Intertemporal Equity and Hartwick's Rule in an Exhaustible Resource Model*

In a standard exhaustible resource model, it is known that if, along a competitive path, investment in the augmentable capital good equals the rents on the exhaustible resource (known as Hartwick's rule), then the path is equitable in the sense that the consumption level is constant over time. In this paper, we show the converse of this result: if a competitive path is equitable, then it must satisfy Hartwick's rule.     

专业化管理的家族企业——新加坡的华人企业

通过考察大量口迷历史记录、个人访谈、文献研究及有关新加坡经济、社会的评论，研究了亚洲金融危机（以下简称危机）前后新加坡华人企业变化及其发展的持续性，表明危机前，这些大型企业由家族制管理变为专业化管理；危机后，其变化趋势有两种，一种由于面临着西方企业日益激烈的竞争，在政府密切关注下，同时也因缺乏有能力、有管理家族企业意愿的后代，家族制度已松散；另一种由于没有政府的直接管制，在危机后消极的市场形势下，为谋求生存，任用有能力的家族后代充分发挥优势，维持着传统的家族制。本文分别从市场、制度（包括文化和政府）及一些主要大公司的领导者行为分析，推导一个路径清晰、条脉分明的管理变化模式，同时提出进一步的研究方向——专业化管理家族企业的结构及政府的角色。     

中国经济真的动态无效吗

史永东与杜两省、史永东与齐鹰飞、袁志刚与何樟勇相继考察了中国经济的动态效率,结果均表明中国经济是动态无效的.本文首先通过实证研究进一步检验上述结论,并进而追问中国经济为什么会发生动态无效.笔者的分析表明,这种无效性只是一种表象,它是由我国的粗放式经济增长方式决定的,其根源在于静态资源配置,特别是投资配置的无效性.在此基础上,本文进而指出,上述作者提出的消除无效性的政策建议是不恰当的,真正有效的途径只有转变增长方式,提高增长绩效.

影响农村和谐的因素及其法治对策

农村民主政治不健全、经济文化落后、法律制度不完善、社会矛盾激化是影响农村和谐的主要因素。构建农村和谐,必须加强农村法治,用法治来健全农村民主政治,发展农村经济文化,完善农村法律制度,化解农村社会矛盾。     

试析法治路径的悖论

中国法治的路径选择存在着悖论性问题.以一种语境化的分析方法,在对"自治"与"他治"、"政府主导"与"民主参与"、"确定"与"不确定性"三组范畴的比对中,辨析法治路径的悖论性内容,借以补正与完善法治路径选择中的某些理论问题.     

Exploring the use of travel information – identifying contextual market segmentation in Seoul, Korea

As the amount of information is rapidly growing, and ubiquitous urban environments are emerging, the question which kind of information to provide is a major challenge for commercial and public travel-information service providers alike. This paper reports the analyses of recent data, collected in Metropolitan Seoul, about the acquisition of travel information. The study applies CHAID analysis to find homogeneous segments in travel information acquisition. Findings indicate that contextual variables are crucial to explain information acquisition behaviour, depending on decision context. The implication is that both socioeconomic and contextual variables are important to better understand the acquisition (and provision) of travel information. The results have important implications for managers and policy-makers, in particular in the way they respond to dynamic, contextual market segmentation.     

Economic development lessons from and for North American Indian economies*

This paper reviews the literature on economic development as it relates to indigenous people in the United States and Canada, and focuses on how institutions affect economic development of reservation and reserve economies. Evidence shows that strong property rights to reservation and reserve land and natural resources, whether communal or individual, are and always have been important determinants of productivity. Political and legal institutions that are perceived as stable and predictable to tribal members and to non‐Natives also improve economic opportunities for indigenous people living on reservations and reserves. Research reviewed here also shows that culture and acculturation are important in the development process. Although our emphasis is on North America, the findings are applicable to indigenous people in other parts of the world and shed light on growth questions that loom large for developing countries around the world.     

基于动态贝叶斯网络的邻近下穿隧道深基坑施工风险分析

为了减小邻近既有下穿隧道深基坑施工风险及灾害损失,科学预防施工安全事故,提出了一种基于动态贝叶斯网络（DBN）的深基坑施工风险分析模型。首先,运用BWM（best worst method）确定准则的权重;其次,基于关联规则挖掘风险因素间的相互关系,并以此构建DBN结构模型;最后,以新建厦门北站地下一层社会连廊深基坑工程为例,对提出的方法进行有效性和适用性检验。结果表明：基坑围护结构的安全度在静态被评为“较高”和“极高”的概率分别为34.6%和36.1%,且此结果随着输入风险证据发生动态变化,运用反向推理也能迅速找出围护桩渗水风险;提出的模型能明确邻近既有下穿隧道深基坑施工风险传递过程中的关键风险点,并能进行动态风险预测以及事故后致因诊断,从而实现邻近既有下穿隧道深基坑施工风险的动态管控。所提出的优化DBN模型对工前风险评估、先验分析和风险诊断有较好的适用性和较高的准确性,可为邻近既有隧道深基坑施工过程中的安全管控提供有效的决策支持,大幅提高风险控制效率。
