摘      要：This study investigated the adverse effect of surface ozone on the maize yield using a unique panel from 880 counties in *** identify the impact of elevated surface ozone concentrations,we constructed an econometric model by controlling the impact of climate variables and related economic *** study also considered the potential spatial correlation in the measurement of the impact of surface ozone on maize *** confirmed that the increase of ozone concentration decreased the maize ***,maize was found to be the most sensitive to ozone at the end of the second month of the growing *** average annual loss of maize caused by ozone pollution is about 4.234 million tons in 2013–2015,accounting for 1.9%of the average output.
