竞争优势理论及其对我国服务贸易的启示

国家竞争优势理论是当前流行的国际贸易理论学说,该理论对一国制定服务业发展战略和提升国际服务贸易竞争力具有重要的借鉴意义。本文从国家竞争优势理论出发,在对我国服务贸易现状进行分析的基础上,提出以服务贸易国际竞争力为导向的若干对策建议。     

Conceptual underpinnings for transformative research in a service ecosystems context to resolve social issues – framework foundations and extensions

ABSTRACT

A number of services within society are designed to improve the well-being of its members and transform lives. Some services focus on the protection and support of vulnerable members of society, for example, those suffering the effects of drug use, mental health conditions, violence or poverty. Clients of such social services may also come from minority or marginalised cultural backgrounds. Typically, social services aim to reduce disparities and enhance individual and population well-being. A major challenge for social policy-makers and social service providers is to establish and maintain constructive engagement between the social services and those they are intended to serve. Some of these vulnerable clients are deemed ‘hard-to-reach’ (HTR) by policy-makers and service providers. Yet, the transformation of lives requires the involvement of the focal actor (client) and their service or activity system, as well as the engagement of other actors, such as the social worker embedded in their service or activity system. This paper aims to further unpack a novel approach, called integrative transformative service framework. This contribution extends its conceptualisation which fuses mainly three different approaches, namely Transformative Service Research (TSR), (Cultural-Historical) Activity Theory (CHAT) and (Regulatory) Engagement Theory (RET).

Emotional arousal and entrepreneurial outcomes: Combining qualitative methods to elaborate theory

This qualitative study of innovators in the superyacht industry blends longitudinal content analysis with narrative case vignettes to extend nascent theorizing about the antecedents and consequences associated with the arousal of entrepreneurial emotion. The empirically grounded framework induced through our research offers two key theoretical elaborations. First, it extends the existing set of theorized antecedents by highlighting the overlooked roles played by dramatic performances (staged or improvised) and ambient conditions (project, actor and venue considerations). Second, it calls attention to the consequences of emotional arousal for such entrepreneurial outcomes as generating novel solutions to specific problems encountered during the creation process, developing innovative end products, and fostering a general context for innovation.

企业异质性与服务贸易保护水平的决定——基于中国数据的实证检验

笔者从政治经济学的分析视角,运用博弈论的分析方法,对企业异质性和服务贸易保护水平的相关性进行了理论分析,并结合中国服务部门的数据进行实证检验。结果表明:一个服务部门的产业集中度越高,劳动生产率越低,资本密集度越低,其贸易保护水平也越高。此外,中国所有制结构的特殊性赋予企业异质性更多的内涵,在一个服务部门内,国有企业的比重越大,贸易保护水平也越高。     

How category characteristics affect the number of store brands offered by the retailer: a model and empirical analysis

Our research examines why retailers offer, not one, but multiple store brands in some product categories. More specifically, we are interested in how certain product category characteristics affect the number of store brands. We model a product category consisting of two incumbent national brands that may differ in strength. The retailer may introduce one or two store brands depending on which maximizes category profits. Our analysis suggests that the retailer is likely to carry two store brands in categories where (i) the national brands are similar in strength; and (ii) the price sensitivity between the national brands is low. Interestingly, the conditions that support the introduction of more than one store brand are quite different than the conditions that would facilitate the introduction of additional national brands. We provide empirical evidence that support our model-based predictions.
