The analysis reveals significant regional disparities in fiscal revenues across Chinese provinces, with coastal provinces like Guangdong and Jiangsu far outperforming inland provinces such as Tibet and Qinghai, reflecting uneven economic development. Nevertheless, most provinces showed a continuous growth trend from 2004 to 2023, demonstrating China's overall economic progress. However, recent years have seen a general slowdown in growth rates, possibly reflecting the impact of economic transformation and structural adjustments. Notably, some provinces like Guizhou and Tibet have experienced rapid fiscal revenue growth, likely tied to national regional development strategies and support policies. Meanwhile, provinces with diversified economic structures, such as Guangdong and Zhejiang, have shown stronger resilience to economic fluctuations, highlighting the importance of industrial diversity for fiscal stability.
