摘　　要：运用协整分析、格兰杰因果关系检验、VAR模型、脉冲响应函数以及岭回归方法,研究要素价格变动对农业能源效率的影响。实证研究结果表明:能源要素、资本要素以及劳动力要素价格与农业能源效率存在长期的均衡关系。3种要素价格都是农业能源效率的格兰杰原因,而反向的格兰杰因果关系则不存在。能源价格和劳动力价格对能源效率产生正向影响,其上涨1%分别使能源效率提高0.341%和0.364%;而资本价格对能源效率的影响却相反,资本价格下降1%会可使能源效率提高0.084%。应进一步推进要素价格的市场化改革,形成有效的价格约束机制;同时应充分利用价格手段,加快农业产业结构升级,提高农业能源效率。Cointegration analysis,granger causality test,VAR model,impulse response function and ridge regression are adopted to study the impact of factor price changes on agriculture energy efficiency. The results show that： There is a long-term equilibrium relationship between energy factor, capital factor and the price of factor labor and agricultural energy efficiency; Three factor prices are Granger-cause of the agricultural energy efficiency,while the reverse Granger causality does not exist; Energy and labor prices have a positive impact on energy efficiency, which improve energy efficiency by 0. 341% and 0. 364% when raised by 1%, respectively. On the contrary, capital prices have a negative impact on energy efficiency,which improve energy efficiency by 0. 084% when decreased by 1%. In order to improve agricultural energy efficiency by the price means we should further promote market-oriented reform of factor prices to form an effective price restraint mechanism and accelerate the upgrading of industrial structure of agriculture.
