Research on the Economic Spatial Connection in Coastal and Hinterland of Shandong Province

This paper takes 10 inland cities and 7 coastal cities in Shandong Province as the research object, and uses the Gravity Model to explore the spatial-temporal evolution of economic linkage strength and economic connection intensity between coastal and hinterland of Shandong Province from the perspective of population and gross value of production. Through empirical analysis, it is concluded that the economic spatial connection strength of the coastal and hinterland of Shandong Province is becoming stronger and stronger as a whole, each coastal (inland) city is different from the inland (coastal) cities in economic spatial connection and at the same time, and the economic spatial intensity of the coastal and hinterland of Shandong Province is generally not very high. The reasons are briefly analyzed. Based on this, some suggestions were made.
