交叉中值模型在物流设施选址中的应用研究

城镇化目前已经成为扩大改革开放的一项重要举措,但随着而来的就是相关基础服务设施不完善,严重影响了新城镇广大居民的生活质量和水平。因此,对于新建城镇相关物流服务设施的选址问题就变得尤为重要,交叉中值模型则是一个城镇区域内单一设施连续点选址的非常适合的方法。     

Does china income FSDs follow Benford? A comparison between Chinese income first significant digit distribution with Benford distribution

Since Benford’s law is an empirical phenomenon that occurs in a range of data sets, this raises the question as to whether or not the same thing might be true in terms of the Chinese income distribution data. We focus on the first significant digit (FSD) distribution of Chinese micro income data from the 2005 Inter-Census sample, which corresponds to 1% of Chinese population and other micro income data from the China family panel studies (CFPS) and Chinese General Social Survey (CGSS). We use information theoretic-entropy based methods to investigate the degree to which Benford’s FSD law is consistent with the FSD of Chinese income data and our findings suggest consistency between the Chinese FSD income distribution and Benford’s distribution. The close connection between the two distributions has implications for the quality of the sample of Chinese micro data.     

宗地规模、城市类型与土地出让溢价——基于70个大中城市住宅用地出让数据的实证分析

研究目的:确定住宅用地出让溢价率水平与宗地规模之间的关系,比较不同规模和区位城市中这一关系的差异。研究方法:理论分析,面板数据分析。研究结果:总体上宗地规模对土地溢价率的影响呈现"倒U"型变化关系,不同规模和区位城市中这一关系有差异。人口介于500万～1 000万之间的特大城市中土地溢价水平受宗地规模的影响较为强烈,东部和中部城市中宗地规模大小对土地溢价水平影响显著,西部城市不显著。研究结论:地方政府在总量既定条件下调整宗地投放规模可在一定程度上调控土地溢价率。     

Making the next move: When does the newness of experience matter in overseas sequential entries of multinational companies?

Traditional internationalization models suggest multinational companies (MNCs) can exploit their accumulative experience to facilitate their sequential entries. However, experience may depreciate over time. Thus, obtaining benefits from prior experience for MNCs is based on two critical premises, i.e., interpreting and applying experience correctly. We argue that there is a need to study the newness dimension of experiential learning. In doing so, we aim to explore to what extent the newness of experience matters in overseas sequential entries for MNCs. Moreover, we expect that the benefits from recent experience in guiding sequential entries are contingent on the extent of context similarity between the most recent entry location and sequential entry location and the outcome expectancy of focal entry. With a sample of 112 Chinese listed firms and 410 observations during the period of 2000–2012, we find that else being equal, the newness of experience of MNCs is positively associated with sequential entry and such a relationship is positively moderated both by context similarity in institutional environment and the outcome expectancy of the focal entry. We also compare the effects of the newness of different types of experience and find that the newness of the most recent experience has a larger influence on sequential entry than location-specific experience and general experience.     

我国台商投资大陆区位选择影响因素的实证研究

选取1991—2011年我国台商投资大陆地区各省(地区)相关变量的历史统计数据,采用面板数据分析方法,建立各时段面板数据模型,对我国台商投资大陆区位选择的影响因素进行实证分析。研究结果显示:影响我国台商投资大陆区位选择的因素主要有产业结构、政府政策、生产效率、基础设施、劳动力成本和开放水平等;其中,政府政策和开放水平是影响台商投资大陆区位选择的稳定且主要的因素;产业结构、基础设施和劳动力成本的影响次之,生产效率的影响并不显著;各因素对台商投资大陆区位选择的影响程度和方向不断变化,即产业结构的影响呈上升趋势,基础设施和劳动力成本的影响逐渐减弱。     

An economic–geographic assessment of the potential for a new air transport hub in post-Gaddafi Libya

Post-war Libya is faced with the challenge of adopting an air transport strategy for the future. One issue is how to address projects inaugurated under the Gaddafi government, such as the terminal extension at Tripoli International Airport. Additionally, the state-owned Afriqiyah Airlines had been establishing a niche hub in Tripoli before the 2011 war, but this development has subsequently been stalled.Against this background, we analyse the prospects of an air transport hub operation in Libya, focusing on traffic between Africa and Europe, from a bird’s-eye economic–geographic view. First, a literature review is undertaken to identify general success factors for air transport hubs. Second, a weighted average distance penalty (WADP) indicator is developed and applied to Tripoli as a potential hub location. This indicator considers all 4755 O&Ds between Europe and Africa with more than 100 passengers in 2012. For sensitivity reasons, alternative WADPs are estimated for the 3209 traffic flows not including North Africa and for (forecasted) future air traffic demand in 2020. The results for Tripoli International Airport are benchmarked against competing hub locations, such as Algiers, Cairo, and the major European airports. We conclude by discussing the implications of the current and anticipated future security and economic situation in the country.     

Employee satisfaction and turnover intention: A comparative analysis between front-of-house and back-of-house employees in casino-entertainment venues

ABSTRACT

This study investigates job location and its relationship with employee turnover intention within the casino-entertainment industry. The researchers analyzed turnover intention at the supervisor and company level from the perspective of employees who hold front-of-house or back-of-house jobs in three Nevada casinos and their corporate office. The results of this research fill existing gaps in the academic literature related to turnover intention and provide beneficial implications for industry and academic practitioners. Organizations within the casino-entertainment industry may develop strategies related to the management of human capital that could provide fiscal and operational benefits.     

A model for planning locations of temporary distribution facilities for emergency response

We propose a network flow model for dynamic selection of temporary distribution facilities and allocation of resources for emergency response planning. The model analyzes the transfer of excess resources between temporary facilities operating in different time periods in order to reduce deprivation. Numerical analysis shows that the location of temporary facilities is determined by the demand and supply points. This work contributes to the emergency response planning that requires a quick response for the supply of relief materials immediately after a disaster hits a particular area.     

基于网络DEA交叉效率模型的我国商业银行效率评价研究

本文从商业银行的实际情况出发，将其经营过程划分为资金筹措与资金运营两个阶段。结合网络DEA与权重平衡交叉效率思想，并利用熵值法处理交叉效率的集结问题，构建了商业银行各子系统及链形系统的交叉效率评价模型。将上述模型应用于我国16家商业银行的效率评价，发现这16家商业银行的效率普遍不高，且城市商业银行的系统平均交叉效率高于国有银行，国有银行的系统平均交叉效率略高于股份制银行。
