基于双边视角的零售商运营研究

供应商的多样化和差异化,是零售平台的普遍特征。不同于源于供应商多样化的组间网络效应,源于差异化的供应商对顾客的边际组间网络效应是递减的,同时带来供应商间的负的竞争效应。研究发现,随差异化竞争的供应商数量增长,零售商对供应商的组间网络效应补贴下降,并向供应商收取源于差异化竞争的价格加成,限制差异化竞争的供应商数量。供应商间的差异化度越低,最优的差异化供应商数量越少。零售商在供应商多样化和差异化之间权衡选择的差异,形成零售商服务的差异化,有利于缓和零售商间的竞争。     

服务贸易对澳门经济增长的贡献研究——基于澳门1998～2010年季度数据实证分析

文章在出口扩展型总量生产函数模型的基础上,从供给的视角实证分析了劳动、资本特别是服务贸易对澳门经济增长的影响和贡献。从1998年2季度至2010年2季度的季度平均值来看,资本和劳动投入对澳门经济增长的贡献份额分别为12%和9%,贡献率较低,而服务贸易总额对经济增长的贡献份额为75%,贡献率较高。面对全球金融危机,澳门必须调整一业独大的产业结构和过度依赖服务贸易的增长模式,实现产业结构适度多元化,不断催生新的经济增长点。     

我国旅游上市公司多元化经营绩效分析

根据多元化—效率—绩效的研究思路,经过对2000-2009年沪深两市三种不同类型的旅游上市公司多元化经营绩效进行实证分析。发现饭店类上市公司的相关多元化和绩效有显著的正相关关系;资源类旅游上市公司的相关多元化和绩效有显著的正相关关系,但是这种正相关关系并不是通过效率联结的;综合类旅游上市公司的相关多元化和绩效呈不显著负偏相关,通过效率也和绩效不显著偏相关,但是两者效果叠加则显著负相关。     

“五个重庆”建设效果的阶段性评估与思考

对重庆市民的调研表明,“五个重庆”建设在提高重庆影响力、增强市民信心和认同感等方面效果明显,市民对其成效普遍认同,并认为“五个重庆”建设意义重大,具有推广价值;其中,“森林重庆”建设成效最为显著,而“畅通重庆”、“平安重庆”、“健康重庆”、“宜居重庆”依次减弱。“五个重庆”理念体现了城市的多元化和可持续化发展,也坚持了以人为本,为城市发展指明了方向,对重庆市城市发展具有积极意义,也值得其他城市借鉴。重庆应持续、统筹推进“五个重庆”建设,人人参与“五个重庆”建设。

新疆非税收入运行状况分析

伴随着新疆经济的快速发展和税收规模的扩大,非税收入也呈现出快速增长的趋势,非税收入在缓解新疆地方财政支出压力、公共品融资难等方面发挥了重要作用。但在现行财税体制框架下,新疆非税收入运行中还存在诸多深层次的问题,其对外部性的校正及对经济的调节功能尚没有充分发挥。本文通过对新疆非税收入运行状况以及存在的问题和影响因素进行分析,进而提出了进一步完善非税收入管理的政策建议。     

Knowledge sharing in revenue management teams: Antecedents and consequences of group cohesion

The practice of Revenue Management has received widespread acceptance in the international hospitality industry yet a lack of best practice in terms of organizational integration persists. This paper follows the notion that revenue management is first and foremost a human activity, dependent on knowledge exchange and concerted decision within revenue management teams. One critical attribute of effective teams is group cohesion. The authors contrasted communication networks of 38 revenue management teams by means of social network analysis to identify the antecedents and consequences of group cohesion. It was found that industry employment, age and revenue management experience define the structure of communication networks and that awareness of other's expertise is central in explaining differences team performance across the sample. The findings highlight the issue of knowledge asymmetry in teams and suggest that the Revenue Manager occupies a more active role as an information broker in order to enhance group decision making.     

On the fairness of airlines’ ticket pricing as a result of revenue management techniques

Pricing and availability of tickets have always been a source of confusion for customers in transportation industries. What is the best time to buy tickets? Why passengers taking the same flight might pay significantly different prices for the same seat? Why round trip tickets between two cities sometimes become cheaper than the one-way flights between them? Is it fair to buy a ticket for an itinerary cheaper than a ticket for just a part of it? These observations make customers wonder why they pay higher prices for shorter flights. In this paper, we study the airlines’ revenue management systems and explain some of these pricing schemes in travel industries. We develop a simulator to study the decision making process of network revenue management and use a numerical study to explore these questions and address some explanations for them. We relate these observations to the revenue management measurements such as the bid price or the adjustment cost and show how the dynamic of the network get influenced by these measures that eventually results in unusual pricing. We explain how a zero or small bid price of a specific leg may cause the price of an itinerary be cheaper than one segment of it and that the small bid price is caused by low demand in comparison to the available capacity. We exhibit network revenue management system and show the above issues for a small network.     

Diversification,Performance, and the Corporate Life Cycle

This paper investigates the relation between the extent of diversification in firms and their performance at different life cycle stages. To illustrate the joint endogeneity of diversification and performance, we treat both the extent of diversification and firm performance as endogenous variables in a simultaneous equation system. Empirical results reveal that corporate diversification erodes firm value. Overall, firms in their growing stages experience a significant diversification discount; however, mature firms do not show such findings. Although unrelated diversification leads to trading at a discount in all growing and mature firms, conversely, related diversification exhibits an evident premium in mature firms.     

产业多元化：微型经济体国际比较

澳门产业多元化问题是内地和澳门特区政府以及学术界十分关注的问题。根据产业组织理论,对澳门以及和澳门类似的3个经济体——卢森堡、冰岛和马耳他的产业部门数量和各产业部门在整个经济中的分布进行了比较。使用就业人口和GDP数据计算出的熵指数和赫芬达尔指数显示,澳门的产业多元化程度低于卢森堡、冰岛和马耳他。研究也发现：导致澳门产业多元化程度低的主要原因不是澳门产业部门的数量少,即所谓的＂产业结构单一＂,而是各产业在澳门整个经济活动中的比重不均衡,即所谓的（博彩产业）＂一业独大＂。研究结论可为澳门特区政府制定产业多元化政策提供参考借鉴。
