基于地理学对"三江源"生态难民形成机制的分析

本文围绕“三江源”日益恶化的生态环境及由此引发的生态难民问题,从地理学的角度进行了综合分析,明确提出独特的自然环境系统和现代环境的变迁给源区牧民提供了极其狭小的空间,而人类活动中传统的生产方式、现代价值取向的变化、社会管理的失误以及落后的经济发展水平,无限制的对自然的索取,超越了环境系统所能承受的阀值,人类不得不听任自然的“安排”。因此,应通过合理规划,积极妥善地安置源区生态难民;调整产业结构,积极发展源区经济;科学管理,有计划地节制外来流动人员;发展教育,构建与源区生态相适宜的生态文化,实现区域可持续发展的“双赢”目标。     

企业风险传导及其载体研究

本文在概述风险与企业风险的基础上定义了何为企业风险传导,并对企业风险的传导路径作了归纳和分析;阐述了在企业风险的传导链和传导网络中,载体是风险传导过程中风险各要素相互联系的桥梁,也是各要素相互作用实现的有效形式;还揭示了在整个风险传导过程中,载体具有承载风险和传导风险的作用,同时,风险源、驱动力以及风险载体之间相互作用形成的耦合效应也使载体在企业风险传导链中具有“放大镜”的效应;并从企业风险传导的角度探讨了如何防范和控制企业风险。     

动态网页制作及ASP技术应用

ASP作为目前一种比较成熟的服务器端脚本编写环境,在网页制作中得到广泛的应用。ASP结合ADO能快速地实现对数据库的访问。本文介绍了ASP同数据库建立连接的两种方法,一种是通过OLE DB连接ODBC驱动程序,在ODBC的系统DSN中指定数据源进行连接;另一种是通过快速的OLE DB Provider技术连接数据库;同时介绍了动态网页分页功能的实现方法,增强了页面的可视化效果,实现了页面间的快速跳转,方便查询。     

Celebrity endorsements: Investigating the interactive effects of internalization,identification and product type on consumers’ attitudes and intentions

In line with Kang and Herr's work (2006), this research questions the ELM's contention that celebrity credibility serves foremost as a peripheral element in a persuasive communication context. Nevertheless, in a different light to the Kang and Herr's ‘either-central-or-peripheral-role’ of a source characteristic, this research advances that celebrity credibility plays concomitantly central and peripheral roles in a persuasive message context depending on product involvement and brand-purchase motive. Particularly, this research uses the notions of ‘source internalization’ and ‘source identification’ (Kelman, 1961) to theorize that source credibility can have a concomitant dual role (peripheral and central) in a persuasion context. More precisely, this research investigates the interactive effects of source identification and internalization with product involvement as well as brand-purchase motives on consumers' attitudes and intentions. Source internalization is predicted to have persuasive effects in the contexts of high-involvement as well as informational products. Source identification is predicted to have persuasive effects in the context of low-involvement as well as transformational products. The findings of two experiments show that celebrity credibility acts through only a single route (i.e., only internalization has persuasive effects) uniformly across different product involvement levels and brand-purchase motive types. We interpret these results with the lens of the ‘match-up’ hypothesis (Kamins, 1990).     

北京跨界水源地生态可持续发展模式比较研究——以官厅水库流域延庆怀来两县为例

水资源短缺和水环境污染的现状使得北京跨界水源地发展模式受到各界的关注。以官厅水库流域的北京市延庆县和河北省怀来县为例,运用指标体系进行对比分析,得出了延庆县符合生态可持续的发展模式,其生态可持续发展水平也接近或达到相关标准;而相对而言,怀来县的发展模式和发展现状距离生态可持续的目标差距较大。而行政区划是导致北京跨界水源地境内外发展模式不同的重要原因。     

A Welcome Revolution in Innovation

This review considers a major new book on von Hippel’s concept of user innovation. Von Hippel’s work has led to a welcome revolution in the economics of innovation. When producers are the innovators, there is an important difference in the interests of innovators and users. This can lead to dysfunctional innovation, especially in mature markets that are monopolised. In contrast, when users innovate, there are no such problems, as the innovator and the user are the same. User innovation can help enhance the power of innovation in wealth creation, and this edited collection helps to establish user innovation as a fully fledged field of the economics of innovation.     

Effect of diversification on capital structure

Previous empirical financial studies have paid little attention to the role of diversification strategy on financial choices. This study analyses the financing strategies of multibusiness firms, suggesting the relevance of sorting the diversification phenomena into its related and unrelated components. The implications of our findings are important because they explain earlier contradictory results on capital‐structure determinants and offer an explanation of how the degree of product specialization/diversification and the direction of diversification (related or unrelated) translate into different corporate financial behaviours.     

中国高额外汇储备的决定机制及可持续性研究

本文通过构建理论分析框架,分析外汇储备可持续性的决定机制和影响因素,选择我国相关数据和变量,建立了VAR模型并进行实证检验,刻画各因素与外汇储备之间的相关性,分解各因素对外汇储备规模的贡献度,从而识别决定外汇储备的短期和长期因素。研究表明出口导向机制、长期利益分享机制和短期套利机制是决定外汇储备规模的三大机制。在决定我国高额外汇储备持续性的因素中,出口是直接的、短期的因素,外商直接投资和人民币汇率是长期的决定因素,而人民币利率既是长期因素又是短期因素。外汇储备规模短期内仍将保持较高的水平,但从长期看,随着我国经济增长方式的转变和套利空间的缩小,经常项目和资本金融项目的双顺差会减少,相应的外汇储备也会下降。因此,在当前的外汇储备管理中,应稳定外汇储备的来源和质量,实现保值增值目标,并充分发挥其维护金融安全的作用。
