Frank van der Wouden an assistant professor of Economic Geography and Innovation Studies at The University of Hong Kong. He is a scholar of innovation whose research explores how geography shapes innovation management, technology development, and regional economic growth. His work highlights the role of collaboration in driving knowledge creation across teams, firms, and cities. By combining big data with advanced quantitative and machine learning methods, he provides new insights into the complex dynamics of innovation in today’s economy.

He earned his PhD at the University of California, Los Angeles, and completed a postdoctoral fellowship at the Kellogg School of Management, Northwestern University. Earlier, he received his BSc and MSc degrees from Utrecht University in the Netherlands.

His research has appeared in leading journals such as Research Policy,Industry & Innovation,Industrial and Corporate Change,World Development,Economics of Innovation and New Technology,Regional Studies,and Papers in Regional Science, among others.

讲座内容摘要

The clustering of economic activity is often seen as a cornerstone of competitiveness. Yet, we still know surprisingly little about how technological activities are clustered within cities—and how such neighborhood-level concentrations shape the broader process of technological diversification. Much of the existing literature treats cities as homogenous units, overlooking their internal heterogeneity and neighborhood dynamics.

In this talk, I present a new framework for identifying technology clusters at the neighborhood level across 260 Chinese cities, drawing on a dataset of 16 million geo-coded patents from 2003–2018. I then examine how these local clusters are connected to the rate, direction,and complexityof technological diversification at the city level, measured as the emergence of new revealed comparative advantages in patent portfolios.

The results show that neighborhood clusters (1) accelerate the overall pace of diversification, (2) channel it toward technologies related to existing specializations, and (3) foster more complex forms of diversification. Taken together, the findings suggest that zooming in on the micro-dynamics of clustering offers a richer perspective on the benefits of agglomeration. I conclude by discussing the implications for both policymakers and business leaders, who may need to rethink how they design innovation and development strategies in an increasingly knowledge-driven economy.
