党的三代领导人对现代化的探索、实践和创新

中国共产党人对社会主义现代化的认识在探索和实践中不断深化.以毛泽东为核心的第一代领导人的艰辛探索,为中国特色的社会主义现代化事业奠定了基础;以邓小平为核心的第二代领导人围绕"什么是社会主义,怎样建设社会主义"这一基本问题进行实践,成功地把中国特色社会主义现代化事业推向了高潮;以江泽民为核心的第三代领导人,面临时代的机遇和挑战,与时俱进,开创了中国特色社会主义现代化事业的新局面.今天以胡锦涛同志为总书记的新一届党中央,继承发展着邓小平理论和"三个代表"重要思想,正在把中国特色社会主义现代化事业推向新的阶段.     

Understanding the distinctiveness of Chinese Post-80s tourists through an exploration of their formative experiences

Chinese Post-80s (the Chinese equivalent of Generation Y) are a distinct generation that emerged during a period of rapid political, social and economic change under Deng Xiaoping’s policy exploration with capitalism. Chinese Post-80s demonstrate higher levels of both complexity and sophistication in their tourist behaviours when compared with earlier generations of Chinese tourists yet their distinctiveness has been largely ignored in tourism research. Underpinned by generational cohort theory, this study explores the formative experiences of Chinese Post-80s and provides insights into the way these experiences have shaped this generation and their outbound travel. These formative experiences include Reform and Open Policy, One Child Policy and Education Reforms. Two discrete groups: “made in China” and transnational Chinese Post-80s tourists have been identified. We argue that while Chinese Post-80s tourists may share many aspects in common with their Western counterparts, this generation presents its distinctiveness due to its emergence from a specific sets of events with China’s rapid change that make Chinese Post-80s different from any generation in the global environment, creating new academic inquiries for established theories of generational studies. This nuanced understanding of Chinese Post-80s tourists has profound implications for theory and practice in the context of Chinese outbound travel.     

Evaluation of land-use and transport network effects on cyclists' route choices in the Copenhagen Region in value-of-distance space

Growing interest in sustainable transportation systems has driven decision-makers toward policies and investments aimed at promoting cycling, but little to no effort has been made toward incorporating bicycle transport in transport planning models. This study contributes toward this direction by estimating a bicycle route choice model in value-of-distance space from a large sample of 3384 cycling trips that were traced with GPS devices in the Copenhagen Region. The novelty of this study lies in (i) observing cyclists' behavior in a cycling-oriented country, (ii) exploiting rich data about the cycling environment, (iii) estimating the model in value-of-distance rather than preference space, and (iv) not focusing only on preferences for traditional variables (e.g., distance, turns, hilliness, intersections, motorized road characteristics), but also on perceptions and preferences for bicycle facilities (e.g., bicycle lanes, bicycle paths, bicycle traces) and land-use designations (e.g., residential, industrial, sports, scenic areas). The findings from the model show that: (i) cyclists exhibit heterogeneous preferences for avoiding right and left turns, cycling the wrong way, using roundabouts and bridges, and cycling alongside residential and scenic areas; (ii) cyclists dislike cycling on unpaved and hilly surfaces and alongside larger roads; (iii) cyclists have clear perceptions about different types of bicycle facilities, with a preference for bicycle lanes and segregated paths; (iv) cyclists have clear perceptions about land-use designations, with a preference for cycling alongside sports and scenic areas; (v) time-of-day and air temperature contribute to the perceptions of cyclists and their preferences for bicycle facilities and land-use designations.     

消费者决策型态的产品信号组合解构

消费决策型态体现了消费者的决策个性,是消费者识别和选购商品的一般心理定位,而信息经济学认为消费者与企业之间形成委托-代理关系,产品信号对消费者认知价值具有重要作用。不同决策个性的消费者对产品信号组合的反应不同,数据显示:完美主义、忠诚习惯、新潮时尚、决策依赖和品牌认知五种消费者决策型态与组合态下的产品质量、价格、功能、品牌、款式等信号存在显著关系。

新生代农民工身份认同困境分析

新生代民工身份认同的困境主要包括身份分类的矛盾和未来归属的矛盾两个方面。新生代农民工产生身份认同困境主要存在个人身份建构与社会建构之间的矛盾。社会距离是导致其自我认同困境的直接原因。相对剥夺感是导致自我认同困境的重要原因。追求生存目标与现有体制之间的矛盾是导致身份认同困境的根本原因。要解决新生代农民工的身份认同的困境问题,必须从内部条件、外部环境和政策建构等多个层面着手。     

风险识别与商业银行资本充足率监管

借助信号博弈模型,对资本充足率监管下监管当局和商业银行的行为选择进行的研究发现：在分离均衡条件下,资本充足率监管最有效;在准分离均衡条件下监管效果次之;在混同均衡条件下,监管效果最差。对资本充足率监管有效性的实证分析发现：资本充足率监管标准不仅对商业银行的资本管理具有实质性影响,而且对商业银行的经营思想、经营模式和经营机制产生了深远影响。
