Price effects of residents' consumption carbon emissions: Evidence from rural and urban China

Price policy applied to specific products may mitigate consumption carbon emissions (CCE). Nevertheless, the extent to which price effects, such as carbon taxes, differ across income groups and between rural and urban areas in China remains uncertain. With unbalanced provincial panel data from 1999 to 2020, we estimated the demand elasticities of eight major groups of consumer goods and services across income groups separately in rural and urban areas of China, using the Quadratic Almost Ideal Demand System (QUAIDS) and the Exact Affine Stone Index Implicit Marshallian demand system (EASI) in this study. The estimated price elasticities were then used to predict the impact of different price policies on CCE. The results show that taxing the wealthiest individuals and subsidizing the poorest individuals in both rural and urban areas have a beneficial impact on the reduction in CCE. Moreover, expanding transfer payments can further facilitate reductions in CCE. Our findings suggest that achieving CCE equality can be realized through intra-urban and intra-rural transfers, as well as urban-rural transfers achieved by taxing urban residents and subsidizing rural residents.
