### Logistics Sharing Mode
The organizational mechanism is the prerequisite. The cooperation mechanism is the power source. The sharing mechanism is the necessary support information. The collaborative decision-making mechanism is the basic guarantee. The design of the system was more comprehensive, but the construction of a complete system was difficult and not easy to achieve. [PERSON] (2018) built a new joint distribution alliance model of electrical business logistics ends and put forward the concrete implementation strategy. That is, [PERSON] did so by joint investment and receipt, establishing a shared information platform, improving the express formula, making a cost allocation mechanism, forming a reasonable cooperation organization mode to achieve effective operation of the model involving a storage center, making a joint distribution center, and coordinating a distribution network. [PERSON] (2018) and [PERSON] (2018, 2019) studied the joint distribution method of America and Japan. [PERSON] (2019) analyzed the categories of joint distribution patterns, such as one-to-many and many-to-many. One-to-many mode is an orderly delivery activity conducted by a distribution enterprise for multiple customers according to the distribution needs and routes, and the targeted users (users involved in the \"last kilometer problem\" such as individual users and users with high frequency, large quantities, and various categories such as supermarkets and drugstores). Many-to-many mode refers to the cooperation of multiple enterprises, overall arrangement of distribution, and joint service for multiple customers. This mode is mainly used in the joint distribution and transportation of long distance bulk goods by sea, air, and railway. The many-to-many model saves resources and costs because it can increase load rates and reduce redundant transportation by sharing space. By comparing and analyzing the shared logistics model proposed by scholars, at present we summarize four shared logistics modes: cloud warehouse resource sharing mode, logistics equipment sharing mode, logistics crowdsourcing sharing model and the joint distribution and shared logistics model. Among them, logistics equipment sharing mode is limited to the sharing of things such as warehousing and freight equipment, with limited economic benefits and failure to form large-scale and systematic sharing, which limits the possibility of continuous evolution and innovation of this mode. Logistics crowd-sourcing mode focuses on the sharing of personnel in the distribution field, and is not closely related to the cooperation mode and profit among enterprises. Thus it is not considered in this paper. By combining the characteristics of the express industry--scattered and irregular demand for express delivery and the demand for door-to-door delivery--this paper hopes to draw lessons from the cloud warehouse resource sharing mode and the shared distribution logistics mode of joint distribution in order to construct the shared distribution mode of the unified warehouse and distribution in the express industry. That is, to realize the \"sharing\" of storage and distribution. The operation process of the cloud warehouse is shown in Figure 1:  
The core idea of cloud warehouse mode lies in the realization of a unified warehouse through sharing. That is, the effect of combining various scattered warehouses in the same logistics field to form a \"warehouse network.\" In other words, express enterprises ally to integrate their existing warehouses through cooperation. Each warehouse is a node in the warehouse network with exchanges and sharing. The key to the joint distribution model lies in the means of \"sharing,\" that is, the sharing of personnel, information, and resources. Such sharing in many aspects can make full use of the member enterprises' existing resources in the alliance to reduce costs and idle resources.
