Study on Measurement and Promotion of Water Resources Utilization Efficiency in Shandong-Henan Section of the Yellow River Basin
Improving the efficiency of water resource utilization is the key to achieving ecological protection and high-quality development in the Shandong Henan section of the Yellow River Basin.Taking 34 prefecture level cities in the Shandong Henan section of the Yellow River Basin from 2011 to 2020 as research objects,the SBM model was used to measure the efficiency of comprehensive water use,production water use,domestic water use,and ecological water use.Then,the GML index method was used to dynamically measure and decompose the water use efficiency in the four aspects,and the FGLS method was used to empirically analyze the influencing factors of the above efficiency.Research has found that the overall water use efficiency level of the river section is not high,and there are significant differences in water use efficiency.The order is domestic water use efficiency>comprehensive water use efficiency>production water use efficiency>ecological water use efficiency.The water use efficiency of each flow section in four aspects is ranked as follows:Shandong section>Shandong Henan section>Henan section;The GML index changes of production water are mainly determined by technological changes,while the GML index changes of comprehensive water,domestic water,and ecological water are mainly determined by both technological and efficiency changes;The level of economic development,sewage treatment capacity,urbanization process,number of scientific and technological achievements,and investment in science and technology are significantly positively correlated with water resource utilization efficiency,while industrial structure,water use structure,and water resource abundance are significantly negatively correlated with water resource utilization efficiency.
