Basic characteristics of e-commerce: From the meaning and development of e-commerce, we can see that e-commerce has the following basic characteristics: 1. As a new transaction mode, e-commerce has brought manufacturers, circulation enterprises, consumers and the government into a new world of network economy and digital existence. 2. Convenience In the e-commerce environment, people are no longer limited by geography, and customers can complete complicated business activities in the past in a very simple way. For example, online banking can access account funds and query information all day, and at the same time, it can greatly improve the service quality of enterprises to customers. In the business activities of e-commerce, there are a large number of contacts who need to develop and communicate, with flexible working hours, fulfilling the requirements of the company, and having money and leisure. 3. Holistic e-commerce can standardize the workflow of transaction processing and integrate manual operation and electronic information processing into an inseparable whole, which can not only improve the utilization rate of manpower and material resources, but also improve the rigor of system operation. 4. Security In e-commerce, security is a crucial core issue, which requires the network to provide an end-to-end security solution, such as encryption mechanism, signature mechanism, security management, access control, firewall and anti-virus protection. This is very different from traditional business activities. 5. Coordinated commercial activities are a coordinated process, which requires the coordination between customers and companies, manufacturers, wholesalers and retailers. In the e-commerce environment, banks, distribution centers, communication departments, technical services and other departments need to cooperate, and the whole process of e-commerce is often completed in one go.
