Now about purchasing power parity has even become a task for international organizations to study, for example, the United Nations Statistical Commission commissioned the World Bank to organize countries to study purchasing power parity across the world.　　Because of the low price of some goods and services in developing countries, if we convert GDP from PPP to comparable economic aggregates, the economic aggregates of developing countries will be revised upwards.
