Can urban‒rural health insurance integration narrow the urban‒rural income gap? Evidence from China.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe excessive urban‒rural income gap has been one of the main challenges facing developing countries. The establishment and improvement of health insurance is conducive to narrowing the income gap.
methodsOn the basis of the quasinatural experiment of urban–rural health insurance integration in China, we investigate the impact and mechanism of action of health insurance integration on the urban–rural income gap using the staggered difference–in-differences (DID) model.
resultsThe research findings empirically indicate that health insurance integration has narrowed the urban–rural income gap by a large margin (average treatment effect on the treated (ATT)=-0.013, p < 0.01). The heterogeneity analysis reveal that in the central and western regions and in cities with large urban‒rural income gaps and high fiscal expenditure ratios, the policy effect of health insurance integration is more pronounced. Further research into the income effects of health insurance integration reveals that health insurance integration can increase the income growth of rural residents but has no significant influence on that of urban residents. We also observe through mechanism analysis that health insurance integration can narrow the urban‒rural income gap by improving rural residents’ health.
conclusionsThis study indicates that health insurance integration is an effective means of narrowing the urban‒rural income gap. The research findings of this paper provide empirical evidence for how to optimize the income distribution pattern through the reform of health insurance.
