Abstract: Regarding the R&D intensity as an indicator of indigenous R&D efforts, the technology trade as an indicator of international technology flows, G7 countries as the sample, this paper discussed the evolution path of portfolio pattern on indigenous R&D efforts and international technology flows and the effect of the portfolio to the national innovation and economic development. The results showed that: the evolution path of portfolio pattern in G7 countries was external technology drive pattern- internal and external drive pattern - the internal drive and external pull pattern - external technical pull pattern - external technology drive pattern; the effects of indigenous R&D efforts and international technology flows to the national innovation and economic development are significant, although the role of indigenous R&D efforts was more prominent. Based on the experiences of G7, China should strengthen the management of R&D funding when increasing the R&D intensity rapidly, then shift from external technology drive pattern to internal and external drive pattern.
