基于超效率SBM模型和Malmquist生产率指数的河北省微咸水资源利用效率评价
Evaluation of brackish water resources utilization efficiency in Hebei Province based on super efficiency SBM model and Malmquist productivity index
摘要
Abstract
Brackish water is an unconventional water resources,and its effective utilization can signifi-cantly alleviate the contradiction between supply and demand of water resources.Exploring the utilization efficiency of brackish water resources is of great significance for realizing sustainable utilization of water resources,promoting economic and social development,as well as protecting ecological environment.Based on the super efficiency SBM model and Malmquist productivity index,we measured and analyzed the utilization efficiency of brackish water resources in Hebei Province from 2012 to 2022 from static and dynamic aspects.Brackish water consumption for agricultural,industrial and domestic use,and brackish water cost per cubic meter were selected as input indices,the proportion of brackish water substituting fresh water,the change of crop yield under brackish water irrigation,the added value of agricultural irri-gated area,and the added value of brackish water industry were used as output indices.The results show that the average utilization efficiency of brackish water resources in Hebei Province during 2012-2022 is 0.575,and the most efficient utilization areas of brackish water resources are mainly concentrated in Can-gzhou City and Xingtai City in central and northeast Hebei.Among them,Huanghua City has the highest comprehensive efficiency,while Yongqing County has the lowest.In recent years,the total factor produc-tivity index(TFP)of brackish water resources utilization in Hebei Province is 1.115,which shows an upward trend with fluctuations.Technological progress is the dominant driving factor,followed by effi-ciency change.Although the overall utilization efficiency of brackish water resources in Hebei Province is low,there is still significant room and potential for improvement.In addition,technological progress has played an important role in improving the utilization efficiency of brackish water resources.In the future,it is necessary to continuously increase the investment in scientific and technological innovation,research and development in the field of brackish water utilization in Hebei Province,and optimize resource alloca-tion,so as to further improve the total factor productivity.关键词
