The problem, which the conversion of cropland to forest program faced derived from the dual sector structure of China. The problem is how to solve the inconsistency of demand elastic and utility function of the same land between the developed region or industry and the less-developed ones. To solve this problem, the government must harmonize the conflict between the multi-demand about forest of the developed region and the developing demand of the less-developed region. But now, the policy input of the conversion of cropland to forest program is not sufficient but only imperative to ensure the success of the program. Some actions should be taken to combine with the program to ensure the long-run good effect.
