Spatial differentiation of productive services and its influencing factors: A case study of Kunming, China.
Article in PloS one, 2025. 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
The transition to a service-based economy represents a key global macroeconomic trend, with productive services playing a critical role in driving economic growth. For China, the development of productive services is a strategic priority in its pursuit of high-quality development. Most existing research primarily relies on traditional data to examine the spatial agglomeration and influencing factors of productive services in economically advanced regions, often overlooking the integration of multi-source data and spatial analyses in less developed areas. This study focuses on Kunming as the case study, employing methods such as Standard Deviation Ellipses (SDE), Kernel Density Estimation (KDE), and Local Spatial Autocorrelation (Moran's I) to investigate its spatial differentiation and agglomeration patterns. Additionally, Geodetector is applied to analyze influencing factors, utilizing multi-source data including Point of Interest(POI), LandScan, the annual China Land Cover Dataset (CLCD), OpenStreetMap (OSM), and socio-economic data to examine the evolutionary patterns of productive services. The findings suggest that Kunming's productive service sectors currently exhibit a predominant southward diffusion, influenced primarily by transportation infrastructure and economic conditions. Moreover, different categories of productive services exhibit unique spatial differentiation and influencing factors. Moving forward, it is essential to prioritize upgrading the internal structure of productive services to foster sustainable and high-quality sectoral development.
