The most familiar use of GDP is to evaluate a country's economic position in certain period. The oversimplification of GDP lies in that it is a criteria only concerns aggregate income without removing revenues from the impunities or those harmful products and services: criminal behaviors, repeated construction, excessively advanced construction, military sales and etc.

When measuring the truly positive GDP, not only these apparently unnecessary or even harmful GDP contributors should be expelled, but also the cost of side-effects including environmental pollution and social problems of the increasingly open and competitive market economy should be counted.

From the perspective of building a positive GDP, the central government plays the role of a GDP refiner by directing the recent series of administrative campaigns-anti-corruption, anti-drug, anti-trust, housing price control and etc.-which may slowdown the China's rapid economic growth but actually fasten seatbelt in a critical time full of opportunities and crises.

While we are still making the cake bigger, we make it more nicely.
