Abstract:In order to promote China's high-tech industry to give full play to its leading and supporting role in the development of high-quality economy, this paper deeply analyzes the influence of government financial support on the development of high-tech industry and its influence mechanism. Based on the relevant panel data of the 2009-in 30 provinces of China in 2020, a regression analysis model with the ability of enterprise technology acquisition as an intermediary variable is constructed, and the intrinsic relationship between financial support and the development of high-tech industry is empirically tested. The results show that financial support is an important driving factor for the development of high-tech industry, but there is regional heterogeneity in the impact on the development of high-tech industry. Only in the eastern region, there is a high promotion effect due to location advantages, and the ability of enterprise technology acquisition plays a part of the intermediary role in financial support and the development of high-tech industry. Therefore, some countermeasures and suggestions are put forward, such as increasing financial support to the central and western regions, coordinating the coordinated development of regional high-tech industries and paying attention to the improvement of technological innovation ability, so as to provide ideas for supporting and promoting the development of China's high-tech industries.
