1. Introduction
Extensive literature compiled over the last 30 years has studied and highlighted the crucial significance of residents’ support when encouraging tourism developments [
1,
2,
3,
4,
5,
6]. The belief that “understanding residents’ perceptions and attitudes is fundamental to the successful and sustainable development of tourism activity” [
7] is the main reason for why we have witnessed increased research into residents’ attitudes towards tourism.
With the advance of the Internet, the holiday accommodation sector is undergoing a revolution [
8,
9]. Portals such as Airbnb, HomeAway, Home Exchange, or Couchsurfing have simplified and facilitated contact between hosts and guests so successfully that at the end of 2015, the number of beds advertised already exceeded the number of offers in traditional tourism establishments [
10,
11]. The magnitude of the phenomenon has led different authors to consider it as one of the main forces of change in the tourism sector, calling into question the traditional supremacy of conventional accommodation models [
12,
13].
However, the development of these new modalities of accommodation and their implementation in different destinations is neither stable nor without conflict, and this does not seem likely to change in the future [
14,
15]. In this sense, as well as the debate about the legitimacy and legality of this new world of exchange and the strong opposition from significant advocates for traditional business models, who accuse the portals of unfair competition [
10,
16,
17], conflict has arisen in some destinations between residents and tourists. In cities like Barcelona or Berlin, these incidents have led to loud demonstrations by citizens, who blame uncontrolled holiday accommodation for, among other things, overcrowding of the destination, increased rental prices, a lower quality of life, a deterioration in the coexistence of neighbouring citizens and local residents being forced to leave [
18]. Many of these negative arguments, especially in destinations with a higher incidence of holiday accommodation, have been widely published, both in the press and via other means of communication [
19].
Despite the constant increase in P2P holiday tourism, research related to the formation of residents’ attitudes towards this activity is extremely limited [
20]. To date, the majority has consisted of partial reports drawn up at the parties’ request [
10,
21] and particularly stresses the benefits or harm derived from the phenomenon, depending on how convenient it is for the interests of said parties. However, it does not analyse in depth why residents choose to support P2P holiday accommodation or not. Only recently have several attempts been made to create a model of how support is formed for this new tourism activity [
20]. These studies, using the Social Exchange Theory (SET) as a conceptual framework [
22], suggest that residents’ support largely depends on how they perceive the positive and negative impacts.
Understanding the variables that affect how residents perceive the impacts is one of the main challenges to be researched [
7]. This knowledge is extremely useful for managers of tourism destinations, as it enables them to design policies and regulations which aim to achieve a harmonious relationship between the different stakeholders at the destination (residents, tourists, administration, industry, etc.). This harmonious relationship is considered to be key for achieving sustainable tourism development [
2,
3,
23,
24,
25].
In this sense, one of the variables that have been suggested to be influential for residents’ perception of the impacts of tourism is the degree of knowledge that they have of said activity [
26,
27,
28]. This degree of knowledge is important on the whole, but in the specific case of P2P tourism, this variable seems to be even more relevant. The exponential growth of the activity, the conflicts in some cities, the large number of news reports related to the subject (normally negative), the pressure of lobby groups in the traditional accommodation sectors (normally against it) and, of course, the passing of time, have without a doubt multiplied the information that is available to residents on the activity and so have increased their knowledge. However, probably due to the fact that this phenomenon is quite new, there is no research that looks into its influence on the perception of the impacts generated by P2P holiday rentals. This research deficit can be added to the findings of several literature reviews [
7,
29], which point out the scarcity of research related to the formation of residents’ attitudes in top tourism destinations, meaning that it is not available to the destinations that would most benefit from such research.
To fill this void, this study analyses the influence exerted by broader knowledge of P2P holiday accommodation on perception of the impacts and on residents’ attitudes towards said activity. Using the SET as a theoretical framework, this study analyses the variation of the perception of the impacts and the support for holiday rentals in world-class tourism destination Majorca in two different years—2015 and 2017. Whereas in 2015, holiday rentals were starting to emerge and the degree of knowledge was slowly starting to grow, in 2017, measurements were taken within the context of greater knowledge of the activity. Mallorca is the largest island of the Balearic’s archipelago, one of the foremost mass tourism destinations in the world, welcoming more than 16.5 million tourists per year. Mallorca, inhabited by slightly 880,000 residents, hosts more than 11.5 million tourists per year [
30]. P2P vacational rentals offer in Mallorca is high; in 2017, a total number of vacational rentals published on platforms of 29,280 was estimated; this amount represents an estimated total number of 155,184 beds [
31]. The exposure of Mallorca residents to tourism and P2P vacational rentals gives them a privileged observatory for evaluating it.
The ultimate goal of this work is to increase the understanding of how residents’ support is formed towards P2P rentals, and more specifically, of the influence that residents’ “knowledge” of the activity exerts on their perception of the impacts and their attitudes towards it. Furthermore, the implications that can be derived from the results obtained in terms of destination management (management of potential conflicts, understanding regulatory decisions, etc.) will also be discussed.
3. The Influence of the Knowledge of Tourism on the Perception of Impacts
Many researchers have focused their studies on identifying, measuring and comparing the variables that can influence the way in which tourism and its impacts are perceived with the aim of explaining and potentially predicting residents’ responses to tourism. Sharpley [
7] carries out an extensive review of the factors analysed by the literature in this field and classifies them as intrinsic (related to the individual) and extrinsic (more related to the destination). Among the intrinsic factors, some recent studies have investigated the influence that the level of knowledge of the residents has on different aspects of the tourism activity. Knowledge refers to the residents’ understanding of the issues of tourism development, as well as the role of the government in their management.
In this context, Moscardo [
44] suggests that residents’ knowledge of tourism is an important aspect for the sustainability and good management of the sector. On the other hand, Cook et al. [
45] consider that in the structure of the social exchange theory, knowledge is an important resource for those involved, and it determines their position in a social exchange network.
The works that have studied the influence of residents’ knowledge of tourism on their attitudes towards the perceived impacts in the sector are inconclusive.
Residents with knowledge of tourism are more likely to recognise the benefits and costs of its development [
26]. Davis, Allen and Cosenza [
27] discovered that tourism “haters” included residents who generally had a poor knowledge of the subject. The study by Andereck et al. [
26] indicated that residents with knowledge of tourism were more likely to report positive impacts, whilst Nunkoo [
28] only reported a significant relationship between knowledge and the negative impacts perceived. Contrary to these findings, Látková and Vogt [
46] found that knowledge is an insignificant predictor of the positive and negative impacts.
The residents’ perception of the different impacts associated with the development of P2P accommodation is predicted to be affected differently if there is a greater knowledge of the activity, but until recently, this activity was not widely known by the general public. The growth of the activity, the large number of news reports related to the subject, the conflicts in some cities, the pressure from lobby groups, and the impacts of this activity have led residents at these tourism destinations to become more aware of the phenomenon in recent years. In this sense, based on the SET and the revised literature, the following hypotheses have been made relating to the influence of the perceived impacts and residents’ attitudes:
The perception of the benefits increases if there is a greater knowledge of the activity:
- -
H1a:The perception of the economic benefits of P2P holiday accommodation increases if there is a greater knowledge of the activity.
- -
H1b:The perception of the social benefits of P2P holiday accommodation increases if there is a greater knowledge of the activity.
- -
H1c:The perception of the cultural benefits of P2P holiday accommodation increases if there is a greater knowledge of the activity.
- -
H1d:The perception of the environmental benefits of P2P holiday accommodation increases if there is a greater knowledge of the activity.
The perception of the costs increases if there is a greater knowledge of the activity:
- -
H2a:The perception of the economic costs of P2P holiday accommodation increases if there is a greater knowledge of the activity.
- -
H2b:The perception of the social costs of P2P holiday accommodation increases if there is a greater knowledge of the activity.
- -
H2c:The perception of the cultural costs of P2P holiday accommodation increases if there is a greater knowledge of the activity.
- -
H2d:The perception of the environmental costs of P2P holiday accommodation increases if there is a greater knowledge of the activity.
- -
H3:The residents’ attitude towards the activity, according to the SET theory, will increase or decrease together with the level of knowledge, depending on whether the increase in the perception of the benefits is greater or lesser than the increase in the perception of the costs.
5. Results
5.1. Reliability and Validity of the Scale
Before performing the means difference analysis, it was deemed necessary to validate the measuring instrument. In terms of reliability, the results obtained (
Table 2) confirmed the individual reliability of each item. In all cases, the factor loads obtained were greater than 0.6, which is the reference value that is used normally [
55]. Likewise, the combined reliability was also checked, given that in all cases values greater than 0.8 were obtained, which is the strictest value required in basic research [
56].
The aim of the convergent validity analysis is to guarantee that the scales measure exactly the concept that is intended to be measured, instead of other factors that are external to the construct. Convergent validity exists when several measurement items used to evaluate the same concept correlate with each other [
57]. Evaluations are generally carried out by using the average variance extracted or AVE [
58] and Cronbach’s alpha [
56]. The AVE values and the Cronbach’s alpha coefficients obtained (
Table 2) were higher than 0.5 and 0.7 respectively in all cases, which served to confirm the convergent validity of the constructs, as they exceeded the reference values.
The discriminatory validity is the degree by which each latent variable is different from other constructs [
59]. In order to meet Fornell–Larcker’s criterion [
60], the square root of the AVE for each construct must be greater than all the correlations between the constructs and the other constructs. In addition, it must be verified that all of the constructs are related to a greater extent to their own measurements than to other constructs [
54]. Moreover, the heterotrait–monotrait (HTMT) [
61] has recently been established as a superior criterion for evaluating the discriminatory validity, which represents the average of heterotrait–heteromethod correlations relative to the average of monotrait-heteromethod correlations [
61]. In this study, the most demanding method of HTMT.90 has been used to evaluate the discriminatory validity [
61].
Table 3,
Table 4 and
Table 5 show the results of the evaluation of the discriminatory validity of the measurements according to Fornell–Larcker’s criteria, crossed loads and HTMT.90, respectively, and indicate that the constructs have discriminatory validity.
5.2. Descriptive Statistics
Table 6 contains the average scores of the items of the different constructs. As we can see, the attitude towards P2P accommodation was highly positive in all of the indicators, both in 2015 and 2017. The perceptions of the benefits of the activity were high in all of the dimensions, particularly in the economic and social dimensions. However, although it was still high, we could see less support for this type of accommodation in 2017 than in 2015. The perception of the economic impacts hardly varied between 2015 and 2017; however, we could see a smaller perception of the benefits and a greater perception of the costs in the social, cultural and environmental impacts.
5.3. Knowledge
This activity has been carried out exponentially over a period of very few years, and it has been subjected to widespread media attention, with constant news reports about its potential effects. This fact, together with greater experience or even use on the part of the residents, enables us to anticipate that, in the space of a few years, residents’ knowledge and criteria for evaluating the implications of the activity have increased.
In fact, in
Table 7, we could see the large increase in knowledge, for example of the P2P holiday accommodation reference platform Airbnb, which has gone from being known by 28.1% of the sample analysed in 2015 to 47.3% in 2017; that is, an increase of 68%.
Likewise, in
Table 7, we could see the increase in the experience as users (guests) of this platform, rising from 17.2% in 2015 to 23.0% in 2017 (increase of 34%).
5.4. Differences in the Perception of Impacts and Attitude
To find out the effect of “knowledge” on the residents’ attitude towards P2P holiday accommodation and on the perceived impacts in the two periods analysed, a means difference analysis (Student’s T-test) was carried out using as an independent variable the year, and as dependent variables, on the one hand, the construct “Support for the P2P holiday accommodation community” and, on the other hand, the constructs of the scale of perceived economic, social, cultural and environmental impacts, both on benefits and costs. The calculation was carried out in two ways: using the means of the construct items and taking the values of the latent variables (constructs) calculated based on the confirmatory factorial analysis.
Table 8 contains the results added from the Student’s
T-test for the analysis constructs, as well as the calculation of the increase in the value between 2015 and 2017.
As we can see in
Table 8, in general, the greater the knowledge of the activity, the more the perception of the benefits decreases and that of the costs increases. Consistent with that established by the social exchange theory, the support decreases.
Hypotheses H1a and H2a were not confirmed, that is, a greater knowledge of P2P holiday accommodation activity does not change the perceptions that the activity leads to high economic benefits and low costs.
Of the perceived impacts, the economic benefits were the highest, both in 2015 and 2017. The perception of the economic benefits and costs hardly varied between the two periods (−3% and +2% respectively).
The relationships proposed by hypotheses H1b, H1c and H1d were established, but in an opposite manner; that is, the residents’ perception of the social, cultural and environmental benefits decreased with a greater knowledge of the activity.
The perception of the social, cultural and environmental benefits diminished slightly, although significantly, between the two time periods (−6%, −7% and −7% respectively).
The relationships proposed by hypotheses H2b, H2c and H2d were confirmed; that is, the residents’ perception of the social, cultural and environmental costs increased with a greater knowledge of the activity.
The environmental costs were those with the greatest significant increase, rising from a mean of 2.78 to 3.28 (an 18% increase). There was also an obvious increase in the social costs, from a mean of 2.73 to 3.17 (a 16% increase). Although very low, the cultural costs also underwent a significant increase, from a mean of 2.52 to 2.81 (an 11% increase).
Hypothesis H3 was confirmed according to that set out by the SET theory; that is, support for P2P holiday accommodation decreases due to a perception of greater costs and fewer benefits.
The attitude towards P2P holiday accommodation was still highly favourable, although it decreased significantly (−8%) between 2015 and 2017.
6. Discussion
This study has focused on finding out the effect of knowledge on the residents’ attitude towards P2P holiday accommodation and the perceptions of the negative and positive impacts in the four dimensions (economic, social, cultural and environmental), as a fundamental key aspect for sustainability and effective management of the sector [
44].
It was possible to check the reliability and validity of the scale in order to measure the residents’ perception of the impacts and their attitudes towards P2P holiday rentals, contributing to the state-of-the-art scope of applications of the social exchange theory for new situations and activities in the tourism industry.
The increase in the degree of knowledge of the resident population regarding this activity is confirmed, derived from a greater use of this type of accommodation and probably the extensive publication of news in the media related to it.
Likewise, the study confirms the influence of a greater level of knowledge and awareness of the activity on the perception of the impacts and on attitudes.
The validity of the SET is confirmed, meaning that the lower the perception of benefits or the higher the costs, the lower the residents’ attitude towards the activity evaluated.
According to the results of the study, knowledge—referring to a greater understanding of the activity on the part of the residents—generally results in a greater perception of costs and a lesser impact of benefits, contrary to Látková and Vogt’s [
46] suggestion that knowledge is an insignificant predictor of the positive and negative impacts.
In this sense, the results concerning the perception of costs confirm the results of Andereck et al. [
26], Nunko [
62] and Davis et al. [
27], which show that greater knowledge on the part of the residents implies a perception of greater costs. However, in the part of this study concerning benefits, we have found that the greater the knowledge, the lesser the perception of benefits, which does not agree with that put forward by Andereck et al. [
26].
Furthermore, these results are coherent with that suggested by the social exchange theory, given that when there is an increase in the perception of the costs and a reduction in the perception of the benefits, this would imply less support towards the activity; a point which is confirmed. Therefore, this study ratifies the proposal of Cook et al. [
45] regarding the fact that knowledge is an important resource for those involved, and it determines their position in a social exchange network, making it an important construct in the SET.
In addition, the results of this research imply a series of implications for those responsible for destinations within the scope of management and regulation of the activity.
A greater understanding of the variables that affect the perception of the impacts will help tourism destination managers to take measures towards the appropriate management of the activity.
In this context, it has been possible to see how knowledge affects the perception of impacts and consequently attitudes towards P2P holiday accommodation. Destination managers would be able to carry out objective studies that evaluate the extent of the activity and its effects, and subsequently inform the population. The aim of this would be to provide more objective, impartial information. Information gathered by interested parties can bias the interpretation of the effects of the activity, and this may lead to rejection or acceptance that may have mid- and long-term effects in conflicts or unwanted situations with the local population. Therefore, it seems to be necessary for governments to develop suitable information systems that diffuse and explain the true characteristics, dimensions and impacts of this activity objectively. In this way, residents would be less influenced by any diffusion of data and information that aims to create certain opinions against or in favour of the activity. Transparency in management from those responsible is imposed as a criterion to be able to deal with new situations and challenges that are posed by the new forms of tourism activity and business models.
7. Limitations of the Study
The results of this research may be limited by contextual aspects that it would be necessary to evaluate in further studies.
Firstly, the analysis has only been carried out at one tourism destination, and it would need to be repeated to be able to generalise the theoretical results obtained. Furthermore, the study has been carried out at a destination where there have been no relevant conflicts with the residents.
The study makes a comparison at two moments in time between which a clear difference in knowledge has been noted, but there is an apparent stability in other aspects. However, other variables may exist that could affect the change of perceptions and knowledge.
In addition, the media pressure related to this activity in recent years may have caused subjective effects, and the increase in “knowledge” may not have been neutral or objective.
The comparison between 2015 and 2017 may be too close.
In this sense, researchers have opened new lines of research aimed at:
- -
To obtain data between longer periods of time
- -
Replicate the study elsewhere in order to be able to extend the results
- -
Analyse other possible variables to include in the change in perception of impacts and attitude towards P2P accommodation
