This article uses the coupling coordination model and relative development model to empirically analyze the coupling coordination status and relative development level of digital economy and technological in-novation.Research has found that:(1)From the perspective of temporal development,the digital economy de-velopment index and technological innovation development index in the Yangtze River Delta from 2013 to 2020 showed a steady upward trend,and the coupling coordination level showed an evolution pattern from low to moderate and then to high,achieving a transition from lagging digital economy development to synchronous de-velopment.(2)From the perspective of spatial development,from 2018 to 2020,the three provinces and one city gradually entered a highly coordinated stage.After 2016,the relative development status of the digital economy and technological innovation in the three provinces and one city varied significantly,and the interaction of dif-ferent relative development states had an impact on the relative development level of the two systems in the Yangtze River Delta.
