收入、偏好与居民食物安全

Income,Preference and Food Safety of Residents

本文利用中国营养与健康调查提供的9省区面板数据,采用Probit模型,分析了2004—2009年收入不确定性、偏好对居民食物安全的影响,同时对城乡差异和区域差异进行比较。结果发现:收入不确定性对居民食物安全产生的负面影响要明显强于收入水平提高产生的促进作用;科学、合理的饮食消费习惯有待进一步养成;东部居民食物安全状况要明显好于中西部,城乡居民食物安全水平的差异主要体现在蛋白质摄入的营养需求上;我国总体食物安全框架的重点应该是在保证食物供给能力的基础上,平衡差距。

Using the panel data of China Nutrition and Health Survey among nine provinces between 2004 and 2009, the paper analyzed the relationship of income uncertainty, preference and food security, while the urban- rural gap and regional disparity were compared. The results showed that： income uncertainty evolved a much stronger role in worsening food security than low income levels; rational dietary habits needed to further developed; the situation of food security in the east of china was much better, the gap of food security between urban and rural residents mainly reflected in the protein intake on nutritional needs; the overall food security framework should focus on balancing regional disparities, on the basis of guaranteed food availability.
