财政支农与农业经济增长的实证分析

在Granger因果检验法验证财政支农支出增长和农业产出增长关系的基础上,运用生产函数测定财政支农各类支出的边际产出效应,并从财政支农政策制定和执行两方面探讨财政支农支出结构偏差的原因。主要结论是:农业公共产品投入不足极大地制约着中国农业可持续增长的潜力;为最大限度地提高财政支农资源的配置效率,必须大幅度增加农业科技投入,适度增加农业基础设施投入,压缩农业事业费支出,并在政策层面上进一步改革和完善财政支农政策的制定和执行机制。

Empirical Research of the Fiscal Expenditure on Supporting Agriculture for Agriculture Economic Growth

Based on Granger-Causality test to the relationship of fiscal expenditure on supporting agriculture and agriculture economic growth,in this paper production function was used to mensurate the marginal production effect of fiscal expenditure on supporting agriculture,and the cause of structure warp of fiscal expenditure was discussed from two aspects: constitution and executive of fiscal expenditure on supporting agriculture policy.The main conclusions were: insufficient investment to agriculture public goods restricted greatly the potential of continuable growth of agriculture.To improve maximally the allocation effect of fiscal expenditure,we should increase the investment to agriculture research sharply,and reform and optimize the constitution and executive of fiscal expenditure on supporting agriculture policy.
