Renormalizable Quantum Gauge Theory of Gravity

The quantum gravity is formulated based on the principle of local gauge invariance. The model discussed in this paper has local gravitational gauge symmetry, and gravitational fieldis represented by gauge field. In the leading-order approximation,it gives out classical Newton's theory of gravity. In the first-orderapproximation and for vacuum, it gives out Einstein's general theory of relativity. This quantum gaugetheory of gravity is a renormalizable quantum theory.
