生态系统服务付费（PES）是一种流行的环境保护战略，特别是热带森林保护。然而，人们对其有效性知之甚少。许多人认为，即使生态系统服务付费在付款持续期间增加了养护，但从长远来看，它们可能会对有利于环境行为的其他动机产生不利影响。我们测试是否有条件的付款也鼓励森林用户保护共享的森林资源后，付款结束。通过对5个国家的1,200名热带森林使用者进行的框架实地实验，我们发现：（1）在干预期间，有条件支付增加了保护行为;（2）在支付停止后，使用者平均比干预前继续保护更多，特别是当他们能够相互沟通时;信任增强了干预措施的持久保护效果。当干预措施促进人际交流，并在森林用户享有高度信任的情况下执行时，生态系统服务费用支付的效力可能会增加。
Payments for Ecosystem Services (PES) represent a popular strategy for environmental protection, and tropical forest conservation in particular. Little is known, however, about their effectiveness. Many argue that even if PES increase conservation while payments last, they may adversely affect other motivations for pro-environmental behaviour in the longer term. We test whether conditional payments also encourage forest users to conserve shared forest resources after payments end. Using a framed field experiment with 1,200 tropical forest users in five countries, we show that (1) during the intervention, conditional payments increased conservation behaviour; (2) after payments stopped, users continued to conserve more on average than they did before the intervention, especially when they were able to communicate with each other; and (3) trust amplified the lasting conservation effects of the interventions. PES effectiveness may increase when interventions facilitate interpersonal communication and when implemented in contexts where forest users enjoy high levels of trust.
