山东省城市可持续发展效率时空差异分析
Analysis on Temporal and Spatial Differences of Urban Sustainable Development Efficiency in Shandong Province

为了在有限的资源条件内充分提高区域可持续发展效率，提高城市的可持续发展能力和综合承载能力。本文以2009~2019年山东省16地市的面板数据为基础，从生态、资源、产业、投资等多个方面对山东省城市发展状况进行分析，使用DPSIR模型将诸多因素归结为驱动力、压力、状态、影响、响应五个维度，用熵值法进行数据标准化和权重计算，以此来建立可持续发展效率评价体系，利用SBM模型进行效率计算，基于量化结果和ArcGIS软件对山东省可持续发展效率进行时空差异分析和可视化分析。结果显示：① 从时间序列上看，大部分城市可持续发展效率值波动不大并且处于较低水平，整体表现出上升趋势。② 从空间演化上来看，山东省可持续发展效率存在显著的地域性差异，呈现出“四周高，中间低”的空间分布格局。
In order to fully improve the efficiency of regional sustainable development and improve the sustainable development capacity and comprehensive carrying capacity of the city within the limited resource conditions, based on the panel data of 16 cities in Shandong Province from 2009 to 2019, this paper analyzes the urban development status of Shandong Province from the aspects of ecology, resources, industry and investment. Using DPSIR model, many factors are summarized into five dimensions: driving force, pressure, state, impact and response. The entropy method is used for data standardization and weight calculation. In this way, the sustainable development efficiency evaluation system is established, the efficiency is calculated by SBM model, and the spatial-temporal difference analysis and visual analysis of sustainable development efficiency in Shandong Province are carried out based on the quantitative results and ArcGIS software. The results show that: ① From the time series, the sustainable development efficiency of most cities fluctuates little and is at a low level, showing an upward trend as a whole. ② From the perspective of spatial evolution, there are significant regional differences in the efficiency of sustainable development in Shandong Province, showing a spatial distribution pattern of “high around and low in the middle”.
