Interplay between regional and industrial aspects in the R&D–productivity link: evidence from Europe
研究了区域创新环境与产业类型如何共同影响企业研发投入对生产率的转化效果，发现高创新区域中高技术制造业受益最大，而低技术行业和服务业则不然。
Interplay between regional and industrial aspects in the R&D–productivity link: evidence from Europe. Regional Studies. The paper tests the effect of the interplay between regional and sectoral dimensions in the firm-level research and development (R&D)–productivity link. Using a longitudinal database of innovative publicly traded European companies between 1991 and 2008, the following main results arise. First, the elasticity of value added with respect to R&D is larger in regions characterized by a higher innovation performance (knowledge hubs versus industrial zones). Second, in knowledge hubs, industry affiliation mediates the gains from R&D: high-tech manufacturing firms profit more from R&D than low-tech ones. This evidence suggests that an innovative regional environment increases the capacity to translate R&D investments into productivity for European high-tech industries. This virtuous circle is not at work in services and in low-tech manufacturing industries.
