Bio:
Philipp Boeing is an Associate Professor at Goethe University Frankfurt and a Senior Researcher at ZEW – Leibniz Centre for European Economic Research in Mannheim, Germany. His research investigates the role of innovation incentives and the impact of innovation on firm performance and economic growth. His work combines unique micro data, econometric analysis, and recent empirical methods, with a particular interest in policy evaluation, patent indicators, productivity, and import competition. With a strong empirical focus on China and its global rise, he maintains a critical understanding of the data-generating process and institutions in China. He acts as spokesperson for Leibniz Research Network “China”, an ECB expert‑network member and board member. He once worked at Peking University, advised global institutions, and is now a Qiushi Scholar at Renmin University of China.
Abstract:
We develop a new method to measure the importance of a patent for subsequent innovation, based on the use of a Large Language Model to process patent text data and a new model of the innovation process. We apply this method to study the evolution of patenting in China from 1985-2019, also classifying patent ownership using a comprehensive business registry. Our analysis yields seven novel facts about Chinese patenting. Among these are that patenting has become narrower and less innovative over time; that knowledge within China has become more important than knowledge outside of China for directing innovative activity in China; and that knowledge produced by Chinese entities within China has been more important than knowledge produced by foreign entities filing patents in China.
