New York University professor, Luohan Academic Committee member, and 2001 Nobel Prize Laureate in Economics, Michael Spence, gives a situational review with respect to the changes and opportunities brought about by digital technology. The unprecedented challenge, as he remarks, is the trade-offs between national security agenda and global digital economy which requires further cooperation and openness. International agreements or treaties might provide a solution. Spence also strengthens the role of a more balanced and multi-dimensional view to better use digital technology, particularly when digital welfare can be hardly captured by the standard national economic measures. With such conceptual transformation, the future digital development should be more boundless, interactive and sustainable.
