摘要
对2003—2012年黑龙江垦区粮食产量及相关影响因素数据进行了实证分析.选取化肥施用量、农业机械总动力、粮食播种面积、农业劳动力数量、有效灌溉面积和农药施用量等指标,建立了C-D生产函数模型,并采取逐步分析的方法,确定了影响黑龙江垦区粮食产量的主要因素是化肥施用量和粮食播种面积,对建立的模型进行了检验,得出误差符合标准.对黑龙江垦区粮食生产提出未来发展方向和相应的对策.
Based on the grain output and the data of related affecting factors in Heilongjiang reclamation area during 2003--2012, the empirical analysis has been carried out. Selected six index which including the applying quantity of chemical fertilizer, the total power of agricultural machinery, the grain acreage, the agricultural labor force, the effective irrigation area and the applying pesticide content, then the C-D production function model was established, and took the stepwise analysis method to confirm the main factors which effect the grain output of farming area in Heilongjiang reclamation area. They are the applying quantity of chemical fertilizer and the grain acreage, and after inspecting the model, it was concluded that error conforms up to the standard. Put forward the future developing direction and corresponding policy of grain production for the farming area in Heilongjiang reclamation area.
