财政支农支出与农业经济增长关系的实证研究——以安徽省为例

农业是国民经济的基础，它具有天生的弱质性和广泛的外部性，因此，农业的发展离不开国家财政的支持。通过选取安徽省1988-2010年农业产出和财政支农支出的相关数据作为样本，根据柯布一道格拉斯生产函数模型和Barro（1990）财政支出自然效率法则，对安徽省财政支农支出与农业经济增长之间的关系进行实证研究后发现，安徽农业产出与财政支农支出之间存在着长期稳定的均衡关系，安徽省财政农业投入最优规模为11．7％。政府应继续加大财政支农投入，保持农业经济的稳定增长；严格依据《农业法》的规定，建立财政支农稳定的增长机制；加强财政支农资金的管理，提高财政支农资金使用效率。
