Ecosystems provide the material and energy resources necessary for human development, improving people’s quality of life and well-being. Thus, enhancing the effectiveness of ecosystem services valuation has become a focal point of concern. Here, we adopt a perspective of equality and efficiency and construct a framework based on the ecological Gini coefficient (E-Gini coefficient) and the three-stage Data Envelopment Analysis-Malmquist (DEA-Malmquist) model, by evaluating the input of financial investments and human resources and the output of ecosystem service value (ESV) production, to assess the improvement of ESV in China from 2008 to 2020. The research findings reveal that the E-Gini during the study period remained consistently above 0.54, which is categorized as “high inequality”. ESV equality across different regions follows the order of northwest > south > north concerning economic and social development. Furthermore, through efficiency analysis, we find that there is room to improve the improvement efficiency of China’s ESV. Static efficiency analysis indicates that the average improvement efficiency of China’s ESV is low (0.331). This indicates that the input resources did not achieve the optimal ESV production. Dynamic efficiency analysis reveals that there is a 3.2 % decline in ESV improvement efficiency over the entire study period. Encouragingly, ESV improvement efficiency has been increasing annually since 2017. Moreover, there exists spatial heterogeneity in ESV improvement efficiency, with the northwest region showing significantly higher than the north and south. The research results can provide policy recommendations for ecological environmental governance, production efficiency, and ecological compensation. |
