With the development of cross-border e-commerce, enterprises often face institutional pressure from external sources when promoting cross-channel integration. 298 data through Smartpls software was analyzed to explore the mechanism of institutional pressures on cross-channel integration, and verify the moderating role of organizational learning in it. It is found that normative, coercive and imitative pressures all positively affect cross-channel integration in firms. Organizational learning moderates the positive relationship between coercive and imitative pressures and cross-channel integration, while the moderating effect of normative pressure is not significant. The article reveals the complex interaction between institutional pressure and cross-channel integration, emphasizes the key moderating role of organizational learning in this process, and provides a theoretical basis for cross-border e-commerce firms to cope with institutional pressure and optimize cross-channel integration strategies.
