[Main characteristics and historical evolution of China' s health financing transition].

Objective: To comprehend the main characteristics and historical evolution of health financing transition in China.

Methods: Data were collected from various sources, including the Global Health Expenditure Database (GHED), China Health Statistics Yearbook, National Health Finance Annual Report, China ' s Total Health Expenditure Research Report, et al. Descriptive statistics and literature study was conducted.

Results: Since the beginning of the 21st century, most countries in the world had witnessed a transition of health financing, characterized by the expansion of health financing scale and the strengthening of public financing responsibility. Notably, China ' s health financing transition exhibited distinctive features. Firstly, there had been a more rapid expansion in health financing scale compared with global averages. Between 2000 and 2019, total health expenditure per capita experienced a remarkable increase of 816.6% at comparable prices, significantly surpassing average growth rates observed among other countries worldwide (102.1%). Secondly, greater efforts had been made to strengthen the responsibilities of public financing. From 2000 to 2019, there was a substantial decrease of 30.6 percentage points in the proportion of out-of-pocket health expenditure as a share of total health expenditure. This decline was significantly larger than the average reduction observed among other countries worldwide (5.6 percentage points). Thirdly, there had been a significant shift in government health expenditure allocation patterns, with an increased emphasis on "demand-side subsidies" surpassing "supply-side subsidies". Within the realm of "supply-side subsidies", funding directed towards hospitals had notably increased and surpassed that allocated to primary healthcare institutions and public health institutions. Based on these distinctive characteristics, this paper expanded China ' s health financing transition into three dimensions: Scale dimension, structure dimension and flow dimension. Using a comprehensive analytical framework, the history of China ' s health financing transition was roughly divided into four stages: The planned economy stage, the economic transition stage, the post-SARS stage and the new health system reform stage. The main features and evolutionary logic associated with each stage were analyzed.

Conclusion: Above all, the health financing system should be enhanced in terms of vertical "embeddedness" and horizontal "complementarity". Moreover, the significance of health financing transition in preserving hidden value and mitigating public risk should be emphasized, and there is a need for an improved two-way trade-off mechanism that balances value and risk. Additionally, the ethical principles associated with health financing transition should be considered comprehensively, while optimizing budget decision-making within the government ' s actual governance model. Lastly, it is crucial to recognize the overall and profound impact of modern medicine development and explore long-term strategies and pathways for health financing transition in China.
