The wide application of digital technology is the only way to promote high-quality economic development. Based on the theoretical analysis of the integration of digital, energy, economy and environment, the integration level of four fields in 30 provinces (due to the lack of data, the statistical data mentioned here do not include the Tibet Autonomous Region, the Hong Kong Special Administrative Region, the Macao Special Administrative Region and Taiwan Province) in China from 2012 to 2021 was estimated by the modified coupling coordination degree model, and the spatial autocorrelation model was used to study their spatial distribution characteristics. The results show that the coupling levels of national digital, energy, economy and environment show a good upward trend during the observation period, and finally are in a basic coordination state. The pace of integration and development in the eastern and western regions is relatively synchronous, but the level of coordination among provinces is obvious, and some regions have obvious spatial agglomeration effect.
