英文文献作者：Shaik, Saleem,Helmers, Glenn A.
英文文献摘要：
System of input demand functions is estimated to examine the impact of farm program payments on farm economic structure. Influence of farm program payments on input resource use for the time periods corresponding to the thirteen farm bills in effect since 1938 is also examined. Empirical application to Nebraska agriculture sector for the period 1936-2004 indicate positive impact of farm program payments on farm real estate, breeding livestock and other inputs. Negative influence of farm program payment on the use of farm equipment, farm labor, farm inputs, chemicals and energy was observed during the same period.
估计了投入需求函数系统，以检验农业计划支付对农业经济结构的影响。本研究还考察了自1938年以来实施的13项农业法案所对应的时期内，农业项目支付对投入资源使用的影响。对1986 -2004年期间内布拉斯加州农业部门的实证应用表明，农业计划支出对农场房地产、饲养牲畜和其他投入产生了积极影响。在同一时期，我们观察到农业项目支付对农业设备、农业劳动力、农业投入、化学品和能源使用的负面影响。
