Construction of Cold Chain Logistics Network for Agricultural Products in Hefei Metropolitan Area
The logistics network system of Hefei metropolitan area plays an important role in the development of logistics in the Yangtze River Delta region.Reasonably constructing the logistics network in this region can not only promote development of the regional economies,but also facilitate the integrated development of the Yangtze River Delta and narrow the development gap.The study predicts the scale of cold chain logistics demand for agricultural products in the Hefei metropolitan area from 2022 to 2026 by establishing a grey GM(1,1)model,and analyzes the spatial distribution characteristics of logistics demand in 2012,2019,and 2026 by Arcmap 10.8 software.This paper constructs a comprehensive development evaluation index system for agricultural cold chain logistics from four dimensions:regional economy,logistics industry,agricultural product supply,and demand.It obtains the logistics quality of each prefecture-level city through the entropy weight TOPSIS model,and divides the hub and spoke cities based on the logistics quality.Applying the gravity model to calculate the gravity intensity and logistics membership between cities at different levels,combining with the calculation results,is constructed a cold chain logistics network for agricultural products with Hefei City as the hub.
