This paper studies the current situation of urbanization quality in Shandong province, summarizes the temporal-spatial evolution of urbanization quality, analyzes the issues during Shandong's urbanization process, and presents references in improving urbanization quality and diminishing regional variance. A three-layered of “1-6-25” evaluation index system has been built on the basis of six dimensions, population, economy, society, eco-environment, urbanization efficiency and urban-rural planning. This paper uses global principal component analysis method and ArcGIS to study, temporally and spatially, the county-level urbanization quality evolution in Shandong's 89 counties from 2008 to 2018. Results show an uneven spatial distribution in urbanization quality evolution, high in east, especially in the Jiaodong peninsula and along the Jiaoji railway, and low in west, with an outstanding spatial clustering in grouping and synchronism. During the past decade, Shandong has reached a remarkable achievement in urbanization quality with a fading E-W polarization and an increasing spatial clustering. This paper presents path to urbanization quality in optimizing urban functions pattern, improving industrial structures and boosting eco-environmental construction.
