Abstract: Cooperation plays an essential role in the development of human civilization. How to promote the emergence of cooperation has always been a hot research topic. Addressed in this paper is the evolutionary process of voluntary public goods game on a regular lattice. A preferential-selection and expected-payoff mechanism is proposed to promote cooperation level. This mechanism combines two factors-preferential selection and expected payoff and possesses two conspicuous advantages: 1. Overcome some defects of reported mechanisms and be more reasonable. 2. Promote cooperation level of the considered game. Specially, simulations show that appropriate expected payoffs can improve cooperation level no matter what value of preference parameter is, avoiding excessively low cooperation rate when the preferential parameter is negative.
