This paper treats R&D investment as capital rather than intermediate inputs, redefining the concept of the contribution rate of scientific and technological progress and undertaking its estimation.Using data at the national and provincial levels from between 1990 and 2017, it is found that:(1) while economic growth in China mainly comes from capital investment and scientific and technological progress, the annual contribution rate of scientific and technological progress to national economic growth has reached 48.97%, making it one of the most important sources of power for China's economic growth; (2) since the global financial crisis of 2008, the contribution rate of R&D capital deepening to China's economic growth has increased considerably, but the rapid decline in the total factor productivity (TFP) is the prime reason for the lower contribution rate of scientific and technological progress and the economic recession of recent years; and (3) since 2013, TFP in most of the eastern provinces, such as Shanghai, Zhejiang and Jiangsu, has bottomed out and then started to pick up again, however, other areas, such as Liaoning, Xinjiang and Shanxi, which have heavy chemical and resource-intensive industries, have experienced a severe decline, with some even reaching negative values.Therefore, accelerating the reversal of the TFP decline in heavy chemical and resource-intensive industrial areas is crucial to improving the contribution rate of China's scientific and technological progress and thus curbing economic growth decline.
