Abstract: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.
