ABSTRACT Drs Abhijit Banergee, Esther Duflo, and Michael Kremer won the 2019 Nobel Prize in Economic Sciences for their remarkable series of large-scale field experiments to lessen global poverty. The main theoretical framework that they employed was the diffusion of innovations research and practice paradigm (DOI) which has had a long presence in communication research dating back to the 1940s. Here, we reviewed the Nobel laureates’ article, ‘Using gossips to spread information: Theory and evidence from two randomized controlled trials,’ that is illustrative of how economists applied the communication theory of diffusion of innovations to their projects of social change. The present article poses questions and makes recommendations for similar future projects from a communication perspective.

将创新扩散的传播理论应用于经济科学：对2019年诺贝尔奖获得者进行的``利用八卦传播信息''实验的回应

摘要Abhijit Banergee博士，Esther Duflo博士和Michael Kremer博士因其一系列减轻全球贫困的杰出实地实验而获得了2019年诺贝尔经济学奖。他们采用的主要理论框架是创新研究和实践范式（DOI）的传播，该范式可追溯到1940年代，在传播研究中一直存在。在这里，我们回顾了诺贝尔奖获得者的文章“利用八卦传播信息：两个随机对照试验的理论和证据”，这说明了经济学家如何将创新传播的传播理论应用于他们的社会变革项目。本文提出了一些问题，并从沟通的角度为类似的未来项目提出了建议。
