英文文献摘要：
The paper presents preliminary results of the analysis of cost efficiency of peanut production in the South-Eastern region utilizing data from the 2001 Peanut Farm Costs and Returns Survey. Stochastic cost frontier analysis using both Cobb-Douglas and translog functional forms is used as the most suitable given data availability and the nature of the industry. Estimation results are used in a discussion of the likely farm-level effects of the 2002 Farm Act, which substituted quota support with marketing assistance loan program. Contrary to our expectations, quota ownership did not significantly affect cost efficiency, which implies that quota ownership is not a discriminating factor in considering the effects of the Farm Act. Other producer characteristics, such as farm size and operator's age have significant effect on cost efficiency. These findings, however, must be treated with caution, as the survey data appears to be too noisy, and the underlying assumptions may not be appropriate due to highly regulated nature of peanut production. We plan to further refine the data, as well as to use the DEA methodology which, due to its unrestricted and flexible nature, might provide more conclusive results and deeper insights.
本文利用2001年花生农场成本与收益调查的数据，对我国东南部地区花生生产的成本效率进行了初步分析。在给定数据可用性和行业性质的情况下，使用柯布-道格拉斯和跨对数函数形式的随机成本前沿分析是最合适的。估计结果用于讨论2002年《农业法》对农业可能产生的影响，该法案用市场援助贷款计划取代了配额支持。与我们的预期相反，配额所有权对成本效率的影响并不显著，这意味着配额所有权在考虑《农业法》的影响时并不是一个区别因素。其他生产者特征，如农场规模和经营者年龄对成本效率有显著影响。然而，必须谨慎对待这些发现，因为调查数据似乎过于嘈杂，而且由于花生生产的高度管制性质，潜在的假设可能不合适。我们计划进一步细化数据，并使用DEA方法，由于其不受限制和灵活的性质，可能会提供更有说服力的结果和更深入的见解。
