基础设施投入效率时空演变及其关联格局研究——基于中国地级以上城市的实证

城市基础设施效率研究是科学评价基础设施发展质量的重要环节.在构建城市基础设施投入效率评价指标体系的基础上,借助MaxDEA软件,运用DEA模型,对2006-2016年中国地级以上城市基础设施投入产出效率进行测度和分解,探究其时空演变特征,并通过ESDA方法分析其空间关联格局.研究结果显示:①中国城市基础设施的总体投入产...

Spatial-temporal Evolution of Infrastructure Investment Efficiency and Its Correlation Pattern Based on the Empirical Study of Prefecture-level Cities in China

The research on the efficiency of urban infrastructure is an important part of the scientific evaluation of the quality of infrastructure development. On the basis of constructing the evaluation index system of urban infrastructure input efficiency, with the help of maxdea software and DEA model, this article measures and decomposes the input-output efficiency of China’s municipal infrastructure from 2006 to 2016, and analyzes its spatial correlation pattern by ESDA method. The results show that: 1) The overall input-output efficiency of China’s urban infrastructure is not high, but it shows a growth trend, and the high-efficiency cities are also increasing at an average speed, gradually changing to scale investment, and the technical efficiency increases slowly. 2) The spatial distribution pattern is high in the eastern China, low in the middle and high in the western China. 3) The spatial agglomeration range of urban infrastructure investment efficiency has shifted, and the hot spot distribution is roughly consistent with its spatial distribution.
