Based on panel data from 2010 to 2022 for cities, this study uses a double difference method to empirically test the impact of cross-border e-commerce comprehensive pilot zones on the modernization level of industrial chains and their mechanisms. The research findings show that the establishment of cross-border e-commerce comprehensive pilot zones has a significant positive impact on the modernization level of industrial chains, and the reliability of the results remains after passing the placebo test, exclusion of other policy interference, and exclusion of special samples. The heterogeneity test shows that the impact of the establishment of comprehensive pilot zones on the modernization level of industrial chains is more significant in eastern regions, cities with high digital economic development levels, high marketization levels, and high shares of the tertiary industry. The mechanism test shows that comprehensive pilot zones can promote the modernization level of industrial chains through the channels of industrial digitalization, improving science and technology infrastructure, and promoting foreign investment. This study provides empirical evidence and policy reference for improving comprehensive pilot zone policies, accelerating the construction of modern industrial systems, and cultivating new productive forces.展开更多
