To gain a competitive edge in the market， Chinese firms need to break the low-end lock-in， achieve high-level leadership， and shape the corresponding leading organizational identity. However， the emotion-centric philosophy inherent in Chinese traditional culture amplifies the impact and shaping power of individual emotions on organizational identity. Yet， it remains unclear how the personal emotions of the core identity stakeholders， including internal members and external customers， actually drive the formation of leading organizational identity. Specifically， how do the individual emotions of the organizational identity audience drive the construction process？ This question still lacks a clear theoretical answer. Therefore， it conducted a multi-case study on Siji Group， TsingShan and Feihe as the samples. The research finds that the process of emotion promoting the construction of the leading organizational identity is the process of emotion promoting the construction of the three-layer structure of it in different ways， namely， the leading idea layer， the superior connotation layer and the advantageous identification layer. Specifically， in the first stage， it builds the leading idea layer through the power of positive emotions. Emotional promotion focuses on stimulating positive emotions， seeking emotional sustentation and building emotional bridges through the temporal structure to exert the lever effect of emotions. In the second stage， it builds the layer of superior connotations through the power of emotional resonance. Emotional promotion focuses on encapsulation of emotional resonance. It plays the supporting role of emotion by promoting the temporal transfer of emotion and enhancing the individual-organizational identity association. In the third stage ，it builds the layer of advantageous perception through the power of emotional motivation，takes the formation of emotional commitment as the core， and plays the driving role of emotion by carrying out vertical contagion and horizontal interaction of emotion and deepening the identification of audiences. By revealing the process and mechanism of how emotion driving leading organizational identity construction， it contributes to the corresponding theoretical research and tries to guide the practice of Chinese firms.
