摘要
在分析中国务农人口老龄化现状与特征的基础上,通过对1995-2011年全国、东部、中部和西部数据进行实证研究,揭示了务农人口老龄化对粮食增产的影响。研究表明:务农人口老龄化和劳动力投入减少对粮食增产都起到负作用;务农人口老龄化和劳动力投入减少的负作用主要由科技水平、土地和化肥的贡献来弥补;经济发展在一定程度上可以减弱务农人口老龄化对粮食生产所带来的负面影响。
Based on the analysis of present situation and features of farmer population aging in China, via empirical research of data in overall national, eastern, central and western during 1995-2011, this paper revealed the impact of farming population aging on grain production. Study has shown that both farming population aging and labor input play a negative role on grain production. And these negative impacts can be compensated by the contributions of technological level, land and fertilizer. Furthermore, to some extent, economic development can offset the negative impact of farming population aging on grain production.
