Spatio-temporal Heterogeneity in the Performance of Rural Revitalization in Chifeng City of China: Based on a Range-wide EBM-GML Model

To solve the problems of rural revitalization performance research, a quantitative model non-oriented range wide EBM (Epsilon-Based Measure)-GML (Global-Malmquist) based on VRS (Variable Returns to Scale) conditions including non-desired outputs is constructed. A comprehensive spatio-temporal heterogeneity research index system also Taking typical in Chifeng City as an example, panel data from 2016-2020 are selected for empirical analysis, conclusions and countermeasures suggested follows: 1) In general, increases significantly during five-year period, with significant heterogeneity. The overall analysis shows that value 0.683 2016 2020. highest 1 lowest 0.389. growth rate year by year, average annual 4.46%. 2) From 2020, GML 1.174, show ing increasing trend. Based change index, can be classified into three types: Continuous improvement, fluctuating improvement decline. 3) Niujiayingzi, Guandongche, Zhaidamu, Qiangangtai have degree technological progress.
