Abstract: This paper, with 2001 to 2010 statistical yearbook data, using the panel data model, analyses Chinese rural labor outflow to the food production effects of different areas of rural from the provincial level, in order to understand the rural labor outflow of the different region and its effect on grain production level. The conclusion:(1)“Lewis turning point”has come in China's eastern and central regions, China's eastern and central regions, and agricultural manpower capital and grain yield was positively correlated, indicating rural labor outflow is not conducive to the long-term grain production in the two areas.（2）“Lewis turning point”has not come in China's western region,and agricultural human capital and grain yield was negatively related, indicating rural labor outflow is conducive to the development of grain production in western region.（3）As for the whole country,“Lewis turning point”has come, and agricultural human capital and grain yield was positively correlated, which the large-scale rural labor outflow is not conducive to the sustainable development of food.

摘要： 本文借助2001年至2010年相关统计年鉴数据，利用面板数据模型，从省级层面重点分析中国农村劳动力流出对不同空间区域农村粮食生产的影响，以期了解不同区域农村劳动力流出情况及其对粮食生产影响的程度。得出的研究结论：（1）我国东部和中部“刘易斯转折点”已经到来，我国东部和中部地区农农业人力资本与其粮食产量呈正相关，说明这两个地区农村劳动力流出不利于其粮食生产的长期发展。（2）我国西部“刘易斯转折点”还没有出现，我国西部地区农业人力资本与其粮食产量呈负相关，说明西部地区农村劳动力流出有利于其粮食生产的发展。（3）就全国整体而言，“刘易斯转折点”已经到来，农业人力资本与粮食产量呈正相关，说明农村劳动力大规模流出则不利于粮食的可持续发展。
