基于电子舌传感技术评价不同市售啤酒滋味品质

应用电子舌传感技术和多元统计学方法相结合的手段,本研究对市售6个啤酒品牌下15个样品的滋味品质特征进行综合评价分析。结果表明,评价啤酒品质的8种滋味指标可以划分为三大类,其中第一主成分由酸味、鲜味和鲜味的回味组成;第二主成分由苦味和苦味的回味组成;第三主成分由咸味、涩味和涩味的回味构成。因子分析发现综合得分排名前三的啤酒样品分别为C_1、F_1和E_1。与此同时,通过聚类分析可以将15个不同品牌与类型的啤酒样品按照滋味品质的差异情况分为5类,与现有啤酒市场行情相符。研究说明电子舌传感技术在啤酒品牌区分、品质口感判定和市场分析中具有巨大的应用潜力。     

How middle managers manage the political environment to achieve market goals: Insights from China's state‐owned enterprises

Research summary: Although the middle management literature has identified various bridging roles performed by middle managers in the market environment, it is relatively vague about whether and how they manage the political environment to achieve market‐related goals. In an inductive field study of four large state‐owned enterprises based in mainland Communist China, operational middle managers were found to take an active role in dealing with political actors to achieve market efficiency in their local environments, performing two distinct bridging strategies. Our field study suggests that middle managers are better equipped than their bosses (top executives) as well as their subordinates (frontline employees) to perform the bridging function between competing market and political imperatives in various local settings. Managerial summary: For firms that operate in diverse geographies, it is challenging for a handful of top executives to deal with numerous political actors. This burden could be shared with operational middle managers, who play a bridging role by drawing on their operational knowledge and local networks. Our research on middle managers who work under the scrutiny of political actors in China found that they bridge market and political ideology by conveying common features that seem legitimate to both. They also bridge market goals and political actors with personal affect. Compared to top executives and frontline employees, middle managers have unique advantages in performing these bridging functions. Firms can enhance their strategy execution ability by training middle managers in dealing with political actors in diverse contexts. Copyright © 2016 John Wiley & Sons, Ltd.     

“主体-技术”协同视角下的战略性新兴产业创新网络分类研究——以新能源汽车产业为例

本文以“主体-技术”协同视角来分析战略性新兴产业创新网络形成的内在机理和分类模式。在结合2-模网络理论基础上,从核心技术和创新主体两个维度出发,将战略性新兴产业创新网络分为单核心实验室型、单核心产业链型、单核心辅助型、单核心复合型、多核心实验室型、多核心产业链型、多核心辅助型和多核心复合型。同时,以中国新能源汽车产业为例,通过实证分析发现：除了单核心辅助型和多核心辅助型之外,其它6种模式均存在,并进一步对其创新网络的分类模式及相关特征进行了全面分析。     

Seeing relationships through the lens of psychological contracts: the structure of consumer service relationships

Serving as mental models, psychological contracts guide consumers’ service interactions with their service providers. This study incorporates a psychological contract perspective into the relationship marketing literature, exploring service customers’ beliefs about the terms and conditions of the resource exchange process and the types of relationships they form with service providers. It provides new insights that explain why and how some customers respond favorably to a company’s relationship overtures and investments while others do not. A latent class analysis on a sample of 700 consumers across three different service industries reveals that consumers form four distinct types of psychological contracts: relational, standard, transitional, and captive. To further validate the differences between the contract types, open-ended responses from the respondents were sorted by each class. The distinctive themes that emerged provide a richer understanding of the characteristics of each class beyond those inferred from the quantitative results. Each contract type is also profiled against its underlying level of trust, satisfaction, and commitment to understand the relationship between the contract types and these traditional relationship marketing variables. Marketers can differentiate their relationship marketing strategies and allocate their resource investments more effectively by segmenting consumers according to their psychological contract type.     

Mega-events as drivers of community participation in developing countries: The case of Shanghai World Expo

Within a wide body of literature it has been argued and demonstrated that community participation in tourism development is advantageous in terms of the sustainability and effectiveness of the development policies adopted. However, over time, doubts have been raised about whether community participation should take place in developing countries. There are major concerns regarding the immaturity and the incompliance of the political and social conditions of developing countries in relation to the requirements necessary for an effective participatory planning. In this paper, we argue that mega-events, due to their wide scope and the key role that large groups of stakeholders play in their success, may represent a driver for community participation in developing countries. In order to explore our idea, we will analyse tourism development and the planning of a mega-event within the Yangtze River Delta area, driven by the organisation and preparation of the Shanghai World Expo. According to our evidence, some initial elements of participative decision-making have indeed developed around the organisation of this mega-event, even though China has historically been considered refractory towards community participation. Finally, we discuss the findings in the light of existing knowledge to elicit significant questions about community participation in tourism development within developing countries and to address further research on this topic.     

基于能力贫困与权利贫困视角的我国城市贫困原因分析——以甘肃省为例

企业并购整合的超边际分析

企业并购作为一种资源的再配置过程,通常是指市场机制作用下企业为了获得其他企业的控制权而进行的产权交易活动。然而,现实中的企业并购大约一半最后都没有成功,统计资料显示,并购失败的主要原因在于企业并购后没能进行有效的整合。我国企业目前并购的形式主要是横向并购,那么同这种横向并购方式相对应,就更应该重视整合中并购企业之间的专业化协作问题。

数字经济对中国全要素生产率的影响机理:提升效应还是抑制效果？

数字经济是新时代引领中国经济高质量发展的关键抓手。然而现阶段数字经济普惠性发展尚未实现，掣肘着其对国内全要素生产率的提升力度。文章在理论分析的基础上，基于熵权TOPSIS法测算了2012-2018年中国数字经济发展水平指数，探讨了中国数字经济对全要素生产率的影响机理。研究发现：数字经济的发展显著提升了中国全要素生产率水平，但区域层面上，东部地区的数字经济发展明显领先于中西部地区，引领着中国全要素生产率快速增长。从全要素生产率的分解指标来看，数字经济推动了技术效率提升，但现阶段国内关键核心技术环节薄弱以及数字产业化带来的人才和资金的虹吸效应导致数字经济对技术进步产生了阻碍作用。此外，当前数字经济对不同产业的渗透度存在明显的不均衡性，筑高了创新资源的流动壁垒，影响产业间协调创新及合理化布局，进而抑制了对全要素生产率的提升力度。进一步的机制检验表明在创新环境的支持下，人才集聚及金融规模强化了数字经济对全要素生产率的提升力度。     

我国高速铁路对城市贸易发展的影响分析 ——基于对外开放程度不同城市的实证

高速铁路凭借其特有的技术经济特性成为影响城市贸易发展的重要驱动力,但其对城市进出口贸易有何影响及如何影响需进一步探索。通过对三个开放等级度56个城市的2006-2018年面板数据,运用双重差分模型(DID)进行实证研究,分析出高铁对城市贸易发展的影响情况。结论表明：高铁对开放程度较低城市的贸易发展有显著的促进作用;高铁对总体城市的贸易发展的影响并不显著;高铁主要是通过促进城市进口贸易的发展来提升城市贸易的整体水平。
