摘要
粮食生产是保障国家粮食安全战略的基石,而与其相关的适度财政支持可以兼顾公共财政资金有效利用、国家安全战略实施.结合水稻在粮食生产中的重要地位,基于2006-2021年中国省际面板数据,采用固定效应模型、中介效应模型和空间杜宾模型,实证分析财政支持对水稻总产量的影响机制及其空间溢出效应.研究发现:财政支持能够促进水稻总产量增长,但这种增产效应存在时滞;财政支持对水稻增产的中介效应主要通过扩大区域水稻生产规模实现;财政支持的增产效应存在负向空间溢出效应,导致水稻生产在空间分布上呈集聚趋势.鉴于水稻生产的空间异质性,从是否为粮食主产区来看,财政支持的增产效应在粮食主产区更显著;从经济发展水平来看,增产效应在东北地区更显著.因此,需要保持对粮食生产的财政支持力度,促进经营的规模化、效益化、可持续化的良性循环,防控财政支持政策的负向抑制作用,增量资金向包括东北地区的主产区倾斜.
Abstract
Grain production is the cornerstone of China's food security,and the moderate fiscal sup-port related to it can balance the effective use of public financial resources and the implementation of na-tional security strategies.In light of the important role of rice in grain production,this paper empirically analyzes the mechanism of fiscal support on total rice production and its spatial spillover effect based on the panel provincial data of China from 2006 to 2021,using fixed-effects model,mediated-effects model and spatial Durbin model.It is found that,firstly,financial support can significantly promote the growth of rice production,though with a time lag.Secondly,the mediating effect of support is mainly realized through expanding the scale of rice production,but the effect of financial support have a negative spatial spillover,which leads to the clustering trend in the spatial distribution of rice production.Thirdly,consid-ering the spatial heterogeneity of rice production,the yield-increasing effect of financial support is more significant in the main grain producing area from the point of view of whether it is the main grain produc-ing area or not.Fourthly,from the level of economic development,the yield-increasing effect is more sig-nificant in the Northeast region.Therefore,it is necessary to maintain the level of fiscal support for grain production,promote a virtuous cycle of scale,efficiency,and sustainability in farming operations,prevent the negative inhibitory effects of fiscal support policies,and allocate additional funds towards major grain-producing regions,including the Northeast region.
