摘要
作为农业支持保护制度的重要政策工具,农业补贴政策在实现粮食增产和促进农民增收上发挥了重要作用,但部分“黄箱”补贴的存在可能通过扭曲市场资源配置而加剧农业污染。研究结果表明:总体上,农业补贴促进了粮食增产和农民增收,但加剧了农业面源污染,农业补贴政策面临着多重目标实现的激励困境;农业补贴通过提高农业生产要素(农业机械、农药、化肥)投入水平而促进了粮食增产,具有降低农业劳动力投入的“要素替代效应”,但不存在通过扩大粮食种植规模而促进增产的渠道;农业补贴的收入增长效应是通过生产性收入和工资性收入增加的渠道来实现的;在种植结构“趋粮化”的背景下,农业补贴通过提高粮食作物种植比例的“逆向结构效应”加剧了污染,但规模效应与技术效应均不显著。
As an important policy tool of agricultural support and protection system,agricultural subsidy policy plays an important role in increasing grain production and increasing farmers’income.However,some“yellow box”subsidies may aggravate agricultural pollution by distorting the allocation of market resources.The results show that:on the whole,agricultural subsidies promote grain production and farmers’income,but aggravate agricultural non-point source pollution;agricultural subsidy policy is faced with incentive dilemma of multiple objectives.Agricultural subsidies promote grain production by increasing the input level of agricultural production factors(agricultural machinery,pesticides,chemical fertilizers),which has the“factor substitution effect”of reducing agricultural labor input,but there is no channel to promote the increase of grain production by expanding the scale of grain planting.The income growth effect of agricultural subsidies is realized through the increase of productive income and wage income.Under the background of“grain oriented”planting structure,agricultural subsidies aggravate the pollution by increasing the proportion of grain crops,but the scale effect and technical effect are not significant.
