Impact of technological heterogeneity on economic efficiency and total factor productivity change in developed and developing G20 economies.
Article in Journal of advanced research, 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
introductionThe G20 economies, comprising both developed and developing nations, exhibit significant economic efficiency and technological advancement disparities. Understanding these differences is critical for fostering sustainable growth, particularly optimizing resource utilization and narrowing technological gaps.
objectivesThis study evaluates economic efficiency, technological heterogeneity, and total factor productivity change (TFPC) among G20 economies from 1997 to 2022. It distinguishes between developed and developing nations to identify key challenges and opportunities for productivity enhancement.
methodsWe assess economic efficiency using Data Envelopment Analysis (DEA) with the Super-SBM model. Meta-Frontier Analysis measures technological disparities, while the Malmquist-Luenberger Productivity Index (MLI) decomposes TFPC into efficiency change (EC) and technological change (TC).
resultsThe mean Meta-frontier efficiency score for G20 countries is 0.9556, indicating a 4.44% improvement potential. Developed economies (e.g., the U.S., Australia) exhibit optimal efficiency, whereas developing nations (e.g., Russia, China, India) lag due to slower technological integration. The Meta-Technology Ratio (MTR) reveals pronounced disparities, with developed economies scoring near 1, while emerging economies range between 0.8 and 0.9. Efficiency change (EC) drives productivity growth more substantially than technological change (TC).
conclusionNarrowing technological gaps, improving resource efficiency, and fostering innovation are vital for sustained economic development, particularly in emerging G20 economies. Policy recommendations include prioritizing R&D investments, technological advancement, and international collaboration to promote equitable and sustainable growth.
