摘要
在回顾相关文献的基础上,运用协整分析方法,从价格传导和产量的负向冲击2个方面研究了进口大豆和棉花对种植收入的影响。结果显示,进口大豆对国内大豆的价格传导作用非常大,虽然大豆的进口对国内大豆的产量产生了负向冲击,但是部分年份进口大豆价格的大幅上涨会使大豆的种植收入上升;而进口棉花对国内棉花价格的传导作用较小,对国内棉花产量的负向冲击作用也不明显,进口棉花对国内棉花种植收入的影响主要是通过价格传导途径体现的。
Based on review of relative literatures, this paper uses cointegration analysis to analyze the impact of imported soybean and cotton on growing income from two aspects of price transmission and negative impact of output. The result shows that the transmission effect of imported soybean is very obvious. Although the imported soybean has caused negative impact on the domestic soybean output, the significant increase of price of imported soybean has also resulted in the increase of growing income in several years. While the transmission effect of imported cotton on domestic cotton is not obvious , nor is negative impact on domestic cotton output. The impact of imported cotton on domestic cotton growing income is mainly reflected from price transmission.
