An Effect Of Management Service Quality On Residential Satisfaction And Recommended Intention Of High-Rise Apartments

Recently, a lot of high-rise apartments are being built around large cities in the world. The highrise apartments are a valuable living space for residents and are located in the center of the city, providing a distinctive and advanced residents' convenience while maintaining a high price of real estate along with the landmark role. In this background this study examined the relationship between the evaluation of the quality of management services perceived by residents and the satisfaction and recommendation intention of tenants living in high-rise apartments in China. This study empirically examines the relationship between the quality of management services (environmental quality, process quality, result quality), satisfaction and recommendation intention of tenants living in ‘high-rise apartments’ in large cities in China. The results showed that the quality of management services of high-rise apartments had a significant effect on residential satisfaction and recommended intention. In addition, among the quality of management service affecting residential satisfaction and recommendation intention, the relationship was the highest in the order of process quality (β=.363, t=5.362), result quality (β=.306, t=5.610), and environmental quality (β=.200, t=3.319). Therefore, in order to enhance the satisfaction of the residents of high-rise apartments and to induce positive attitudes and follow-up actions, it is necessary to pay attention to the needs of the residents and deal with them promptly and kindly, rather than the physical environmental quality of the high-rise apartments and the quality improvement efforts shown in the research results. Therefore, in order to enhance the satisfaction of the residents of high-rise apartments and to induce positive attitudes and follow-up actions, it is necessary to pay attention to the needs of the residents and deal with them promptly and kindly, rather than the physical environmental quality of the high-rise apartments and the quality improvement efforts shown in the research results. It can be said to be an important implication confirmed through this study.

INTRODUCTION
In the 1990s, the use of high-rise buildings in China was mainly used for business and commercial functions, but recently it has been developed for complex uses such as hotels and apartments due to economic and functional considerations. High-rise residential complex apartments that have recently been built in the metropolitan area within China are precious residential spaces for residents, not only offering differentiated and advanced convenience but also maintaining somewhat higher price of properties.
Especially as the entire society is being converted into service-centered economy and its subsequent competition mounts, even in the case of building maintenance, demand for some advanced service has increased. Accordingly, the necessity for policies in the field of building maintenance emerged that improve the quality of property maintenance service and increase customers' satisfaction on all kinds of management services. Despite of such practical necessity, however, the empirical study as to the management service of high-rise residential complex apartment is not very active.
In this perspective, although a systemic, scientific study is necessary in terms of microcosmic dimensions on management service of high-rise residential complex apartment, the existing precedents related are extremely limited in that they focused on functional and technological characteristics, related law, and location such as floor plan, not on residents' practical satisfaction on the structure. Besides, it is true that some research on residential satisfaction lacks approaches to the concepts such as service quality. ^R eceived: Reviewed: Accepted: * Corresponding Author Hence this study has the purpose of making an academic basis of providing more comfortable and convenient residential environment through consumer-centered housing supply in high-rise residential complex apartments by evaluating the quality of management service of residents in high-rise residential complex apartment in China and investigating residents' satisfaction and recommendation intention in the apartment.
This study investigates the characteristics of consumer choice behavior by surveying residents of high-rise residential complex in the Chinese metropolitan area and examines their attitudes, experiences and cognitive behaviors about the management service of high-rise residential complex, with which this study examines residents' satisfaction and recommendation intention on the complex through the aspects of residential use.
This study ushers in the examination of various literature not only domestically but globally and extends its focus on the pursuit of theoretical bases on characteristics of service, degree of satisfaction and recommendation intent by looking up the existing materials. Moreover, it comprises the three elements on the quality of the management service: environment quality, process quality and result quality. Additionally, it analyzes the influence and relationship between the variables in terms of the correlation of variables leading to recommendation intention.

HIGH-RISE BUILDING
The history of high-rise building beginning from the late 19th century spans around 100 years to the end of the 20th century. On account that the term 'high-rise' implies a little relative concept, it cannot be reduced to a uniform definition [1]. In other words, buildings regarded as high or high-rise ones may be considered ordinary. Furthermore, a single definition of the height of the kind can be relative, making the buildings seen differently according to states, cities, and scholars studying in the area.
Today, the commonly used standard to indicate whether a building is high-rise or not is based on the definitions of CTBUH-Council on Tal Buildings and Urban Habitat. According to the standard, high-rise building is defined as a building having a height of 20m or more or 50 stories or more, or a ratio of the bottom and height of 1:5 or more, and one determined by existence of lateral load resistance system. High-rise architecture in the modern sense is considered as a type which has been needed based on the logic of economy or capital, and can be analyzed as a type that develops with the modern technology such as elevator and structural engineering improved. The standards for high-rise buildings can be set up by relative standards in accordance with the era, region, culture, and social differences rather than simply their absolute height [2]. the building in which the number of stories is 50 or more or height is 200m or more the building over 60 meters high 1)the building over 50 stories or over 20 meters high 2)underside-heighted ratio is 1:5 or greater 3)the existence of lateral load resistance system

THE STATUS OF HIGH-RISE BUILDINGS IN CHINA
Thanks to the rapid growth of urbanized population, China has been building world-class buildings more than any other country on the planet. As of 2018, China has 3,867 high-rise buildings that meet the definition of Chinese Building Act. There are 2,575 buildings over 100m in height, 1,862 buildings over 150m, 678 buildings over 200m, and 68 buildings over 300m. Among these, buildings over 150m account for much more than any other country in the world. In 2018, China built 88 high-rise buildings with more than 200 meters high, making itself become the first in the world, followed by the United States which built 13 buildings. However, the number of high-rise buildings over 100m built by China in 2018 is overwhelmingly over six times more than the US. That accounts for 61. Due to the boom of construction in China, the number of skyscrapers worldwide has nearly tripled over the past decade with more than 1,000 new skyscrapers added since the global financial crisis in 2008. The reason why China builds a large number of high-rise buildings is that China's economic growth is first cited, followed by the increase in GDP, expansion of domestic market, and population inflow into cities. And the combination of performanceism and institutional factors inside China can be another reason for the increase of high-rise buildings.

QUALITY OF MANAGEMENT SERVICE
The quality of service has intangible ambiguities different from the tangible objects such as product. However, in association with the characteristics of the service, the service quality does not deviate from the basic direction of modern quality control-the consistency between the quality of service and customer satisfaction. Therefore, the quality of service is generally defined not as a concept of objective quality but that of subjective quality, and can be defined by the meaning of 'perceived service quality' by consumers [5].
This means that the quality of service offered should be consistent with customer's expectation while service quality is defined as a measure of how well the service level provided matches the customer's expectation [6], [7]. Many scholars support the conceptual definition of Parasuraman et al. (1985) which read 'the quality of service is the overall judgment or attitude of an individual in relation to the excellence of a specific service' [8].
It is also shown in Bitner and Hubert's study (1994), which defines service quality as "the overall impression consumers have in relation to the excellence or inferiority of service." Such service quality varies in its diverse theoretical views of the range of services subject to quality assessment [9].
In this study, the quality of management service is a customer-oriented concept that measures customer perception which is defined as the attribute of management service and the satisfaction level of customers who encountered a series of service processes. On the basis of such definition, the study composes the sub-factors of management service quality with environmental quality, process quality, and result quality and analyzes their influence relationship with resident satisfaction.

RESIDENTIAL SATISFACTION
Today, the most noted marketing concept in various fields is customer satisfaction. It is believed that customers who are satisfied with organizations' product and service will bring more profits to the companies. As customer satisfaction became the slogan of companies in the 1980s, companies were absorbed into finding ways to satisfy customers as well as offering services above customers' expectation. Because most managers assume that customer satisfaction and purchasing behavior have much correlation, they believe that the higher customer satisfaction not only can make the higher the consumer's purchase proportion and recommendation rate for the brand or company but also lead to the intention of paying more for products [10].
The concept of customer satisfaction is a key element of marketing concept, and many studies have been conducted to present remarkable research results, but there are some differences depending on the approach and perspective of scholars. Oliver (1981) also described customer satisfaction as the comprehensive psychological state created by customer's mismatched expectation combined with the emotion that consumer had by consumer's earlier experience of purchase [11]. Engel et al., (1982) identified the customer satisfaction as an evaluation [12] of whether the selected product or service matched the beliefs held in advance by customers, and Anderson and Weitz (1992) defined it as the process of matching or discrepancy between expectation and perceived product performance [13].
Ha, Kyu Soo and Jin, Seon Jin (2010) insisted that residential satisfaction refers to the degree of tenant's subjective satisfaction with the house in which they live. They said that the degree of residents' satisfaction was of course related to expectation for a residence of a resident's house, desire, passion, and evaluation for it [14], [15].
On the other hand, at least two requirements must be met to increase customer satisfaction. First, it starts with providing quality products and services that can meet customer expectations from the beginning. It is necessary to supply products faster and provide better services at a lower price even though they are of good quality. Second, effectively and thoroughly dealing with customer complaints is required. In the end, customer satisfaction management is a management method that continuously meets these above two requirements and secures a competitive advantage that cannot be imitated by other companies.

RECOMMENDED INTENTION
Recommendation, when viewed from the perspective of consumer response, is closely related to the behavior after purchase as well as to the customer's information acquisition and his or her purchase. Because word of mouth can affect the purchase and use experience by delivering customer satisfaction or dissatisfaction to others after purchase, the message from customers has a considerable influence [16].
The intention of recommendation has been studied as a 'verbal phenomenon,' and unlike the entire evaluation of experience called 'satisfaction,' word of mouth is defined as communicative behavioral process of informally exchanging positive or negative information between consumers through direct and indirect experiences of individuals [17]. Ryu, K. et. al. (2012) defined the recommendation intention as the process of informally recommending positive information about personal direct experience or indirect experience to others. They also stated that it is a personal evaluation and deliverance to others of the positive things they felt after consumers consumed [18].
The reasons that positive word-of-mouth is important among the customer's reactions are followings: First, positive word-of-mouth is related to one-on-one exchanges and has a great effect compared to other exchanges.
Secondly, because word of mouth is not created by companies but it has a source or consumers, it is understood as a more reliable source of information. Lastly, a behavior of complaining is done only to sellers, and relevant word-of-mouth has a characteristic of spreading rapidly to many people around them. Therefore, the main determinants of word-of-mouth behavior are satisfaction and dissatisfaction felt by customers [19], [20].

RESEARCH OBJECT AND RESEARCH MODEL
In order to carry out this study, a survey was conducted on residents of high-rise residential complex located in a metropolitan area in China. The questionnaire of survey consists of three parts: management service quality, residential satisfaction, and the intention of recommendation. The questionnaire questions about variables except demographic characteristics were composed of Likert 5-point interval scale. In this study, a research model was set up as shown in Figure 2 to examine the impacts of management service quality as an independent variable on satisfaction and behavioral intention based on literature research and precedents [21].

RESEARCH HYPOTHESIS
This study sets up the following hypotheses based on a precedent that the management service quality of high-rise apartments has an effect on residents' satisfaction and intention of recommendation.
Hypothesis 1: The quality of management service will have a positive effect on the satisfaction of residents.
1-1 Environmental quality will have a positive effect on residents' satisfaction.
1-2 Process quality will have a positive effect on residents' satisfaction.

1-3 Result quality will have a positive effect on residents' satisfaction.
Hypothesis 2: Satisfaction on the part of residents living in high-rise apartment will have a positive effect on the intention of recommendation.

DATA COLLECTION, MEASUREMENT AND ANALYTICAL METHOD
The survey for the empirical analysis of this study was conducted for about three months from December 2019 to February 2020 for those who have lived in high-rise apartments in China. 265 copies of questionnaire were collected through the online questionnaire method, and 240 copies were finally used for analysis, excluding 25 copies that were insincere.
The measurement of variables was made by a five-point scale on environmental quality (6 items), process quality (6 items), result quality (5 items), resident satisfaction (7 items), and recommendation intention (4 items) based on the existing precedent studies related to the management service quality of high-rise apartments. And SPSS 25.0 was used for statistical process for the analysis on data surveyed. Frequency analysis was conducted to identify the general characteristics of the subjects, and reliability analysis and factor analysis were conducted to verify the reliability and validity of the measurement tools used in the empirical study. Multiple regression analysis was also utilized to examine the research hypotheses.

STATUS OF DATA
When result characteristics are viewed after analyzing the general status of the data, 48.3% of the male (116 persons) and 51.7% (124 persons) of the female were shown in the data. The age of '40s' was the most with 59.6% (143 people), 'Shandung/Shanxi province' with 48.8% (117 persons), '4-year college graduation' with 30.4% (73 persons), and 'office worker/public servant' with 28.8% (69 persons). Besides, residents of '1 year to less than 3 years' were the most with 30.4% (73 persons) and the average monthly household income with 'less than 2 million CNY' was shown the most with 71.3% (171 persons).

RELIABILITY AND VALIDITY
This study used Cronbach's α coefficient showing the internal consistency of the data in order to analyze the reliability of the measurement tool. In addition, factor analysis was conducted to verify the validity of the measurement items. The factor analysis was performed by using the Varimax-rotation method by the principal component analysis, and only the factors with the eigen value of 1.0 or more were analyzed. As shown in Table  4, Cronbach' α value is shown to be more than 0.9 for each factor, so it is analyzed to be reliable. In addition, the factor analysis results showed that five factors were derived, and the total variance of the whole factor was 83.704%.

CORRELATION ANALYSIS
As shown in Table 5, the results of correlation analysis of this study showed that most of the items were significant, and suitability of the data is secured as the correlation coefficient. In this study, regression analysis is made to identify the relationship between management service quality, satisfaction and recommendation intention of high-rise residential complex apartments in China. The results are as follows. First, the verification result of Hypothesis 1 that the quality of management of high-rise apartments will have a positive (+) effect on the satisfaction of residents is as shown in Table 6. As a result of multiple regression analysis, the explanatory power (R²) of the regression formula is .555, and the result of variance analysis for statistical significance verification of the regression coefficient shows that the significance probability value is .0000, which is meaningful with the value of the significance level .01. The result of multiple regression analysis shows that environmental quality, process quality and result quality under the management service quality of high-rise apartments have a statistically significant positive effect on residents' satisfaction, so all hypotheses 1-1, 1-2, and 1-3 are adopted.

RESULT OF VERIFICATION ON HYPOTHESIS 2:
The result of verifying Hypothesis 2 that the residents' satisfaction in the research model will have a positive (+) effect on the recommendation intention are as follows in Table 7.
As a result of analysis, the explanatory power (R²) of the regression formula was .472, and the analysis of variance shows that the significance probability value is .0000, which is relevant at the significance level .01. As a result of simple regression analysis, the residential satisfaction with high-rise apartments had a statistically significant positive effect on the intention of recommendation, and the hypothesis 2 is supported.

CONCLUSION
This study is to empirically examine how the quality of management service -environmental quality, process quality and result quality -perceived by the residents of high-rise residential complex of China affects the satisfaction of the residents and how the satisfaction of the residents affects the recommendation intention. The results and implications are as follows.
As a result of the empirical analysis, environmental quality, process quality and result quality as sub-factors of management service quality of high-rise apartments in China have a significant effect on the satisfaction of occupancy. Furthermore, it is thought that the occupancy satisfaction has a significant effect on the recommendation intention. Also, it is shown that the process quality (standardization coefficient β=.363, t=5.362), result quality (β=.306, t=5.610), and environmental quality (β=.200, t=3.319) among the sub-service quality factors had a great influence in their order.
Such results of analysis are similar to those in the existing research on service quality, and it is the result showing that the process of offering service has a great impact on residential satisfaction. Therefore, in order to improve the satisfaction of the residents of high-rise apartments and to derive positive attitudes and follow-up behaviors, it can be said that it is important to give priority to paying attention to residents' requirements and taking a quick and friendly treatment of them rather than focusing on making efforts to improve the physical environment quality and its resulting increase of quality.
However, this study has limitations of its scope and samples because it confined its survey into limited period and some specific areas in China. Therefore, it seems to be necessary to expand the scope of the survey in order to overcome these limitations and to continue to study the various conditions of the residence, such as the development of measurement items proactively reflecting the characteristics of the residence in high-rise apartments.
