摘要：

本文在农业生产函数的框架下,利用1995-2009年间中国省际面板数据研究了我国农业部门劳动力投入的经济增长效应。为避免生态学谬误导致的忽略变量偏误,本文根据第一产业的特征把自然条件纳入了生产函数分析框架中。研究结果表明,整体而言,我国农业劳动力对经济增长的贡献率并不显著;近年来,农业劳动力投入与经济增长的关系呈现新的趋势,由于"刘易斯拐点" 的逐步呈现,劳动力逐渐体现出生产要素所固有的稀缺性和边际产出价值,农业劳动力对经济增长的贡献开始凸显。

Under the frame of agricultural production function,this paper looks into the growth effect of agricultural labor input using the Chinese provincial panel data between 1 995 and 2009. To avoid the omitted-variable bias resulted from ecological fallacy, the changes of natural conditions are accommodated into the production function in accordance with the features of primary industry. It is shown in the empirical result that the agricultural labor input is not significantly related to economic growth as a whole.However,some new trend could be seen from the relationship between agricultural labor input and growth in recent years. Since the Lewis Turning Point is looming upon,the scarcity and marginal product value of labor appears,thus showing its economic growth effect.
