山东半岛城市群人口?土地城镇化质量测度与协调发展研究

统筹人口城镇化与土地城镇化的关系，推动二者之间的稳步协调发展，是提高城镇化发展质量的重要保障，也是实现经济高质量发展的必然选择。以山东半岛城市群为例，在构建人口城镇化和土地城镇化质量评价指标体系的基础上，采用均方差权值法对2000年和2018年8个设区城市人口?土地城镇化质量及其时空演化特征进行测度和分析，利用弹性系数及耦合协调度模型对人口城镇化与土地城镇化发展的协调关系进行深入探讨。结果表明：① 2000年山东半岛城市群人口城镇化和土地城镇化质量不高，各子系统之间差别明显。2000年以后提升迅速，2018年人口城镇化质量总体高于土地城镇化。② 2000—2018年，济南和潍坊的人地弹性系数接近于1，表明18 a间2个城市的人口城镇化与土地城镇化质量提升速度相当，人地关系比较协调；烟台和淄博的弹性系数小于0.6，说明人口城镇化质量的提升速度滞后于土地城镇化；东营、威海、青岛、日照的人地质量弹性系数大于1，反映出18 a间土地城镇化质量提升速度滞后于人口城镇化。③ 无论是2000年还是2018年，山东半岛城市群人口?土地城镇化质量的耦合度都很高，但协调度较低，且时空差异非常明显。2000年多数城市人口–土地城镇化质量的耦合协调类型属于失调型。2018年所有城市均已发展为协调型。

Study on the Quality Measurement and Coordinated Development of Population-land Urbanization in Shandong Peninsula Urban Agglomeration

It is an important guarantee to improve the urbanization quality and an inevitable choice to promote the steady and coordinated development between population urbanization and land urbanization. Taking Shandong Peninsula Urban Agglomeration as an example, based on the construction of population urbanization and land urbanization quality evaluation index system, this article measures the population and land urbanization quality and its spatiotemporal evolution characteristics of 8 cities in 2000 and 2018 by using the mean square error weight method. Using the elastic coefficient and coupling coordination degree model, this article discusses the coordination relationship between population urbanization and land urbanization. The results show that: 1) The quality of population urbanization and land urbanization is not high in Shandong Peninsula Urban Agglomeration in 2000, and the differences among subsystems are obvious. The quality of population urbanization is higher than that of land urbanization in 2018. 2) From 2000 to 2018, the elasticity coefficient of Jinan and Weifang is close to 1, which indicates that the population urbanization and land urbanization quality improvement speed of the two cities are equivalent, and the relationship between human and land is relatively harmonious. The elastic coefficient of Yantai and Zibo is less than 0.6, which indicates that the improvement speed of population urbanization quality lags behind land urbanization quality. The elasticity coefficient of human land quality of Dongying, Weihai, Qingdao and Rizhao is greater than 1, which reflects that the improvement speed of land urbanization quality in these cities has lagged behind that of population urbanization in 18 years. 3) Whether in 2000 or 2018, the coupling degree of population-land urbanization quality of Shandong Peninsula Urban Agglomeration is very high, but the coordination degree is low, and the space-time difference is very obvious. In 2000, the coupling coordination type of population-land urbanization quality in most cities belongs to maladjustment type. In 2018, all cities have developed into coordinated type.
