用血“紧平衡”下的无偿献血激励探究

Exploring the incentives of voluntary blood donation under the “tight balance”

为探究公众献血意愿与物质激励的相关性,采用自制问卷于2018年4-5月对612名北京市辖区(县)居民开展无偿献血激励行为经济学实验,分别考察不同的物质激励条件下3组实验对象的献血选择,包括是否参与无偿献血、参与献血的类型以及献血量。实验结果显示,物质激励与个人献血意愿之间并不存在同向线性关系。过于强调物质奖励,甚至将其制度化,只会“南辕北辙”地破坏无偿献血的激励效果。

In order to explore the correlation between blood donation willingness of the public and material incentives,this paper conducted an economic experiment on 612 Beijing residents(districts and counties)from April to May 2018 using the self.designed questionnaire,and observed the choices of three groups subjects on blood donation under different material incentives,including willingness of blood donation without repayment, type of blood donation,amount of blood. The results showed that there was no linear relationship between material incentives and blood donation willingness of individuals. If we over.emphasize material rewards or even make blood donation a system,the incentive effect of unpaid blood donation would be destroyed.
