Abstract With the development of the digital economy, the potential of data elements and the fusion effect of different technologies have been greatly stimulated and released, providing a good material foundation and market development momentum for digital technology innovation. At the same time, as an emerging force to promote economic development, digital technology innovation is directly related to the high-quality development level of the digital economy. Both are derived from the needs of social practice, and centered on development and oriented towards development. It directly affects the operation of the innovation system,the process and speed of the construction of digital China if digital technology innovation and the development of digital economy are coordinated. However,at present, different regions in China rely on the original economic foundation and digital technology innovation to compete for key data element resources, which makes the development of digital economy more unbalanced. Therefore, it is of great significance to explore how to transform the comparative advantage of digital technology innovation into the competitive advantage of digital economy development for promoting the coordinated development of digital technology innovation and digital economy.#br#At present, most scholars focus on the research on the one-way impact of digital technology innovation or digital economic development. Few scholars systematically measure and deeply analyze the coupling coordination degree between digital technology innovation and digital economy development, and there is a lack of investigation on the coordination and interaction of the two at the regional level. This paper uses panel statistics of 30 provinces in China from 2015 to 2020. On the basis of constructing the evaluation index system of digital technology innovation and digital economy development, it adopts the data analysis methods such as the entropy value method, coupling coordination degree model and Moran index to analyze the regional characteristics and spatial correlation of coupling coordination degree of digital technology innovation and digital economy development, so as to explore if China's digital technology innovation and digital economy development match.#br#The results show that, first, according to the comprehensive scores of digital technology innovation and digital economy development, China's digital technology innovation and digital economy development have shown a good upward trend. Moreover, the distribution of digital economy comprehensive scores in the quartile table is slightly more balanced than that of digital technology innovation. However, the comprehensive scores of both are relatively low, and there is still a lot of room for growth in the future. Second, from the perspective of the overall characteristics of the coupling coordination degree between digital technology innovation and digital economy development, China's overall coupling coordination degree has shown a fluctuating rise, but it is still on the verge of imbalance. This is mainly due to the fact that China's digital technology innovation lags behind the development of the digital economy, so it is essential to focus on improving the digital technology innovation to drive the improvement of the coupling coordinated development of the two. The coupling coordination degree between digital technology innovation and digital economy development in the four regions is quite different. By 2020, the level of coupling coordination in the eastern region had been developed to a barely coordinated stage, the central region had been on the verge of imbalance, and the northeast and western regions had been slightly out of balance. Third, the spatial correlation analysis of the coupling coordination degree of digital technology innovation and digital economy development shows that there is a significant spatial autocorrelation between digital technology innovation and digital economy development in China, and it shows a serious imbalance in geographic spatial distribution. This imbalance is manifested in that the agglomeration areas with high coupling coordination degree are mainly located in the eastern coastal areas, while the northeast and west areas form low-value agglomeration areas.#br#This paper enriches the existing research on the interaction of technological innovation and economic development, and expands the application scope of coupling coordination theory in digital economics. In addition, it has reference value for guiding similar regions to give full play to their digital technology innovation capabilities and improve the coupling coordination degree between digital technology innovation and digital economy development. It also provides decision-making reference for the implementation of China's digital development strategy .#br#
