英文文献摘要：
This paper investigates the impacts of export controls in Russia and Ukraine on wheat world market price transmission during the 2007/2008 global food crisis. Russia and Ukraine aimed to reduce wheat exports induced by extraordinarily high world market prices to secure sufficient wheat supply on the domestic markets. Utilizing a Markov-Switching vector error correction model (MSVECM), we find that the temporary export restrictions induced negative effects on wheat markets in Russia and Ukraine. Although instability increased on the world markets itself, we have shown that the increase in the market instability was particularly pronounced in Russia and Ukraine. Also, the export restrictions dampened price transmission to the farmers’ prices, which pushed the growers’ prices below their long-run equilibrium level. Thus, investment incentives in wheat production which could result from high world market prices were foregone.

本文研究了2007/2008年全球粮食危机期间俄罗斯和乌克兰出口管制对小麦世界市场价格传导的影响。俄罗斯和乌克兰旨在减少因世界市场价格过高而导致的小麦出口，以确保国内市场有充足的小麦供应。利用Markov-Switching vector error correction model (MSVECM)，我们发现临时出口限制对俄罗斯和乌克兰的小麦市场产生了负面影响。虽然世界市场本身的不稳定增加了，但我们已经表明，市场不稳定的增加在俄罗斯和乌克兰尤其明显。此外，出口限制抑制了价格对农民价格的传导，从而使种植者的价格低于长期均衡水平。因此，世界市场价格高企可能带来的小麦生产投资激励措施被放弃了。
