摘要 本文在对农业资本利润率变动趋势分析的基础上,运用资本利润率变动相关理论,构建影响农业资本利润率变动的MLR模型,基于1978—2007年时间序列数据统计检验结果表明:在较长时期内农村经济增长率、资本劳动比、农户数、农业产出品价格水平与农业资本利润率之间具有稳定的协整关系,农业经济增长、资本劳动比、农业产出品价格水平与资本利润率具有显著的正向关系,而农户数与资本利润率则呈现负相关关系,并通过格兰杰因果检验。 Based on the analysis of the changes in the agricultural capital profit margin, and the statistical results of 1978--2007 time-series data, applying capital margin fluctuation related theories, and constructing an MLR model that influences the fluctuation of agricultural capital profit margin, we conclude that the growth rate of rural economy has a stable cointegration relationship with agricultural capital profit margin in a longer term, the price of agricultural output has a significant positive relationship with capital profit margin, and the capital labor ratio, the number of farmers and capital profit margin form a negative relationship. Some brief countermeasures and suggestions are presented at the end of this article.
