E-commerce in business activities are very prominent, the following activities, which option does not belong to its features

Constructing China's e-commerce logistics system, there can be the following three modes: First, e-commerce and traditional business **** with a set of logistics systems; Second, by the e-commerce enterprises to set up their own logistics system; Third, e-commerce enterprises will be all the logistics business outsourcing form entrusted to the third-party logistics enterprises to operate. The so-called third party logistics refers to the commission of the supplier or seller, by the supplier and seller outside the third party is responsible for the effective management of the intermediate links in the logistics, to provide from the source of supply to the final sale of goods between the full range of logistics services, which is adapted to the new logistics model of e-commerce - logistics agency, logistics agent ( Third Party Logistics, abbreviated as TPL, that is, the third party to provide logistics services) is defined as: "logistics channels in the specialized logistics intermediary, in order to sign a contract for a certain period of time, for other companies to provide all or some aspects of the logistics business services. Characteristics: In order to meet the needs of developing e-commerce, the logistics system for e-commerce collaboration must have three basic characteristics: ① A rapid response capability. The logistics system must obviously realize "online collaboration" with the website store, on the one hand, timely delivery instructions from the website store, on the other hand, quickly report to the website store inventory situation, in order to quickly organize the source of goods; ② has a wide service area. As customers into e-commerce in the real world in a wide range of distribution - this is also an important way to obtain economies of scale of the site store, therefore, the geographical scope of commodity distribution may be very wide, objectively require the logistics system to be able to distribute goods for those customers who are far away; ③ can undertake multiple service functions. If e-commerce is a website store through the Internet to contact customers, then the logistics system is on behalf of the website store in the real world and customer contact. Many customer services are difficult to complete in the virtual world, the site store should use the logistics system to provide customers with these services, in order to really make the customer satisfied, and can win customers. The services that the logistics system can provide to the customers on behalf of the web store include: measurement of the customer's conditions of use or use of the system design, home delivery, installation and debugging, return or replacement, maintenance, distribution of souvenirs and tickets, and payment of goods in cash. These characteristics indicate that the logistics system working with the web store should be a logistics management system using modern information technology. Only a commodity distribution system that can provide the above services and has the above characteristics can be said to have operational efficiency for the development of e-commerce. These characteristics provide some useful bases for evaluating the operational efficiency of a logistics system. Web stores can solve the logistics problem in two ways: one is to use their own capital to build a merchandise distribution system for e-commerce; the other is to utilize external resources - for example, the merchandise distribution systems of existing retailers and mail-order companies. They are also two options for web stores to build their own merchandise distribution system. Among these two options of merchandise distribution system, the one that web stores should choose is the one with higher operational efficiency. The biggest advantage for the web store to utilize its own logistics system is to have effective control over the operation process of the logistics system, which enhances the system's exclusivity for the web store to serve its customers. Firstly, the web store can control the goods distribution activities through its internal administrative power without having to negotiate the commission of goods distribution, which improves the efficiency of distribution services and reduces the transaction costs; secondly, it can control or avoid competitors' utilization of the goods distribution system, which guarantees the priority of the web store's customer services; thirdly, the goods distribution system can be closely coordinated with the web store's marketing activities, which improves the efficiency of the web store's customer services. Thirdly, the merchandise distribution system can be closely coordinated with the marketing activities of the web shop, so as to improve the market appeal, competitiveness and brand value of the web store; fourthly, the merchandise distribution system can also provide the web store with inventory management, market research and cash payment collection and many other service functions. In addition, some website stores can also take advantage of the self-built logistics system to go from the virtual world into the real world, and operate the logistics organization as an ordinary retail store to realize the "amphibious" development. The main defects of the self-built logistics system are huge investment and management difficulties, and it is difficult to obtain the desired economies of scale. The main difficulty in management is that in the huge commodity distribution system, the upper management is difficult to accurately grasp the actual working situation of the lower staff, thus it is difficult to effectively mobilize the enthusiasm and creativity of the subordinate staff, and it is necessary to increase the investment in management power. In addition, when there are unpredictable fluctuations in the sales of website stores, the utilization efficiency of the capacity resources of the commodity distribution system is uncertain, especially when the sales of the website decrease significantly, the capacity resources will be wasted. Managers must strengthen their market research work and improve their sales forecasting ability, and they must improve the utilization efficiency of the merchandise distribution system by developing multiple businesses and other means. If the management costs of a self-built logistics system are too high for a web store to achieve the desired benefits, it is necessary to consider utilizing an external logistics system and "outsourcing" the goods distribution labor. Utilizing logistics systems other than website stores*** to develop e-commerce, which is growing in popularity and has significant benefits, is based on the principles of clear rights, "bundled" operation, opportunity*** sharing, and risk sharing. Generally speaking, the use of external logistics systems, the implementation of commodity distribution "outsourcing", the biggest advantage is that you can make more use of social resources, expanding the scope of spatial distribution of the site service customers, for the site store to bring greater benefits of the scale of sales, to reduce the site store on the investment in the logistics system, conducive to the development of specialized operations, reduce the site store It is also conducive to the development of specialized management and reduces the cost consumption of managing the logistics system. However, it is not easy to establish and maintain a good cooperative relationship between a web store and an external logistics system, unless the web store has special market influence and sufficient business volume to bring attraction. These factors are capable of reducing the economic efficiency of utilizing an external logistics system. Whether to choose the option of a self-built logistics system or the option of "outsourcing" the distribution of goods, it is necessary to take into account not only the conditions of the enterprise itself, but also to analyze the characteristics of the goods handled, as well as the distribution of customers and the strategic needs of the company's development. The key is to carry out scientific and accurate measurement and evaluation of the economic efficiency of the relevant programs, and choose economically rational programs.
