Abstract:

In the hilly-mountainous area in central China, agricultural land intensity is decreasing due to seasonal or all-year abandonment. This causes marginalization of agricultural land despite farmer-benefiting policies. By theoretical and empirical analysis, some reasons are found out as follows: 1. During the industrialization and urbanization process, farmers benefit more from urban employment than staying in farming. 2. The agricultural ecological environment of hilly-mountainous area is so bad that the farmland's marginal revenue decreases; 3. The farmer-benefiting policies are not the intended incentives in the hilly-mountainous area; ecological policies does not accord with agricultural policy, which aggravates local marginalization of agricultural land. Marginalization of agricultural land is rational behavior by farmers, but the process is significant to national food security and ecological construction. Marginalization of agricultural land in the hilly-mountainous area is driven by the multiple factors. In order to solve the phenomenon we must commence from the nature, economy, policy and so on to improve the agricultural environment, innovate agricultural organization system and technology, transform traditional farming, develop modern highly-effective characteristic agriculture, and increase marginal revenue of the farmland. In the meantime, national agricultural incentive policy should accord with ecological protection policy. The governments should adopt different subsidy methods in different areas, that is to say, they should adopt more special subsidy policies in the hilly-mountainous area under fragile ecology conditions.
