Business Model Innovation Mediates Effect of the Relationship between Digital Technology Application and Supply Chain Concentration in China

Digital technology has demonstrated significant potential in driving economic development. However, international economic competition is becoming increasingly intense, the global situation is tense, and the economic environment is becoming more severe. As a result, the overall security and stability of the upstream and downstream supply chains have suffered significant damage. In this environment, firms are also actively looking for and exploring ways to alleviate the crisis, and digital technology shows outstanding ability in alleviating the supply chain crisis. We obtained the data from the annual reports of Chinese A-share listed manufacturing companies from 2019 to 2024 by using "Python" software, conducted multiple regression analysis using Stata software, and used literature analysis and empirical analysis to explore the impact of digital technology application on the concentration of supply chain of firms, as well as the mediating role of business model innovation in the process. and the mediating role of business model innovation. It is found that the application of digital technology can significantly reduce the supply chain concentration, and the application of digital technology gives rise to business model innovation based on digital technology, which makes the information asymmetry between firms and the upstream and downstream of the supply chain decrease and the communication and transaction efficiency increase, to reduce their supply chain concentration. The significance of the study is that it enriches the research on the path of the application of digital technology affecting the supply chain concentration of firms.
