This analysis shows there are regimeswitching. With the R&D intensity increasing, the effect of R&D investment on economic growth is stronger and stronger. With the proportion of industry in GDP increasing, the effect becomes from nonsignificant to significant. However, with the proportion of the third industry in GDP increasing, the effect becomes from significant to nonsignificant.
