基于空间结构的长江经济带可持续发展关联分析

Relevance Analysis of Sustainable Development of Yangtze River Economic Belt Based on Spatial Structure

科学合理的空间结构不仅能够促进区域资源高效利用,还能够有效避免交通拥堵、住房紧张、资源稀缺等“城市病”,是区域发展的“调节器”和“助推器”。首先从规模分布、中心结构、空间联系、紧凑性四个维度选取城市规模基尼系数、城市首位度、经济联系强度、空间紧凑度四大空间结构指标对长江经济带空间结构进行测度;其次,运用优化后的Super-SBM-Undesirable模型对长江经济带可持续发展现状进行综合评价;最后,构建基于区域空间结构的可持续发展关联分析模型,并分别基于长江经济带整体视角、11省市个体视角分析长江经济带空间结构与可持续发展间的关联关系。

Scientifically justifiable spatial structure can not only promote the efficient use of regional resources,but also can effectively avoid"urban diseases"such as traffic congestion,housing shortage,resources scarcity,and so on.It is the"regulator"and"booster"of regional development.Firstly,this paper measures the spatial structure of the Yangtze River Delta Economic Zone from the four dimensions of scale distribution,central structure,spatial connection and compactness:Gini coefficient of urban scale,urban primacy,regional economic linkage strength and spatial compactness.Secondly,the optimized Super-SBM-Undesirable model is used to evaluate the sustainable development status of the Yangtze River Delta Economic Zone.Finally,a sustainable development correlation analysis model based on regional spatial structure is constructed.Based on the overall perspective of the Yangtze River Delta Economic Zone and the individual perspective of 11 provinces and cities,the relationship between the spatial structure of the Yangtze River Delta Economic Zone and sustainable development is analyzed.
