A sound regional cold chain logistics network is crucial to promote the development of cold chain logistics of agricultural products, which is conducive to reducing the loss rate and circulation cost of agricultural products in the circulation process and improving the market competitiveness of agricultural products. Based on 2020 in Shandong province each locally administrated level economic level, industry level of development, according to the relative statistic data of the cold chain logistics demand and infrastructure, through principal component analysis to determine the level of cold chain logistics comprehensive ability, and according to the shaft radial gravity model and logistics membership model calculation convergence point between the city and the axis of the city logistics gravity and membership degree, Thus, a hub-and-spoke cold chain logistics network with Qingdao, Weifang, Jinan and Linyi as the four axis cities has been constructed. Finally, in view of the existing problems of the four logistics circles, the paper puts forward some suggestions on the optimization of cold chain logistics system and regional logistics development in Shandong Province.
