Considering a basin composed of multiple upstream and downstream regions with the pollution occurring across regional boundaries, a Stackelberg game model is developed to investigate the multiple ecological compensation strategies for transboundary pollution control. The results show that (1) under the equilibrium strategy of ecological compensation all regions obtain a Pareto improvement result. (2) Ecological compensation results in an increase in total abatement investment. In particular, a very interesting result is that (3) rising abatement costs in a region compensate more for its upstream regions, whereas its downstream regions do not compensate more for it.

流域跨界污染治理多重生态补偿策略分析

考虑一个由多个上下游区域组成的流域，污染发生在跨区域边界，建立Stackelberg博弈模型来研究跨界污染控制的多重生态补偿策略。结果表明：（1）在生态补偿均衡策略下，所有区域均获得了帕累托改进结果。（2）生态补偿导致减排投资总量增加。特别是，一个非常有趣的结果是（3）一个地区不断上升的减排成本对其上游地区的补偿更多，而其下游地区并没有对其进行更多的补偿。
