摘要
为探讨河长制实施背景下江西省水环境治理的成效,运用超效率SBM模型和Tobit模型,对2010年至2021年间江西省11个地级市的水环境治理效率开展测算评价及影响因素分析。研究结果表明,江西省水环境治理效率从2010年的0.948下降至2014年的0.792,然后增加到2021年的0.978,呈现出先下降后上升的趋势。此外,江西省水环境治理效率在空间分布上呈现出赣北优于赣中、赣中优于赣南的特点。自河长制实施以来(2016年至2021年),江西省的水环境治理效率提高了9.4%。分析还发现,经济水平和科技创新对江西省水环境治理效率呈正相关,而产业结构、资源禀赋和空间集聚则表现为负相关。提高经济发展水平和优化产业结构是江西省各地水环境治理效率提升的关键。研究成果可为江西省水环境治理效率提升、河长制的实施以及打造生态文明的“江西样板”提供科学依据。
The water environment management effectiveness of Jiangxi Province under the river chief system was investigated in this paper using the super-efficiency SBM model and Tobit model to evaluate and analyze the water environment management efficiency and its influencing factors in 11 prefecture-level cities in Jiangxi Province from 2010 to 2021.The results indicate that the water environment management efficiency in Jiangxi Province decreased from 0.948 in 2010 to 0.792 in 2014,and then increased to 0.978 in 2021,showing a trend of initial decline followed by a rise.Additionally,the water environment management efficiency in Jiangxi Province displays spatial variation,with northern Jiangxi outperforming central Jiangxi,and central Jiangxi outperforming southern Jiangxi.Since the implementation of the river chief system(2016-2021),the water environment management efficiency in Jiangxi Province has increased by 9.4%.It was also found that the economic level and technological innovation have positive correlations with the water environment management efficiency in Jiangxi Province,while industrial structure,resource endowment,and spatial agglomeration have negative correlations.The key to improving water environment management efficiency in various parts of Jiangxi Province lies in enhancing economic development levels and optimizing industrial structures.The research findings can provide scientific support for improving water environment management efficiency,implementing the river chief system,and creating an ecological civilization model in Jiangxi Province.
