Abstract:The independent joint venture brand is the inevitable outcome of the development of Chinese auto industry. Its development model has influenced by the political, economic, market environment, the enterprise internal factors. In this paper, for the first time by using the structural equation model, and studying the China GDP, passenger car sales, car owners’ number per thousand people, Engel coefficient and other factors have influence the entry time of the independent joint venture brand, then makes an empirical study on it. Through the model implementation and evaluation with AMOS statistical software, it studies the key factors of the independent joint venture brand ‘s development by researching the factor e which means the entry time of the independent joint venture brand model. And by improving the actual meaning of evaluation index and the variables, the model is modified and improved. The model has been verified in BRICs such as India and Russia which will be brought into play in developing countries and developed countries with large market potential to develop their own independent joint venture brands of automobile. It offers reference in research methods of entry mode and time. The theory model that is quantified has proved its maneuverability and duplicability.
