“双二元短缺约束”下中国经济的阶段性特征

2005年以后,中国结束了长达50多年的短缺经济,进入产能过剩与资源约束为主的新短缺经济阶段,主要体现为＂生产资料与生活资料生产能力双过剩＂和＂资源性生产要素与基础设施、公共服务供给双短缺＂并存。1978年改革开放以后,中国经济经历了一个从短缺经济——后短缺经济——新短缺经济的演化过程。第一,1978-1996年,短缺经济阶段,主要表现为生产资料和生活资料的双短缺;第二,1996-2005年,后短缺阶段,主要表现为生活资料基本过剩,而生产资料存在短缺和不足;第三,2005年以后,新短缺经济阶段,主要表现为生产资料和生活资料的＂双过剩＂,资源约束与市场约束＂双约束＂逐渐成为我国经济发展的主要制约性因素。     

城乡一体化的理论渊源及其嬗变轨迹考察

运用历史分析法,以时间为经,以理论为纬,对城乡一体化的理论渊源及其嬗变轨迹进行了系统考察。结果表明:有关城乡联系的早期论述是城乡一体化的理论渊源,马克思恩格斯的城乡融合思想将其推向了一个新的高度,而由二元结构理论衍生的城乡偏向发展观却使城乡联系理论难以为继,可它又在一定程度上为其回归奠定了坚实基础,并使之更加深入发展,从而促成了今天关于城乡一体化的热烈探讨。最后,基于当前中国城乡关系的复杂性和特殊性,从理论和实践两个方面指出城乡一体化理论研究对推进中国城乡一体化进程的启示意义。     

Welfare Effects of Technological Convergence in Processed Food Industries

We develop a monopolistic competition model to investigate effects of international technological convergence on factor rewards, output composition, and welfare. Comparative static analysis indicates technological convergence improves the follower's—but impairs the leader's—international competitiveness. The leader's welfare improves unambiguously; the follower's welfare depends on the relative strength of convergence's income and terms-of-trade effects. We use data from seventeen food industries in thirty countries, 1993–2001, to test these analytical predictions. Evidence of convergence is found in thirteen of seventeen industries. Convergence lifts followers' relative wages and global value-added shares. Followers benefit from convergence's positive income effect. Leaders benefit from higher terms of trade.     

资本资产定价模型（CAPM）应用问题研究

资本资产定价模型使投资组合理论在整个经济学领域得到广泛的应用,但理论与实际背离的情况经常发生。他们研究发现其原因就是模型基本假设与经济环境的不符,并通过比较分析给出控制应用风险,改善投资环境的种种建议。

微波带状线低通滤波器的设计制作与性能改善

讨论了带状线低通滤波器因实际制作的导带宽度发生变化引起滤波器性能下降时,如何改善滤波器性能的方法。我们采用惠普公司ＥＥＳＯＦ软件,对滤波器的结构和电气参数和分别作了灵敏度分析,以此为改善滤波器性能的依据。经实验对比,改进后的滤波器性能有了明显改善,且性能稳定。     

Chinese tourists' views of nature and natural landscape interpretation: a generational perspective

This study investigates Chinese tourists’ views of nature, interest in animal experiences and their preferred natural landscape interpretation content from a generational perspective. Eight hundred and eight self-administered questionnaires were collected at Wulingyuan, a UNESCO World Natural Heritage Site, in China. It suggests that overall Chinese traditional cultural values and beliefs, notably the thinking of tian ren he yi (oneness of nature with humans), still have considerable impacts on Chinese tourists. They were found to have a strong sense of connection with nature and a preference for cultural interpretations of natural landscapes. Meanwhile, Chinese might be reaching a point of convergence in terms of attitude towards nature and animals with their Western counterparts, as reflected by their weak anthropocentric view, and strong ethical and aesthetic appreciation of animals, regardless of generation cohorts. Yet, the study shows significant generational gaps: older generations have a stronger connection with nature, are more concerned about environmental issues and show more support for the Western approach towards nature protection; the younger generations hold weaker anthropocentrism, and are more interested in animals, yet are less likely to learn about nature through tourism interpretation.     

Examining the efficacy of self-classification approach in segmenting special-interest tourists: food tourism case

Self-classification is used as an a priori approach to tourist typology and market segmentation. However, skepticism still surrounds its ability to incorporate the multidimensionality of tourist behavior. This study seeks to empirically verify the efficacy of a single-item self-classification approach. The robustness of this self-classification measure is examined by comparing it to a data-driven multidimensional psychographic approach in terms of its ability to predict the behaviors of tourists toward food-related destination consumption. Results suggest that the single-item self-classification approach performs equally well as the psychographic approach in segmenting food-related consumption behaviors. The implications and limitations of this study are also discussed.     

新生的旅游地:灾后重建背景下的地方重构——以四川省彭州市白鹿镇为例

灾害发生和灾后重建过程中,地方在短时间内经历着急剧的解构和重构,发生了巨大的改变.然而,当前灾后重建影响研究聚焦于重建对弱势群体的影响,在灾后重建对地方的社会、文化和经济影响方面缺乏相应的探讨;现有社会文化地理研究对灾害与地方话题亦缺少必要的关注.研究以四川省彭州市白鹿镇为案例,通过访谈法,借用地理学“地方”的理论对灾后重建的影响进行分析,以此透视灾后重建背景下的地方重构过程,探寻灾后重建影响下的地方形态、功能、活动和意义的变化.研究表明,白鹿镇的地方重构特征主要体现在公共空间的升级、生活空间的变革、地方产业的转型、地方生活的转变,以及地方特性的重构和地方情感的强化等方面.灾后重建背景下白鹿镇的地方重构实质上是旅游景观、旅游活动和旅游形象对原有乡村景观、活动和形象进行替代的城镇化和现代化过程.“地震”某种程度上成为白鹿镇发展的“契机”,借助灾后重建资本和政策的支持,白鹿镇实现了地方的“新生”,不仅修复了地震带来的破坏,还突破了原有的土地和景观问题以及地方发展的资金局限,实现了地方的转型、升级和发展.
