Channel economy development can promote urban economic development and help achieve industrial upgrading of enterprises located along the channel. According to the top 500 Chinese enterprises during the period of 2015 to 2024, the sample comprises 86 enterprises for the study. Using channel economic development as an independent variable and enterprise brand value as a dependent variable, the difference-in-difference method will be used to assess the impact of channel economic development on brand value and the mechanism behind it. It is found that there is a statistically significant positive relationship between the enterprise brand value and the DID performance at the 1% significance level, and the development of channel economy plays a critical role in increasing brand value, which holds up even after the robustness tests. Moreover, the spatial spillover effect of channel economic development on enterprise brand value demonstrates a trend of initially restraining and later promoting. At the same time, the constraint effect of channel economic development on surrounding enterprises increases with the increase in geographic distance. Also, the impact varies according to the enterprise size, property right nature, location, and industry type. Finally, the enhancement path for product brand value will be proposed by using the CBBE model to increase enterprise brand value.
