The document provides a comparison of tax systems and revenues in China and OECD countries. It finds that China's tax-to-GDP ratio is lower than the OECD average, at 21.9% versus 34% in 2010. China also relies more on indirect taxes like VAT and less on direct taxes like personal and corporate income taxes compared to OECD averages. Tax revenues in China have consistently grown faster than nominal GDP since the 1990s due to tax reforms, economic growth, and improved administration.
