1 Introduction

Accommodation Sharing (AS) is one of the fastest growing branches in the sharing economy [1]. The information about houses (rooms) and hosts displayed on AS platforms is easy to get and be used by accommodation seekers. At the same time, users are able to post their reviews freely through these platforms. Thus, the form of word of mouth (WOM) has broken through the oral communication and has become an electronic word of mouth (eWOM) [2]. For experiential products such as hotels and restaurants, eWOM plays an important role in helping make better decision by reducing uncertainty [3]. Previous studies have proven that eWOM has a significant impact on consumers’ affirmative intentions [4]. However, research about eWOM in the context of AS has been limited, and the popularity of accommodation has not been paid attention compared to its practical importance. To fill in this gap, the purpose of this study is to explore the influence of different heuristic dimensions of eWOM (i.e., house, review, and host attributes) on accommodation popularity. Moreover, rental (i.e., entire vs. Shared houses) and host (i.e., individual vs. Merchant hosts) types are further considered moderating variables to see if those relationships are different according to these types. This research is one of the first attempts to explore the relationship between multi-dimensional heuristic factors of eWOM and accommodation popularity in an AS setting. It would provide hosts and AS platform managers with a depth of knowledge on how accommodation seekers’ preferences can be realized through eWOM.

2 Theoretical Background

2.1 Multi-dimensional Heuristic Attributes of eWOM in AS

eWOM is defined as all informal communications related to specific goods/services by consumers through the Internet [2]. According to [3], when individual’s motivation and ability level of information processing are relatively weak or the volume of information to be processed is too large, heuristic processing cues, rather than systematic ones, become dominant. By exploiting multi-dimensional heuristic cues of eWOM (i.e., house, host, and review attributes), users of AS platforms can reduce the cognitive burden when making decisions [5].

2.2 Accommodation Popularity

The popularity of accommodation refers to the state of being liked, satisfied, or re-purchased by a large number of consumers. There is a significant positive correlation between accommodation popularity and consumers’ reservation intention [4]. As prior research used online guest reviews as a performance measure of AS [6], the number of likes is used for measuring accommodation popularity in this study.

3 Research Model and Hypotheses Development

Based on literatures on eWOM and the sharing economy including AS, the research model is developed, which is shown in Fig. 1.

3.1 House Attributes

The content analysis of users’ perception of AS shows that the main factors are location, landlord, decoration, interactivity, and convenience, with the exception for price [7, 8]. Similarly, Tujia.com (the target AS platform of the study) offers a review scoring system (1–5 Points) with different key attributes of AS such as location, decoration, service, and cleanliness. As houses (rooms) with high scores are more attractive to (potential) guests, the following hypotheses are proposed:

  • H1: Distance score has a positive effect on accommodation popularity.

  • H2: Cleanliness score has a positive effect on accommodation popularity.

  • H3: Decoration score has a positive effect on accommodation popularity.

  • H4: Service score has a positive effect on accommodation popularity

3.2 Review Attributes

According to extant studies, the number of online user reviews has a positive impact on hotel room sales, vivid and intuitive pictures have a more positive effect on consumers’ purchasing decisions than abstract words, and negative reviews are easier to gain consumer trust than positive reviews [9]. Thus, the following hypotheses are posited:

  • H5: Number of reviews has a positive effect on accommodation popularity.

  • H6: Image reviews rate has a positive effect on accommodation popularity.

  • H7: Negative reviews rate has a negative effect on accommodation popularity.

3.3 Host Attributes

Sztompka (1999) [10] proposed three criteria for hosts to gain consumer trust: reputation (past behavior record), performance (actual behavior), and appearance (personal appearance). A high acceptance rate indicates that a host has good service capabilities or abilities to provide enough extra rooms, which helps increase the level of trust to the host and enhances the favorability of the accommodation [4]. The popular accommodation hosts have the characteristics of high rates in terms of praise, performance, response, and acceptance. Thus, the following hypotheses are suggested:

  • H8: Host’s praise rate has a positive effect on accommodation popularity.

  • H9: Host’s performanceH8: Host’s praise rate has a positive effect on accommodation popularity.

  • H10: Host’s response rate has a positive effect on accommodation popularity.

  • H11: Host’s acceptance rate has a positive effect on accommodation popularity

3.4 Moderating Role of Rental Type and Host Type

The AS occupancy rate can be different according to the rental type as consumers who want to try an entire house put more importance on privacy, while guests who choose to live with a host emphasize the experience of living within the local atmosphere [11]. In the same vein, individual hosts are more popular with consumers who want to live like a local, although merchant hosts can provide more professional services to them. Therefore, the following moderating hypotheses regarding the rental (i.e., entire vs. Shared houses) and host (i.e., individual vs. Merchant hosts) types are proposed:

H12a ~ d: The effects of house attributes (distance, cleanliness, decoration, and service scores) on accommodation popularity are different according to the rental type (entire vs. Shared houses).

H13a ~ d: The effects of host attributes (praise, performance, response, and acceptance rates) on accommodation popularity are different according to the host type (individual vs. Merchant hosts).

4 Research Methodology

This study will employ the data crawling technique to measure variables used in the research model. Accommodations listed on Tujia.com (China’s largest AS platform) located in the four tier-one cities in China will be chosen as the target area of data collection. The illustrative sample accommodation on Tujia.com with all variables used in the analysis is presented in Fig. 2.

5 Expected Contributions

This study is one of the first attempts to explore the relationship between heuristic factors of eWOM and accommodation popularity in the AS context. Moreover, it identifies multi-dimensional heuristic features of eWOM, and examines their impacts on accommodation popularity, expanding the concept of eWOM with a single heuristic dimension into the eWOM with three different heuristic dimensions including house-, review-, and host-related attributes. It would provide valuable insights for AS platform managers and hosts in understanding how accommodation seekers’ preferences can be realized through eWOM.
