Abstract
Abstract High-quality economic development has become a goal in China. The measurement of eco-efficiency provides a comprehensive assessment for such development. However, the measurement of eco-efficiency is still based on the traditional data envelopment analysis model, and the analysis of eco-efficiency does not consider spatial correlation. In this study, the SuperSBM model considering undesirable output is used to measure eco-efficiency at the provincial level in China. Then, Moran’s I index is adopted to investigate the spatial correlation of eco-efficiency. Results show that the eco-efficiency in China generally presents a downward trend. In terms of area, the central and western regions have generally declined, except for the eastern region. The reason for the decline in eco-efficiency is the continuous decline in technical efficiency. A significant positive spatial correlation of eco-efficiency exists at the national level. High-high and low-low agglomerations of eco-efficiency exist in China. High eco-efficiency is mainly distributed in Inner Mongolia, Heilongjiang, Hebei, Beijing, Tianjin, Henan, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong, and Hainan.
