Analysis Of Spatial Differences And Influencing Factors Of Shandong Peninsula Urban Agglomeration

In the process of urbanization development in China,the regional spatial polarization phenomenon is ubiquitous,the study of the regional development model can not only realize the efficient utilization of the whole area resources,but also can use a broader perspective to locate each city,and provide the basis for the development strategy of the city.In order to explore the spatial difference of Shandong Peninsula Urban agglomeration and its influencing factors,the research method of quantitative analysis is adopted to study the urban agglomeration of new towns.Using the entropy method to measure the polarization level of regional development,using the mathematical models of ER index,Gini coefficient,TW index and Thiel Index,which are commonly used in regional space polarization,with the aid of spatial autocorrelation,principal component analysis,grey relational method and regression analysis,This paper explores the spatial structure of Shandong Peninsula Urban agglomeration.The results show that the city group of Shandong Peninsula presents four kinds of functions,such as modern service industry,manufacturing industry,traditional service industry and producer service industry,and the other three functions are the features of "Jinan-Qingdao Dual-core" service area,the function of manufacturing industry is the Ding structure of " QZY",the spatial difference of comprehensive index is weaker,the strength of urban Comprehensive Development Index shows the consistent characteristics with administrative grade,and the "point-axis" space structure is obvious from the urban agglomeration scale.The initial appearance of local regional network features,the core edge is still outstanding,the overall change of urban comprehensive development level is not big,the polarization development of the original Central city is very obvious;the factors influencing the spatial difference of urban agglomerations in Shandong Peninsula mainly come from the level of urbanization,investment ability and industrialization.
