Abstract The authors introduced for the first time the Log-Mean Divisia Index Method (LMDI) to the the study of the driven relationship between R&D input and economic growth, constructed a decomposition model of total GDP variation, divided the total GDP variation effect into R&D activity effect, structure effect and efficiency effect and made an empirical research into the relationship between GDP and R&D input in 31 provinces and cities from 1999 to 2009. The results show that R&D activity effect makes the primary contribution to the total effect of GDP variation; the positive effect of R&D structure effect on GDP variation is stable but not obvious; the R&D efficiency effect is obviously negatively related to GDP growth. On the basis of this, the authors made some suggestions about optimizing the GDP input and realizing the substantial economic growth of our country.
