was significant. Furthermore, it considered that industrial optimization and share both contributed to the reduction of energy consumption and sulfur dioxide emissions. The impact on region of different scale was different.
