摘要
基于"微笑曲线"理论,运用比较研究以及理论分析和数据预测相结合的方法,研究了农村劳动力流动对粮食安全的影响,估算出我国农村劳动力流动适度规模为0.8亿～2.0亿人。为保障粮食安全需要合理和适度的劳动力流动,要发展现代农业,稳定粮食生产和激励农村劳动力回乡建设新农村。
Based on the＂smile curve＂,this paper explores the impact of population movement on food security through comparison,theoretical analysis and forecast based on data.According to our estimation,the optimal migrant labor is in the range 80-200 million.In order to ensure national food security,we need to transfer surplus labor rationally and appropriately develop modern agriculture,stabilize grain production,encourage migrant labor return home to build a new countryside.
