英文摘要：

E-commerce industry in China has developed rapidly in recent years. Due to intensive competition,E-commerce is a low profi- table industry, thus companies have been exhausted with price wars to snatch customer resources. More and more E-commerce companies Start to place emphasis on superior service, such as extending product categories,launching customization and personalization and etc. It is noticed that E-commerce companies in China have switched their value proposition from providing efficiency to a more complicated fash- ion. Here we provide an evolutionary perspective of value proposition, which is the core of the concept of business model, and other related constructs of interest. Based on a longitudinal study by analyzing 838 pieces of news between 2003 and 2012 on the industry, this explorato- ry study shows an explicit and reasonable changing trend of value proposition and also presents the underlying logic of the co-evolutionary change between the constructs composing business model.
