The reduction of hollow villages and optimal all ocation of inefficient operation and even idle waste of rural land resources are inevitable requirements of agricultural and rural modernization. By measuring the impact of rural land withdrawal of migrant workers, it is found that the land withdrawal of migrant workers will revitalize at least 23.33 million hm² of abandoned farmland and 2.13 million hm² of idle homestead. The necessity, importance and urgency of land withdrawal should be paid attention to. The withdrawal of rural land of migrant workers will have an important impact on the optimal allocation of cultivated land resources, agricultural production efficiency, international competitiveness of agricultural products prices, the promotion of agricultural supply-side structural reform and the realization of rural revitalization in China.
