This invention relates to the field of natural resource surveying, monitoring, and accounting, specifically to a method for evaluating the efficiency of regional natural resource utilization that considers both flow and stock. The method includes: determining the spatial boundaries of the target area and defining the baseline time point; classifying all natural resources within the target area that fall under the scope of natural resource accounting into two categories: stock resources and flow resources; calculating the corresponding physical quantities of each stock resource and each flow resource; integrating all physical quantities of natural resources to the district / county scale to form district / county-level statistical results; processing the district / county-level statistical results using the entropy weight method to obtain comprehensive stock indicators and comprehensive flow indicators; constructing heterogeneity constraint factors based on the "three zones and three lines" framework; and evaluating the efficiency of natural resource utilization in each district / county using the comprehensive stock indicator as input and the comprehensive flow indicator as output through an SBM model incorporating heterogeneity constraint factors. This invention improves the accuracy of the accounting results.
