基于供应链视角的政府扶贫效率研究

Research on the Efficiency of Governmentpoverty Alleviation Based on the Perspective of Supply-chain

在电商扶贫中,政府常采用农业技术推广、政府采购、投入补贴三种农业帮扶模式,何种方式更有效是一个非常重要的问题。本文基于供应链视角,使用主从博弈模型对比分析供应链成员的决策行为,之后从农户收益最大化角度分析政府扶贫的效率,并讨论应用情景。结果表明:政府进行基础设施建设与农业帮扶均可提高农户收入;消费者的扶贫偏好会增加农产品价格与农户利润,且能够提高三种帮扶模式的效率;农户投入成本较小时,投入补贴模式扶贫效率最高,而农技推广与政府采购模式更稳定,在农户投入成本较高时更有效;政府资金有限时,投入补贴模式效率最高,当资金量中等时,农技推广模式效率最高,若资金比较充裕,则政府采购模式较为有效。

The government has introduced relevant agriculturalsupport policies,such as agricultural technology extension,government procurement,and agricultural subsidies to better fight poverty.It is a very important question which way is more effective.This paper uses Stackelberg game theory to construct an e-commerce agri-products supply chain model and analyzes the decision-making behavior of supply chain members.Afterward,it analyzes the efficiency of government poverty alleviation based on the principle of increasing farmers’ income and discusses the application scenarios.The results show:Both the government’s infrastructure construction and agricultural support policy can increase farmers’ income.Consumers’ poverty alleviation preferences will increase the prices of agricultural products and farmers’ profits,and can effectively improve the efficiency of the three agricultural support policies.When farmers’ investment costs are negligible,The agriculture subsidy model has the highest poverty alleviation efficiency,while the agricultural technology extension and government procurement model is more stable and more effective when the investment cost of farmers is higher.When government funds are limited,the agriculture subsidy model is the most efficient,when the funds are moderate,the agricultural technology extension model is more effective,and when funds are abundant,the government procurement model is more effective.
