Sectoral patterns of technological activity and export market share dynamics
研究了OECD国家制造业中部门多样性对创新过程及技术与世界市场份额关系的影响，发现技术变量显著且R&D强度分类有助于理解部门多样性在竞争中的作用。
This paper focuses on a selected number of OECD countries and manufacturing sectors and shows the importance of sectoral diversity in the innovative process and in the relation between technology and world market share dynamics. The econometric exercise confirms the importance of technological variables in the relation with world market shares in two ways: first they are, in general, statistically significant, second the taxonomy of technological classes in terms of R&D intensity seems to be meaningful in disentangling the role played by sectoral diversity in the relation between embodied and disembodied investment and competitiveness. Sectoral diversity emerges in the statistical significance of the coefficients and in the time lag structure. Moreover, the values of estimated R&D parameters are correlated with the sectoral R&D intensity. Copyright 2003, Oxford University Press.
