At present, chronic non-communicable diseases have become the major diseases affecting people's health in China. Most of the studies on resource allocation for chronic disease prevention and control are status quo surveys or equity analyses, and there is a lack of representative indicators for evaluating the results.

To analyze the changes of the appropriateness of resource allocation for chronic disease prevention and control in Chongqing, and to explore its impact on the effectiveness of chronic disease prevention and control.

In accordance with the principle of " exhaustiveness ", this study systematically collected all the literature in the field of chronic diseases in Chongqing from 2010 to 2021 published on the websites of the government, the Health and Planning Commission and its related departments, as well as on open databases such as the CNKI and the Web of Science, and a quantitative analysis was made on the appropriateness of resource allocation for the prevention and control of chronic diseases. After the systematic collection of information, this study was respectively carried out from the four secondary indicators and thirteen tertiary indicators of the appropriateness of resource allocation for chronic disease prevention and control, which was derived from the quantitative standards previously constructed by the research group. The "five-point scale" method was used to semi-quantitatively score the severity of the problem (0 points indicate that there is no problem, 5 points indicate that the problem is very serious) and the scores were further calculated to determine the appropriateness of resource allocation. Correlation analysis and linear regression were used to analyze the influence of the appropriateness of resource allocation on the prevention and control of chronic diseases.

From 2010 to 2021, the appropriateness of resource allocation for chronic disease prevention and control in Chongqing has increased from 6.64% to 27.57%; the appropriateness of human resource allocation has increased from 36.49% to 46.59%, the appropriateness of financial resource allocation has increased from 41.06% to 50.28%, the appropriateness of material resource allocation has increased from 41.40% to 42.96%, and the appropriateness of information resource allocation has increased from 5.73% to 24.09%. Among them, the appropriateness of financial and material resource allocation is significantly negatively correlated with the premature mortality rate of chronic diseases in Chongqing, with correlation coefficients of -0.722 and -0.586, respectively.

The appropriateness of resources allocation for the prevention and control of chronic diseases in Chongqing has been increasing year by year, but it is still at a lower level in general, and the main reason restricting its development lies in the relatively low information resources allocation; it is important to expedite the enhancement of the appropriateness of resources allocation to cope with the rapid increase of the number of chronic disease cases.
