Impact of Operating Conditions on the Productivity of Star-Rated Hotels in China's Mainland: Verification from Spatial Metrology

引用

Journal of Landscape Research 2019年第1期11卷 87-89,94页

作者： XIE Ailiang LI Xiubiao liu zhongxiu liu Chuanyu YU Feng Linyi University

Room occupancy rate is a key indicator of star-rated hotel management quality. 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.

长期以来,美国构建全球霸权的重要手段就是结盟,打造太空作战联盟也被美国视为称霸太空的重要方式。拜登政府上台后,美国在继续加强太空军事能力建设的同时,将发展太空作战联盟作为维护太空霸权新的战略选择。基于同盟理论,美太空作战联盟的核心力量包括但不限于日本、澳大利亚、韩国和北约。在大国竞争的背景下,除常规的联盟联合领域外,拜登政府还企图在外空规则、地月空间、商业太空战等领域作出新的联合尝试,并将原有“雁阵型”霸权主导式管理调整为基于利益协调和制度规则的联盟管理模式。自此,美太空作战联盟呈现出新的发展态势,这将对未来全球太空安全和我国家安全造成重要影响。

本文在分析协同创新网络结构特征与演进趋势的基础上,研究协同创新赋能制造业企业全球价值链攀升的影响效应和作用机制。研究发现:首先,我国协同创新网络规模扩张迅速,产业链领先企业、理工类高等院校和政府科研机构在网络中占据核心位置,呈现出明显的“核心—边缘”空间结构;其次,协同创新有助于提升企业出口国内附加值率,其影响机制主要通过提高市场势力和承接高技术生产环节实现;最后,协同创新网络的全球价值链攀升效应在具有较高生产和技术吸收能力、较低价值链位置和贸易壁垒风险的企业中更为突出。
