This study started with questioning the fact that in the assessmentof technology, which has taken place every two years since 2010, the technology gap in the most technologically advanced countries was evaluated as 4-5 years in each evaluation. To interrogate this question, regression estimation was performed using the Gompertz model based on time series data for technology level evaluation. As a result, it would take 17 years for high-speed rail vehicle technology to reach the level of 95 % of the country with the highest technology, and 72 years to reach the level of 100 %. Recognizing the technology gap is important in establishing a technology catchup strategy. A collaborative technology catchup strategy is the best strategy for moving to an original technology development stage while competing with large global leaders without much domestic market demand. This can occur regardless of where Korea is located in the technology catchup stage.

In the post-catchup era, the probability of technology risk are growing according to technology innovation activities with high uncertainty are increasing. Risk acceptance and management are appearing as a more important policy issue. This paper examines the technology risk as a political and social sight and the character of technological risk in the post-catchup era. In the post-catchup, new technology and policy are more undergone trial and err. In particular, we need new approach and policy countermeasures to cope with risky environment and overcome catchup legacy. Accordingly, Korea risk management is needed reshaping of risk management system, increment of risk communication, risk management according to technology type, precautionary approach, bounded trial and err strategy, knowledge accumulation and learning reinforcement.
