【摘要】：多哥农业生产以小农经营为主,由于农村缺乏必要的基础设施,农业产出低下,小农户难以获得信贷支持、现代技术、农资产品,难以有效利用知识和信息资源。作为多哥最主要的粮食作物,玉米种植面积占总粮食种植面积的47%以上,单产很低。同时,作为多哥人主要食用的谷物,玉米具有较大的食用价值和经济价值。由于玉米在多哥经济中具有十分重要的作用,因此研究多哥小农户玉生产力的影响因素十分有必要。本文的研究目的是分析多哥农业生产力的影响因素、农户的社会经济特征对农业投入的影响,以及种子、技术和道路基础设施在多哥农业生产中的作用。因此,最突出的问题是:在多哥,哪些因素影响玉米生产力?小农户面临的主要制约因素是什么?以及哪些相关的政策建议可以提高农业生产力?为了回答这些问题,本论文主要运用柯布-道格拉斯生产函数分析哪些因素影响了玉米产量以及生产率;运用Probit模型分析这些因素对化肥等农业投入品的影响。本论文在多哥每个区域抽样选择了一些农户进行调查。2015年,在多哥五大经济区,滨海区、高原区、中部区、卡拉区和草原区,共有408户小农户参加了调查。主要结论如下:1.收获面积、农户家庭规模、化肥投入量对玉米产量有显著影响。收获面积每增加1%,玉米产量增加0.99%;农户家庭规模每扩大1%,玉米产量增加0.05%;化肥投入每提高1%,玉米产量增加0.008%。2.农户所在区域对玉米产量影响的模型结果显示:中部区显著正相关。这可能表明,在中部区每增加1%的农民,玉米产量会增加12%。中部地区玉米产量受旱作天气影响显著,通过播种施肥,农户可以快速增加雨季的产量。3.Probit模型结果显示,耕地面积、受教育程度、推广服务和农户的收入对农资投入有显著影响,是显著正相关。
[Abstract]:Togolese agricultural production is dominated by smallholder farming. Due to the lack of necessary infrastructure in rural areas and the low agricultural output, it is difficult for small farmers to obtain credit support, modern technology and agricultural products. It is difficult to make effective use of knowledge and information resources. As the most important food crop in Togo, corn covers more than 47% of the total food area and yields are very low. At the same time, it is the main food grain for Togolese people. Maize is of great edible and economic value. As corn plays a very important role in the Togolese economy, Therefore, it is necessary to study the influencing factors of Togolese small-scale farmers' jade productivity. The purpose of this paper is to analyze the influencing factors of Togolese agricultural productivity, the influence of farmers' social and economic characteristics on agricultural input, and the seeds. The role of technology and road infrastructure in Togolese agricultural production. Thus, the most prominent question is: what factors affect maize productivity in Togo? What are the main constraints faced by small farmers? And what relevant policy recommendations can improve agricultural productivity? In order to answer these questions, this paper mainly uses Cobb-Douglas production function to analyze which factors affect maize yield and productivity. Probit model is used to analyze the effects of these factors on agricultural inputs such as chemical fertilizers. In this paper, some farmers were selected for investigation in each region of Togo. In 2015, in five major economic zones of Togo, coastal areas, highlands, central regions, A total of 408 smallholder farmers participated in the survey in Kara and grassland areas. The main conclusions are as follows: 1. Harvest area, household size, The amount of chemical fertilizer input has a significant effect on corn yield. For each increase of harvest area, corn yield increases by 0.99; with the increase of household size, the corn yield increases by 0.055.The yield of corn increases by 0.0088.2. for each increase of fertilizer input, the corn yield increases by 0.99. The model results of maize yield effects show that there is a significant positive correlation in the middle region, which may indicate that, For every 1% additional farmers in the central region, corn yield will increase by 12. The drought weather has a significant effect on maize yield in the central region. By sowing and fertilizing, farmers can quickly increase the yield of rainy season. 3. Probit model results show that the cultivated land area, education level, The extension service and farmers' income have significant influence on the input of agricultural material, which is significantly positive correlation.
