以原油为代表的能源价格变化是近年来影响国际农产品价格波动的主要因素。借助纽交所原油期货和大连大豆期货、玉米期货周数据,利用Johansen协整分析、向量自回归以及脉冲响应等计量方法对国际原油期货市场与大连商品期货市场的大豆和玉米等农产品价格传导关系、传导方向和路径以及传导效率等进行了深入的分析。结果发现:从长期来看,国际原油期货价格与国内玉米期货价格呈现同向波动,原油期货价格每波动1%,则国内玉米价格波动0.186%;从短期来看,国际原油期货价格对农产品价格的传导并不显著。原油期货价格与国内玉米期货价格之间存在单向因果关系,原油期货价格与国内大豆期货价格之间存在双向因果关系,大豆期货市场的运行效率比玉米期货市场更为有效,国内大豆的定价权在进一步增强。
以原油為代錶的能源價格變化是近年來影響國際農產品價格波動的主要因素。藉助紐交所原油期貨和大連大豆期貨、玉米期貨週數據,利用Johansen協整分析、嚮量自迴歸以及脈遲響應等計量方法對國際原油期貨市場與大連商品期貨市場的大豆和玉米等農產品價格傳導關繫、傳導方嚮和路徑以及傳導效率等進行瞭深入的分析。結果髮現:從長期來看,國際原油期貨價格與國內玉米期貨價格呈現同嚮波動,原油期貨價格每波動1%,則國內玉米價格波動0.186%;從短期來看,國際原油期貨價格對農產品價格的傳導併不顯著。原油期貨價格與國內玉米期貨價格之間存在單嚮因果關繫,原油期貨價格與國內大豆期貨價格之間存在雙嚮因果關繫,大豆期貨市場的運行效率比玉米期貨市場更為有效,國內大豆的定價權在進一步增彊。

Fluctuation of crude oil prices is the most important factor affecting international agricultural products price in recent years. We focus on price movements between crude oil futures and a series of agricultur- al commodities. A comparative framework is applied to identify changes in relationships through time and various cointegration methodologies and causality tests. The results indicate that co- movement is a dynamic concept and that some economic and policy development may change the relationship between commodities. In the long run, when the OIL price increases 1%, the CORN price fluctuates 0. 186% ; however, in the short term, no sig- nificant relations exist in prices between agricultural commodities and OIL; And international crude OIL futures and domestic soybean futures do not undergo similar fluctuation. All these suggest that the effect of international crude OIL futures on domestic corn futures is more significant than on domestic soybean futures.
