In order to explore the supply chain concentration influence on digital transformation level among enterprises, the analysis in this paper takes a sample about the Chinese wholesale and retail industry enterprise data from 2010 to 2020. Python is used to obtain the data of enterprises about digital transformation, and studies the impact of supply chain concentration on the digital transformation of trading enterprises. Empirical results show that the higher the concentration of the supply chain, the lower the investment of enterprises in digital transformation. In addition, further exploring the impact of the concentration of upstream and downstream partners in the supply chain on digital transformation, it is concluded that the concentration of downstream customers has a more significant negative correlation. At the conclusion of this paper, this paper makes suggestions on how to effectively achieve digital transformation for enterprises with different degrees of supply chain concentration.
