摘要翻译：
我们提出了一个扩展的公共物品互动模型来研究异质人口中合作的演化。投资者被安排在众所周知的无标度型网络上，即Barab{a}si-Albert模型。每个投资者都应该根据对资金池规模的了解，优先将资金分配到其投资组合中的资金池。投资者偏好较大池的程度由投资策略决定，投资策略由一个可调参数$\alpha$表示，较大的$\alpha$对应于对较大池的更多偏好。作为比较，我们还研究了正方形晶格上的相互作用模型，发现非均匀接触有利于合作。此外，还讨论了在不同的$\alpha$策略下，局部拓扑结构对博弈动力学的影响。研究发现，采用较小的$\alpha$策略的系统比采用较大的$\alpha$策略的系统性能要好。

英文摘要：
We propose an extended public goods interaction model to study the evolution of cooperation in heterogeneous population. The investors are arranged on the well known scale-free type network, the Barab\'{a}si-Albert model. Each investor is supposed to preferentially distribute capital to pools in its portfolio based on the knowledge of pool sizes. The extent that investors prefer larger pools is determined by investment strategy denoted by a tunable parameter $\alpha$, with larger $\alpha$ corresponding to more preference to larger pools. As comparison, we also study this interaction model on square lattice, and find that the heterogeneity contacts favors cooperation. Additionally, the influence of local topology to the game dynamics under different $\alpha$ strategies are discussed. It is found that the system with smaller $\alpha$ strategy can perform comparatively better than the larger $\alpha$ ones.
