以60个国家1971 - 2012年的平衡面板数据为样本，基于阈值模型检验了城市化与温室气体排放的关系。结果发现，城市化率与温室气体排放量之间的关系总是正的，这表明，无论城市化率有多高，城市化都将不可避免地导致温室气体排放量的增加。当城市化率超过23.59%或温室气体排放量超过42, 287 kt CO2当量时，城市化对温室气体排放的影响更大。此外，城市化路径影响城市化与温室气体排放之间的关系。当100万以上城市群人口占总人口的比例高于20.01%或第一大城市人口占城市人口的比例高于48.27%时，城市化与环境污染的正相关关系更加显著
Taking the balanced panel data of 60 countries from 1971 to 2012 years as a sample, the relationship between urbanization and greenhouse gas (GHG) emissions was checked based on the threshold model. It was found that the relationship between the urbanization ratio and GHG emissions was always positive, suggesting that urbanization will inevitably lead to an increase in GHG emissions, irrespective of how high the rate of urbanization is. However, when the urbanization ratio passed 23.59% or the GHG emissions exceed 42,287 kt of CO2 equivalent, urbanization will have more impact on GHG. Also, the urbanization paths influence the relationship between urbanization and GHG emissions. When the population in urban agglomerations of more than 1 million of total population is higher than 20.01% or the population in the largest city of urban population is above 48.27%, positive correlation between urbanization and environmental pollution will be more significant
