Shandong Province is one of the important provinces on the eastern coast. The total GDP is ranked third in the whole country. Since 2000, urbanization in Shandong Province has entered a period of rapid development, and the urban system has evolved into a focus. At present, there are relatively few research papers on urban system structure in China, and most of the focus is on urban agglomeration and urban circle research. Therefore, based on the socio-economic data of 17 cities from Shandong province, this paper aims to analyze the evolution of the urban system. From the aspect of economic spatial structure, we adopt principal component analysis (PCA) to obtain comprehensive score of economic scale and urban centrality of each city. It shows that Shandong province has developed from a dual-core urban system to a quad-core urban system. These four cores are Qingdao, Jinan, Weifang and Yantai. However, the gap of economical scale between Qingdao and Jinan is still relatively large. Based on the Economical Gravity Model, we obtain the strength of economic linkage between every two cities. It shows that the economic linkage of central Shandong and coastal areas is more concentrated, while economic linkage of southern Shandong is less concentrated. Overall, the urban system of Shandong Province has no obvious core cities and tends to be multi-core distribution. However, the four regional central cities described above are located in the central part of Shandong Province and the coastal peninsula, while the vast northern and southern parts of Shandong Province do not have a regional central city.
