Global Demographic Structure and Korea's Productivity: Challenges and Opportunities

The Demographic Shock and the Productivity Imperative The global economy is undergoing a profound transformation driven by low birth rates and aging populations. While this demographic shift is a global phenomenon, South Korea is experiencing it at an unprecedented speed. This change is not merely a social issue but a fundamental economic shock that alters the core engines of growth: labor and capital. As the working-age population shrinks, the contribution of labor to economic growth inevitably turns negative. Consequently, sustaining economic growth depends entirely on productivity. The central challenge for policymakers is no longer just how to expand the workforce, but how to reconfigure the economy to produce more with fewer people through innovation and efficiency. This report analyzes the impact of demographic changes on Korea's productivity, drawing lessons from Japan’s experience and utilizing economic simulations. It explores how aging affects investment incentives and why “intangible assets”—such as technology, software, and organizational know-how—are critical for Korea's economic survival. Furthermore, it highlights how global financial conditions can act as a buffer for Korea's open economy.
