摘要
通过对东北地区粮食生产动态变化的分析,采用CD生产函数和灰色关联分析等方法研究了东北地区粮食生产的主要驱动因子。研究发现:东北地区化肥投入对粮食总产贡献率最大,并呈增强趋势,依次是灌溉,呈减弱趋势,农机总动力贡献率不显著;相关性依次为化肥施用量、农机总动力和有效灌溉面积。在此基础上分析东北地区粮食生产持续高效发展面临的问题、发展趋势和战略选择,提出相应的对策和保障措施。
Based on the analysis of the dynamic changes of gain production in Northeast Region, applying the methods such as grey interrelated analysis and CD＇s production function. The main driving forces of grain production in the region were analyzed. The results indicate： chemical fertilizer input had the greatest contribution to grain, which had increasing trend, then the irrigation assuming weakening trend, the contribution of gross agricultural machinery was not notable; correlation order was put in the order of chemical fertilizer input, gross agricultural machinery and irrigation area. Lastly the author analyzed major problems that gain production in Northeast Region was faced with, development trend and strategy selection of sustainability and high efficiency of grain development, and put forward the corresponding countermeasures and measures.
