Abstract: The integration of the automobile manufacturing industry and the internet industry has important practical significance for promoting the transformation and upgrading of automobile industry. By constructing an industrial integration measurement model based on the entropy weight method and the grey relational analysis method, a comprehensive evaluation of the integrated development of the automobile manufacturing industry and the Internet industry was assessed. Taking Jiangxi province as an example, empirical research was carried out on the development level, integration degree, integration coordination degree and integration related influencing factors of the automobile manufacturing industry and the internet industry. The research shows that the integration degree of automobile manufacturing industry and internet industry in Jiangxi province is low from 2017 to 2019.
