新冠疫情信息对养猪户生产意愿与行为的影响——来自中国的证据

doi:10.1016/j.jia.2023.11.034

摘要/Abstract

摘要：

基于2020年和2021年的随机实验和跟踪调查数据，本文探究了新冠疫情信息对养猪户生产意愿的影响。研究结果显示，养猪户在收到关于新冠疫情的信息时，扩大生产规模的意愿显著降低。2020年，处理组的农户被告知“由于没有疫苗，新冠疫情可能二次暴发”，该信息使养猪户扩大规模的意愿降低了13.4%；2021年，处理组的农户被告知“新冠疫苗已经投入使用，但新冠疫情可能仍会持续”，该信息使养猪户扩大规模的意愿降低了4.4%。其次，相较于生猪生产没有受到新冠疫情真实影响的养猪户户，新冠疫情信息对真实受到新冠疫情影响养猪户户的生产意愿的负面影响更大。最后，本文使用跟踪数据证明了养猪户的生产意愿可以预测后续的实际生产行为。

Abstract:

This paper examines the impacts of information about COVID-19 on pig farmers’ production willingness by using endorsement experiments and follow-up surveys conducted in 2020 and 2021 in China. Our results show that, first, farmers were less willing to scale up production when they received information about COVID-19. The information in 2020 that the second wave of COVID-19 might occur without a vaccine reduced farmers’ willingness to scale up by 13.4%, while the information in 2021 that COVID-19 might continue to spread despite the introduction of vaccine reduced farmers’ willingness by 4.4%. Second, farmers whose production was affected by COVID-19 were considerably less willing to scale up, given the access to COVID-19 information. Third, farmers’ production willingness can predict their actual production behavior.

Key words: COVID-19 , randomized experiment , information treatment , production willingness
