Research on Spatial Difference, Distribution Dynamics and Influencing Factors of Urban Water-Use Efficiency in the Yellow River Basin

This study creatively uses the Dagum Gini coefficient, Kernel density estimation, and Markov chain to measure spatial difference distribution dynamics of urban water-use efficiency in Yellow River Basin from 2008 2018 accurately also analyzes its formation mechanism by using Spatial Durbin Model. The results show that hypervariable intraregional differences constitute main source regional whole basin; dynamic evolution characteristics different reaches are different. factors have a non-negligible impact; urbanization process population spillover effects negative state interaction; effect upgrading industrial structure is positive; direct openness both positive. In order improve Basin, it necessary comprehensively promote new urbanization, upgrade structures, energy conservation emission reduction, construct business environments, establish an inter-regional coordination mechanism.
