Abstract New infrastructure construction shoulders the multiple tasks of stabilizing growth, adjusting structure, benefiting people's livelihood and promoting innovation, and plays an important role in China's economic development. Under the continuous impact of the COVID-19 epidemic, new infrastructure construction provides a strong impetus for the national technological innovation and high-quality economic development. The new infrastructure, embedded in the process of modernization of the national governance system, is mutually supportive and interdependent with the technological innovation system. The current literatures mainly focus on the one-way transmission mechanism of new infrastructure construction to technological innovation, but seldom pay attention to the coupling mechanism between the two systems. Therefore, the purpose of this study is to reveal the synergistic development relationship between new infrastructure construction and technological innovation by empirical methods.#br#The new infrastructurecon struction and technological innovation are closely related and mutually supportive.On the basis of the coupling mechanism of the two systems, a comprehensive evaluation index system is constructed. The new infrastructure construction system includes 15 indicators in three dimensions: information infrastructure, integrated infrastructure and innovative infrastructure. Technological innovation system covers 16 indicators in four dimensions: innovation environment, innovation input, innovation output and innovation performance. The study analyzes the evolution characteristics of the spatial-temporal pattern of the coupling and coordination of the two systems in China's 31 provinces, municipalities and autonomous regions in mainland China(Hong Kong, Macao and Taiwan excluded) from 2013 to 2020, using the entropy method, coupling coordination evaluation model, exploratory spatial data analysis (ESDA) and standard deviation ellipse model.#br#The results show that firstly both the comprehensive index of new infrastructure investment level and technological innovation capability have been increasing year by year, showing a gradient decreasing pattern from east to west. Secondly the degree of coupling and coordination between new infrastructure investment level and technological innovation capability in various provinces has risen, but a good coupling development situation has not yet been formed, among which more than half of the provinces and cities are of coupling imbalance type. Thirdly the degree of coupling and coordination between new infrastructure investment level and technological innovation capability has a remarkable positive spatial correlation, which is manifested as the high-value agglomeration area in the east and the low-value agglomeration area in the west. Lastly the spatial distribution of coupling coordination degree is unbalanced. From 2013 to 2020, the standard deviation ellipse of the national coupling coordination degree was distributed from northeast to southwest, and the center of gravity moved to the southeast as a whole, with significant spatial agglomeration characteristics. #br#This paper analyzes the coupling mechanism between new infrastructure investment level and technological innovation capability from both theoretical and empirical aspects, and puts forward some suggestions for reference. First, the government should formulate differentiated policies to promote the development of new infrastructure construction. Second, it is critical to enhance the regional innovation level, as a way to strengthen the role of technological innovation to support the new infrastructure. Third, governments at different levels should make overall plans and optimize the coupling and coordination quality between the new infrastructure investment level and technological innovation capability. Finally, it is urgent to consider how to improve the coupling and coordination between the new infrastructure investment level and technological innovation capability from a multi-scale perspective. The eastern region should continue to promote the circulation of resources, technology, talents and other elements, and give full play to its radiation and driving effect on surrounding provinces and cities. For the central region with the second highest degree of coupling and coordination, it should strive to improve the independent innovation ability to support the development of new infrastructure. For the northeast region with a low degree of coupling and coordination, it should strengthen the innovation of system and mechanism, adjust the industrial structure and give consideration to innovation driven and regional coordinated development. For the western region with the lowest coupling coordination, it is necessary to give consideration to the coordinated development of traditional infrastructure and new infrastructure, seize the construction opportunities of the "the Belt and Road" to strengthen regional innovation and exchange, and steadily promote regional sustainable development.#br#
