The impact of smart city pilot policies on household consumption in households with older adults: mechanisms, heterogeneity, and inequality.
Article in BMC geriatrics, 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
backgroundWith the rapid advancement of Smart City development, its impact on per capita household consumption in households with older adults remains insufficiently understood. This study aims to examine the causal effects of Smart City pilot policies on household consumption and consumption structure among older households in China.
methodsThis study uses panel data from the China Health and Retirement Longitudinal Study from 2011 to 2020. A difference-in-differences approach is employed to identify the causal impact of Smart City pilot policies on per capita household consumption. Mechanism analysis is conducted to explore potential pathways, and heterogeneity analysis is performed across age, education, and income groups.
resultsThe findings show that Smart City policies significantly increase per capita household consumption in households with older adults. This effect is primarily driven by improvements in digital connectivity, healthcare accessibility, and financial inclusion. The positive impact is more pronounced among households with older, less educated, and low- to middle-income members, while no statistically significant effects are observed among younger, higher-educated, or higher-income groups. In terms of consumption structure, Smart City development significantly increases subsistence-oriented expenditure but has limited effects on development- and leisure-oriented consumption. Additionally, the results suggest that these policies contribute to reducing disparities in household consumption.
conclusionsSmart City development plays a significant role in promoting household consumption and reducing consumption inequality among older households. The findings provide micro-level evidence on the distributional effects of urban digital policies and offer important implications for designing inclusive and equitable Smart City strategies.
