摘要

本研究的主要目的是利用数据包络分析法分析哈萨克斯坦阿拉木图地区玉米生产中资源利用水平的效率。在研究过程中，通过面对面调查的比例抽样，从阿拉木图地区96名种植玉米的农民中收集数据。研究结果表明:各农场玉米生产面积平均为112.63 ha。测定玉米平均产量为961192.91 kg，每公顷玉米产量为8534.07 kg。农民收到的平均玉米价格为0.080美元/公斤。每公顷玉米的平均生产成本计算为222.18美元。每公顷玉米生产的平均净利润已确定为462,64美元。研究表明，农民选择和使用投入品的最重要标准是投入品价格。根据效率分析结果，计算出96个玉米农户在规模报酬不变假设下的平均效率为0.74，在规模报酬变假设下的平均效率为0.95。采用数据覆盖法对玉米生产投入品的利用效率进行了分析。在数据包络分析中，数据分析采用CRS (Constant Return to Scale)和VRS (Variable Return to Scale)模型，并在分析中分别采用这两种模型进行估计。根据两种模型的假设，得到了输入效率的结果。在输入驱动模型方法中，可以用最少的输入资源实现目标结果。经确定，农民选择和使用投入物的最重要标准是投入物的成本。根据效率分析结果，96个玉米农户的平均效率在规模收益不变的情况下为0.74，在规模收益可变的情况下为0.95。

ANALYSIS OF INPUT USAGE EFFICIENCY IN CORN PRODUCTION: A CASE STUDY FOR ALMATY REGION OF KAZAKHSTAN

The main objective of the study is to analyze the efficiency of resource use levels in corn production using the Data Envelopment Analysis method in Almaty region, Kazakhstan. In the course of the study, data were collected from 96 farmers growing corn in the Almaty region by proportional sampling using a face-to-face survey. According to the research results: the average of maize production area in the farms is 112.63 ha. It was determined that the average maize production amount was 961192.91 kg, and the maize yield per hectare was 8534.07 kg. The average corn price received by the farmers is 0,080 $/kg. Average maize production cost per hectare was calculated as 222,18 $. Average net profit per hectare from maize production has been determined as 462,64 $. It has been determined that the most important criterion for the farmers in selecting and using inputs is the input price. According to the efficiency analysis results, the average efficiency of 96 maize farmers was calculated as 0.74 under the assumption of constant return to scale and 0.95 under the assumption of variable return to scale. A data coverage method was used to analyze the efficiency of the use of inputs in corn production. In Data Envelopment Analysis, data were analyzed according to the CRS (Constant Return to Scale) and VRS (Variable Return to Scale) models, and estimates were made according to both models in the analysis. According to both model assumptions, efficiency results for the input were obtained. In an input-driven model approach, target results can be achieved with minimal use of input resources. It was determined that the most important criterion for farmers in the selection and use of inputs is the cost of inputs. According to the results of the efficiency analysis, the average efficiency of 96 corn farmers was calculated as 0.74 assuming constant returns to scale and 0.95 assuming variable returns to scale.

期刊介绍： Interciencia is the monthly multidisciplinary publication of the INTERCIENCIA Association. It is dedicated to stimulate scientific research, its humanitarian use and the study of its social context, specially in Latin America and the Caribbean and to promote communication between the scientific and technological communities of the Americas. Interciencia has been published uninterruptedly since 1976. Its Founding Director, Marcel Roche (endocrinologist and sociologist of science) was editor until 2008, and thereafter Miguel Laufer (neurobiologist) has been in charge. It has been included since 1978 in the Science Citation Index and other international indexes, and since 2008 it maintains an open access electronic version with material from 2005 onwards. The priority areas of the journal, without exclusion of other areas, are Agronomy, Arid Lands, Food and Nutrition, Biotechnology, Ecology and Environment, Energy, Innovation and Technology Transfer, Marine Resources, Non-renewable Resources, Science Education, Science Policy, Study and Sociology of Science, and Tropical Forests. Interciencia publishes in Spanish, Portuguese and English research and review articles, communications and essays, all of which are subjected to peer review. Additionally, it includes non-refereed sections such as Editorial, Letters to the Editor, Open Town Hall, Book Reviews and Upcoming Events. All the material submitted to the journal for publication and accepted by the Editorial Committee in view of its quality and pertinence is subjected to review by peer specialists in the corresponding fields of knowledge. Neither the INTERCIENCIA Association, nor the journal or the institutions to which the authors belong carry responsibility for the contents.
