Abstract: China is one of the most populous countries in the world. Like other developing countries, huge population and its rapid growth are intensifying food insecurity. Cropland intensification driven by the government and rural households plays a key role in food production and provision at national level. However, since the implementation of reform and opening up, more and more rural workers have shifted to non-agricultural industries. Meanwhile, the wage increase rate of the ordinary labor in China is much higher than that of the prices of farm produce and also faster that of agricultural means of production. The increasing off-farm migration and rising wage make the shares of farm income in the total family income decline even further. So farmers' pursuance has turned from maximizing the output of land to maximizing the income of labor force with the development of market economy. The wage rise and the change of farmers' goal have exerted a great effect on agricultural land use in some parts of China, especially in the developed provinces of eastern China, which is mainly embodied in two aspects: decreases of multi-cropping index and labor input. Meanwhile, due to the high labor productivity, the agricultural restructuring with more vegetables, tea and fruit trees has been very apparent. And the spatial-temporal expansion of this trend will continue for a long time. To ensure grain production, the national grain subsidy programme introduced in 2004 has achieved initial targets, so future work and potential development in this field should be done to encourage scale management of farmland.
