摘要
为建设绿色高效农业,实现农业水资源可持续利用,在构建河南省农业水资源绿色效率和影响因素指标体系的基础上,利用SBM模型,分析了河南省农业水资源绿色效率的时空演变特征;运用Tobit模型,探讨了河南省农业水资源绿色效率的影响因素。结果表明:1)河南省农业水资源绿色效率整体呈现波动上升趋势,2019—2020年升幅最大,2014—2015年降幅最大;河南省各市农业水资源绿色效率存在显著差异,平顶山等9市、鹤壁等4市和三门峡等5市分别为低水平、中水平和高水平。2)河南省农业水资源规模效率和纯技术效率变化不大,各市规模效率多年均值均小于1,其中新乡最高、鹤壁最低;南阳等9市纯技术效率多年均值大于1,平顶山等9市小于1。3)河南省农业水资源绿色效率豫中呈现高(2013年)—低(2017年)—高(2022年)波动趋势,豫东、豫西、豫北和豫南均保持在高水平;河南省农业水资源绿色效率重心分布在郑州,整体从西南向东北迁移。4)经济发展水平、农业经济、城镇化水平、节水设施、资源禀赋等因素均有利于河南省农业水资源绿色效率的提升,而农作物种植结构、供水结构等因素则不利于其提升。
In order to build green and efficient agriculture and realize the sustainable utilization of agricultural water resources,based on the construction of the index system of green efficiency and influencing factors of agricultural water resources in Henan Province,the spatial and temporal evolution characteristics were analyzed by using SBM model.Using the Tobit model,the influencing factors were discussed.The re⁃sults showed that:a)The green efficiency of agricultural water resources in Henan Province showed a fluctuating increasing trend as a whole,with the largest increase from 2019 to 2020 and the largest decrease from 2014 to 2015.There are significant differences in the green efficien⁃cy of agricultural water resources among cities in Henan Province.The green efficiency of agricultural water resources in 9 cities such as Ping⁃dingshan,4 cities such as Hebi and 5 cities such as Sanmenxia is low,medium and high respectively.b)The scale efficiency and pure tech⁃nical efficiency of agricultural water resources in Henan Province are stable.The average scale efficiency of each city for years is less than 1,among which Xinxiang is the highest and Hebi is the lowest.The average pure technical efficiency of 9 cities for years such as Nanyang is greater than 1,and that of 9 cities such as Pingdingshan is less than 1.c)The green efficiency of agricultural water resources in central Henan shows a fluctuation trend from high(2013)to low(2017)to high(2022),and the green efficiency of agricultural water resources in eastern,western,northern and southern Henan remains at a high level.The center of gravity of the green efficiency of agricultural water re⁃sources in Henan Province is distributed in Zhengzhou,and the overall trend is to migrate from southwest to the northeast.d)Economic de⁃velopment level,agricultural economy,urbanization development level,water⁃saving facilities,resource endowment and other influencing factors are conducive to the improvement of green efficiency of agricultural water resources in Henan Province,while such as the structure of crop planting and water supply structure are not conducive to improvement.
