财政投入和金融支持对农民农业增收贡献的比较

基于2000~2013年省级面板数据，运用固定效应模型和分位数回归模型考察了财政投入和金融支持对提升农民农业收入的影响，并采用因素分解法比较两者对农民农业增收的贡献大小，继而通过两步固定效应回归、分组回归和替换变量回归三种方式检验结果的稳健性，均得出一致结果，即财政投入和金融支持均促进农业增收，其中财政投入贡献更大，此外大规模的土地投入和完善的基础设施建设也有利于农业收入提高。

Comparison of Contribution of Fiscal Input and Financial Support to Increasing Farmers' Agricultural Income

Through the fixed effect model and quantile regression, this paper uses the provincial panel data from 2000 to 2013 to study the effect of fiscal input and financial support on increasing farmers'' agricultural income, and then compare their respective contributions to agricultural income growth using factor decomposition method. In addition, the paper tests the robustness through two-step fixed effect regression, grouped regression and alternative variable regression. Based on all models, we find that fiscal input and financial support both promote enhancing farmers'' agricultural income, of which fiscal input contributes more. Besides, large-scale farmland and excellent infrastructure construction also help to increase agricultural income.
