“…Many studies have shown that digital economy contributes to the improvement of GVC position (Ardolino et al, 2018;Oliveira et al, 2021). Its main impact mechanisms are: optimizing the layout of GVC production division of labor through mechanisms, such as reducing resource mismatch, increasing proportion of highly skilled talents, and improving production efficiency (Guan and Guo, 2022); promoting international knowledge and technology spillover, which enhances enterprises' technological innovation capacity and efficiency of achievement transformation, and accelerates the industrial structure layout to the upstream of Frontiers in Environmental Science frontiersin.org GVC (Duraivelu, 2022;Zhang et al, 2022); improving the level of digital service, amplifying the promotion effect of application research investment on GVC's status, and enhancing the positive feedback effect of basic research investment on GVC (Yang and Yi, 2021); due to the development of digital technology, the search cost of credit information has been greatly reduced (Spence, 2021), and the information asymmetry existing in almost all markets has been reduced to the lowest level. In this sense, the combination of data and human capital can create a higher return rate (Spence, 2021), help enterprises to participate in knowledge intensive and other high value-added production activities, and drive the upgrading of GVC status (Szalavetz, 2022).…”
