Abstract: High quality development is the only way to realize industrial transformation and upgrading, and enhance competitiveness. Giving full play to the role of Internet is an effective way to promote the high-quality development of local industries. Based on the theoretical transmission mechanism of "Internet plus" on the upgrading of industrial clusters, introducing three intermediary variables: human capital, export trade and technological innovation, using the "mediating effect" test method, this paper makes an empirical test on the data from 2011 to 2020, and finds out the influence channel and degree of "Internet plus" on the upgrading of Huailin fishing net industrial cluster in Chaohu City. The results show that the three variables do have significant mediating effects in the order of export trade effect, human capital effect, technological innovation effect, which further verifies that Huailin fishing net industry belongs to labor-intensive industry, and is a buyer driven industrial cluster. In order to promote the transfor mation and upgrading of Huailin fishing net industry cluster, we should make full use of the Internet to promote the accumulation of human capital and technological innovation, and lead the cluster high-quality development through technological innovation.
