笔者首次将对数平均迪氏指数分解法(LMDI)引入R&D与经济增长动态驱动关系的研究,构建GDP总量分解模型,把GDP变动总效应分为R&D活动效应、结构效应以及效率效应,并由此对1999年~2009年我国31个省市区GDP与R&D投入的关系进行了实证分析。结果表明,R&D活动效应对GDP变动总效应的贡献最大;R&D结构效应对GDP变动的正向影响较为稳定,但不够显著;R&D效率效应与GDP增长显著负相关。据此,我们给出了进一步优化我国R&D投入、实现经济内涵式增长的政策建议。
筆者首次將對數平均迪氏指數分解法(LMDI)引入R&D與經濟增長動態驅動關繫的研究,構建GDP總量分解模型,把GDP變動總效應分為R&D活動效應、結構效應以及效率效應,併由此對1999年~2009年我國31箇省市區GDP與R&D投入的關繫進行瞭實證分析。結果錶明,R&D活動效應對GDP變動總效應的貢獻最大;R&D結構效應對GDP變動的正嚮影響較為穩定,但不夠顯著;R&D效率效應與GDP增長顯著負相關。據此,我們給齣瞭進一步優化我國R&D投入、實現經濟內涵式增長的政策建議。

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.
