## Abstract

This study aims to (1) analyze the factors affecting demand, supply of domestic and import of beef in Indonesia and (2) calculate the magnitude of the elasticity of demand, supply of domestic and import of beef in Indonesia to change in its price. The data used are secondary data time series at period 1991-2009. The Analysis used in this study is simultaneous equation econometric modelswith analytical methods Two Stage Least Square (2SLS) in double log form of equation to determine the factors and the elasticity of demand and supply of beef in Indonesia. The results showed that demand of beef in Indonesia affected by the real domestic price of beef, the real price of fish, the real price of chicken, income per capita,and the change of population,while domestic supply of beef in Indonesia by the real domestic price of beef and ratio of cattle population to technology of artificial insemination. While import of beef in Indonesia affected by the real price of beef imports, import tariffs and the exchange rate. Own price elasticity of demand of beef is elastic, that is equal to 1.26, while the own price elasticity of domestic supply of beef is inelastic, that is equal to 0.81. While the import price elasticity of imports of beef imports is elastic, that is equal to 1.40. key words: demand, suppy, beef, elasticity, simultaneous equation
