In the National Innovation System (NIS), knowledge is produced and accumulated through interactive innovation processes that are embedded in a national context, which in turn may help determine innovation. This paper investigates how product and process innovations in the European food and drink industry are affected by: (i) NIS structure; (ii) NIS output in terms of scientific publications and the supply of graduates; (iii) NIS cohesion and coordination; (iv) NIS scientific impact and specialisation. The main source of data on innovation by firms is the EU‐EFIGE/Bruegel‐UniCredit dataset. This is supplemented by information from the International Handbook of Universities, Eurostat and a bibliometric analysis of academic research output. Our results suggest that large research institutions in the public sector may well be detrimental to interaction between university and industry and to process innovation. The indicators used for public research assessment are not necessarily the most appropriate proxies of local knowledge spillovers. 相似文献

We develop a model explaining the consolidation patterns in the agricultural biotechnology industry. Among different consolidation and cooperation mechanisms, we consider collaborative and licensing agreements, joint ventures, acquisitions, and exchanges of ownership and spin-offs. The key results derive from the benefits of coordinated actions, distinction between transferable and nontransferable payoffs, the substitutability, complementarity, and the importance of the managers' noncontractible investments, and access and expansion of markets. Results from the model are used to examine the cooperation and consolidation activities for four major players in the agricultural biotechnology industry, DuPont , Dow Chemical , Monsanto , and Novartis . 相似文献

本文以辽宁省为研究单元,运用格兰杰(Granger)因果检验分析辽宁省高新技术产业与经济发展的关系,结果表明两者存在双向因果关系;同时使用柯布—道格拉斯(C-D)生产函数表明辽宁省高新技术产业的发展对全省工业经济有着良好的拉动作用,但是对整个经济结构的转变贡献率还较低,所以应进一步加强辽宁省高新技术产业的发展,加速实现将经济增长从劳动和资本密集型的传统工业增长方式向技术密集型的高新技术产业增长方式转变。 相似文献
