論文導讀
文章運用微觀調查數據、無條件分位數回歸模型（UQR）和OB分解方法研究了中國家庭碳足迹的不平等，研究發現中國家庭碳足迹在城鄉、區域、收入組别以及各分位數等方面均存在嚴重不平等現象，且呈擴大趨勢。從微觀層面來看，家庭碳足迹不平等以及加劇主要來自于高碳家庭和中等碳足迹家庭之間的差異，除收入、城鄉、教育等家庭特征外，生活方式改變對于中國家庭碳足迹不平等以及變化具有重要的影響。文章認為需要在應對氣候變化過程中提高家庭碳足迹的公平問題，促進公平轉型，要特别注意生活方式對家庭碳足迹及不平等的影響，文章為中國和其他發展中國家的碳減排政策設計提供了有益的參考。
論文摘要
The significant achievements in economic growth and urbanization in China have recently led to substantial increases of and great inequality in household carbon footprints (HCFs). To achieve efficiency and justice in emissions reduction, policymakers need to fully understand the sources of HCFs and identify the major causes of carbon inequality. By applying the Unconditional Quantile Regression (UQR) model and decomposition method to the Chinese household survey data, this paper investigates the distributional features of HCFs and their determinants. We find that HCFs are unevenly distributed due to differences in the volume and pattern of consumption, which are further determined by household characteristics and lifestyles. The intertemporal lifestyle changes have played a major role in the rise of HCFs inequality measured by various quantile emissions differentials. In addition, considerable increases in HCFs come from the high carbon emission groups, and most of the HCFs inequality stems from the 90–50 emissions differential. To transform the current carbon-intensive economy, policies are required to enhance environmental equity and encourage low-carbon lifestyles.
