To the extent that this approach reflects the view that policymaking is an art, not a science, that is a good thing: the world needs more flexibility in economic policymaking. But some might consider it a cause for concern, especially given growing suspicion of incentive-based economic policies in the wake of the global economic crisis.
这一方针体现了决策是一种艺术而不是一种科学的观点，这是件好事：在经济决策中，我们需要更多的灵活性。但一些人可能会认为这值得担忧，特别是在全球经济危机导致越来越多的人怀疑基于激励的经济政策时。
