摘要 城市是人类生产与生活的集中地和重要载体,因而也是能源消费和碳排放的关键主体,在建设低碳城市和发展绿色经济的政策工具箱中,提高碳生产率是最重要的抓手。基于此,本文在Cobb‐Douglas成本函数基础上构建了城市化与城市碳生产率关系的理论模型,并运用门槛回归检验了我国地级市层面人口城市化、土地城市化与城市碳生产率的动态关系。实证结果表明:人口城市化与土地城市化对城市碳生产率具有不同的阶段性效应,其中人口城市化与城市碳生产率呈现“强促进‐弱促进”的关系,拐点位于非农就业人口占比5.36%处;而土地城市化与城市碳生产率呈现“促进‐脱钩”的关系,拐点位于建成区面积占比1.09%处。分地区的实证结果从区域层面证明了该阶段性效应的稳健。该结论表明,当前我国大多数地级市均已越过以上两个门槛值,意味着低碳式城市化和科学合理的城市规划将是我国经济绿色低碳发展的必由之路。 Cities are the gathering place and essential carrier of human production and life,it is also the main subject of energy consumption and carbon emission.Thus improving carbon productivity is the most important starting point in the policy toolbox of building low‐carbon cities and developing green economy.A theoretical model of the relationship between urbanization and urban carbon productivity was built based on the Cobb‐Douglas cost function,then the dynamic relationship between population urbanization,land urbanization and urban carbon productivity at the level of China’s prefecture‐level cities was tested with threshold regression model.The empirical results show that population urbanization and land urbanization have different staged effects on urban carbon productivity.Specifically,the relationship between population urbanization and urban carbon productivity presents a“strong promotion‐weak promotion”relationship with the inflection point of 5.36%of population urbanization rate,while the land urbanization and urban carbon productivity showed a“promotion‐decoupling”relationship with the inflection point of 1.09%of the land urbanization rate.The regional empirical results prove the robustness of the research conclusions from the regional level.The results reveal that most prefecture‐level cities in China have passed the two thresholds,which means that low‐carbon urbanization and reasonable urban planning will be the only way to develop green economy in China’s cities.
