Transportation carbon emissions and their driving factors

The data primarily derive from official statistical publications and authoritative sources, including the China Statistical Yearbook (2006–2019), China Transportation Statistical Yearbook (2006–2019), China Energy Statistical Yearbook (2006–2019), China Population and Employment Statistical Yearbook (2006–2019), China Urban and Rural Construction Statistical Yearbook (2006–2019), the Ministry of Transport’s Statistical Bulletin on the Development of the Transportation Industry, the National Bureau of Statistics’ Statistical Bulletin on National Economic and Social Development, and the National Energy Administration’s Monthly Energy Statistics Bulletin. For limited missing data in certain years, an autoregressive moving average (ARMA) model was applied to impute missing values, ensuring data continuity
