Abstract  There has been a new synthesis in theory in economics in the later period in 20th century. Employing the mathematical dual theorem, the new paradigm in leading edge in economics has been generated, which is the restricted profit function, or named G function in this paper. G function has been advancing the economic research to reach new level of leading edge, in which the theory of economics is going deep into and expanding. It lets economics develop into the new stage. The important progresses have appeared in economics. They have brought the new minds, the new trains of thought, and the new methods about economics.
