内容简介:The classical prisoner dilemma game on networks ignores the heterogeneity of players that may lead to the remarkable differences of their payoffs in reality. With the consideration of the heterogeneity, we propose an investors’ power-based game, where the payoffs of defectors depend on the efficiency of market and the related-power against cooperators. Economically, the efficiency of the market of investment is introduced in the game through a parameter α that becomes a key factor in the evolutionary process. Our simulation results show that, an improvement of efficiency benefits for the cooperation fundamentally. Furthermore, comparing with the result on BA scale-free networks, the evolution of cooperation performs great stability on WS small-world networks against the change of market efficiency. As the network of investment in real world may possess both of the properties of WS small-world networks and BA scale-free networks, the findings may be helpful in understanding and controlling the behaviors on the network of investment.
