Abstract: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.
