The Robnik billiard is investigated in detail both classically and quantally in the transition range from integrable to almost chaotic system. We find out that a remarkable correspondence between characteristic features of classical dynamics, especially topological structure of integrable regions in the Poincar\'{e} surface of section, and the statistics of energy level spacings appears with a system parameter $\lambda$ being varied. It is shown that the variance of the level spacing distribution changes its behavior at every particular values of $\lambda$ in such a way that classical dynamics changes its topological structure in the Poincar\'{e} surface of section, while the skewness and the excess of the level spacings seem to be closely relevant to the interface structure between integrable region and chaotic sea rather than inner structure of intergrable regoin.
