城乡分治制度的若干表现及其内核

城乡分治的二元制度以城乡二元户籍制度、财政属地化管理制度、城乡分治的规划管理制度为核心制度,继而由核心制度演绎出来系列城乡二元制度体系,其中以地区划分的城乡二元核心制度的衍生制度有城乡二元建设管理体制、城乡分治的公共基础设施建设管理制度、城乡经济管理分治等制度,以人口划分的城乡二元制度的衍生制度有城乡分治的社会保障制度、城乡分治教育制度、城乡二元就业制度、城乡分治的住房制度。城乡二元核心制度及其衍生制度构成我国城乡二元制度体系。     

ADMM for Penalized Quantile Regression in Big Data

Traditional linear programming algorithms for quantile regression, for example, the simplex method and the interior point method, work well for data of small to moderate sizes. However, these methods are difficult to generalize to high‐dimensional big data for which penalization is usually necessary. Further, the massive size of contemporary big data calls for the development of large‐scale algorithms on distributed computing platforms. The traditional linear programming algorithms are intrinsically sequential and not suitable for such frameworks. In this paper, we discuss how to use the popular ADMM algorithm to solve large‐scale penalized quantile regression problems. The ADMM algorithm can be easily parallelized and implemented in modern distributed frameworks. Simulation results demonstrate that the ADMM is as accurate as traditional LP algorithms while faster even in the nonparallel case.
