Abstract:    With the deepening of open innovation, global technology cooperation methods have become diversified, resource flow patterns have become networked, and the scientific and technological innovation capabilities of countries have gradually increased. However, there is still a large gap in the innovation level of high-tech industries among various regions of our country, and most regions are still in the state of "technical catch-up". At the same time, the "island phenomenon" in our country′s scientific and technological innovation have interrupted the knowledge transmission chain between various innovation subjects, which in turn led to inadequate capabilities in various regions to acquire, diffuse and apply knowledge. Therefore, it has become an important theoretical issue that determines the rapid development of the region to clarify how to break through the obstacles to innovation and cooperation in each region, and solve the problems of insufficient regional development resources and scattered information resources. Based on the provincial panel data of China from 2013 to 2018, this paper constructs a model to discuss the mechanism of regional innovation networks and technology flows of high-tech enterprises on regional innovation capability. Furthermore, this study analyzes the impact of high-tech enterprise technology flow on regional innovation development in regions with different innovation network levels, and then uses a threshold model to analyze the changing trend of technology output and technology absorption of high-tech enterprises in the technology market with the improvement of the level of regional innovation network. The empirical results show that:Firstly, regional innovation networks, high-tech enterprise′s technology output and technology absorption contribute to the improvement of regional innovation capabilities, but their mechanisms and intensities of the impact are different. The innovation network achieves the improvement of regional innovation capabilities by making up for the shortcomings of resource shortages among various innovation subjects. The strength is the strongest. The technology absorption of high-tech enterprises relies on the effects of "endogenous growth of technology" and "optimized resource allocation" to promote the improvement of regional innovation capabilities, with the intensity followed. The technology output of high-tech enterprises relies on the effects of "market competition" and "optimized resource allocation" to enhance regional innovation capabilities, with the weakest intensity. Secondly, compared with regions having underdeveloped innovation networks, high-tech enterprises in regions with developed innovation networks have positive self-reinforcing mechanisms for technological innovation, but the power of innovation networks is slightly weaker. In areas with developed innovation networks, high-tech enterprises need to transfer valuable technologies to activate positive feedback that high-tech enterprises enhance regional innovation capabilities, and then maintain the competitive advantages they have obtained. In regions with underdeveloped innovation networks, innovative members promote the improvement of innovation capabilities by building a collaborative network structure. In regions with developed innovation networks, innovative members rely on joining the multi-interactive cooperative network to maintain innovation advantages. Thirdly, whether the innovation network is developed or underdeveloped, the impact of technology absorption on regional innovation capabilities is greater than technology output. Technology absorption of high-tech enterprises actively seeks out their own technological deficiencies, precisely introduces and absorbs heterogeneous technologies, finally breaks through the dilemma of insufficient innovation. The technology output of high-tech enterprises is usually based on the economic benefits of technology applications to passively select technologies with profitable prospects, and tend to repeatedly provide technologies that they are good at to the technology market. Therefore, the passive innovation of technology output of high-tech enterprises plays a weaker role in promoting regional innovation capabilities.Finally, with the evolution of the level of regional innovation network, the technology flow of high-tech enterprises has an increasingly weak impact on regional innovation capability. Compared with the high cost of technology transaction, the closely interactive network relationship makes each innovation subject choose to carry out adaptive cooperative innovation with other innovation subjects based on their interest demands, obtain complementary innovation resources, and solve the innovation gap caused by information stickiness, which has the absolute advantage of low cost.
