中国东北地区粮食综合生产能力实证研究
Empirical Study on the Comprehensive Capacity of Grain Production
本文利用1989—2007年东北地区粮食生产的统计数据，运用Translog生产函数模型对东北地区粮食综合生产能力的影响因素进行了分析。研究结果表明，影响东北地区粮食综合生产能力的五种主要因素的产出弹性由大到小依次为粮食播种面积、农用化肥使用量、其他物质投入、粮食生产劳动力、粮食成灾面积。其中，粮食生产劳动力和粮食成灾面积的产出弹性为负。自1989年以来，东北地区粮食产量的提高主要得益于化肥的投入，其他物质费用次之，成灾面积增加对粮食产量的提高有负面影响。
In this paper, statistical data of grain production were used during 1989 to 2007in the northeast of China and the impact factors of grain production was analyzed through translog production function. The results showed there were five main factors affecting the comprehensive capacity of grain production in the northeast of China. In accordance with descending order of output elasticity, they were arable land、fertilizer、other material inputs、grain production labor and grain disaster area. The output elasticity of grain production labor and grain disaster area was negative. Since 1982, the increase of grain yield was due to fertilizer and other material inputs. The increase of disaster area had a negative contribution in grain production.
