Notes: The dependent variable for all columns is the growth rate of county-level gross domestic product per capita. Standard errors are clustered in province-by-years and counties. Temperature is measured in degrees Celsius and precipitation is measured in millimeters. *p < 0.1, **p < 0.05, and ***p < 0.01.

aIn column 5, counties with an average temperature above 20°C are excluded.

bIn column 6, the hottest year 2012 is excluded.
