Abstract
ABSTRACT To further explore the green water resources utilization efficiency (WRUE) in this basin, a corresponding method was designed. Firstly, a measurement index system for WRUE was studied and constructed. With this indicator system, the study introduced a data envelopment analysis model to analyze it, and then combined the relaxation variable analysis strategy to comprehensively analyze the accuracy of WRUE. The experiment outcomes indicated that in the WRUE of the Yellow River Basin (YRB), the pure technical UE changed the most and was in an effective utilization state. However, overall, the average values of scale efficiency and green UE within the basin were both below 1, indicating that it has not been fully utilized effectively. Besides, the average utilization efficiency of water resources in the upper, middle, and lower reaches was 0.51, 0.63, and 0.85, respectively. The analysis results prove that the measurement method designed in the research can effectively analyze the WRUE of the YRB, provide effective support for the efficient and circular development of the regional economy, and promote regional economic development.
