2.1. Live Streaming Servicescape
Live streaming refers to the e-commerce activities in which the streamer (merchant or manager) provides consumers with product display and purchase services through product trial and experience sharing in an online live streaming room[
8].
Live streaming e-commerce has gained wide attention due to its high-level interaction and unique content presentation and has gradually become an important means of product marketing[
9]
. Zhang, Chao [
10]revealed that environmental stimuli of live streaming have a significant positive effect on consumers’ intentions to make in-store purchases. P
ositive effects of live streaming exist on customer engagement and impulse buying[
11]
. Furthermore, Zhang, Qin [
12] confirmed that the influence of live streaming based on different product types on the purchase intention of the audience is significantly different. Shih, Silalahi [
13]reveal the essential role of socio-technical systems in developing trust, highlighting the emergence of trust in streamers as a crucial factor in extending trust to the products promoted. According Xu, Cao [
14] research, the constructed multimodal reputation signals of live streaming’a anchors can effect on product sales prediction. By virtue of anchors' professionalism and interactivity, they can significantly influence the shopping intention of the live streaming audience[
15].
Bitner [
16] first proposed servicescape theory which can explain the total influence of the various elements involved for the study of live streaming. In the SOR model based on environmental psychology, the servicescape is the stimulus (S), whose main aim is to attract consumers’ reactions, such as attention, purchase intention, or encourage impulse buying, and to cause their evaluation (O) [
17]. The SOR theoretical model has also frequently been used in studies to understand online consumer behavior. There are generally two types of research on the stimulus response of servicescapes. The first focuses on the influence of the overall servicescape framework; the second focuses on the stimulus response of specific elements in the servicescape. For consumers on any shopping trip, various displays in the servicescape in a physical store have differential impacts on their purchase incidence and brand choice behavior [
18]. Kawaf and Tagg [
19] proposed that words, pictures and music in an online shopping environment can significantly affect consumers' emotions and cognition. Hongxia, Zhihui [
20] proposed that online commodity displays enable consumers to obtain better virtual tactile experiences and increase their desire to buy. Zhani, Mouri [
21]Zhani, Mouri [
21]Zhani, Mouri [
21] have found that the dimensions of the m-servicescape (i.e., aesthetic appeal, perceived security, and layout and functionality) generate mobile value (i.e., hedonic and utilitarian), which in turn leads to user purchase intention.
H1. The live streaming servicescape has significant positive effects on purchase intention regardless of whether consumers have experience purchasing luxury goods.
According to Bitner [
16] opinion, the various physical factors are carefully designed and controlled by service places, including environmental conditions, layouts, signs, symbols and artifacts. Furthermore, social factors have been brought into the research category. Scholars have studied the impact of the social elements of servicescapes on consumers’ behavior, such as interpersonal social interaction and social density [22, 23]. Following the development of internet technology, the e-servicescape emphasizes technical factors, and researchers have proposed that the servicescape includes three aspects: aesthetic appeal, functional layout and financial security. Financial security refers to the ease of use and security of online technology [
5]. Against this background, and combining the characteristics of servicescape theory and live streaming technology, in this study, the evaluation index of live streaming servicescape can be divided into three dimensions: physical factors, social factors and technical factors. Hence, according to the SOR framework, consumers perceive these three factors of the live streaming servicescape, have joyful emotions and experiences, and, finally, generate their purchase intention.
In luxury stores, social intimidation is key to maintaining the exclusivity and desirability of their brands. Facing the opulence and magnificence of such stores, consumers question their own status and evaluate their social fit. They feel more or less legitimate depending on their economic capital (wealth) and/or cultural capital (tastes and practices developed through education and experience). This perception of social inferiority creates social intimidation and exclusion. Therefore, two kinds of consumers may flood into the live streaming room with luxury goods: consumers with or without experience purchasing luxury goods. However, it is difficult to create this kind of social intimidation and exclusion in a live streaming room with luxury goods. That is, physical factors cannot exert different influences on these two kinds of consumers:
H1a: The purchase intentions of consumers with experience purchasing luxury goods are more likely to be influenced by the physical factors of live streamers than those of consumers without such experience.
Due to the difference in luxury purchasing experience, there are the different understandings of luxury culture among these two kinds of consumers, they have different demands for luxury goods in a live streaming room. The elite use luxury goods as a sign of distinction and an affirmation of their status because luxury reflects social stratification and exclusive privilege. Xin and Hong [
24] pointed out that social interaction in online shopping could enhance consumers' sense of social presence, thus affecting their purchase intention and behavior. Hence, we propose that the purchase intention of consumers with experience purchasing luxury goods is more influenced by the social factors of live streaming than that of consumers without such experience. According to the SOR framework, when consumers are stimulated by social factors, they enhance their involvement and interactivity, whereby their purchase intention is further stimulated:
H1b: The purchase intention of consumers with experience purchasing luxury goods is more likely to be influenced by (b) social factors than that of consumers without such experience.
Harris and Goode [
5] emphasized that factors including the ease of technology application and website security can significantly affect consumers' purchase intention. For example,
IT affordances in live streaming indirectly affect customer engagement through swift guanxi and perceived enjoyment[
25]. According to the SOR framework, consumers are stimulated by perceived technical factors, which enhance their perceived safety and reliability and thus their purchasing intention. Therefore, the influence of live streaming servicescape factors differs among these two types of consumers. We formally hypothesize the following:
H1c: The purchase intention of consumers with experience purchasing luxury goods is less likely to be influenced by (c) technical factors than consumers without such experience.
2.2. The mediating Effect of Consumer Trust
Among consumers with experience purchasing luxury goods, we posit that trust is a mechanism that explains their differential increase in purchase intention by the live streaming servicescape. Consumer trust is defined as consumers’ belief in a firm’s ability and competence to perform a specific task under specific circumstances[26, 27]. Consumer trust is produced amid commodity transactions and is endowed with richer connotations in the e-commerce environment. In the field of consumption, trust mainly refers to consumers' perceived security and reliability of transactions. The connotation of trust is also related to a trading situation where the trustor is experiencing risk or uncertainty [
28]. In short, trust is a decisive factor that affects whether consumers make purchases on a website and is usually used to express their willingness to perceive safety or take risks.
Various factors in the live streaming servicescape have a significant impact on consumer trust. Harris and Goode [
5] proposed that consumer trust is not only key to the online physical environment but also its core. Xin and Hong [
24] mentioned that social interaction in online shopping can enhance consumers' social presence, thereby affecting consumer trust, risk and safety perception. Yu, Xing [
29] pointed out that trust is affected by the security of network technology and that consumers' recognition of technology security strongly affects consumer trust. In e-commerce, consumer trust is regarded as an important antecedent variable for online transactions or even a necessary condition for transactions [
5]). Yu, Xing [
29] also verified that consumer trust significantly positively affects consumer purchase intentions in online retail. Harris and Goode [
5] introduced consumer trust as an intermediary variable between online servicescape and purchase intention. Shih, Silalahi [
13] pointed out that the design of online servicescapes affects consumer trust and that consumer trust significantly affects consumers’ willingness to purchase goods online.
Consumers with experience purchasing luxury goods have knowledge about the focal product and luxury brand according to ELT. Based on ELT, knowledge “is created through the transformation of experience”, and “knowledge results from the combination of grasping and transforming experience” [
30]. Experiential learning therefore plays a role in the impact of deep/offline purchase on customer value [
31]. Since most luxury brands originate from developed nations, they might possess a desirability value that provides consumers a signaled value that goes beyond the functional aspects of the focal product [
32]. These contemporary meanings and attributes reflected by luxury’s signaled value help consumers elevate their understanding of the symbolic world [
33]. Luxury brands aim to create value and enhance allure by increasing the experiential attributes that are symbolic and hedonic in nature [
34].Luxury goods may also lead to the enhancement of a consumer’s identity and self-worth [
35]. Accordingly, since consumers in the modern era relate luxury to experiences and feelings [
36], those with experience purchasing luxury items gain knowledge of luxury goods. A luxury store involves a kind of traditional transaction that allows customers to feel more security and reliability than the novel transaction channel of a live streaming room. Because the new retailing channel enhances the visibility of both genuine and counterfeit consumption of luxury brands, which also bring the anxiety and psychosocial risk[
37]. Therefore, when they enter a live streaming room, customers pay attention to the security and reliability of transactions within it. Conversely, customers without experience purchasing luxury goods in these contexts care more about the perceived value of luxury goods. Accordingly, trust is the primary mediator for consumers with experience purchasing luxury goods, whereby the following hypothesis is proposed:
H2. Consumer trust plays a more significant intermediary role between the live streaming servicescape and purchase intention among consumers with experience purchasing luxury goods than those without it.
2.3. Perceived Value of Luxury Goods as the Mediator
Perceived value, a key influencing factor for how consumers evaluate goods or perceive service quality, significantly affects their willingness to purchase. Bowman and Navissi [
38]found that in the virtual online shopping environment, consumers' behavioral decisions are obviously affected by their perceived value. Zhou and Huang [
15] also found that online consumers’ perceived value has a significant impact on their purchase intention. Regarding the physical factors of the live streaming servicescape, Man, Qin-Hai [
39] pointed out that music and color have a significant impact on consumers' perceptions and emotions and other psychological benefits. Baker, Grewal [
22] proposed that consumers perceive goods and services through the physical factors in a store. In terms of social factors, Pozharliev, Verbeke [
40] confirmed in a product browsing experiment that it is easier to stimulate consumers' perceived value of luxury goods when they are accompanied by others. For luxury goods, whose price is typically much higher than their use value, scholars have primarily assessed their social-oriented values, such as their conspicuous value [
41], unique value or conformity value [
42]. With the improvement of living standards, the perception of luxury goods has gradually encompassed individual-oriented values, such as self-pleasure, self-gift, inner self-consistency and quality assurance [
43]. Luxury consumption has thus become more subject to personal emotional experience and feeling value.
Hence,Vigneron and Johnson [
44] have developed the brand luxury index, which includes social value (significance, uniqueness and quality) and personal value (hedonism and self-extension). Amid the deepening of this research, four dimensions of luxury value perception have also been gradually developed: individual value, social value, functional value and financial value [
45]. Perceived luxury value has also become more multifaceted. Jiang and Shan [
46] proposed that the functional value, hedonic value and social value of luxury goods have a positive impact on luxury purchase intention. Jain [
47] showed that the perceived value of luxury goods, e.g., conspicuous value, experiential value or utilitarian value, have a significant impact on consumers' purchase intention. Nevertheless, while these scholars have conducted salient research, the mediating role of the perceived value of luxury goods still lacks any clear verification. Among consumers without this kind of experience, their purchase intention for luxury goods in live streaming is driven by their perceived value thereof. Thus, the following hypothesis is proposed:
H3: The impact of the live streaming servicescape on purchase intention is mediated by the perceived value of luxury goods among consumers without experience purchasing luxury goods but not among consumers with such experience.
2.4. Moderating Role of Conspicuous Consumption
Veblen and Chase [
41] was the first to define conspicuous consumption. He believed that with the increasing abundance of life, members of the leisure class increasingly prefer to display their social status. They thus obtain social prestige and status recognition by conspicuously purchasing expensive goods. Sivanathan and Pettit [
48] put forward the intrinsic motivation of conspicuous consumption, i.e., consumers promote self-perception, enhance self-esteem, and promote the construction and improvement of their self-concept through conspicuous consumption. These results show that conspicuous consumption is also derived from both social-oriented and individual-oriented motivations. Research has also found that groups with lower living standards allocate a higher expense proportion to conspicuous consumption [
49] and that consumers across all social classes have a conspicuous consumption motivation. Moreover, interpersonal influence can promote conspicuous consumption. In the live streaming servicescape, social factors such as live streamers and other spectators form the reference group of consumers. Marcoux, Filiatrault [
50] also mentioned that interpersonal interaction is an important dimension of conspicuous consumption. Therefore, the live streaming servicescape interacts with the conspicuous consumption motivation, and they can influence one another.
Ling, Nan [
51] pointed out that consumers with a conspicuous consumption motivation are more willing to boast of their identity and status through luxury goods and that the perceived value of luxury goods is more intense. Moreover, according to Amaldoss and Jain [
52], the perceived rarity of luxury goods can significantly affect consumers' willingness to purchase such conspicuous products. Pozharliev, Verbeke [
40] proposed that the presence of other people lead to a higher stimulation of consumers' value and a higher probability of consumers' purchasing willingness for boasting reasons. More specificly, there are two kinds of motivation, an intrinsic motivation to enjoy privacy in luxury consumption and an extrinsic motivation of being associated with the experienced luxury elite[
53]. Accordingly, the current study posits that conspicuous consumption regulates the relationship between live streaming servicescape and perceived value of luxury goods, as well as between live streaming servicescape and consumer purchase intention. The following hypothesis is thus proposed:
H4: Conspicuous consumption serially moderates the effects of live streaming servicescape on the perceived value of luxury goods and purchase intention.
