| 内容提要 | 基于资源在不同部门的配置机理及结构变迁特征，补贴可以在一定条件下改变要素的相对价格，进而影响资源在不同部门之间再配置。理论模型表明，农业收入补贴和价格补贴能改变相对价格，从而影响劳动供给。但如果补贴较小，无法改变农业生产和非农生产的比较收益，补贴以收入效应为主，可提高农户的福利水平，而替代效应和产出效应不明显。为印证理论结论，选取安徽省岳西县进行重点调查，通过入户调查方法，获取家户的微观调查数据。结果表明，农业补贴提高了农户福利，但对农业生产影响有限。采用顺序逻辑模型的检验进一步证实，农业补贴部分提高了要素投入、单位产量和农户的福利水平，但农业生产技术效率没有显著提升。影响农户生产投入和积极性的主要原因在于农产品价格相对较低，补贴不足以弥补生产资料价格上涨。 |
| Abstract | Through resources reallocation and structure change among sectors, subsidies can change relative factor prices and affect resources allocation. The theoretical model shows that agriculture income subsidies and price subsidies will change relative prices and affect labor supply. However, if the subsidy is small, it can’t change comparative revenue between agriculture and non-agriculture activities where income effect dominates substitution/output effect. A survey in Yuexi District, Anhui Province, China has been conducted. It shows that subsidies improve living standards of farmers, but just tiny effect on agriculture production. Empirical test with Ordered Logistic Model confirms that subsidies increase inputs, unit outputs and farmers’ welfare, but no significant effect on productivity. Low incentive to increase input is due to low prices of agricultural products and subsidies. |
