中国快递企业的空间组织研究——以顺丰速运为例

以顺丰速运为案例，分析其网点布局规律，并从组织模式和快递流量等方面探讨其空间组织网络，以此来探讨中国快递企业的空间组织。研究发现，快递企业空间组织网络总体呈现出为社会经济和人口服务的特征趋势，并与区域地形地貌、当地的区位条件和产业特征相关。快递企业的网点布局遵循行政级别越高的城市网点覆盖率越高，同一级别城市的网点覆盖率从南向北、从东向西递减的规律。随着市场的扩张，快递企业逐渐采用多层级分区域的空间组织模式，并根据区域社会经济发展状况、产业特征、交通情况等，形成基于不同服务时限等级的快递服务网络，整个营运网络逐渐由单枢纽轴辐式网络向多枢纽轴辐式网络变迁。同时，快递流量和流向与城市的吸引力、城市间关联关系体现出较好的一致性，顺丰速递华中区快递流量分析充分说明了上海、北京、广州和深圳在全国层面的较强吸引力和绝对中心的地位。     

我国消费者信心指标与股价指数的关联度研究

我国股市“非理性投机”、“弱式有效市场”的现状，造成我国如今股市低迷、投资者信心不足等严重的问题。而通过传统的技术分析和基础分析手段，无法对股市震荡、股价的波动进行完美的诠释，因而部分学者开始另辟蹊径，探寻能够更好解释股价变动的“第三条中间路线”。此时，我国消费者信心指标的编制与发布，为研究提供了全新的视角与思路。我国自2003年底开始编制并发布消费者信心指标，旨在从宏观整体经济发展，到微观股市汇市走势研究预测方面，发挥该指标强大的领先与预测功能。文章选取我国三组消费信心指标、上证综指与深证综指两组股价指数，通过相关性检验、因果检验与脉冲响应指数与方差分解等方式，不仅得出我国消费信心指标与股价变动之间较强的关联性，还通过分样本区间的讨论，得出股市衰退、股价下滑阶段，CCI指标与股价指数的关联度更大的结论。     

Not all emerging markets are the same: A classification approach with correlation based networks

Using dynamic conditional correlations and network theory, this study brings a novel interdisciplinary framework to define the integration and segmentation of emerging countries. The individual EMBI+ spreads of 13 emerging countries from January 2003 to December 2013 are used to compare their interaction structure before (phase 1) and after (phase 2) the global financial crisis. Accordingly, the unweighted average of dynamic conditional correlations between cross country bond returns significantly increases in phase 2. At first glance, the increased co-movement degree suggests an integration of the sample countries after the crisis. However, using correlation based stable networks, we show that this is not enough to make such a strong conclusion. In particular, we reveal that the increased average correlation is more likely to be caused by clusters of countries that exhibit high within-cluster co-movement but not between-cluster co-movement. Potential reasons for the post-crisis segmentation and important implications for international investors and policymakers are discussed.     

The pricing of deposit insurance in the presence of systematic risk

Based on the Merton (1977) put option framework, we develop a deposit insurance pricing model that incorporates asset correlations, a measurement for the systematic risk of a bank, to account for the risk of joint bank failures. Estimates from our model suggest that actuarially fair risk-based deposit insurance that considers only individual bank failure risk is underpriced, leaving insurance providers exposed to net losses. Our estimates also capture the size premium where big banks are priced with higher deposit insurance than small banks. This result is particularly relevant to the current regulatory concerns on big banks that are too-big-to-fail. Above all, our approach provides a unifying framework for integrating risk-based deposit insurance with risk-based Basel capital requirements.     

Locus of Control and Its Influence on Hotel Managers' Job Satisfaction

Abstract

Studies have demonstrated that internal/external locus of control impacts job satisfaction. Additionally, research indicates that locus of control relates to many other work-related perceptions. However, few studies exist that investigate the relationship between locus of control and job satisfaction for hotel managers. This study investigates hotel managers' job satisfaction (n = 68), internal/external locus tendencies, and the relationship between the two constructs. The results indicate that variables other than the locus personality construct may relate to hotel managers' perception of job satisfaction. Additionally, the results stimulate the ongoing person versus situation debate in job satisfaction research.     

我国财产保险市场的空间统计分析

以我国31个省(市、自治区)的保险密度和保险深度为属性数据,利用ArcGIS和GeoDa软件,运用空间统计方法,对我国财产保险市场的地区空间差异进行实证分析。结果表明:我国财产保险的保险密度与保险深度的分布特征在南北方向上基本一致,在东西方向上不一致;各地区保险密度的分离度高于保险深度的分离度;我国财产保险发展存在显著的空间自相关和空间聚集现象。     

基于中国电子制造业的固定资产与长期资本相关性的实证研究

固定资产和长期资本间的关系在企业财务管理中占有重要地位。文章以电子制造业上市公司为研究样本,证实固定资产与长期资本、长期负债正相关关系显著,而其与所有者权益正相关关系不显著,并对这种关系的合理性予以解释。     

中国进出口贸易与国内物流业发展关联性计量分析

针对学术界争论的中国物流发展与中国进出口贸易发展之间是否存在关联性,以及若存在关联性其具体表述如何这一系列问题,从宏观分析人手,对中国物流业发展、进出口贸易发展进行综合分析.在此基础上,利用皮尔逊相关系数检验方法确定了三者之间的关联性,随后利用计量分析方法确定了三者之间具体的关联性关系,从而有效地解决了困扰学术界的这一问题.     

管理层股权设置与上市公司绩效的实证研究

本文运用非线性相关分析方法,检验了管理层股权设置(MSR)与公司经营绩效(ROE,Tobin‘sQ)之间的关系。结果表明,两者存在显著的非线性关系。通过系数矩阵的正负统计分析发现,国外学者提出的“利益趋同效应“和“掘壕自守效应“在我国上市公司中同样存在。同时还发现,公司的经营业绩与高管人员的持股比例存在区间效应。实证结果在否定税盾假设、企业成长假设、资产性质相关性假设的同时,肯定规模相关假设。
