摘　　要：在探究NO_(2)浓度和经济发展相关关系的基础上,以NO_(2)浓度为经济的代理变量,构建新冠肺炎疫情影响测度指数,研究2020年新冠肺炎疫情下中国的经济复苏。研究结果表明:NO_(2)高浓度地区及疫情重灾区受新冠肺炎疫情影响较大;新冠肺炎疫情背景下的中国经济发展先后经历了三个阶段,即深V型波动期、震荡型恢复期和稳健复苏期。Based on the correlated relationship between NO_(2) concentration and economic development,this paper set NO_(2) concentration as a proxy variable of economy,and constructed COVID-19 impact measurement index,then explored the economic recovery after the outbreak of COVID-19 in 2020.The results showed that,the areas with higher NO_(2) concentration,as well as the hard-hit areas,all have been significantly affected by COVID-19.In general,after the outbreak of COVID-19,China's economic development has experienced three stages,deep V-shaped fluctuation period,shocked recovery period and steady recovery period.
