This paper takes Cobb-Douglas production function as the theoretical framework. Spatial Moran index of autocorrelation, Spatial Lag Model(SLM) and Spatial Error Model(SEM) are used to analyze the star-rated hotels labor productivity of 31 provincial regions in China's Mainland based on the star-rated hotels statistical data of year 2016. The spatial correlation and spatial difference of the star-rated hotels labor productivity is discussed. This paper studies the impact of three factors on spatial characteristics of star-rated hotels labor productivity in China's Mainland. The econometric estimation results show that:(1) Star-rated hotels labor productivity present significant spatial dependence and spatial difference in China's Mainland.(2) The estimation results of Ordinary least Squares(OLS) are reliable.(3) The reliability of the results obtained by the Spatial Error Model(SEM) analysis is the highest, and has a stronger explanatory power to the spatial relationship of star-rated hotels labor productivity in China's Mainland. The average room occupancy rate has more influence on the labor productivity of the provincial star-rated hotels than the impact of capital and labor.展开更多
In this paper, 5 high-rise hotels in Xi'an were selected for research, their energy consumption data from 2015 to 2016 were collected and analyzed, their comprehensive energy consumption per unit area was compared...In this paper, 5 high-rise hotels in Xi'an were selected for research, their energy consumption data from 2015 to 2016 were collected and analyzed, their comprehensive energy consumption per unit area was compared by using the standard coal coefficient, and their energy use characteristics and influencing factors were obtained. The test analyzed various parameters of the indoor environment and evaluated the indoor environmental quality according to the specifications and standards. Starting from the perspective of energy use systems, this paper found energy consumption priorities and problems of these hotels, and proposed feasible energy conservation measures, in a view to providing a reference for energy conservation design of high-rise hotels in Xi'an.展开更多
高维数据下的均值检验是统计学检验的重要组成部分.在高维情形下,样本协方差矩阵往往是奇异矩阵,传统的均值检验方法因此失效.为解决该问题,对高维数据进行分段,使分得的每一段的维数均小于样本容量,继而运用Hotelling T 2检验依次对每...高维数据下的均值检验是统计学检验的重要组成部分.在高维情形下,样本协方差矩阵往往是奇异矩阵,传统的均值检验方法因此失效.为解决该问题,对高维数据进行分段,使分得的每一段的维数均小于样本容量,继而运用Hotelling T 2检验依次对每一段进行检验,同时给出一种控制犯第一类错误的概率的新方法,使原假设下的检验水平稳定在事先给定的显著性水平左右.经模拟显示,该逐段检验方法比已有方法能更好地控制犯第一类错误的概率.展开更多
