The development of China’s digital economy plays a crucial role in promoting high-quality economic development, while also providing impetus for the development of the digital economy. Jiangsu Province is a major province in economic development, so studying the coupling and coordination relationship between the digital economy and high-quality economic development is particularly important for Jiangsu Province. This article selects time series data from Jiangsu Province from 2007 to 2021, constructs an evaluation index system, measures the index of digital economy development and high-quality economic development, and analyzes the degree of coupling and coordination between the two. Based on empirical results, relevant countermeasures and suggestions are proposed to empower high-quality economic development in Jiangsu Province from the aspects of digital infrastructure construction, industrial digitization, and technological innovation capabilities.
