The objective of this study is to 1) study the factors which an impact on the export quantity of Thai rice to Malaysia and the Philippines. 2) to Study of the change in the price of rice with Thai rice export quantity to Malaysia and the Philippines.3) A study of the nation's income changes, Malaysia and the Philippines, with Thailand's rice export quantity to the country of Malaysia, and the Philippines.Using secondary data. During 2000-2013, Using ordinary least square analysis by Objective 1 and the use of the method of calculation of elasticity of demand by objective 2 and 3. The study found that 1) Factors that affect the exports of Thai rice to the countries Malaysia are the Gross domestic product of Malaysia, exchange rate and the price of Thai rice exports. There are relationship in the opposite direction with the Thai rice export quantity to country Malaysia. The price of Vietnamese rice export and inflation it is a relationship in the same direction with the Thai rice export quantity to country Malaysia. 2)The factors affecting Thai rice export to the Philippines are exchange rate ,Gross domestic product of the Philippines ,Inflation and the price of Thai rice exports there are relationship in the opposite direction with the quantity of Thai rice exports to the Philippines. The remaining variable is Vietnamese rice export prices has the same direction in relation to the quantity of Thai rice exports to the Philippines. 3) Price elasticity of demand, it was found that Price elasticity of demand for Malaysia 0.62, Philippines 0.21 and the study on income elasticity of demand, it was found that income elasticity of demand in Malaysia and Philippines is less than one. Show that rice is necessary goods of Malaysia and the Philippines.
