黄河九省(区)水资源绿色效率时空格局与影响因素研究
Research on the Spatial-Temporal Patterns and Influencing Factors of Water Resources Green Efficiency in Nine Provinces of the Yellow River Basin
摘要
Abstract
In order to explore the water resources green efficiency in cities of nine provinces(regions)of the Yellow River Basin,based on the SBM-DEA model and Tobit model,the spatial-temporal patterns and influencing factors of water resources green efficiency in 99 prefec-ture-level cities in nine provinces(regions)of the Yellow River Basin were analyzed.The results show that a)the overall water resources green efficiency in nine provinces(regions)of the Yellow River shows a stable rising trend,the lower reaches enjoy the highest average an-nual efficiency,the lower reaches of the Central Plains Urban Agglomeration and the Shandong Peninsula Urban Agglomeration rank the top,while the upper reaches of the Lanzhou-Xining Urban Agglomeration and along the Yellow River in Ningxia Urban Agglomeration are relatively poor.b)The water resources green efficiency in nine provinces(regions)of the Yellow River has a significant spatial agglomeration distribu-tion,and the cities with high efficiency are mainly concentrated in the economically developed and main grain-producing provinces in the low-er reaches.The water resources green efficiency shows a significant positive spatial autocorrelation with agglomeration and spillover effect.c)The scale of the primary and tertiary industries,water resources endowment and water-saving level have positive effects on the water re-sources green efficiency,while foreign direct investment has a negative effect.关键词
