To keep pace with the development of the times and ensure a steadfast competitive position, traditional enterprises should pay attention to the development of e-commerce business and achieve enterprise marketing strategies through enough channels. In this paper, through the analysis on the current situation and restriction factors of e-commerce in traditional enterprises, suggestions are provided for traditional enterprises to construct sales model and marketing strategy, hoping a help can be provided for the enterprises to develop e-commerce and enhance the competitiveness in the market.展开更多
