金融生态环境对银行监管目标的影响研究

本文选取适当指标衡量金融生态环境和银行监管目标,通过采用主成分分析(PCA)、ADF平稳性检验和格兰杰因果检验等计量分析方法,对2003~2011年间中国金融生态环境与银行监管目标之间相互作用的因果关系进行了实证研究。结果显示,金融生态环境对银行监管目标存在影响。具体地,宏观经济环境和信用环境对公平性目标具有显著影响;制度环境和监管环境对效率性目标具有显著影响;金融生态环境对于稳定性目标的影响则不太显著。     

商业银行偿付能力风险、流动性风险与银行体系风险

宏观审慎监管需要微观基础.研究商业银行偿付能力风险与流动性风险和银行体系风险的关系,有助于监管当局制定合适的监管工具,有效管理银行业的系统性风险.中国未曾爆发过真正意义的银行业危机,因而研究影响银行业系统性风险的因素成为难题.在借鉴风险二维定义属性基础上,本文对商业银行偿付能力风险和流动性风险如何影响银行业稳定进行了实证分析.分析结果表明,当商业银行偿付能力上升时,银行风险承担会上升,进而增加银行倒闭的预期损失;商业银行流动性风险的上升也会增加银行倒闭的预期损失;商业银行偿付能力提高时,流动性风险会降低;商业银行流动性风险上升时,偿付能力风险也上升.     

Seasonal concentration of tourism demand: Decomposition analysis and marketing implications

This paper analyzes seasonality in the United Kingdom, specifically the English regions in relation to tourists' place of origin and main travel motivation. The method used is a decomposition of the Gini index, which provides relative marginal effects that facilitate the identification of market segments open to counter-seasonal marketing efforts. This method has been combined with a graphical multivariate technique (biplot), which groups segments according to their seasonality characteristics. Seasonal patterns associated with particular segments differ significantly when studied on a disaggregated basis. Therefore, an adequate level of disaggregation is essential in the design of counter-seasonal strategies. Although this study focuses on British destinations, this methodology could be used as a control and monitoring measure in the regional analysis of any destination, facilitating regular adjustment of regional tourism marketing campaigns to minimize seasonality effects, specifically by targeting the types of tourists less prone to seasonality.     

用地理集中指数衡量游客集中程度方法的一个改进

地理集中指数用来衡量游客集中度存在着一些不足,其大小受到样本数量多少的影响,既没有一个衡量的标准,又不能进行不同样本数量的结果的比较,且不够直观。考虑引入完全均匀分布的地理集中指数,并计算其与地理集中指数之差,再运用这个差值与完全平均的地理集中指数之比来衡量游客集中度,并称这个比值为游客集中度系数,这一系数可以较科学、直观地反映游客集中程度。     

国有商业银行上市对银行业效率水平的影响——基于Malmquist生产率指数的实证分析

文章基于我国15家各类性质银行在1996-2010年经营效率数据基础上,利用数据包络分析法(DEA),对我国银行1996-2010年经营效率进行总体评价与分析,报告了我国银行业务经营效率水平。通过应用Malmquist生产率指数对银行业务经营效率变动得进行了调查和测量,结果反映了银行上市后银行业效率提高幅度明显,尤其是国有银行进步最快,但我国商业银行普遍存在规模报酬递减的状况,需要进一步提高规模报酬。从动态上看,我国银行业1996-2003年全要素生产率总体上出现小幅的下降,但2004年以后,随着国有银行逐步上市,我国银行业全要素生产率得到了稳步的提升。笔者认为我国银行需不断拓展表外业务、提高日常管理水平、吸收更多高学历人才和增加新兴技术的自主创新。     

中国水生蔬菜出口市场集中度和依赖度分析

[目的]水生蔬菜作为我国区域性特色明显的优势农产品,出口创汇能力强。以莲藕、芋头和荸荠为主要研究对象,分析其出口规模、产品结构和市场分布,可全面把握中国水生蔬菜的出口市场形势,有助于防范出口市场风险,以便更好地推进中国水生蔬菜出口市场的进一步优化。[方法]文章通过测算市场集中率和依赖度系数,对2012—2021年中国水生蔬菜的出口市场集中度与依赖度进行分析。[结果]中国水生蔬菜出口市场集中度高,由高到低依次为芋头、莲藕和荸荠;出口依赖性强,其中莲藕对马来西亚、日本、美国的市场依赖性强;芋头对日本、美国的市场依赖性强;荸荠对马来西亚、新加坡和越南的市场依赖性强。[结论]基于研究结果和发现,提出拓展新兴市场、提升质量标准、延长产业链条等建议,以降低水生蔬菜出口风险、提升国际竞争力,推动中国水生蔬菜更好地发展。

本文以上市公司数据为样本,采用主成分法、逐步回归、方差分析等多种分析方法对我国上市公司股权集中度影响因素进行了实证分析。结果表明,上市公司股权集中度的主要影响因素为持股主体、行业分布和规模,在此基础上还对我国上市公司的治理提出了建议。     

Bank Income Diversification,Asset Correlation and Systemic Risk

This paper explores whether the asset correlations among the non-interest activities of banks are the key causes for enhancing the bank diversification-systemic risk nexus. Our empirical evidence indicates that banks' income diversification significantly raises systemic risk. After removing those banks with high asset correlations, the effect of individual banks' diversification on banking systemic risk turns insignificant or even inverse. The results show that high asset correlations among banks could introduce bank failures, thereby leading to higher systemic risk in the financial sector.

Individual and Institutional Concentration of Leisure Research in North America

The purpose of this article is to identify key characteristics of the community of leisure scholars in North America and to use patterns derived from data about publication activity as a platform for discussing the nature and implications of concentration in leisure research at the individual and institutional levels. The study uses cluster analysis to detect patterns of research and publication activity among 1785 people who were associated with leisure research in North America in the 1990s, concentrating on the slightly smaller number of people (1631) whose names were listed as authors on at least one publication in all editions of 6 research journals and 14 conference proceedings from 1990 to 1999 inclusive. The results demonstrate that leisure research in North America is concentrated at both the individual scholar and institutional levels. For example, at the individual level, less than one-fifth of authors accounted for more than two-thirds of journal articles and conference papers. The implications of these findings are discussed with reference to issues such as the critical mass of scholars and problems of disciplinary isolation detected by previous researchers.
