In the present qualitative and linear analysis of the growth factors by the user growth model,the linkage relationship between links and the priority of link optimization is not explained.This paper disassembled the composition of product user scale in a quantitative way for the first time,used the method of loop iteration to deduce the variables to the beginning stage of growth,obtained the quantitative relationship between user scale and each variable,and solved the linkage and priority problem of elaborating growth factors.What is different from the existing model ideas is that this paper believed that the user growth was not linear,but was based on the accumulative product experience,and cooperated with recall and customer acquisition strategies in each period to achieve the maximial result.The English initials of each link formed E-CAM models.Based on the E-CAM model,the revised and new team assessment indicators were proposed from the perspective of growth team formation;from the perspective of growth strategy,it was proposed to obtain the best customer acquisition in each phase through the principle of op-erations research under the constraint of customer acquisition cost in order to maximize the number of users.
