Existing studies lack quantitative evaluation of blockchain technology’s application efficiency in this context and systematic analysis of barrier mechanisms. This paper constructs an analytical framework of “technological characteristics-financing process-efficiency output”, using the DEA-BCC model, Malmquist index, grounded theory, and ISM-ANP model for empirical analysis. The results showed that blockchain significantly empowers cross-border trade finance, with total factor productivity (TFP) increasing by 14% in 2023–2024, mainly driven by technological efficiency improvement. Core enterprises (comprehensive technical efficiency 0.82) outperform SMEs (0.65), showing a “Matthew Effect”. Moreover, barriers form a three-level structure of “underlying root-middle-level transmission-surface manifestations”, with technical (weight 0.32) and institutional barriers (0.28) as core constraints, especially insufficient cross-border regulatory coordination (0.12) and inconsistent cross-chain standards (0.10). Prioritizing these underlying barriers is key to breaking “digital silos”, and the proposed hierarchical governance strategy provides support for GBA financial infrastructure interconnection.
