Abstract:Since the new century, global science and technology innovation has been more intensive and active than ever before. The new round of technological and industrial changes has led to the reorganization of the global innovation map. Meanwhile, China's overall strength in science and technology is also moving towards a new stage of systematic improvement, and the strategic goal of fully building a world power in science and technology in 2050 is proposed. In the process of national innovation development, how to evaluate the effectiveness of a country's efforts needs to be judged by a set of perfect indicator systems, which means that a set of evaluation systems can measure the national science and technology innovation capacity in a scientific and fair manner is particularly important. However, there are some differences in the structure, focus and evaluation methods of the existing evaluation systems, which make the real level of science and technology innovation capacity of countries around the world still to be verified. Based on this, it is particularly important to sort out the existing typical national innovation capacity evaluation systems, compare the similarities and differences of the systems from both longitudinal and horizontal perspectives, summarize their characteristics, and propose the main insights on the measurement of science and technology innovation capacity. This move can accurately observe China's level of scientific and technological innovation and international status, and has important theoretical and practical significance for accelerating China's construction of a world power in science and technology.
