Resumo: | On the basis of grey correlation analysis, 8 factors impacting grain production prominently as follows are selected to establish indices system: yield per unit（X1）, grain planting area（X2）, agricultural labor forces(X3), the total power  of agricultural machinery (X4), using amount of fertilizer(X5), the damaged area of crops（X6）, effective irrigation area（X7）, and agricultural fixed assets investment（X8）. According to the relevant data of Inner Mongolia Statistical Yearbook from 1988 to 2008, we use the method of grey correlation analysis to analyze the factors impacting grain production in Inner Mongolia, quantify the correlation degree of the total grain output and all factors, and finally conclude the impacting capacity of all factors on grain production in the light of correlation degree value. The results show that yield per unit still is the principal factor impacting the total output of grain in Inner Mongolia; the area of grain planting and the area of affected crops are the two most important factors responsible for the decrease of grain output; effective irrigation area the total power of agricultural machinery are the two primary factors impacting the increase of grain output; the using amount of fertilizer shows dwindling impact on grain production; agricultural fixed assets investment still hovers at the minuscule impact degree on grain production.
