最新报道:Countries with the largest shadow economies, measured as a percentage of GDP, include Zimbabwe (60.6%), Bolivia (62.3%), and Georgia (64.9%), according to World Bank data. These informal markets, operating outside government regulation, thrive due to high taxes, complex regulations, and weak enforcement. While providing livelihoods, shadow economies reduce tax revenues and hinder economic growth. Developed nations like Switzerland (6.9%) and the U.S. (8.3%) have smaller informal sectors due to stronger institutions and lower corruption. Experts suggest simplifying tax codes and improving governance to reintegrate shadow activities into the formal economy.
