| 摘 要： | 在简要分析1949-2010年黑龙江省粮食产量变化的基础上,从生产条件、农业投入、政策保障、产出效益4个方面选取29个指标,采用通径分析法分析影响黑龙江省粮食产量变化的驱动因素及变化机理。结果表明:1)黑龙江省粮食产量总体呈增长趋势,60年间主要经历五个增长期和三个下降期;2)农业投入和产出效益是黑龙江省粮食产量变化的主要驱动因素,而生产条件和政策保障是黑龙江省粮食产量变化的次要驱动因素。

| Abstract: | Based on briefly analyzing of grain production of Heilongjiang Province from 1949 to 2010,we collected 29 indices from four aspects of agriculture investment,production conditions,policy support and output efficiency,and analyzed the driving factors and change mechanism by path analysis.The results show that:(1)The trend of total grain increased significantly,it mainly experienced five growth and three decline periods during 60 years.(2)Agriculture investment and output efficiency were the main driving factors,production conditions and policy support were the subordinate factors. |
