Agricultural production efficiency estimation and spatiotemporal convergence characteristic analysis in the Yangtze River Economic Belt: A semi‐parametric metafrontier approach

Abstract

AbstractThe sustainable development goals regard improving agricultural production efficiency (APE) as the main method to solve food security problems. Based on the geographical cognition, combined with the functional positioning, we used meta semi‐parametric linear programming and spatial convergence models to analyze the spatiotemporal convergence characteristics of APE in the Yangtze River Economic Belt from 2000 to 2020. The results show that (1) under the framework of metafrontier analysis, the APE increases while maintaining an olive‐shaped stable structure of “sharp at both ends and wide in the middle”; (2) the efficiencies in agricultural production areas and the middle reaches has obviously declined compared with that of non‐agricultural production areas; and (3) non‐spatial factors and spatial factors jointly drive the convergence. The research results can provide references for clarifying the evolution law of regional agriculture and formulating differentiation macro policies.
