中文摘要：

在农地非农化中，市场机制与政府机制都是不可缺少的配置手段，但它们都存在失灵，只有引入民主议会机制，并使之与市场机制、政府机制协同发挥作用，才能促进农地适度非农化配置。我国要实现农地适度非农化目标，需要清除农地产权不明晰、政府垄断、宏观监控机制僵化等障碍，建立起市场机制、政府机制和民主协商机制有机融合的体制机制。

英文摘要：

Through theoretical analysis to appropriate farmland conversion, we found that market and plan are all indispensable means in the farmland conversion, but both of them are not perfect; the parliamentary democracy mechanism playing coordination role with market mechanism and plan mechanism need to be introduced to promote the appropriate farmland conversion. To achieve appropriate farmland conversion in China, it is necessary to clear out the obstacles such as unclear farmland property rights, the government monopoly, the bad macro-control mechanism, and to build an organic integration mechanism with market mechanism, plan mechanism and parliamentary democracy mechanism based on the different types of farmland conversion.
