The key to a successful growth strategy is to ensure that policies reinforce and enhance one another. For example, boosting returns on public investment – critical to any growth plan – demands complementary policies and conditions, in areas ranging from resource allocation to the institutional environment.
成功增长战略的关键是确保政策之间要相互加强和强化。比如，提振公共投资回报——对任何增长计划，这一点都是关键——需要相辅相成的政策和条件，从资源配置到制度环境在内的诸多领域都是如此。就效率而言，一揽子政策要大于各部分之和。
