与世界上许多其他国家一样，中国政府制定了到2020年实现单位GDP二氧化碳排放量比2005年减少40%-45%的碳排放目标。在中国的一些地区，短期经济需求主导了城市规划，而在其他地区--特别是近年来--重点已经转移到城市发展的质量上。本文以2004年至2013年的省级面板数据为基础，重点研究了土地利用质量以及土地城市化质量与碳排放之间可能存在的因果关系。结果表明：在全国范围内，碳排放与LUQ之间存在双向的长期因果关系，这意味着两者是共同决定的，并且同时相互影响。在恢复均衡的情况下，东部地区恢复速度最快，中部地区次之，西部地区最后。此外，值得注意的是，LUQ为减少碳排放做出了贡献，表明正在进行的产业结构调整和绿色发展已经生效。此外，我们还推断中部地区的节能潜力最大。我们进一步提出，在《新型城镇化规划(2014-2020年)》实施过程中，应重点推进低能耗程度和节能降耗。
The Chinese government, like many others around the world, has set carbon targets that by the time of 2020, to achieve a 40–45% decrease in CO2emissions per GDP compared with that of 2005. In some parts of China, short-term economic needs have dominated urban planning, while in other areas—especially in recent years—emphasis has shifted to the quality of urban development. This paper contributes to the literature as placing emphasis on the quality of land use as well as detecting possible causal links between land urbanization quality (LUQ) and carbon emissions using panel data from at provincial level from 2004 to 2013. The results show that: There is bidirectional long-run causal relation between carbon emission and LUQ on the national scale, which implies that the two are jointly determined and that they simultaneously affect each other. As the case of recovery to the equilibrium, Eastern regions have the fastest speed, followed by the Central and the Western ranked at last. Further, what worth noting is LUQ contribute to reducing carbon emissions, indicating the ongoing industrial restructuring and green developments have come into force. Moreover, we deduce that the Central region has the highest potential for energy conservation. We further propose that emphasis should be placed on promoting the degree of LUQ and energy conservation in the implementation during the New-type Urbanization Plan (2014–2020).
