Economics is regarded as a branch of applied physics.* Wealth is defined exact quantitatively as wealth ring. Wealth ring consists of production sector, exchange sector, consumption sector, and environmental sector. This is a logical expansion of traditional economics of supply and demand. Money is defined as a universal exchanger. By extending the conservation laws in physics to economics, a fundamental exact quantitative theorem has been found to be obeyed by wealth creating activities. This new way of economics analysis has seven quantum frameworks that are abstracted, from quantum field theory. The immediate advantage is to give an analytical way to increase wealth of nation. We have used it to understand the rapid rise of wealth in China in thirty years from 1980 to 2010. Other nations and other entities could use similar analytical method to increase their wealth rapidly. The evolution of human society is considered, to evolve from hunter-gatherer society to agricultural society, from agricultural society to industrial society, and now should evolve from industrial society into an ecological society.
