摘要
以江西省蛋鸡供应链价格系统为研究对象,采用2002年1月～2013年11月蛋鸡供应链各环节产品价格的月度数据,运用脉冲响应函数动态分析了外部冲击对蛋鸡供应链价格传导机制的影响.研究表明,在外部冲击下会加剧江西蛋鸡供应链各环节的价格波动,特别是鸡蛋价格,但价格传递是不完全的,且对不同环节的价格的传导效率存在一定的差异性和滞后性.据此提出政策建议以应对外部冲击对江西省蛋鸡供应链价格传导的影响.
From the perspective of external shocks,the price transmission mechanism of laying hens supply chain in Jiangxi province was analyzed with impulse response function. The monthly price dates, included the whole supply chain link, covered the period from January 2002 to November 2013. What＇s more, the price transmission mechanism was determined by impulse response function. The results showed that external shocks would aggravate the price fluctuation of laying hens supply chain in Jiangxi,especially the egg price. However,the price transmission efficiency was incompl.ete and had some difference and lagged on the different links. Finally, some policy suggestions were put forward to deal with external shocks on the price transmission of laying hens supply chain in Jiangxi.
