摘要
以我国改革开放以来1978～2002年的相关数据为依托,运用计量经济学方法对影响我国粮食生产的主要因素进行了回归分析,最终得出结论:粮食播种面积对我国粮食生产的正面影响最大.同时,利用模型对提高我国的粮食产量进行了数量化分析.
In this article, by using the relevant data during 1978 - 2002 after the time of reform and opening - up of our country, regression analysis is given for the main factors, which have influence on the grain - production of our country. By check up of statistics, econometrics, economic meaning and model＇ s prediction, it is concluded finally that the planting area of grain has the most important facing influence on the grain - production of our country. At the same time, the models are utilized to analyze and increase the quantity of the grain＇ s yield of our country.
