Temporal and spatial dynamics of hepatitis incidence in China based on the STWR model
This study explores spatio-temporal dynamics of hepatitis B (HBV) and C (HCV) incidence in China from 2012-2019 using Local Indicators of Spatial Association (LISA) and Mann-Kendall (MK) trend tests, along with a Spatio-Temporal Weighted Regression (STWR) model. Key findings reveal significant provincial heterogeneity in HBV (8 provinces decreased, 4 increased) and HCV (7 decreased, 17 increased) incidence trends. HBV showed "high-high" clustering, while HCV exhibited diverse "high-low," "low-high," and "low-low" patterns. The STWR model outperformed traditional OLS and GWR models, highlighting profound spatio-temporal non-stationarity in the associations of economic development, health expenditures, CDC personnel, healthcare institutions, and population density with hepatitis incidence. The study concludes that effective hepatitis control requires synchronized economic development with public health investment, optimized CDC operations, resource allocation, and dynamic regional intervention strategies.

Spatio-temporal Heterogeneity
The study identifies significant provincial heterogeneity in HBV and HCV incidence trends, demonstrating that control efforts vary substantially across regions. This non-stationarity underscores the need for localized and adaptable intervention strategies rather than a one-size-fits-all approach.
Driving Factors (Economic & Health)
Economic development, government health expenditures, CDC personnel, healthcare institutions, and population density are crucial drivers. The STWR model reveals that their associations with hepatitis incidence are not uniform across space and time, indicating complex interplay.
Model Superiority
The STWR model significantly outperforms traditional OLS and GWR models in capturing both spatial and temporal non-stationarity, providing a more accurate and nuanced understanding of disease dynamics.

Case Study: Impact of Economic & Public Health Efforts in GD Province
Challenge: Initially, GDP growth did not automatically translate to reduced HBV incidence (positive GDP coefficient in 2015), indicating a lag in public health benefits.
Solution: Sustained increase in government health spending combined with targeted public health interventions. This includes optimized CDC operations, healthcare resource allocation, and vigilant management of population mobility risks.
Impact: Consistently negative coefficients for health expenditure and GDP shifting from positive to negative by 2019, confirming that economic advantages, when combined with commensurate public health investment, lead to effective disease control and reduced HBV incidence.
