The Anatomy of Chinese Innovation: Insights on Patent Quality and Ownership
Philipp Boeing, Loren Brandt, Ruochen Dai, Kevin Lim, Bettina Peters, May 07, 2025Chinese patenting has become narrower and less innovative over time. The role of overseas knowledge has also declined sharply. These findings are salient in the context of a marked slowdown in economic growth in China and rising concerns of technological decoupling with the US.
Structural Change and the Stability of Aggregate Employment in China
Wen Yao, Xiaodong Zhu, Oct 27, 2021In developed countries, aggregate employment has a strong positive correlation with aggregate output, and it is almost as volatile as output. In China, the correlation of aggregate employment and output is close to zero, and the volatility of aggregate employment is very low. We argue that the key to understanding the stability of aggregate employment in China is labor reallocation between the agricultural and non-agricultural sectors, and that the declining relative demand...
The Impact of the COVID-19 Pandemic on Consumption: Learning from High Frequency Transaction Data
Haiqiang Chen, Wenlan Qian, Qiang Wen, May 26, 2021Based on daily transaction data in 214 cities and the difference-in-differences method, we document that daily offline consumption fell by 32%, or 18.57 million RMB per city, during the twelve-week period after China’s COVID-19 outbreak in late January 2020. This implies that China’s offline consumption decreased by over 1.22 trillion RMB in the three-month post-outbreak period, or 1.2% of China’s 2019 GDP. Our estimates suggest a significant economic benefit...
Trade Policy Uncertainty and Firm Innovation
Qing Liu, Hong Ma, May 12, 2021This study proposes a novel channel through which trade liberalization may induce innovation through the reduction of trade policy uncertainties (TPU) in destination markets. To verify this link, we utilize the significant reduction of TPU engendered by China's accession to the World Trade Organization (WTO) in 2001 as a quasi-natural experiment. We find that reduction in TPU significantly encourages firms' patent applications and that firms' innovation responses to TPU reduction vary by productivity, ownership, exporting status, and the irreversibility of investment.
