主销区农村劳动力外流与粮食安全:一致抑或分歧——以浙江为例

Labour Force Migration and Food Security in Major Food Sales Regions:Consensus or Conflict——A Case of Zhejiang

主销区粮食市场化后,自然禀赋和比较利益决定农户更多地选择放弃粮食生产而转移到投资回报率大的经济行为。主销区农村劳动力外流与粮食安全一致抑或分歧?本文认为在比较利益下主销区农村劳动力外流降低了粮食生产自给底线,但对经济增长和粮食获得能力增强做出了贡献,显示了二者的"一致"效应。主销区在一定的粮食自给底线基础上通过劳动力外流和粮食区际贸易可获得比较利益。

Since the food market reform market-oriented in the major food sales regions, majority farmers give up food production while choosing other high-return-rate economic behaviors because of natural endowments and comparative advantages. Do labor force migration and food security in major food sales regions have consensus or conflict？ The paper indicates that rural labors＇ outflow has lowered the bottom line of self-sufficicncy food. However, it has contributed to economic growth and food acquisition competence. The effects of ＂consensus＂ are somewhat conspicuous. Labor force migration and regional food trades can get comparative advantages above the bottom line of self-sufficiency food.
