摘　　要：精准识别土地城市化对生态环境质量的影响,对推动城市绿色、高质量发展具有重大意义。论文以中国285个地级及以上城市为研究样本,基于“本地—邻地”研究视角,利用动态空间杜宾模型探究土地城市化对生态环境质量的影响,结果表明:(1)土地城市化对本地生态环境质量的提升具有显著的抑制作用,对邻地的生态环境质量产生了负向空间溢出效应。(2)城市间吸收能力差距会弱化土地城市化对邻地生态环境质量的空间溢出效应。城市间的吸收能力差距越小,土地城市化对邻地生态环境质量的负向空间溢出效应越小。(3)土地城市化对生态环境质量的影响存在时空异质性。在时间维度上,长期的负向影响效果大于短期;在空间维度上,中西部地区的负向影响效果大于东部地区。因此,应严格控制建设用地增量扩张,更新盘活城市中闲置或者低效利用的存量土地,进一步提高土地市场化水平,同时充分发挥市场、政府等多元主体在环境治理领域的作用,建立健全的生态环境治理长效机制,以改善土地城市化推进过程的生态环境质量。Accurately identifying the impact of land urbanization on the quality of the ecological environment is of great significance for promoting green and high-quality urban development.This study used the dynamic spatial Durbin model to explore the impact of land urbanization on ecological environment quality based on the local-neighboring area perspective and by taking 285 prefecture-level and above cities in China as research cases.The results show that:1)Land urbanization had a significant inhibitory effect on the improvement of the quality of the local ecological environment and a negative spatial spillover effect on the quality of the ecological environment of neighboring areas.2)The absorptive capacity gap between cities weakened the spatial spillover effect.The smaller the absorptive capacity gap between cities,the smaller the negative spatial spillover effect of land urbanization was on the ecological environment quality of neighboring areas.3)There were temporal and spatial heterogeneities in the impact of land urbanization on ecological environment quality.Temporally,the long-term negative impact is greater than the short-term impact and spatially,the negative impact in the central and western regions of China is greater than that in the eastern region.Therefore,we should strictly control the incremental expansion of construction land,renew and revitalize the idle or inefficiently used stock of land in the cities,further improve the level of land marketization,give full play to the role of multiple subjects such as the market and the government in the field of environmental governance,and establish a sound system and longterm mechanism for ecological environment governance to improve the quality of the ecological environment in the process of land urbanization.
