Cost Efficiency of International Tourist Hotels in Taiwan: A Data Envelopment Analysis Application

This paper uses the data envelopment analysis approach to measure cost, allocative and overall technical efficiencies of international tourist hotels (ITHs) in Taiwan during 1997–2006. There are three outputs, three inputs, three input prices and four environmental variables in the empirical model. The cost inefficiency of these hotels is from overall technical inefficiency. International tourist hotels in Taiwan have an average efficiency of 57%. Chain systems, non-metropolitan areas and occupancy rate have significantly positive impacts on all efficiency scores of Taiwan's ITHs. The distance from the nearest international airport significantly worsens their efficiency scores.     

Performance Analysis of Lodging REITs in Relation to Market Segments

This article examines the financial performance of lodging real estate investment trusts (REITs) in relation to their market focus. Secondary data were collected for from 2004 to 2008 from lodging REITs that were traded on major U.S. stock exchanges. Data envelopment analysis (DEA) was used to assess the efficiencies of market segments to generate financial performance. The results showed that two lodging REITs were consistently efficient during the study period relative to other lodging REITs. In particular, lodging REITs investing and/or operating in one or more relatively similar market segments and those focusing on the upper-upscale segment were more efficient than others. This study could provide managers, owners, and investors of lodging REITs preliminary evidence of the relationship between market segments and firm performance. This article also proposes a framework for future investigations to assess the performance of REITs.     

旅游市场效率及其博弈分析--以旅行社产品为例

虽然我国旅游业发展迅速，国际、国内旅游收入总量大，但是旅游企业的效益和整体市场效率却较低，旅游供需处在一种低水平的均衡点上，为什么会产生这种现象呢?本文以旅行社产品为例，从旅游市场低效率的原因入手，通过对旅游市场博弈及其均衡结果的分析，指出目前只有政府加强市场监督管理，才是提高旅游市场效率的最佳策略选择。     

基于DEA方法的内外资星级酒店效率评价与差异分析——以东部省份14个城市为例

近年来,酒店投资规模不断扩大,但整体收益却不尽如人意,内外资星级酒店利润率差距明显。应用DEA方法对2011~2016年我国东部省份14个主要城市的内外资星级酒店效率进行评价,研究发现:从综合效率来看,虽然内外资酒店存在差异,但两者总体水平均较高,且两者波动趋势一致;从技术效率来看,外资酒店略高于内资酒店,两者差距不明显,且差距有缩小的趋势;从规模效率来看,内外资酒店均处于较高水平,但两者差距明显;从效率分类来看,不同效率水平下的内外资酒店技术效率和规模效率表现不同。据此,对内外资星级酒店综合效率与影响因素之间的关系进行了进一步研究。     

国有企业员工个体差异与提高整体效能初探

环境规制、技术创新与中国火电行业的效率提升

基于效率的视角,本文对2004年中国30个省(自治区、直辖市)火电行业的环境规制进行分析。首先利用三阶段DEA模型排除经营环境与统计噪音对中国火电行业效率的影响,然后从非规制、弱规制、强规制三个层次分析环境规制程度与中国火电行业效率的关系。实证结果表明,环境规制可以提升中国火电行业整体的效率水平,总体上存在技术创新激励效应,但并非适用各个地区。最后本文根据环境规制与技术效率的关系,将中国各地区火电行业的发展模式划分为内力驱动环境友好型、环境弱友好型和外力推动环境友好型三种,并给出各自适应的规制建议。     

A stage-dependent model of resource utilization,strategic flexibility,and implications for performance over time: Empirical evidence from a transitional environment

It has long been recognized that there is a tradeoff between exploration and exploitation. How organizations utilize resources across time and space will affect firm survival and growth. In this paper, we examine resource utilization and performance implications over time in an environment undergoing fundamental institutional transformation. Based on a large archive of Chinese government data from 1988, 1992, and 1996, the study finds that (1) the impact of resource utilization is contingent on the degree to which different resources are committed to factors of production, (2) the impact is curvilinear and only valid within an “optimal” range, and (3) the performance implications change over time. As firms enter later stages of the transitional process, efficiency becomes less important as they shift their strategic focus from exploitation to exploration, which requires more flexibility. These findings have significant bearing on the issue of upgrading technological competitiveness in China as the country becomes increasingly integrated in the global economy. Such insights may also have implications for other emerging economies in Asia.

Fuzzy Pair-wise Dominance and Implications for Technical Efficiency Performance Assessment

Classically, the concept of efficiency measurement is based on the definition of a frontier that envelops the observed production plans. The efficiency score itself is based on the distance of an observed production plan from this frontier. The frontier along with the required technological assumptions (such as convexity) needed for its definition may be replaced with the concept of pair-wise dominance. This concept leads to a classification scheme for all production plans instead of a ranking based on efficiency scores. Also, the traditional assumption of deterministic or crisp production plans may be substituted with the weaker assumption of fuzzy production plans as proposed by fuzzy set theory. This paper merges these two concepts and defines a new classification scheme based on fuzzy dominance.
