将“progressivity"翻译成中文

However, as both capacity and infrastructure develop, incentives are less important than an effective and progressive enabling environment.

但当能力与基础结构有所发展以后,奖励便不如有效、累进的积极环境来得重要。

Obviously, growth accompanied by progressive distributional change is better than growth alone for poverty reduction.

显然,就减贫而言,在进行渐进性分配改革的同时实现的增长比单纯的增长更好。
