Evaluation and heterogeneity of the green total factor productivity of Shandong Province, China: a super-SBM and GML analysis.
Article in Scientific reports, 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
As a pioneering zone for the transformation of old and new growth drivers, the characteristics and issues manifested by Shandong Province during the course of industrial structure adjustment and economic transformation can best represent the green transformation and sustainable development of the Chinese economy. On the basis of multidimensional panel data from 2007 to 2020, this study employs the superefficiency slack-based measure (super-SBM) model, which considers undesirable outputs, and the global Malmquist-Luenberger (GML) index to measure the green total factor productivity (GTFP) of 16 cities in Shandong Province and analyzes the dynamic characteristics of GTFP and its growth drivers from three dimensions-overall characteristics, regional differences, and urban scale levels. The results show that (1) the GTFP of Shandong Province exhibited a year-on-year decline before 2011, transformed into slow growth during 2011-2015, and then presented rapid growth after 2015. Overall, GTFP, technical efficiency, and technological progress increased at average annual rates of 0.95%, 0.74%, and 0.21%, respectively. Before 2015, the variation in GTFP relied mainly on technical efficiency, whereas after 2015, technological progress made a greater contribution to GTFP. (2) The Jiaodong Economic Circle experienced the greatest growth in GTFP, followed by the Provincial Capital Economic Circle, whereas the Lunan Economic Circle exhibited an overall downward trend. The enhancement of technical efficiency was the main driving force for the growth of GTFP in each economic circle and the main cause for the formation of the GTFP gap among economic circles. (3) Compared with other cities, regional megacities such as Jinan and Qingdao possess unparalleled advantages in terms of economy, talent, and infrastructure; therefore, the growth rate of GTFP is significantly greater in these megacities than in other cities.
