英文文献：Supply Response Of Ukrainian Agriculture-乌克兰农业的供应反应
英文文献作者：Murova, Olga I.,Coble, Keith H.,Trueblood, Michael A.
英文文献摘要：
This study explores the impact of technical inefficiency on agricultural supply functions in Ukraine. Two models using a system of output supply and input demand equations were evaluated in this research: one without inefficiency included in the model and another with inefficiency included. A likelihood ratio test found that the model with inefficiency included was the preferred model in this case. Incorporation of inefficiency into the model increased output supply elasticities and did not dramatically change input demand elasticities. The own-price elasticities for grains, sugar beets, sunflowers, and potatoes showed inelastic positive signs that were statistically significant. The own-price input demands were negative and also inelastic; however, only fertilizer and fuels were statistically significant.
本研究探讨技术效率低下对乌克兰农业供应功能的影响。本研究以产出供给与投入需求方程为模型，分别评估无效率模型与无效率模型。通过似然比检验发现，在这种情况下，包含无效率的模型是首选模型。将无效率纳入模型增加了产出供给弹性，而没有显著改变投入需求弹性。谷物、甜菜、向日葵和马铃薯的自有价格弹性显示出非弹性的积极迹象，这在统计学上是显著的。自有价格投入需求为负且无弹性;然而，只有肥料和燃料在统计上具有显著性。
