Understanding the Decline of Innovation in Aging Firms

A recent study conducted by researchers from Waseda University and the University of Wisconsin sheds light on a critical issue faced by many corporations: the decline in innovation as companies age. Traditionally, it is believed that aging firms tend to become rigid, leading to decreased performance and creative outputs. However, this research dives deeper, measuring the extent of that rigidity and its relationship with research and development (R&D) portfolios.

Key Findings

The research proposes that as companies age, they face challenges in reorganizing management resources, which result in their technological portfolios becoming increasingly inflexible. Using a new methodology, the researchers, led by Professor Hiroshi Shimizu from Waseda University, utilized cosine similarity to assess the proximity of a company's current R&D activities to its historical patents. In essence, they were measuring how closely aligned a company's current focus was to its past projects.

The findings indicate that while the quantity of patents produced increases as portfolios become more rigid, the quality of these inventions tends to decline. This phenomenon suggests that a persistent focus on the same technology areas can reduce the overall innovation effectiveness of aging companies. Essentially, it emphasizes that enhancing R&D flexibility should become a central strategy for older firms aiming to revitalize their innovation output.

Contextual Background

Historically, it has been observed that with aging comes decreased profitability and fewer innovations. This has led the business community to advocate for startups and new ventures, often seen as engines of innovation. However, the question of how rigidity, particularly the measurement of its degree, affects innovation remained largely unexplored until this research.

New Methodologies and Concepts

The innovative approach of utilizing cosine similarity—not just to measure technical similarity between different firms but also to quantify the similarity of a firm’s current R&D focus with its past efforts—has opened a new avenue for understanding corporate innovation dynamics. This research could significantly impact how businesses evaluate their R&D strategies going forward.

Broader Implications for Society

With Japan's corporate landscape exhibiting a slower rate of renewal compared to the U.S., the implications of this research are particularly relevant. The results emphasize the importance of being able to reconfigure management resources flexibly as a strategic necessity for aging businesses. Additionally, fostering new companies and facilitating the exit of inefficacious ones could prove vital for overall economic health.

Future Directions

While this study has made considerable progress in understanding the effects of aging on companies, the challenge lies ahead in identifying characteristics or practices that prevent organizational rigidity as firms age. Interestingly, rigidity isn’t solely detrimental; concentrated research and development efforts in a specific domain can yield significant advancements, particularly in technologies classified as general-purpose technologies.

Insights from Researchers

The research team's observations reveal that the issues surrounding corporate aging are notably pronounced in Japan. Their analysis showed that Japanese companies, on average, displayed higher rigidity than their American counterparts. For instance, a Japanese company in its 30s exhibited rigidity levels comparable to a 90-year-old American company. This research highlights the crucial role large corporations can play in fostering innovation, emphasizing the need to discover how they can avoid rigidity to continue generating valuable inventions.

Conclusion

The study, titled _Age of U.S. Public Firms, Proximity to the Past Patent Portfolio, and Innovation_, published online in the _Journal of Evolutionary Economics_ on April 26, 2025, serves as a crucial step towards addressing how aging firms can adapt their strategies to enhance innovation. As the business landscape continuously evolves, adapting to the challenges posed by aging will be essential for maintaining healthy levels of creativity and progress.
