Abstract:High level technological innovation promotes high-quality development, which is the continuation, deepening, and upgrading of innovation driven development. It is a new positioning for China’s innovation driven development strategy in the new era and points out specific directions for a new round of high-quality development. The high level of technological innovation is reflected in specific aspects such as time level, layout level, adaptation level, and spatial level. The higher the level of technological innovation, the more long-term it focuses on, the longer the effectiveness of high-quality development; The higher the conversion rate of high-level technological innovation, the more realistic the feasibility of high-quality development; The stronger the high-level technological innovation strategy, the broader the prospects for high-quality development; The closer the integration of high-level technology and high-tech industries, the higher the efficiency of high-quality development. In response to the problems of insufficient support, imperfect mechanisms, underutilized potential, increasingly limited space for progress, and inconsistent actions in promoting high-quality development through high-level technological innovation in China, it is necessary to coordinate various departments and related fields, continuously improve the level of technological innovation, and enhance the long-term support for high-quality development; Improve the mechanism for releasing and evaluating high-level scientific and technological achievements, and promote the high-quality development of the knowledge system; Strengthening the strategy of high-level technological innovation and serving the construction of a new development pattern; Coordinate layout and actions, strengthen the systematic integration of high-level technology and high-quality development.
