As the late Yale economist Gustav Ranis observed nearly 20 years ago, the key to successful and sustainable development is “avoiding the encrustation of ideas.” For Chinese policymakers, this means recognizing the need to abandon some of the fundamental ideas that underpinned the economy’s past growth, before they become so firmly encrusted that they jeopardize the country’s development prospects.
已故的耶鲁经济学家古斯塔夫·拉尼斯（Gustav Ranis）在近20年前观察道，成功而可持续的发展的关键是“避免思维僵化”。对中国决策者来说，这意味着认识到必须在一些作为中国经济过去增长基础的基本思维形成顽固惯性、破坏中国发展前景之前抛弃它们。
