碳排放约束下中国城市绿色发展及空间分布特征

Evaluation of Green Development in Chinese Cities Under Carbon Emission Constraints: A Static and Dynamic Quadrant Analysis

摘要:

以279个样本城市为研究对象，构建包含非期望产出的整体SBM（slack-based measured）方向性距离函数模型，以此测度中国城市绿色发展及其空间分布特征。相比于现有研究，文中从静态视角和动态视角分别测度绿色发展水平和效率，其中静态视角关注于城市绿色发展的现状，动态效率测度则有助于理解绿色发展随时间的变化趋势。利用四象限分析法直观地揭示了不同城市的绿色发展状况及趋势，并识别出在绿色发展水平和效率上表现出优势和劣势的城市。从城市层面来看，中国绿色发展状况存在向好趋势，但呈现出较高的空间差异性特征。少部分城市既具有较高的静态发展水平又同时具有高的动态效率，中国城市高质量绿色发展将出现两级分化态势。

Abstract:

This paper， using an overall SBM-DDF （slack-based measured directional distance function） model on 279 sample cities， measures and evaluates green development in Chinese cities from both static and dynamic perspectives. The static analysis focuses on the current state of green development， while dynamic efficiency provides insights into development trends. Quadrant analysis identifies cities with strengths and weaknesses in green development， offering valuable insights for inter-city learning， competition， and cooperation， and the formulation of targeted strategies. Although green development in China is improving from a city-level perspective， it exhibits significant spatial variability. Only a small number of cities have both high static development levels and high dynamic efficiencies. In the future， China’s high-quality green development is likely to experience a two-tier differentiation.
