When the human society comes into the era of the new experience of Web3.0, Tencent company offers a "Wechat feast" for the Chinese people relying on its own strong research and development ability. Wechat is a magic mobile communication tool which can send voice messages, texts, images, videos, expressions and it has various kinds of functions such as social interaction, entertainment, online payment, life service and many other functions, so it is widely used in every aspects of life. In the modern enterprise management, Wechat is a new office communication tool, compared with the traditional office tools, its power is still weak. However, the use potential of Wechat for corporate internal communications still has a larger development space. According to the media richness theory and the social information processing model in the field of organizational communication, the characteristic of task and media, the influence of social environment, the individual differences, the accumulated knowledge and the experience of the past are all important influential factors of media choices. Whether these factors affect the use of Wechat in the corporate will be explored in the research. In this paper, employees of three private enterprises are the research objects. Through the questionnaire survey form and depth interview, we will analyze the usage of Wechat in the corporate internal communications and the influencial reasons for its use. In the207recycling valid questionnaires, by using SPSS Statistics software to do the multiple regression analysis, the relationship between population variable factors, media richness, the complexity of task, situational factors and the daily time of Wechat use will be tested. To some degree, the conclusion justifies the influencial factors of Wechat use. Through the test, situational factors, media richness, and task complexity are important factors affecting Wechat use in the corporate communication. The situational factor is the most influential factor, and the media richness is also important factor. Contrary to the media richness theory, the higher the complexity of the task is, the shoter the time of Wechat use is. Demographic variable has little influence on the use of Wechat in the corporate and different demographic variables do not cause significant time differences. In addition, through the depth interview, we learn that WeChat is not widely used in the corporation internal communications, but frequently used in the flexible tasks and informal chats between members. The study of medium choice in the corporate communication will provide a new horizon which would make the modern corpotate run well, so it has a significant theoretical and practical function. |
