摘　　要：采用DEA模型测算2010—2019年河南省18个城市生态效率,借助核密度估计等方式探索其时空演变规律,利用线性回归方法识别驱动生态效率的影响因素。结果表明:(1)河南省城市生态效率总体呈现先下降后上升的变化趋势,2010—2014年为下行期,2015—2019年为提升期。(2)城市间生态效率存在明显差异,高值区逐渐由分散分布演变为"南部高北部低"的"C"字型分布,18个地市可根据生态效率变化情况分为保持有效、高位提升、中高位波动、低位爬升四大类。(3)人均GDP、经济外向度、交通便利度、环境要素、环境治理能力对河南省城市生态效率有正向促进作用,人口密度、产业结构、城镇化水平、资源依赖度对河南省城市生态效率有负向抑制作用。This study explored the spatio-temporal evolution and influencing forces of urban eco-efficiency in Henan.At first,eco-efficiencies of 18 cities from 2010 to 2019 were evaluated by using the DEA model.Then,the spatio-temporal changing trends were explored by means of nuclear density estimation.At last,multiple linear regression was used to identify the influencing factors driving ecological efficiency.The results show that:(1) The overall urban ecological efficiency of Henan Province shows a trend of first decline and then rise.The period from2010 to 2014 is the downward period,and the period from 2015 to 2019 is the improvement period.(2) There are obvious differences in eco-efficiency between cities,gradually evolving from a scattered distribution to a C-shaped distribution of "high in the south and low in the north".The 18 cities can be divided into four categories which including effective maintenance,high-level improvement,mid-to-high volatility and low-set climb.(3) Per capita GDP,economic outward orientation,transportation convenience,environmental factors,and environmental governance capabilities have a positive effect on the urban eco-efficiency of Henan Province.Population density,technological investment intensity,industrial structure,urbanization level,and resource dependence have a negative effect on urban eco-efficiency.
