Abstract：
The challenges posed by environmental pollution, water scarcity, and energy limitations resulting from industrialization and modernization pose significant threats to human habitats. Consequently, assessing ecological livability and delineating pathways for improvement carry considerable practical importance. Leveraging panel data encompassing 288 cities in China from 2010 to 2021, this study establishes an evaluation system for ecological livability, encompassing three dimensions: natural greenery level, residential comfort level, and environmental governance level. Subsequently, the study measures the ecological livability level and investigates the impact of \"sponge city\" pilots on ecological livability and their underlying mechanisms using a multi-period difference-in-differences model. Our findings underscore the substantial role of \"sponge city\" pilot projects in bolstering ecological livability, with robustness observed across various models and specifications. Specifically, human capital concentration and green technology innovation emerge as pivotal pathways through which \"sponge city\" pilots augment ecological livability. Moreover, the effectiveness of \"sponge city\" pilots varies across regions due to disparities in drought severity and water supply, with more pronounced effects observed in arid areas and cities facing water supply shortages. This research furnishes comprehensive theoretical and empirical underpinnings for comprehending the influence of \"sponge city\" pilots on ecological livability, offering valuable insights and recommendations to inform future efforts aimed at enhancing ecological livability and fostering sustainable development.
摘要：
环境污染带来的挑战，缺水,工业化和现代化导致的能源限制对人类栖息地构成了重大威胁。因此,评估生态宜居性和划定改善途径具有相当大的现实意义。利用2010-2021年中国288个城市的面板数据,建立了生态宜居性评价体系,涵盖三个维度：自然绿化水平，住宅舒适度，和环境治理水平。随后，该研究测量了生态宜居水平，并使用多周期差异模型研究了“海绵城市”试点对生态宜居性的影响及其潜在机制。我们的发现强调了“海绵城市”试点项目在增强生态宜居性方面的重要作用，具有在各种型号和规格中观察到的鲁棒性。具体来说,人力资本集中和绿色技术创新成为“海绵城市”试点增强生态宜居性的关键途径。此外，由于干旱严重程度和供水的差异，“海绵城市”试点的有效性因地区而异，在面临供水短缺的干旱地区和城市中观察到更明显的影响。本研究为理解“海绵城市”试点对生态宜居的影响提供了全面的理论和实证基础，提供有价值的见解和建议，为旨在提高生态宜居性和促进可持续发展的未来努力提供信息。
