The impact of food price increases on caloric intake in China
利用2006年面板数据，研究世界食品价格上涨对中国两省贫困家庭消费和营养的影响，发现家庭通过转向廉价食品和政府干预使主食价格保持低位，总体营养影响较小。
World food prices have increased dramatically in recent years. We use panel data from 2006 to examine the impact of these increases on the consumption and nutrition of poor households in two Chinese provinces. We find that households in Hunan suffered no nutrition declines. Households in Gansu experienced a small decline in calories, though the decline is on par with usual seasonal effects. The overall nutritional impact of the world price increase was small because households were able to substitute to cheaper foods and because the domestic prices of staple foods remained low due to government intervention in grain markets.
