With the development of online trading, the transaction time of commodities has been able to reach the realm of "equal to zero or close to zero" as Marx said, online trading has led to a huge revolution in commodity trading, not only shorten the time, accelerate the speed of transactions, but also can greatly reduce the cost of commercial transactions, with the Internet as the platform for the Internet as a platform for online trading has increasingly reflected its strong advantages. In the e-commerce swept the world and is expected to become the mainstream business forms of the new century in the context of e-commerce, e-commerce to promote the modernization of logistics and enhance the logistics technology, logistics and e-commerce is the cornerstone and guarantee. This makes the professional logistics industry quietly formed, and occupies an important position in e-commerce. Due to the late start of China's logistics, low level, imperfect management system, can not keep pace with the development of e-commerce, logistics and distribution has become an important bottleneck restricting the rapid development of China's e-commerce, if there is no efficient, reasonable, smooth logistics system, e-commerce, convenient and low-cost consumer advantages are difficult to get effective play. Distribution mode determines the distribution cost and speed, through the research we learned that the current common distribution mode is mainly post office distribution, self-managed distribution, outsourcing distribution. The first is postal distribution. Sellers are using the post office as one of the distribution methods, because the postal service in our country has a very wide coverage, the use of postal services can be done to every county and city in the country, which is a huge advantage that other logistics methods can not do. Therefore, wherever the postal system can reach the place, regardless of e-commerce enterprises are not interested in its market prospects, will provide mailing services to the region, because the postal delivery fee will be transferred to the consumer, which for the enterprise only gain and no loss. However, the postal industry in China has been struggling with poor service quality, slow response, long lead times and slow processes. The sluggish sending speed makes the advantage of fast and convenient online transactions not to be realized, and hinders a large number of consumers from trusting online transactions. Although the speed of express delivery meets the requirements of consumers, but because of the high cost of sending the price advantage of online transactions is difficult to play also difficult to attract consumers. Therefore, in the future, postal service will become a delivery option outside the scope of e-commerce delivery. Self-supporting distribution can provide higher customer value, the mode by the site's own financing to set up logistics and distribution systems. From the signing of the customer's online order to the final arrival of the goods in the hands of the user using a one-stop service, there is no third party involved. Its general method is to set up warehouse centers and distribution points in the more dense areas of Internet users. The biggest advantage of the self-built logistics system, is to have effective control over the logistics system operation process, which enhances the system for the enterprise to serve the customer's specialization, so the speed of delivery and service are very good. In addition it is conducive to the coordination between the various departments within the enterprise, for obtaining first-hand market information also has a role in helping, at the same time, can effectively prevent the leakage of business secrets. For example, Haier set up an e-commerce company, invested more than 100 million, relying on strong financial strength and the formation of the previous marketing network, the establishment of a set of relatively perfect distribution system, in the completion of the Haier service at the same time can also provide distribution services for other enterprises. But for most of the e-commerce enterprises, enterprises to build their own logistics and distribution system, will be dispersed within the enterprise's financial, human and material resources, affecting the development of the main business, and is not conducive to the cultivation of the enterprise's core business. In addition, if the volume of online transactions is limited, the distribution does not reach the scale effect, there is no economy of scale, the natural distribution costs are higher, the enterprise's profitability is reduced. If the logistics and distribution costs are too high, e-commerce goods lack of competitiveness, the enterprise also lacks competitiveness. Furthermore, the lack of professional logistics and distribution personnel. Many self-built logistics and distribution system of most of the employees are the original surplus staff or unemployed, do not understand the logistics and distribution, to let them adapt to the new working conditions and working environment, they need to be retrained, which is a waste of a lot of resources, but also can not carry out logistics and distribution work smoothly. Therefore, the author believes that the number of sales does not reach a certain size of the e-commerce enterprises, do not choose this option for the time being. Outsourcing distribution. Third-party outsourcing distribution model than other ways can be established more quickly, more specialized services can reduce or even eliminate the enterprise in the logistics and distribution concerns, so that it can focus on operating network goods, but also reduce the cost of enterprise logistics and distribution, the new online retailers have a strong attraction, so the third-party is also the choice of most online transactions. With the increase of this part of the business, the courier company has also mushroomed. The four major international courier giants dhl dunhao international, fedex federal express company, ups united parcel company, the Netherlands post tnt entered the Chinese market one after another, and quickly hoarded the power to develop their respective distribution and transportation network, domestic such as EMS, shunfeng, roundtone, shentong, yunda, etc., are not willing to show their weakness, each to develop their own distribution system, are able to provide a certain level of electronic distribution Service capacity, the accessibility of this mature technology and reliable performance, making the outsourcing of distribution has become a very attractive option, but the level of service, service prices vary. Summarized, the advantages of EMS is the most outlets, the most developed network, the disadvantage is that the worst service, the slowest time, charges are also the most expensive; SF's advantage in the Pearl River Delta and Hong Kong's network is the most developed, the highest level of security, the disadvantage is that in other areas of the network is not particularly much, limited to the first and second-tier cities, the charges are relatively high compared to other private courier companies. SF in the distance between the two places farther away faster, especially in the country's big cities is very advantageous, SF's advantage is fast, but the price is more expensive, if you send out express this morning, the country's capital cities basically guarantee that the next day to the morning, SF also has a little bit of a good thing is to send the piece, this afternoon to the piece is generally sent in the afternoon, for insurance purposes, you check the express to the local online! For insurance purposes, you check online to the express to the local area, you can ask him to send immediately; Shentong cheaper, more extensive coverage, the country's major cities are covered, especially in Jiangsu, Zhejiang and Shanghai, and faster, are a day to the advantage of SF in the Yangtze River Delta region network is particularly developed in the rest of the country's network is second only to the EMS, the security of second only to the SF, but the charge is lower than the SF (refers to the long-term contract customers). As for other courier companies, due to the network are only limited to a relatively small range of specific areas, often need to deliver their own network can not be delivered to the express delivery company specializing in other courier companies, often resulting in the loss of pieces, and the time can not be guaranteed. So to choose the daily, YunDa, Yuantong, Home Delivery and other companies must be clear about the scope of its developed network distribution, even including FedEx is also the case. However, UPS and Home Delivery can not deliver the pieces will take the initiative to inform the customer and refuse to accept. From this, we put forward the relevant recommendations are: for enterprises, it is necessary to carefully analyze the advantages and disadvantages of various distribution models, and their own situation, to choose the optimal distribution model.
