Due to the close relationship between rice policy and the industrial development, this study attempts to understand the policy effects on rice economy, meanwhile, to explore the policy considerations behind policy evolution. Based on the estimated economic characteristics, this paper will recognize the policy difference by means of simulation of canceling purchasing policy with guarantee price or set-aside payment. The results indicate that the importance of purchasing policy with guarantee price is reducing while introduction of set-aside payment policy. However, maintain the purchasing policy with guarantee price still have some meaningful in price declaration, grasping rice for government inventory and stabilizing rice price.
Based on the empirical results of rice econometric model, this paper also shows that the effect of adjusting guarantee price on production and price are greater than adjustment in purchasing quantity per ha. The effect of rotation payment on rice production is statistically significant in the first crop, however, the effect of set-aside payment on production in the second crop is larger the first crop by four times. In the long run, it is expected a naturally decline trend in rice price, paddy rice planted area and production quantity, but fallow area will be increasing. Two-third of paddy rice area would concentrate in first crop. According to the simulation of policy adjustment, this paper finds that total quantity of brown rice would decrease 251,060 tons in one year and wholesale price would lower 1.05, 1.53 NT dollar respectively, if only abolish purchasing policy with guarantee price. Furthermore, plus with canceling set-aside payment, it is expected that wholesale price would lower 2.06, 2.86 NT dollar respectively, even the reduction level will expand. In addition, there are 160 thousands fallows area in total 260 thousands of fallows area are nothing to do with canceling set-aside payment or not, in other words, many areas are continually in state of fallow. Finally, this study also estimates set-aside expenditure multiplier is 1.23, and purchasing policy with guarantee price expenditure multiplier is only 0.43. Obviously, it is not an efficient way to improvement framers' income by purchasing policy with guarantee price.
