The coupled and coordinated development of digitization and greening in China is an important engine for realizing economic growth and the goal of "double carbon". This paper constructs an evaluation index system of digitization and greening, measures the level of digitization and greening in China from 2012 to 2021 with the help of the entropy method, and then adopts the coupling coordination model to measure the level of coupled and coordinated development of digitization and greening in the whole country, and finally examines the dynamics of the distribution of the coupled and coordinated development of digitization and greening in China and the four major sectors with the help of the Kernel Density Estimation (KDE) method. The study finds that: China’s digitization and greening levels have both increased to a certain extent; the eastern region has the highest level of coupling coordination, the fastest average annual growth rate, and significant differences with the central, western and northeastern parts of the country; the overall spatial distribution takes on the characteristics of "high in the east and low in the northeast"; It is also found that the development level of digitalization and greening coupling in the country as a whole, in the east and west regions, shows a multi-polar pattern during the sample period, while the level in central and northeastern regions shows unipolar characteristics.
