Research Status of Urban Logistics Distribution at Home and Abroad

At present, the international definition of urban logistics distribution system is the process of overall optimization of logistics and transportation activities by companies engaged in logistics distribution services in cities under the framework of market economy. In this process, traffic environment, traffic congestion, energy consumption and other factors should also be considered. As can be seen from the above definition, the goal of urban logistics distribution system has two sides: on the one hand, companies engaged in logistics distribution should try their best to reduce costs, serve customers and increase profits from the perspective of their own interests; On the other hand, it is necessary to reduce traffic congestion from the public interest. In recent years, the EU has enacted relevant laws to strengthen the competition in the freight market within the EU. In order to reduce the cost of enterprises, many individual transport operators, as third-party logistics service providers, have established a unified freight service network among urban agglomerations in a certain area through joint ventures. In this process, a new "hub and spoke" freight network gradually formed. The urban agglomeration logistics distribution system based on hub-and-spoke network mode will greatly improve the speed and operation efficiency of urban agglomeration logistics distribution and alleviate traffic congestion with its characteristics of convenience, punctuality, flexibility, networking and integration. This model has positive reference significance for the logistics distribution system planning of urban agglomerations such as Yangtze River Delta and Pearl River Delta in China.
