（1） At present, small and medium-sized enterprises in our country generally have the phenomenon of low level of information, which limits the premise and auxiliary environment of ERP implementation and application. In terms of network application, less than half of the small and medium-sized enterprises are connected to the Internet, and the situation in the eastern coastal areas is slightly better. However, these enterprises are far away from ERP application. There are two deep-seated reasons. First, the scale of enterprises is small, and cash flow and logistics are more economical by hand; Second, the professional level of personnel is low, even if the cost of purchasing ERP is high, it still can not play its functions, resulting in capital waste and management difficulties. In addition, some enterprises in the circulation field, such as trade companies and wholesale companies, although widely used in the network and technically meet the technical level of using ERP, still do not think that ERP application is a reasonable choice corresponding to the current enterprise scale, and in the scale of the enterprise, it is uneconomical to choose and apply ERP. In the aspect of LAN construction, there are quite a number of enterprises that have not established internal LAN and database. According to the survey and estimation of relevant scholars, the proportion may reach 42.4%. The informatization level of these enterprises is relatively low, and the application of ERP is restricted at the technical level.
