With the development of modern logistics industry, a new logistics mode - the fourth party logistics emerged quietly. It has been widely concerned by scholars and enterprises for its excellent supply chain management ability and resource integration ability. The fourth party logistics is a logistics provider. Through the whole supply chain, it realizes the sharing of logistics information resources and the full utilization of social resources, thus realizing the maximization of enterprise interests and improving the operating efficiency of the whole social logistics system. So the fourth party logistics is the future development direction of the logistics industry. Therefore, studying the main body and operation mode of fourth-party logistics enterprises plays an important role in improving the level of enterprise supply chain management and promoting the growth of the national economy. If China wants to accelerate the development of supply chain management, it must first promote the formation and development of the logistics industry. It is necessary to vigorously develop third-party logistics and actively promote the healthy development of fourth-party logistics. With the structural adjustment and organizational reorganization of China's large logistics companies, the operating pressure of small and medium-sized logistics companies has increased, which has led to the deterioration of the operating environment and narrowed their footholds in the logistics market.The purpose of this study is to solve the problem of logistics development of small and medium sized enterprises and promote logistics development of small and medium sized enterprises through the comparison and analysis of live-use cases.
