This paper investigates the effects of temperature on agricultural TFP growth rates during the period 1992–2015. We argue that higher temperatures impede TFP growth, particularly in low-income countries (LICs) using less imported inputs. Our estimates imply that a 1°C rise in annual average temperatures reduces TFP growth rates by 5.2 percentage points in the LICs in question. However, LICs using greater amounts of imported inputs are less affected by temperatures, suggesting a new source of gains from imported inputs mitigating the adverse effects of rising temperatures.

为减缓气候变化进口投入：以农业生产力为例

本文研究了 1992-2015 年期间温度对农业 TFP 增长率的影响。我们认为，较高的温度会阻碍 TFP 增长，特别是在使用较少进口投入的低收入国家 (LIC)。我们的估计意味着年平均气温上升 1°C 会使相关低收入国家的 TFP 增长率降低 5.2 个百分点。然而，使用大量进口投入品的低收入国家受温度影响较小，这表明进口投入品的新收益来源可以减轻气温上升的不利影响。
