This research considers that the socio-economic and demographic vairables are important to the determination of meat expenditure pattern in Taiwan. The 16,434 samples of household expenditure collected by the Directorate General of Budget, Account & Statistics are used to estimate a household meat expenditure forecasting model. Future meat demands are then estinated and forecasted. It is further argued that trade liberalization would affect meat demand structure. The calculation of the possible impacts of a lower and unified beef import tariff on meat demand is performed by adopting past and current reseasch results. The simulation results show that beef import liberalization has the greatest influence on beef sector. For the change on meat demand structure, the market share of pork consumption will decrease while the shares of beef, chichen, and duck consumption will increase, It is concluded that the government should causiously consider the hog policy together with possible beef import liberalization.
