英文文献作者：Fulvio Castellaci
英文文献摘要：
The paper investigates cross-country differences in technology in a large sample of developed and developing economies over the 1990s. The empirical analysis indicates the existence of three technology clubs with markedly different levels of technological development: advanced, followers and marginalized countries. The technology clubs also differ with respect to their dynamics over the 1990s. While the club of followers is characterized by a process of gradual convergence towards the technological frontier, the group of marginalized has experienced an increase in its gap in terms of innovative capabilities.
