Abstract :
In this paper, based on the data from 79 farms and 10 years QiXing farm in Heilongjiang reclamation area, we conducted correlation analysis and stepwise regression analysis for the selected 19 indicators related to agricultural machinery systems and agricultural production. Three optimal models were developed. The analysis demonstrated that agricultural machinery system of Heilongjiang reclamation area influences agricultural production, but the scale economic efficiency is not high and the large and middle scale agricultural machinery supporting is not enough. The efficiency of agricultural systems needs to optimize.
