summary We study the link between temperature and economic development at the sub-national level, employing cross-sectional data from two distinct sources. In contrast to much of the existing cross-country literature on the temperature–income relationship, our setting allows for the inclusion of country-fixed effects. Once we account for country-fixed effects, we do not find a statistically robust relationship between regional temperature and three different measures of regional economic development (per capita GDP, nightlights and gross cell production). We also test whether temperature is non-linearly related to regional income (with hotter regions being potentially particularly prone to adverse effects of temperature on income) but find no systematic evidence in favour of such a relationship. Finally, we examine whether the effect of temperature on economic development is especially pronounced in poorer regions (e.g., due to weaker adaptation). Again, we find no statistically robust link.

区域温度和区域收入之间的联系：具有地方数据的计量经济学证据

总结 我们利用来自两个不同来源的横截面数据研究了地方层面的温度与经济发展之间的联系。与许多现有的关于温度-收入关系的跨国文献相比，我们的设置允许包含国家固定效应。一旦我们考虑到国家固定效应，我们发现区域温度与区域经济发展的三种不同衡量指标（人均 GDP、夜灯和电池总产量）之间没有统计学上的稳健关系。我们还测试了温度是否与地区收入呈非线性关系（较热的地区可能特别容易受到温度对收入的不利影响），但没有发现支持这种关系的系统证据。最后，我们研究了温度对经济发展的影响是否在较贫困地区特别明显（例如，由于较弱的适应）。同样，我们发现没有统计上稳健的联系。
