Coupling and Coordination between Medical security Services and Regional Economic Development in Beijing, Tianjin and Hebei：A Comparative Analysis for 2020 and 2022

Objective: To assess the coupling coordination interaction between medical security service capacity and regional economic development level in the Beijing-Tianjin-Hebei region, and provide recommendations for medical reform and residents’ well-being improvement. Methods: The output was obtained by using comprehensive evaluation, coupling coordination, and relative development degree models to analyze the data collated from 2020 and 2022 statistical yearbooks. Results: Significant regional disparities in coupling coordination status were evidenced in 2020 and 2022, with Beijing in the Intermediate coordination stage (D=0.754), while Tianjin (D=0.574) and Hebei (D=0.564) in dyscoordination. Beijing exhibited lagging type of medical security service capacity (A41), while Tianjin demonstrated coordinated development type between regional economic (A32). And Hebei was a lagging type of regional economic development (A33). In 2022, Beijing's relative development degree increased to 0.781, whereas Tianjin's decreased to 0.849. Development types remained unchanged for Beijing, Tianjin and Hebei. Conclusion: Regional disparities exist in medical security service capacity among Beijing, Tianjin and Hebei in 2020 and 2022, revealing a differentiated development pattern. Future strategies should prioritize the improvement actions: (1) innovating regional coordination mechanisms; (2) optimizing medical resources in Beijing; (3) focusing on elderly medical insurance in Tianjin; and (4) strengthening positive feedback mechanisms in Hebei to foster coordinated development.
