摘要
把握生态效率的规律和特征有利于优化资源要素投入,推动地区高质量发展.运用超效率SBM模型对2011~2021年河南省18个地级市的生态效率值进行测算,其次采用空间自相关、Dagum基尼系数、Markov链方法分别探究河南省生态效率的空间集聚特征、区域差异和转移规律特征.结果表明:河南省生态效率整体上呈现出波动上升的趋势,大部分地级市的生态效率都呈现出增长的趋势.河南省生态效率总体上表现出明显的空间分异和连片成团分布特征,呈现出“西北低,东南高”的空间分布格局.河南省生态效率为正空间自相关,且空间集聚效应逐渐增强.河南省生态效率的总体差异较为稳定,区域间差异是主要的差异来源并不断增大,豫北地区内部各地级市之间生态效率的发展差异最大且逐渐增加.河南省生态效率等级转移概率最大的是在同类型之间,存在“两头较中间稳定,总体变化趋势为向上”的特征.研究成果可为制定生态效率提升策略提供科学依据.
Grasping the laws and characteristics of ecological efficiency is conducive to optimizing the input of resource elements and promoting high-quality regional development.In this paper,the superefficiency SBM model was used to measure the ecological efficiency values of 18 prefecture-level cities in Henan Province from 2011 to 2021,and then the spatial autocorrelation,Dagum Gini coefficient and Markov chain methods were used to explore the spatial agglomeration characteristics,regional differences and transfer law characteristics of ecological efficiency in Henan Province,respectively.The results showed that:(1)The ecological efficiency of Henan Province showed a fluctuating upward trend as a whole,and the ecological efficiency of most prefecture-level cities showed an increasing trend.(2)On the whole,the ecological efficiency of Henan Province showed obvious spatial differentiation and contiguous cluster distribution characteristics,showing a spatial distribution pattern of"low in the northwest and high in the southeast".(3)The ecological efficiency of Henan Province is positively spatially autocorrelated,and the spatial agglomeration effect is gradually increasing.(4)The overall difference of ecological efficiency in Henan Province is relatively stable,and the inter-regional difference is the main source of the difference and is increasing,and the development of ecological efficiency among prefecture-level cities in northern Henan is the largest and gradually increasing.(5)The highest probability of eco-efficiency grade transfer in Henan Province was among the same types,and there was a characteristic of"the two ends are more stable than the middle,and the overall change trend is upward".The research results can provide a scientific basis for formulating eco-efficiency improvement strategies.
