Abstract The Chinese government highlights high-quality development in building a modern socialist country in an all-round way, but the current issue of uneven and uncoordinated regional development is prominent. How to promote the overall high-quality development of the economy has become a common concern of the government and academia. At present, the improvement of total factor productivity has become a driving force for high-quality economic development. As the carrier of innovation activities, innovation infrastructure is the basic support for the improvement of total factor productivity and provides a material guarantee for the complete link of the innovation chain. Against the backdrop of China's unbalanced regional economic high-quality development, it is of great practical significance to analyze the impact of innovation infrastructure synergy on high-quality development, and find the measures for promoting high-quality development and narrowing the regional gap through collaborative agglomeration of innovative infrastructure in practice. #br# Most recent studies have focused on the impact of a single dimension of innovation infrastructure on high-quality development, and paid insufficient attention to the synergy effect. This study centers around innovation infrastructure synergies. Since innovative infrastructure has spatial effects, and in order to analyze the spatial spillover effects of innovative infrastructure on high-quality economic development, this study takes the panel data of 31 provinces in China from 2011 to 2020 to construct a spatial econometric model to empirically analyze the relationship between the innovation infrastructure synergy effect and high-quality development. It further constructs a spatial mediating effect model to test the mechanism of innovation infrastructure synergy affecting high-quality development. Meanwhile, this paper analyzes the heterogeneous impact of economic development stage and region using the spatial econometric model.#br# The result shows that except for R&D institutions of industrial enterprises, innovation infrastructure has significantly promoted the level of China's high-quality development, accounting for 22.23% of the overall increase in high-quality level from 2011 to 2020. Among them, the contribution shares of innovation infrastructure synergy, commercial service institutions, universities and research institutions, and agglomeration of manufacturing enterprises to high-quality development are 11.11%, 27.78%, 5.56%, and -22.22%, respectively. From the perspective of spatial effect decomposition, the improvement of China's high-quality economic development level mainly relies on spatial spillover (accounting for 93.63%), while the promotion of direct effect is relatively small (accounting for 6.37%). The innovation effect, knowledge spillover effect, structure effect, resource allocation effect and environment effect all play a mediating role in the synergistic impact of innovation infrastructure on high-quality economic development. Heterogeneity analysis shows that there are significant structural differences in the impact of innovation infrastructure and its synergistic effects on high-quality development in terms of economic development stages and regions.#br# The innovations in this paper are as follows. First, from a theoretical perspective, this paper makes a deep analysis of the mechanism of innovation infrastructure synergy effect affecting high-quality development, which provides a theoretical basis for leveraging the facility synergy effect to promote high-quality development; second,from an empirical perspective, it empirically tests the degree and heterogeneity of the impact of China's innovation infrastructure synergy on high-quality development, and measures the contribution of China's innovation infrastructure during the sample period.#br#From a practical perspective, this paper puts forward the following suggestions. (1) The government should make more efforts to promote innovative infrastructure synergy in the central and western regions, and effectively play the role of innovative infrastructure synergy in promoting high-quality development. (2) It is essential to optimize the layout of innovation infrastructure according to local conditions. The eastern region should strive to improve the professional level of commercial service institutions; the central region should strengthen the construction of commercial service institutions, encourage university-institution-industry cooperation, and guide industrial enterprise research and development institutions to increase research and development investment; the western region should actively attract innovative enterprises and promote the agglomeration of manufacturing enterprises. (3) Different regions should optimize transmission channels according to local conditions. The eastern region should accelerate the construction of integrated factor trading platforms, the central region should fully leverage the advantages of industrial structure to promote the optimization and upgrading of industrial structure, and the western region should focus on enhancing the construction of innovation infrastructure, and optimizing the innovation environment.#br#
