Research on coupling coordination measurement and driving factors of digital new productivity and high-quality development of logistics industry in Beijing-Tianjin-Hebei region

In the context of the digital economy, digital new-quality productivity is reshaping the high-quality development of the logistics industry, while logistics provides key application scenarios and endogenous momentum for its cultivation. This study explores the coupling coordination mechanism and evolutionary characteristics between the two systems in the BeijingTianjinHebei region. Using regional data from 2016 to 2023, a comprehensive evaluation system is constructed, and a coupling coordination model combined with grey relational analysis is applied to examine inter-system relationships and driving factors. The results show that both digital new-quality productivity and logistics quality exhibit steady upward trends. The coupling coordination degree evolves from a fluctuating adjustment stage to recovery and then toward stable optimization, with clear regional heterogeneity. Technological innovation and infrastructure development are identified as core drivers, while urbanization, openness, and government support play important supporting roles. This study not only empirically clarifies the synergistic evolution mechanism between digital new-quality productivity and high-quality logistics development, but also provides references for optimizing regional collaborative paths and formulating differentiated policies.
