中国证券业效率的动态分析

本文利用DEA和基于DEA的Malmquist生产率指数,运用32家主要证券公司的相关数据,对中国证券业2004至2006年间的技术效率进行了分析和评价。结果显示,中国证券业的整体效率水平尽管还比较低,但已经显示出了不断提高的趋势;证券公司效率的两极分化趋势已初露端倪;越来越多的证券公司开始出现规模报酬递减;技术变化对生产率变化的影响超过了效率变化,成为生产率变化的主要原因。     

兵团农户借贷行为特征与制约因素研究

随着中国农村金融体制改革的进一步推进和深化,农村金融供给制度越来越倾向于农户这一微观需求主体福利水平的提高,不同的金融供给制度安排必然会产生不同的借贷行为。本文以新疆生产建设兵团农户借贷状况调查为基础,分析兵团特殊金融供给制度下农户借贷行为特征,剖析农户借贷行为的制约因素,揭示兵团农业经济发展与农村金融体制之间矛盾,并提出相应的政策建议。     

Roadmap for interactive exploration of sustainable development opportunities: The use of simple instruments in the complex setting of bottom-up processes in rural areas

Before embarking on the development of rural areas or regions it seems necessary to answer the following key questions: what goals of the parties involved can be realized, and where, when and how? To tackle these questions we have developed a ‘roadmap’, as part of an overall sustainable development procedure for physical planning and spatial management in rural areas. The roadmap is a tool for the process manager and the people involved. It helps to find the way in the exploration of the potential social, economic and ecological benefits of developing the area or region. The purpose of using the roadmap is to alleviate doubts about the advantages of cooperating in pursuit of sustainable development. A back-casting approach is applied to create appealing visions of the future and visualize mutual opportunities worth implementing. In this article we first describe the need for this new roadmap. We then describe its use, step by step and in some detail. An example of the exploration process is described and the strengths and weaknesses of the roadmap are discussed.     

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。     

区域旅游一体化进程中边界效应的定量化研究——以长江三角洲地区入境旅游为例

本文首先分析了边界效应的两种形式,即质的边界效应和量的边界效应,并构建了区域旅游一体化进程中对行政区边界效应的度量方法.以长江三角洲地区为例,以1991～2006年为样本区间,对其入境旅游发展做了实证研究,探讨江苏与浙江、上海与江苏、上海与浙江之间的边界效应.通过邹检验(Chow Test)发现,长江三角洲各城市间的经济水平存在结构性的差异,进一步的回归检验结果表明,长江三角洲各城市间存在一体化的趋势,但存在着量的边界效应.进而考察了长三角边界效应的演化情况,结果表明江苏和浙江之间的边界效应从有到无,上海与江苏的边界效应、上海和浙江之间的边界效应存在增大的趋势,并且上海与江苏的边界效应增大的速度明显地高于上海和浙江之间的边界效应增大的速度.最后.本文从旅游资源条件、经济条件、交通条件、直辖市作用、制度条件5个方面对演化的原因进行了解释.     

An Indirect Test of Children's Influence on Efficiencies in Parental Consumer Behavior

A statistical test is applied to explore the possibility that children can affect the efficiency with which parents consume. Parents may receive some economic benefits from children in the form of reverse integenerational transfers that occur because of a positive influence children have on family behavior. Results show that not only do children have an influence on parental consumption, but also that the influence is beneficial. In fact, not accounting for such a benefit could cause an underestimate in such measures as the rate of return to education or the benefits from such governmental programs as Head Start.     

Higher skilled working tourists and their leisure lifestyles: a qualitative study of guest language instructors in South Korea

Using interviews conducted with 24 higher skilled working tourists employed as guest language instructors in the Republic of Korea, this paper explores how working tourists could secure an optimal leisure lifestyle in their host countries. Three key findings emerged. First, the respondents were seeking casual, touristic, amateur, hobby and volunteer leisure with their colleagues and with their host community members. But, the rewards and episodic aspects of their leisure, including formal and informal language development, suggested that it incorporated variations in project-based leisure as a core characteristic. Second, these respondents were taking part in guest, host and leisure speech communities that were each offering leisure choices. However, their leisure lifestyle was best when leisure, second language development and acculturation coincided in a leisure speech community. Third, that in a leisure speech community, respondents’ acculturation and friendships improved more so than in either guest or host speech communities. Also, that these respondents’ formal and informal second language learning within their leisure speech communities was essential for an optimal leisure lifestyle. The paper determines that leisure speech communities, occurring along a continuum of monetary, educational and interpersonal resources, could affect the linguistic mobility of higher skilled working tourists. It recommends that future research could examine if a sociolinguistics of leisure could assist in exploring and mapping the leisure lifestyles appearing among mobile populations in a globalising world.
