This study employs Artificial Intelligence to develop experimental future scenarios for North Korean regional development. Focusing on government-proposed areas of inter-Korean economic cooperation - energy, transportation, and agriculture - the research analyzes current challenges including power supply instability, logistics inefficiency, and low agricultural productivity. The study proposes solutions utilizing Fourth Industrial Revolution technologies, such as smart grid systems with Northeast Asian connections, autonomous logistics networks, and advanced agricultural technologies. The use of Large Language Models (LLMs), with their extensive data processing capabilities, enabled generation of creative future scenarios beyond conventional research methods. Policy simulations using virtual personas demonstrated the potential for developing tailored policies considering North Korea’s characteristics. This research holds methodological significance through its experimental use of LLMs and offers valuable reference material for future inter-Korean economic cooperation policies by exploring new possibilities for North Korean regional development.
