Land resources provide stable support for economic development in China. However, due to the scarcity of land, the contradiction between agricultural land protection and construction land expansion is prominent. Under such circumstances, optimal allocation of land resources between agricultural and nonagricultural uses is vitally important. In view of the fact that land resources are indispensable inputs for production activities in agricultural and nonagricultural sectors, reducing the efficiency loss of land resource allocation between agricultural and nonagricultural uses is the only way to optimize the process. Counties are the basic administrative units in China, and their improvement of allocation efficiency will help optimize nationwide land resource allocation. This paper constructs models for estimating county-level land resource allocation efficiency from the perspective of sustainable development and searches for countermeasures to improve allocation efficiency. W County is used as an example to demonstrate how to choose these targeted countermeasures. It is concluded that the best way to optimize county-level land resource allocation between agricultural and nonagricultural uses can be found by estimating allocation efficiency from the perspective of sustainable development.
土地资源为中国经济发展提供了稳定支撑。然而，由于土地稀缺，农业用地保护与建设用地扩张之间的矛盾日益突出。在这种情况下，土地资源在农业和非农用途之间的优化配置至关重要。鉴于土地资源是农业和非农生产活动不可或缺的投入要素，减少土地资源在农业和非农用途之间配置的效率损失是优化这一过程的唯一途径。县是中国的基本行政单位，提高其配置效率有助于优化全国土地资源配置。本文从可持续发展的角度构建了县级土地资源配置效率的评价模型，并探寻了提高配置效率的对策。以 W 县为例，演示了如何选择这些有针对性的对策。结论是，从可持续发展的角度来评价土地资源的配置效率，可以找到优化县级土地资源在农业和非农用途之间配置的最佳途径。
