Spatio-temporal evolution and driving factors of China's foreign aid: a country-level analysis.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Understanding the spatiotemporal patterns and associated drivers of China’s foreign aid is essential for characterizing its structural distribution and temporal evolution. Using project-level and financial data from the AidData database (2000–2021), combined with multi-source indicators from the World Bank WDI and UN Comtrade, this study applies geospatial analysis and machine learning models to quantify the country-level spatiotemporal patterns and potential determinants of China’s foreign aid. A SHAP-based framework is further used to identify the nonlinear contributions of key variables. The results indicate that: (1) the number of projects and total funding increased in several distinct phases, forming a dual-core spatial pattern concentrated in Africa and Asia, with infrastructure and social public services accounting for a large share of sectoral allocations; (2) regional profiles differ substantially—Africa and Asia mainly receive aid related to basic development sectors, the Middle East exhibits no persistent dominant sector, and Europe shows a relatively higher proportion of production- and economy-related projects; (3) spatial clustering is evident, with Sub-Saharan Africa and South Asia maintaining long-term high–high clusters in project counts, whereas funding amounts show higher variability and dispersion; and (4) aid allocation is associated with economic, trade, and political indicators, with recipient development level exhibiting the strongest contribution, while resource-related variables show comparatively weaker explanatory power.
