Quantitative researchers in economics and finance face a persistent challenge when studying the Chinese market: tracking, classifying, and quantifying policy interventions. Because the Chinese economy is heavily influenced by state-directed directives, regulatory shifts, and multi-year development plans, government announcements act as major economic events. In academic literature, these are analyzed as "policy shocks"—abrupt, exogenous changes in the regulatory or economic environment that allow researchers to study market behavior, corporate reactions, and macroeconomic shifts.

The Python-based project china-policy-shocks positions itself as a specialized solution to this challenge.
