本文基于生态经济学理论,从生态福利绩效视角构建了碳排放福利绩效指标及其影响因素面板计量模型,在此基础上对G20国家1990-2018年的碳排放福利绩效进行了国别比较和影响因素实证分析。主要研究结论为：①2018年英国、法国、阿根廷、巴西、德国的碳排放福利绩效较高,1990-2018年间英国、土耳其、德国、意大利以及巴西等国的碳排放福利绩效增速较快；中国2018年碳排放福利绩效和历年均值在G20国家中都排名靠后,且增速较慢,表明中国低碳竞争力缺乏静态和动态优势。②城市化率、可再生能源在能源消费总量中的占比、外贸依存度以及服务业增加值在GDP中的占比对碳排放福利绩效有正向影响；政府规模与碳排放福利绩效呈倒U型曲线关系,表明政府规模存在治理门槛。最后,根据以上结论提出中国未来可持续发展的针对性政策建议。

Based on the theory of ecological economics, this paper constructs an indicator of wellbeing performance of carbon emissions and its influencing factors panel measurement model. And then, conduct empirical analysis on wellbeing performance of carbon emissions and its influencing factors of G20 from 1990-2018. The main research conclusions are as follows: ①In 2018, the UK, France, Argentina, Brazil, and Germany had higher wellbeing performance of carbon emissions, and from 1990 to 2018, wellbeing performance of carbon emissions of the UK, Turkey, Germany, Italy, and Brazil increased rapidly; Both wellbeing performance of carbon emissions in 2018 and the average value over the years of China ranked low among the G20 countries, and the growth rate was slow, indicating that China"s low-carbon competitiveness lacks static and dynamic advantages. ②Urbanization rate, the proportion of renewable energy in energy consumption, foreign trade dependence, and the proportion of service industry added value in GDP have a positive impact on wellbeing performance of carbon emissions; The relationship between government size and wellbeing performance of carbon emissions are inversely U type curve, indicating that there is a governance threshold for the scale of government. Finally, based on the above conclusions, puts forward targeted policy recommendations for China"s future sustainable development.
