中文摘要：

供给侧改革的重点在于优化劳动力、资本和科技投入等要素的配置，而民营经济是中国经济转型的重要引擎，文章从供给侧视角研究了1992—2014年民营经济增长的要素配置效率及其时空演变轨迹。结论如下：从时间角度看，民营经济增长表现为资本与技术双驱动特征，且资本与技术呈现动态“螺旋式”交替状态，劳动驱动强度在2008年后有所上升；在空间分布上，民营经济增长空间重心偏向东南地区，资本重心在近年来开始转向中部地区，劳动力重心偏向东部地区，技术重心偏向东南地区；在区域范围内，各区域民营经济增长类型均以资本驱动型为主，长三角和东南沿海地区的科技创新和人力资本优势并未显现，东北经济区民营经济增长整体效应最低。
