[Purposes] The aim of this work is to explore the process and path of internal transmission of corporate culture in construction enterprises. [Methods] According to the transmission characteristics of corporate culture in construction enterprises, an internal transmission model of corporate culture based on the infectious disease dynamics model is established and the transmission process of corporate culture in construction enterprises is simulated in order to reveal the internal transmission mechanism of construction enterprise culture. [Findings] The transmission of corporate culture in construction enterprises manifests itself in changes in the number of people who understand different levels of corporate culture. As the transmission proceeds, the number of each group will eventually become stable and reach a dynamic balance; In the early stages of transmission, senior management and management in the enterprise are the subjects of transmission, and in the process of transmission, ordinary employees have a subject-object duality in this process in communication theories; The increase in persuasiveness，conversion rate and turnover rate is positively correlated with the speed and effectiveness of corporate culture in construction enterprises, while the increase in abandonment rate,rejection rate is negatively correlated with them.[Conclusions] The process of internal transmission of corporate culture in construction enterprises goes through three stages: emergence, strengthening, transformation.Ordinary employees are the main force in the transmission of corporate culture, and their enthusiasm for their work directly affects the effectiveness and speed of transmission. Enterprises can set up a number of measures in the areas of awareness and advocacy, institutions and communication, which can enhance the enthusiasm of employees and improve the effectiveness of cultural communication.
