摘要

本研究旨在利用2014年全国农业普查的数据,探讨银行和金融机构发放的农业信贷对哥伦比亚考卡谷农民香蕉产量的使用和影响。此外,它还评估了信贷的效果是否会根据农民倾向于投资的项目而有所不同。为此,由于学分不是随机授予的,本研究使用倾向得分匹配(PSM)方法来管理选择偏差。最初,通过probit模型发现,拥有自己的农业机械,使用化学肥料提高土壤肥力,非少数民族,受过某种基础或高等教育,可以增加获得农业信贷的可能性。另一方面,研究结果表明,信贷对作物产量有显著的正向影响(6.2%),但如果信贷投资于土地购买和收获后流程,其影响更大,产量分别增加39%和37%。另一方面,该研究还表明,如果信贷投资于与农业活动无关的项目,产量可能会减少10%。最后,建议实施一项公共政策,鼓励考卡谷的香蕉农更多地参与农业信贷计划,因为他们的参与率很低(10%),尽管可接受率很高(86%)。

The Impact of Agricultural Credit on Banana cultivation in Valle del Cauca, Colombia
This study aimed to explore the use and effect of agricultural credit disbursed from banks and financial institutions on banana yield in farmers from Valle del Cauca (Colombia) using data from the National Agricultural Census (2014). Additionally, it evaluated whether the effect of credit differs according to the items in which the farmer prefers to invest. For this purpose, because credits are not granted randomly, this research used the Propensity Score Matching (PSM) methodology to manage selection bias.  Initially, it was found through the probit model that having one's own agricultural machinery, using chemical fertilization to improve soil fertility, not belonging to an ethnic minority, and having some type of basic or higher education, increases the probability of obtaining an agricultural credit. On the other hand, the results suggest that credit has positive and significant effects on crop yield (6.2%), but the effect is greater if it is invested in land purchase and post-harvest processes, with an increase of 39% and 37% in yield, respectively.  On the other hand, this study also suggests that, if credit is invested in items not related to agricultural activity, yields can be affected with a 10% reduction. Finally, it is recommended that a public policy be implemented to encourage greater participation of banana farmers in Valle del Cauca in agricultural credit programs, given their low participation (10%) despite the high acceptability rate (86%).
