企业绿色营销的实施是一项复杂的系统工程,是可持续发展战略的必然要求。本文阐述了企业绿色营销体系,分析了阻碍我国企业建立绿色营销体系的因素,提出建立绿色营销体系的基本策略。     

Individual responses to firm failure: Appraisals,grief, and the influence of prior failure experience

This paper provides a systematic assessment of how entrepreneurs react to firm failure. We use appraisal theory as an overarching theoretical framework and hypothesize that the more the failure experience is appraised as stressful in terms of its implications for harm or loss, the greater the feelings of grief. To test this hypothesis we developed a unique database of entrepreneurs who recently filed for firm bankruptcy. Our results support that there is great variation in responses to firm failure, and we provide theoretically valid explanations to why this is the case. These findings have substantial implications for how scholars conceive and theorize about entrepreneurial failure.     

The double-edged sword: The positive and negative effects of switching costs on customer exit and revenge

What happens when customers have to deal with switching costs after a service failure and a poor recovery? This study seeks to address this question by proposing and testing an integrative model that incorporates customers' negative emotions as mediators between switching costs and behavioral outcomes (i.e., loyalty and revenge). The model distinguishes positive from negative switching costs, and inward from outward negative emotions. Analysis of survey data from 280 real customers who actually experienced a service failure and poor recovery with a major telecommunications firm reveals that customers react to switching costs strongly, emotionally, and sub-optimally. In contrast to most findings in the service literature, the results indicate that negative switching costs generate both exit and desire for revenge. Paradoxically, positive switching costs generate both loyalty and an even higher level of desire for revenge. These findings have important implications for the service industry.     

小蜂窝网络中基于速度估计的切换触发时间选择方案

在用户对系统带宽以及传输速率要求越来越严格的当下,小蜂窝技术成为解决室内和热点场景覆盖和容量问题的有效途径。为了缓解小蜂窝中切换失败率和乒乓切换率之间的矛盾,首先建立了小蜂窝网络场景下的切换模型,通过采用参考信号接收功率方案对用户终端（UE）的移动轨迹进行跟踪而达到速度估计的目的;之后,推导分析了该模型中切换失败概率、乒乓切换概率与切换触发时间、UE速度的关系;最后,采用遍历算法对切换触发时间进行优化选择。仿真结果表明,所提方案能够将切换失败概率降低到接近于零,同时将乒乓切换率降低了10%,很好地缓解了两者之间的矛盾,更适合于对乒乓切换敏感的高速移动UE。     

产业共性技术创新失败项目挽救对象甄选体系设计

产业共性技术创新的阶段性失败困境及潜在挽救价值使得失败挽救具有一定的必要性与可行性。然而,挽救实施前,需要界定挽救的技术范围、甄选挽救的潜在价值。为此,从技术范围与潜在价值两个层面,设计产业共性技术创新失败挽救对象甄选体系。首先,通过共性技术基因识别,刻画挽救的技术范围。其次,通过AHP-模糊灰色综合评价法结合价值评估体系,实现挽救的价值筛选。最后,基于生物医药行业实际案例,验证甄选体系的有效性,为挽救对象的有效选择提供实际应用方案。     

宏观审慎监管的基础：政策角度

2013年8月,世界银行经济学家奥古斯托·德拉·托尔（Augusto de la Torre）和阿兰·伊兹（Alain Ize）共同发表《宏观审慎监管的基础》（《The Foundations of Macroprudential Regulation》）。文章从政策的角度出发,研究把政府干预与市场失灵系统性联系起来的金融摩擦,并对宏观审慎监管的基础进行了详细分析。     

国有大型煤炭企业集团财务危机生成研究

从企业发展战略、内部资本配置及外部环境变化3个方面研究了国有大型煤炭企业集团财务危机生成的机制。研究发现,一方面国有大型煤炭企业集团对规模导向发展战略形成了路径依赖;另一方面,由于其内部资本市场的失效,资金配置于无效或低效资产,造成债务的积累和无效或低效资产的积累。当市场和金融等外部环境发生改变时,将极有可能爆发财务危机。最后提出了解决以上问题的相关政策建议。     

基于应变的X65悬空压力管道失效长度分析

根据Ramberg-Osgood关系式对X65管材的实验应力-应变曲线进行了研究及修正,得到了能准确描述X65管材应力应变的关系式,以便更准确地对管材的属性进行设置。给出了基于应变失效的关系式,通过Abaqus软件分别计算了以内压和壁厚为变量时,不同悬空长度下的管道模型,找出了悬空管道的安全失效长度和极限悬空长度。     

Public and private roles in plant health management

World-wide, government institutions play an important role in the management of plant health. This paper develops a conceptual framework in which suppliers and demanders jointly determine the optimal level of plant health in a hypothetical market. Next this paper argues that this market falls short of reaching an optimal plant health situation due to the public good nature of plant health and due to the presence of asymmetric information. A range of commonly applied and novel solutions to this market failure are then discussed.     

Determinants of Hazard Confronting New Entry: Does Financial Structure Matter?

This paper attempts to identify the determinants ofhazard confronting 219 new manufacturing firmsestablished in 1982–84 and followed up to1992 using a Cox regression model. Three sets ofvariables are combined in the analysis: firm, sectorand cohort specific. Financial, firm specificcharacteristics such as larger initial financialcapital size, conservative borrowing, heavier fixedasset commitment and lower diversification in terms ofholding other firms' assets are estimated to reducefirm hazard. Higher sectoral entry and lower sunk costsectoral requirements by increasing marketcontestability increase risk of failure together withcyclical variations.
