實證結果顯示：稻作補貼、稻作收入、和地租對長期稻米生產調整比率均有負面的影響；農業所得率則有正面影響。Moreover, it is suggested to focus the production adjustment policy on the conversion of farmland in the non - primary - rice - producing areas and to choose proper crops to substitute for rice according to the characteristics of areas
此外，由於稻作收入及地租與生產調整比率呈反向關系，表示生產調整在稻米主產地及良質米產地推行不易，因此生產調整應著重在非稻米主產地，並根據地區特性，研擬適當的轉作作物，才能有效解決稻米供需失調的問題。Over time metal - roller milling was to spread to other grains including rice and to other parts of the world, often with equally impressive results
