With the rapid development of network economy and information technology, customers through the internet platform to participate in product development and innovation, dominant the spread of value proposition engagement spread, etc., has become an important part of the creation of customer assets, as well as a profound change in brand management. This paper constructs a model of how the brand experience affects customer assets in the virtual branding community under the perspective of value co-creation, analysis the impact of value co-creation of customer participation (sponsored value co-creation and autonomous value co-creation), the motivation of value co-creation on brand experience, and then on customer assets. This paper also explores the regulatory effect of value proposition engagement in brand experience and customer asset. This study will use the involvement theory and the theory of stimulus-response for empirical research, and through the questionnaire survey of consumers, using SPSS20.0 and AMOS20.0 statistical software on the relevance of relevant variables to grasp, and carries on the analysis using structural equation model. The research of this paper will enrich the exposition and explanation of building a brand experience better through value co-creation in virtual brand community, and provide theoretical support and practical advice for the implementation and management of customer assets.

The market for luxury is changing with new competitors to the market, more modest growth, and new types of customers (Kim and Ko 2012, Ko, Phau and Aiello 2016) as well as the ubiquity of digital marketing channels (Okonkwo 2009). Moreover, social media has transformed the logic of fashion marketing by providing new ways of engaging, interacting, and connecting with customers (Dhaoui 2014) as well as enabling consumers to participate in branding process (Burman 2010). As a consequence, also luxury brands need to develop experience-based marketing strategies that emphasise interactivity, connectivity and creativity (Atwal and Williams 2009). What is more, despite of growing importance of social media marketing in luxury industry, extant research on the topic still remains quite limited (Ko and Megehee 2012). While the previous studies have well documented the benefits of luxury marketing on social media (Kim and Ko 2012, Kim and Ko 2010, Brogi et al. 2013, Kontu and Vecchi 2014, Godey et al. 2016), and their implications on luxury brand management (Dhaoui 2014, Larraufie and Kourdoughli 2014), and even co-creative marketing practices (Choi, Ko and Kim 2016, Tynan, McKehnie, and Chuon 2010), no studies to this date have looked at co-creation from consumer-perspective. This article provides a novel perspective on luxury branding, by following the resource-based theory of consumer (Arnould, Price and Malshe 2006) to study the brand identity as co-created in social media. To do this, visual frame analysis (Goffman 1974, Luhtakallio 2013) is applied on consumer generated images downloaded from Instagram feed of brand exhibition staged by luxury brand Louis Vuitton. Based on the analysis, a typology of co-created brand identities is proposed. The findings indicate that in the branded exhibitions, consumers co-create brand identity by utilising resources available in the experiential brandscape by taking and posting these objectifications of brand on social media (Presi et al. 2016) and in so doing create symbolic/expressive, and experiential/hedonic value (Tynan et al. 2010). Theoretically, this article provides a novel perspective on luxury brand as co-created and in so doing, demonstrates the dynamics of firm-consumer co-creation. What is more, to extend the emerging stream of visual analysis of luxury (Kim et al. 2016, Freire 2014, Megehee and Spake 2012), an application of novel is demonstrated in the article. Managerially, this explorative study provides new insights on luxury marketing in social media by suggesting that branded experiences should be designed in a manner that engages the consumer to actively use the resources available to them. The financial implications of this shift are also significant as according to McKinsey study, three out of four luxury purchases are influenced by social media (Hope 2016)

This study (i) examines the main effect of how a customer’s trust in the service personnel could affect his/her service co-designing and co-delivering behavior; and (ii) investigates how the main effect could vary by the customer’s trust in the service brand, and the types of customer contact service contexts.

This paper examines the co-creation of human brands identities exemplified by celebrities in a stakeholder-actor approach. By bringing together the theoretical web of service-dominant logic, stakeholder theory, actor-network theory, and consumer culture theory, we argue that human brand identities are co-created by multiple stakeholder-actors that have resources and incentives in the activities that make a up an enterprise of a human brand, including the celebrities themselves, consumer-fans, and business entities. By utilizing an observational, archival netnographic data from popular social media channels, four exemplars of celebrity identities from the Philippines demonstrate the co-creation of human brands. Findings illustrate key stakeholder-actors’ participations, production and consumption, and integrations of resources and incentives in the co-creation process as articulated in social media. The co-creation process happens through sociological translations codes namely: social construction and negotiation of identities, parasocialization, influence projection, legitimization, and utilization of human brand identities. These dynamics of human brand identity advance a stakeholder-actor paradigm of service co-creation that is adaptive to the predominant consumer culture and human ideals that surround the celebrity. Implications and future research on celebrity brand marketing management are discussed.

Increasing attention has been paid to marketing and consumer behavior of luxury industry but research into value creation network and operational mechanisms is very limited. This study focuses on two aspects of the luxury industry: luxury brand and value chain, to inform a comprehensive understanding of the value creation process for high value added brands. In luxury industry, the key elements that create and deliver value are brand, design and research, production, distribution, and retail. A clear brand identity is found as the first step of this value chain, which influences the choices of all other activities. Luxury goods companies will align all the activities in line with brand identity to deliver consistent tangible and intangible values to end users. Furthermore, a luxury value chain is a holistic network with strong coordination among its elements. A combined approach of case study and secondary data collection is pursued. A sample of 9 luxury companies within 6 selected industries is investigated. Data is qualitatively collected via semi-structured interviews, document analysis, and observations as a triangulation approach for the purpose of ensuring the reliability of the research data. Multiple interviews of the general manager, industrial manager, brand/communication manager, creative director, and store manager are conducted in each company to achieve a broader perspective and also make data triangulation procedures possible. This research contributes to the luxury brands management as well as value chain concept. It discusses the value creation network and operational mechanism from a less explored corporate perspective. It unveils a secretive existence of brand in value generation process and further establishes a model to amplify the relationship between each activity in the value chain. Also, it expands the research of value chain into luxury industry. It argues that a supply leading value chain can also command a premium rather than the customer-centric value chain discussed by most researchers recently. It also provides valuable insights for companies who want to have a high-end market position. It shows that the widely adopted luxury strategy invented mainly by French and Italian companies employs fundamentally different rules from those of fast-moving consumer goods in mass market. In short, a luxury strategy is different in nature, not in level.

INTRODUCTION The term luxury usually defines not a category of products but a conceptual and symbolic set of dimensions. These dimensions comprise values that are strongly related to cultural elements and the wider socio-economic context (Vickers & Renand, 2003). Vickers and Renand (2003) recognised luxury goods as symbols of personal and social identity. Luxury is often used as a social marker, as a social stratification tool to reinforce a hierarchy (Okonkwo, 2010, Kapferer & Bastien, 2009). Due to the subjective nature of the luxury concepts and the complexity to define it, perceptions of luxury brands are not consistent across market segments and geographic locations (Phau & Prendergast, 2000), since they depend largely on each consumer's perception of indulgence. A common denominator between consumers in both Western and Eastern cultures is that the purchase of luxury brands serves to portray individuality and/or social standing (Nueno & Quelch, 1998; Vigneron & Johnson, 2004). Consumption of luxury brands is largely determined by social function attitudes (i.e. self-expression attitude and self-presentation attitude) as consumers express their individuality (e.g., need for uniqueness) and exhibits their social standing (e.g., self monitoring) through luxury brands (Wilcox et al., 2009). It is of growing importance for researchers and managers to understand how consumers' perceptions of value, influences buying criteria and behaviour (Tynan et al., 2010; Wiedmann, Hennigs, & Siebels, 2007). The perception of value by consumers is given a higher importance (Tynan et al., 2010) however the measurement of luxury value is not agreed amongst scholars and practitioners. Vigneron and Johnson (2004) proposed a structure of the luxury concept and presented the “brand luxury index” framework. Wiedmann et al. (2007) offered a conceptual model of luxury value perceptions highlighting four dimensions, namely: social, personal, functional, and financial values. Tynan et al. (2010) have adapted the earlier work by Smith and Colgate (2007) on generic value framework and suggested a conceptual model based on the following concepts: utilitarian, symbolic/ expressive, experiential/hedonic, relational, and cost/ sacrifice value. With the emergence of new concepts and levels of luxury, the measurement of value becomes even harder. According to Unity Marketing (2006) “…‘old luxury’ was about the attributes, qualities and features of the product and much of its appeal was derived from status and prestige. The new luxury consumer defines the category from their point of view. Today’s new luxury consumers focus on the experience of luxury embodied in the goods and services they buy, not in the ownership itself.” Robins and Ricca (2012) propose an alternative perspective on the established ‘new’ vs. ‘old’ luxury dichotomy. According to the authors, the more brands define themselves as belonging to the world of luxury, the more the concept becomes meaningless as luxury becomes ‘massified’. They introduce the concept of Meta-Luxury as a new form of luxury that escapes the cliché of luxury and establishes the “luxury beyond luxury”. In these complex scenarios, luxury brands are on a constant quest to remain relevant and maintain a sustainable competitive advantage. According to Beverland (2004) marketers now need to use “a complex combination of dedication to product quality, a strong set of values, tacit understanding of marketing, a focus on detail, and strategic emergence” in order to effectively manage luxury brands. With the recent focus on co-creation of value, luxury brand management has evolved to include dialogue and complex interactions between the brand owner, employee, customers and other social groups and communities (Tynan et al. 2010) making success factors harder to track. Purpose This paper aims to conceptualize a measurement tool that could be used in the evaluation and classification of a luxury brand’s performance and to assess how these dimensions evolve as the brand moves from mature towards more emerging luxury markets. This paper seeks to make a contribution, by providing a systematic review of the definitions of a luxury brand provided by various authors. It seeks to establish patterns and inconsistencies and to summarise them in a performance measurement matrix (the LPM framework) which can be used to identify growth strategies and to support future managerial developments. Design/methodology/approach The methodological approach followed in this paper was to systematically review the academic literature on luxury brands and to reduce the numerous factors cited as components and identifiers of luxury brands to a more manageable number of macro-themes. Through the analysis of the dimensions identified (with a further distinction between ‘new’ and ‘old’ luxury brands), the researchers intended to clarify the key elements of success that impact on brands competitiveness, leading to the definition of the items in the scale. In order to validate the elements, a survey was implemented to identify the most crucial indicators by building on the results of the systematic review. The aim of the survey was to clarify detailed criteria for each of the dimensions in order to construct an effective measurement scale. The scale was tested on four luxury brands selected amongst those perceived as ‘old’ / traditional luxury and ‘new’/emergent luxury. Findings Amongst academics and practitioners there is no common agreement or clear parameters that delineate what luxury is or the strategies such brands employ. This leads to confusion in the definition of the elements that constitute a luxury brand as well as in the brand management process. This paper proposes an alternative measurement scale to the Brand Luxury Index Scale developed by Vigneron and Johnson by focusing on a strategic overview of the performance of luxury brands in the UK market. It attempts to evaluate the performances of key luxury players by using a value-curve approach (Kim and Mauborgne, 2005) as a measurement tool. The value curve is a both a diagnostic and an action tool which captures the current state of play in the market space. The different constituents of the proposed Luxury Performance Matrix (LPM) should be considered when measuring the performance of a luxury brand and its capacity for value creation. The visual representation of the LPM model, allows marketers and brand managers to easily evaluate what aspects and strategic directions should be prioritized. It also allows to capture the brand’s performance across the key competitive factors of the industry and to determine which factors need to be raised above competition as way to increase competitiveness in the marketplace. The Luxury Performance Matrix proposed in this paper represents a major contribution to the measurement and evaluation of the competitive performances of established and ‘new’ luxury brands, in mature and emerging markets. Originality/value The proposed matrix will allow luxury brand managers to assess the current presence in the marketplace and develop more in-depth understanding of the brand’s performance. The findings provide valuable strategic insights for luxury brands operating across emerging and established product/market contexts.

This study was designed to investigate luxury brand co-value creation. A mixed method approach was used to 1) identify encounter attributes of value co-creation, consumer value and brand value and 2) examine the relationships among encounter attributes, consumer value, brand value, and purchase intention to explain the process of value co-creation.
