This paper utilizes the shift-share model and the prupose is to identify the growth of meat expenditure in a particular income group and divide changes into three factors using KOSIS data from 2010 through 2019 for ten income categories. The standard shift-share model aims at dividing the dynamics of a meat expenditure growth factor from a certain income group into three effects: the national growth effect, the sectoral mix effect, and the income decile effect. The results show that the national growth effect is positive in all ten income decile groups, though of different magnitudes, signaling that the whole consumption expenditure has a positive impact on meat expenditure. The national effect, however, is negative from 2017 to 2018 and 2018 to 2019, indicating that the staggering economic activity might depress not only the national consumption expenditure but the meat expenditure. The results also show that the sectoral mix effect is positive from 2011 to 2015, but is negative from 2015 to 2019. This indicates that the meat expenditure grows greater than the consumption expenditure in the period 2011-15, whereas the former falls behind the latter in the period of 2015 to 2019. The results also suggest that the income decile effect is negative for the lower income groups, but is positive for the higher income groups.
