Assessing Agricultural Ecological Efficiency in Shandong Province:An Application of the Three-Stage Super-SBM Model
Rural revitalization stands as a critical strategic initiative in the progression towards a modernized socialist country,with sustainable agricultural development being a pivotal element for its success.The impartial assessment of agricultural ecological efficiency yields numerous advantages,such as enriching the quality of rural life and fortifying national food security,while simultaneously underpinning decision-making for ecologically-centered agricultural reform that propels agricultural modernization.This analysis,anchored in panel data from 16 cities within Shandong province during 2012-2021,adopts the three-stage Super-SBM model to quantify agricultural ecological efficiency and employs the Dagum Gini coefficient and the GML index to dissect the spatial-temporal variances and their evolutionary trends.The findings showcase a progressive increase in agricultural ecological efficiency across Shandong Province,with the overall discrepancy displaying a"rise and then fall"trajectory.Regionally,the disparities delineate a descending order:Southwest Shandong＞Eastern Shandong＞Central Shandong＞Northwest Shandong,with a tendency toward regional convergence over time.Notably,the GML index articulates a"rise before a fall"pattern,with technological advancement dictating the index's fluctuations up until 2018.Subsequently,the influence of technological efficiency on agricultural ecological efficiency has become increasingly evident.The advancements in the Eastern Shandong and Southwest Shandong regions can be attributed to the combined effect of optimizing technological efficiency and fostering technological innovation,while the Northwest Shandong and Central Shandong regions still grapple with optimizing technological efficiency.The insights from this research offer strategic guidance for assessing and enhancing agricultural ecological efficiency and for facilitating a green transformation within Shandong province,serving as a benchmark for other regions targeting sustainable agricultural progress.
