中文摘要：

改革开放后中国经济缔造了令世界瞩目的高速增长奇迹,支撑高增长的传统动力表现为：需求层面主要依靠出口和投资,供给层面主要依靠要素投入规模扩张,产业层面主要依靠工业带动.近年来我国经济步入“中高速”、“优结构”、“新动力”和“多挑战”的新常态,传统动力衰弱,新生动力孕育成长,主要表现在：需求动力转向消费,供给动力转向创新驱动,产业动力转向服务业.然而新旧动力的转换面临系列障碍,消费成长乏力、创新驱动需要驱动创新和现代服务业发展相对滞后等.由此,应建立“消费成长＋科技创新＋现代服务业发展”三位一体的经济发展新动力机制,为新动力的成长壮大提供制度保障,以优化经济结构、支撑中高速和有质量的经济增长.
