向農村發放政策性貼息小額支農貸款一直是學術界和各級政府比較公認的解決農村貧困人口，促進農村發展的有效途徑，從現有的理論上看，一定范圍內的小額貼息貸款的發放，會促進農業和農村的發展，提高農村貧困家庭的收入水平，而小額貼息貸款是不是能夠提高農戶的收入水平，貸款戶的增收情況同當地的平均增收額比較，效果怎樣，這是本文所要解決的問題，本文通過對貸款農戶的調查，在收集大量第一手材料的基礎上，將各縣市區所有被調查數據進行了匯總，統計出貸款戶收入變化情況以及與當地的平均增長額的對比情況，將被調查農戶的貸款額，投資領域進行了對比，並與當地非借款戶的當年收入增加額進行了比較。用定量比較和縱向比較的方法研究不同投資領域、不同貸款額、不縣域環境的貸款戶增收額及其相互關系。來說明財政貼息小額支農貸款對農戶收入的影響，分析政策性小額支農貸款對增收的影響因素，論述政策性貼息小額支農貸款的政策性缺陷及管理上的不足，並結合當今國內外政策性支農貸款的政策和管理方式，對我國政策性小額支農貸款的政策制定及管理模式提出了個人的一些見解，筆者認為發揮政策支農貸款的支農作用的根本是推進農村金融體制改革和政治體制改革，改善農村金融服務，創造一個競爭、規范的農村金融環境，有限的貼息貸款解決不了農民的信貸資金需求問題。分享友人
