Model estimation results.

(1) BackgroundThis study explores the coupling and coordinated development of new urbanization and eco-efficiency and their interaction mechanisms from the perspective of efficiency, and it has significant implications for promoting high-quality development and surpassing in China’s regional development.(2) ObjectiveThe study aims to investigate the spatiotemporal distribution pattern of new urbanization efficiency and eco-efficiency and its coupling and coordinated development relationship.(3) MethodsUsing panel data from 2010 to 2020 for nine cities in Fujian Province, this study employs the undesired super-efficiency SBM model to measure the efficiency of new urbanization and eco-efficiency. Additionally, a spatial panel Durbin model is constructed to analyze the interaction effect between the two efficiencies.(4) ResultsDuring the study period, both new urbanization efficiency and eco-efficiency in Fujian Province showed a fluctuating upward trend, with higher efficiency in the southeast than the northwest, exhibiting significant spatial agglomeration effects. Despite high double efficiency coupling, coordinated development was low, evolving from near-disorder to barely coordinated. The high coupling and coordination areas were mainly concentrated in the southeast, with gaps between different regions gradually narrowing. There was positive interaction between dual efficiency in the same region, with new urbanization efficiency showing a positive spatial spillover effect on eco-efficiency. Conversely, the spatial spillover effect of eco-efficiency on new urbanization efficiency was not significant.

（1）背景本研究从效率的视角，探讨新型城镇化与生态效率的耦合与协同发展及其相互作用机制，对中国区域发展的高质量推进与超越具有重要意义。（2）目标本研究的目的是调查福建省新型城镇化效率与生态效率的空间分布模式及其耦合与协同发展关系。（3）方法本研究采用2010年至2020年福建省九个城市的面板数据，运用SBM模型的不希望超效率方法来衡量新型城镇化和生态效率。此外，构建空间面板Durbin模型以分析两种效率间的交互效应。（4）结果在研究期间，福建省的新型城镇化和生态效率均呈现波动上升的趋势，东南部地区效率高于西北部地区，显示出显著的空间集聚效应。尽管双高效率耦合较高，但协同发展水平较低，发展过程从近乎无序逐渐过渡至勉强协调。高耦合与协调区域主要集中于东南部，不同地区间的差距逐渐缩小。同一区域内双效率之间存在正向交互作用，新型城镇化效率对生态效率显示出正向的空间溢出效应。相反，生态效率对新型城镇化效率的空间溢出效应并不显著。
