Dynamic assessment of the carbon-neutral process based on FDA method

Abstract

In this paper, the carbon-neutral process is constructed to measure the development level of a low-carbon economy in 30 provinces of China. The entropy weight method is used to measure the carbon neutralization level. The Functional Data Analysis and various curves are used to investigate potential dynamic changes. Finally, the heterogeneity analysis is carried out on the sample provinces. We find: (1) The carbon-neutral process’s performance of provinces is significantly different in China, the top three are: Guangzhou (0.6556), Shanghai (0.5559), Jiangsu (0.5095), and the last three are: Xinjiang (0.1583), Gansu (0.1475), Guizhou (0.1453); (2) The carbon-neutral process’s performance in China shows an obvious upward trend and the growth rate has usually been positive; (3) Through heterogeneity analysis, the performance of carbon neutralization process is different in the five regions. But all regions are currently in an upswing or recovery phase. These findings are significant for China to achieve’Carbon Peak in 2030, Carbon Neutrality in 2060’ as scheduled.
