西藏高原县域尺度农业绿色发展水平综合评价——以白朗县为例

[目的]推进农业绿色发展是实现农业可持续发展的有效途径,为客观了解西藏高原农业绿色发展水平,探讨农业绿色发展的驱动因素,为高原农业绿色发展研究提供参考。[方法]文章以白朗县为典型县域案例,从农业生产、农业资源、农业环境、农业生态和农民生活五方面,选取17个指标系统构建评价体系,采用层次分析法确定评价指标的权重值,基于统计数据、遥感数据和调研数据评价2016—2020年白朗县农业绿色发展水平,并利用两阶段最小二乘法分析影响农业绿色发展水平的驱动因素。[结果]（1）2016—2020年白朗县农业绿色发展水平总体呈现上升趋势,由2016年的0.102 7提高到了2020年的0.233 9,增长约2.28倍。其中,农业生产、农业环境和农民生活水平逐年提升,但农业资源水平2018年后却持续下降。（2）多元回归模型分析驱动因素表明农林水事务性支出与农业绿色发展水平存在显著的负效应（P<0.001）,随着农林水事务性支出的降低,农业绿色发展水平会提高。[结论]白朗县农业绿色发展水平整体呈现良好的发展态势,农业生产和农民生活方面贡献较大,但农业资源方面仍是绿色发展的短板,因此今后白朗县农业绿色发...     

人民币汇率弹性的增大对利率稳定性的影响

汇率改革前后,汇率与利率之间的动态关系发生了系统性的改变。在均值意义上讲,人民币汇率弹性的增大降低了利率波动的幅度,利率对汇率的反馈机制有了一定的加强。实证检验证明,汇率改革后人民币汇率弹性的增大能稳定利率波动的假设只在长期内存在,而短期内人民币弹性的增大实际上加剧了利率的波动。     

技术进步引起国际贸易摩擦的一个模型

保罗·萨缪尔逊在2004年提出的国际贸易模型中,运用数字例子对国际贸易的互利与摩擦问题进行了分析。文章运用一般化的数学方法,扩展了这种研究,在四种和N种商品的贸易模式中,对国际贸易的互利与摩擦问题做了进一步的分析。国际贸易的互利与摩擦依赖于某种技术进步导致的贸易商品数目的变动,并在国际贸易的比较优势的区域内,依据一定的条件形成,并相互转化。     

Co-Evolution: Law and Institutions in International Ethics Research

Despite the importance of the co-evolution approach in various branches of research, such as strategy, organisation theory, complexity, population ecology, technology and innovation (Lewin et al., 1999; March, 1991), co-evolution has been relatively neglected in international business and ethics research (Madhok and Phene, 2001). The purpose of this article is to show how co-evolution theory provides a theoretical framework within which some issues of ethics research are addressed. Our analysis is in the context of the contrasts between business systems (North, 1990), and in particular the distinction between informal systems and those systems where institutions are formalised in law. This complements the growing research on comparative corporate governance and capitalisms (Chandler and Hikino, 1990; Choi et al., 1999; Whitley, 1994). The synthesis of co-evolution and analysis of divergent institutional environments in ethics research can also complement the globalisation and MNE approaches to international business research.     

Retail bank selection in developed and developing countries: A cross‐national study of students' bank‐selection criteria

This exploratory research article is concerned with students' selection of retail banks in the United States and Ghana. It is a comparative cross‐national study aimed at revealing the factors determining retail bank selection among students in different environmental settings. The key objective is to establish if there are any significant differences and/or similarities in students' selection of retail banks in developed and developing economies. A similar data‐collection method was employed in the United States and Ghana to facilitate constructive comparison. The results identified four key factors—convenience, competence, recommendation by parents, and free banking and/or no bank charges—to be consistent across the two economies. The recommendation of the study is that in the context of an open and liberalized market environment, retail bank marketing strategies should be standardized irrespective of the national development stage. It concludes that retail bank managers particularly in developing countries should learn to provide consistent and good customer care. © 2009 Wiley Periodicals, Inc.     

The effects of sales promotion strategy,product appeal and consumer traits on reminder impulse buying behaviour

This article investigates factors of marketing communications and consumer characteristics that induce reminder impulse buying behaviour. Study 1 applies the antecedent, process and consequence approach to investigate the essential differences between reminder impulse buying and pure impulse buying. The results of Study 1 reveal that reminder impulse buying significantly differs from pure impulse buying on motivation, buying goal and decision evaluation. Study 2 further examines how sales promotion strategy might affect reminder impulse buying, with product appeal and consumer traits as moderating factors. Both sales promotion strategy and its interaction effects with product appeal are found to have significant influences on reminder impulse buying. Specifically, an instant‐reward promotion promotes stronger reminder impulse buying than a delayed‐reward promotion. Furthermore, both a utilitarian product appeal with a price discount promotion and a hedonic product appeal with a premium promotion can encourage greater reminder impulse buying.

世界经济体制性失效及对中国经济的诊断

在世界市场通货膨胀、通货紧缩和资产价值崩溃等现象的背后,是市场经济体制性失效。资源性商品价格会因为投机性活动的失范和泛滥而暴涨暴跌。因此在世界范围内,当前应当着手的不是仅仅调节供求,更不是供求力量双方相互指责,而是为如何克服世界市场经济的体制性失效,克服美国等发达国家为了自身的眼前利益而利用这种体制性失效,放任美元市场、借贷市场、证券市场、期货市场等虚拟经济部门中垄断力量的盲目扩张和操纵市场造成的困难,从而为建立一个更为完善的世界市场经济体制而共同努力。     

主流西方经济学思维对流通理论与实践的影响

以马克思主义为基础的流通理论在建立市场经济过程中发挥了重要作用,但当其随着流通产业的发展进入了新的阶段后,却面临着发展的困惑,就其理论根源而言,是因为主流西方经济学将精力集中在不影响私有产权基础上的制度设计和机制研究,加之理论发展上的路径依赖,对于竞争性的流通领域进行理论研究不符合其理论传统和研究路径.理论上的滞后导致流通产业实践过程中隐含危机,因此流通理论虽不是主流西方经济学的研究范畴,但产业发展和变化要求我们循序渐进的进行流通理论的创新,使其符合时代的需要.
