This paper takes JD Health as the research subject and employs a modified Customer Value Based on Customer Behavior (CVBC) model to conduct an in-depth discussion and empirical analysis on the value assessment of Internet e-commerce enterprises. By introducing key parameters such as user quantity forecasting, calculation of user marginal value, new user cost, and determination of the discount rate, this paper constructs a more scientific and rational assessment framework. Empirical analysis shows that the modified CVBC model can accurately assess the market value of JD Health, with a smaller error rate compared to the actual market value, verifying the effectiveness and applicability of the model. The significance of this study lies in providing a new perspective that emphasizes the central role of user size, user marginal value, and user cost in the value assessment of Internet companies. The application of this model helps investors and decision-makers to more accurately assess and understand the true value of Internet companies, promoting market efficiency and rational allocation of resources.展开更多

Just in these backgrounds,...Most of the Internet or e-commerce corporations have few earnings or even none. The traditional corporation valuation methods don not work well when encountering these types of corporations. Just in these backgrounds, a new method called CVBC model is brought forward to evaluate these types of corporations in our article, which is based on the customer lifetime value. In essence, it extends the concept of customer lifetime value and combined with the traditional financial methods, then creates a new valuation method. It can work well to the corporations, which have been said before. The principle, mathematical model of the method and the effect of the practical application are discussed in detail.展开更多
