Innovation and economic performance in services: a firm-level analysis
利用企业层面数据，研究了服务业中创新与经济绩效的双向关系，发现过去的经济绩效促进创新，而创新（尤其是ICT投资）又推动增长和生产率，形成自我强化机制。
This paper explores the two-way relationship between innovation and economic performance in services using a longitudinal firm-level dataset which matches data from the second Community Innovation Survey, CIS II (1993--95), against a set of economic variables provided by the System of Enterprise Accounts (1993--98). The results presented show that innovation is positively affected by past economic performance and that innovation activities (especially investments in ICTs) have a positive impact on both growth and productivity. Furthermore, productivity and innovation act as a self-reinforcing mechanism, which further boosts economic performance. These findings provide empirical support for the endogenous nature of innovation in services and the presence in this sector of competition models and selection mechanisms based on innovation.
