At the heart of their concerns is the lack of sustained demand needed to drive growth. While structural reforms – particularly on the supply side – are required in developed and developing countries, they are not sufficient to address what former US Treasury Secretary Larry Summers has called “secular stagnation” – that is, the difficulty of sustaining sufficient demand to permit normal levels of output.
他们忧虑的核心是缺乏推动增长的持续性需求。虽然结构性改革——尤其是供应改革在发达和发展中国家同样必要，但单纯的结构改革还不足以解决前任美国财长拉里·萨默斯所谓的“长期停滞” 问题——也就是难以找到足够的需求允许产能正常释放。
