This study aims to examine the effect of carbon dioxide emission and air pollution on agricultural productivity while accounting for the effect of renewable energy use, ICT, technological innovation, environmental policy stringency, and democracy for Brazil, Russia, India, China, and South Africa (BRICS) during the period 1990-2019. Several econometric procedures including mean group estimates are employed. The result suggests that both carbon dioxide emission and air pollution negatively affect the productivity of the agricultural sector. The effects of renewable energy, ICT, technological innovation, and democracy are found to be increasing agricultural productivity. Environmental policy stringency coefficient confirms the porter hypothesis. The result from the causality test suggests that bidirectional causality exists between CO, PM, renewable energy, technological innovation, ICT, and agricultural productivity. Finally, the study provides several policy suggestions for the governments of the BRICS economies in order to increase agricultural productivity while tackling the environmental vulnerability.
本研究旨在考察二氧化碳排放和空气污染对农业生产力的影响，同时考虑到可再生能源利用、信息通信技术、技术创新、环境政策力度和民主因素对巴西、俄罗斯、印度、中国和南非（BRICS）在 1990-2019 年期间的影响。本文采用了多种计量经济学方法，包括均值组估计。结果表明，二氧化碳排放和空气污染都对农业部门的生产力产生负面影响。可再生能源、信息通信技术、技术创新和民主的影响被发现可以提高农业生产力。环境政策力度系数证实了波特假说。因果关系检验的结果表明，CO、PM、可再生能源、技术创新、信息通信技术和农业生产力之间存在双向因果关系。最后，本研究为 BRICS 经济体的政府提供了一些政策建议，以在应对环境脆弱性的同时提高农业生产力。
