• Paddy multifunctionality
• Compensating variation
• Production possibility curve
• Green subsidy
• Substitution cost method

The study synthesizes the spatiotemporal changes of the multifunctionality and benefit of Taiwanese paddy. The internal and external economic values of the paddy are quantitatively determined. Nationwide as well as regional variation of multifunctionality and benefits from 1999 to 2007 were considered. The substitution cost method was adopted to quantify the external economical values of rice paddy. Moreover, the compensating variation concept was applied to appraise the rational green subsidy of rice paddy in Taiwan. The result shows that the multifunctional benefits of rice paddy from 1999 to 2007 reduce 55, 18, 31, 13, and 28% in north, center, south, east regions, and nationwide of Taiwan, respectively. The reduction is mainly attributable to the significant decrease of rice-planting area. The external benefit may be further diminished if the fallow area increases continuously. In order to maintain the multifunctionality of rice paddy, we appraise a reasonable green subsidy to the cultivated paddy farmers. According to the results of the amount of green subsidy evaluated by the compensating variation concept, the estimated green subsidy is 21,000 NT$/ha for the nationwide paddy farmers. The government may consider to award the appraised green subsidy to paddy farmers directly for the sustainable management of rice paddy in Taiwan.
