Abstract:

Improving urban resources and environmental efficiency is of great significance to the high-quality development of the river basin. This article uses the SBM super-efficiency model based on undesired output and the Malmquist-Luenberger index, the resources and environmental efficiency of cities above prefecture level in the Yellow River Basin in 2000, 2005, 2010, 2015 and 2017 were measured and calculated, and their spatial and temporal characteristics were analyzed in combination with the kernel density function. Finally, the Tobit model is used to measure the main influencing factors of urban resources and environmental efficiency, which is expected to provide a scientific reference for improving the quality and efficiency of the resources and environment of the study area. The results show that the urban resources and environmental efficiency of the Yellow River Basin has generally shown a U-shaped change trend, and the overall level is not high. The number of non-DEA effective cities is much larger than that of DEA effective cities. Urban total factor productivity has shown a downward trend, but efficiency changes and pure technical efficiency changes show an improvement trend; industrial structure and government intervention are positively correlated with resources and environmental efficiency. The level of economic development, urbanization, energy consumption and environmental governance have a negative effect on the resources and environmental efficiency.

Key words: Yellow River Basin, resources and environmental efficiency, undesired output, super-efficiency SBM, Malmquist-Luenberger index
