This paper attempts to uncover the veil of government restrictions on farm land usage. One important inference from the discussion is that lifting the restrictions probably would not affect the size of national farm land as well as the aggregate of classified farm land. Wise use of farm land and gradual elimination of price support are necessary in response to the challenge of market access. The impact of lifting farmland use restrictions alone would be insignificant but together with alternative scheme of support, the final outcome on the total and distribution of farm land would be quite different.
