财政支农能一直提高农业技术进步吗 ——基于边际视角的省际面板门限模型实证研究

Can Financial Support Always Improve Agricultural Technology Progress——An Empirical Analysis of Provincial Panel Threshold Model Based on Marginal Perspective

摘要:

摘要：财政支农为推动农业现代化建设提供了重要的资金支持。本文基于边际视角采用2003—2017年面板数据，利用固定效应模型与面板门限模型重新审视了财政支农与农业技术进步之间的非线性关系。研究结果表明：（1）财政支农与农业技术进步之间存在倒U型关系，基于边际报酬递减规律下的财政资金并不能一直提高农业技术进步，稳健性检验下依然成立；（2）从禀赋差异来看，财政支农对农业技术进步的投入产出在地区间存在饱和效应；（3）引入社会资本参与和进行农业纵向开发，将有利于推迟财政支农拐点的到来。最后文章提出优化政府利用财政工具促进农业现代化发展，更好的运用“看得见的手”进行宏观调控的政策启示。

Abstract：Financial support of agriculture provides important financial support for the promotion of agricultural modernization.Based on the marginal perspective， this paper uses the panel data from 2003 to 2017， and uses the fixed effects model and the panel threshold model to re-examine the nonlinear relationship between financial support for agriculture and agricultural technological progress.This study provides these evidence:（1）There is an inverted U-shaped relationship between financial support for agriculture and agricultural technological progress. Fiscal funds based on the law of diminishing marginal returns cannot always improve agricultural technological progress， and it is still valid under the robustness test;（2）From the perspective of endowment differences， the input and output of financial support for agriculture on agricultural technological progress has a saturation effect among regions;（3）The introduction of social capital participation and vertical agricultural development will help delay the arrival of the turning point of fiscal support for agriculture.Finally， the article puts forward policy recommendations for optimizing the government's use of fiscal instruments to promote the development of agricultural modernization， and better use of "visible hands" for macro-control.
