Introduction How is housing appraised? Are the physical character- istics of housing the only indicators of its value? While these have been ongoing questions in housing research, many re- searchers have also discussed housing prices per se or in relation to locational characteristics (Dong et al., 2019; Li et al., 2019; Wittowsky et al., 2020). In reality, housing prices reflect not only the physical characteristics of a house itself but also the various elements of its location and surrounding environment (Adair et al., 2000; Dong et al., 2019; Lan et al., 2018; Li et al., 2019; Zahirovic-Herbert and Gibler, 2020). In particular, the neighbourhood plays an important role (Bramley et al. 2008; Lan et al., 2018; Wittowsky et al., 2020), in that housing prices vary significantly among different sub- markets segmented according to accessibility (Adair et al., 2000; Feng et al., 2020; Ki and Sung, 2020; Sung and Ki, 2021). Previous Seoul-based case studies, which mainly focused on how urban public facilities affect housing prices over a large area, such as a residential district (Jin and Sohn, 2005; Kim, 2012; Kim and Lee 2007; Lee, 2010), have primarily addressed the extent to which access to educational facilities influences housing prices. Further, recent studies on cultural facilities and green spaces have explicitly demonstrated that ===== PAGE 6 (score 14, numeric-paren 3, table-words 3, var-words 5) ===== Effects of Educational and Cultural Facilities on Housing Prices in Seoul from an Accessibility Perspective 534∙Journal of People, Plants, and Environment Vol. 24, No. 5, 2021 where Y denotes the housing price, x is a matrix of observations on the explanatory variables, and ρwy is the spatial lag (or error) variable. ρ assesses the degree of spatial correlation and w is the spatial weights matrix. The value of ρ ranges be- tween -1 and 1, with ρ = 0 signifying no spatial correlation. Under a positive ρ, housing prices are expected to be higher if spatially adjacent housing prices are higher, while ε is a vector of the independent and equivalently distributed error terms (Ward and Gleditsch, 2008). Spatial regression models include SLM and SEM, which use spatial regression dependencies and spatial regression errors, respectively. We determined which model was more suitable by comparing them with the results of the OLS model. The OLS model was tested for suitability under the assumptions of normality, equal variability, and spatial independence of errors (Park and Ham, 2018). Similarly, the spatial depend- encies of dependent variables and regression model error terms were examined using the Lagrange multiplier (LM) lag and error. If the LM lag and error are meaningful at the 5% sig- nificance level, the null hypothesis of the spatial independence of dependent variables and error terms is rejected. If only one of either the LM lag or error is statistically significant, selecting a more adequate model should be considered. If both values are significant, the robust LM lag and robust LM error statistics test functions are used for reselection, as a last resort (Park and Ham 2018). Park and Ham (2018) relied on the log-like- lihood, Akaike information criterion (AIC), and Schwarz criterion (SC) results to determine the suitability of spatial regression models. Compared to the results of the OLS mod- el, the model with a higher log-likelihood and lower AIC and SC was considered appropriate. To determine the effects of educational and cultural factors, we used the number of public libraries and private educational facilities as a proxy for the educational factor (independent variable). Regarding the cultural factor, art museums, museums, historical sites, and urban parks are used as independent variables. Table 3 and Table 4 present detailed statistical information for the independent and dependent variables. Results and Discussion As shown in Fig. 3, we illustrated housing prices and their independent variables using ArcGIS 10.8. On average, the number of private educational facilities was large (31.65) and showed a high standard deviation (17.74) compared to other facilities. Fig. 3 also shows that private educational facilities tend to be clustered in the south-eastern part of Seoul, where housing prices are generally higher regardless of the housing type. However, public libraries had a relatively low standard deviation (1.26), implying that a similar number of public libraries are distributed across districts, as can also be seen in Fig. 3.

Descriptive statistics of independent and dependent variables Variables Definition Dependent variable Price by housing type Multi-unit housing Real estate transaction price Housing types are classified as follows: single-unit housing, multi-unit housing, or apartment. Single- and multi-unit housing tends to be occupied by less affluent families, whereas relatively affluent families reside in apartments (Kang et al., 2019). More than half of the population (50.7%) in Seoul resides in apartments (Kang et al., 2019). Furthermore, Jeon (2015) suggested that most residents in Korea prefer apartments because an apartment complex that has access to educational and cultural facilities is more attractive than single- or multi-unit dwellings when raising children. Single-unit housing Apartment Independent variables Educational factors Public library Number of public libraries in Seoul Public library means a library established and operated by local government for information, reading activities, and cultural activities by the public. The libraries we employed as an independent variable are local public libraries, not university or special libraries, specially built for residents. Private educational facility Number of registered private academies and study centres in Seoul Private educational facilities in this study are categorized into two types: those with curricula that facilitate entrance into prestigious universities and those providing lifelong or vocational education. Cultural factors Art museum Number of art museums in Seoul The reason for distinguishing museums from art museums is that the Museum and Art Gallery Support Act of South Korea (Government of the Republic of Korea, 2018b) considers them to be different. Museum Number of museums in Seoul Historical site Number of historical sites in Seoul In this study, historical sites cover every historical property registered by central and local governments. In South Korea, historical sites can be categorized into three types: nationally assigned cultural properties, city assigned properties, and nationally registered properties. Number of urban parks Number of urban parks in Seoul The park concept we employed in this study includes parks established and managed within the urban residents’ immediate neighbourhood structure; it includes small-sized, children’s, and neighbourhood parks.

The Jarque-Bera test statistic of 1286.0811 (p < .05) signifies an abnormality in the spatial autocorrelation test of error terms. Therefore, this test leads to spatial re- gression models instead of the OLS model. Using the results of the spatial regression model analysis, we selected the more suit- able model between SLM and SEM. The R2 value (0.303476) of the SLM is higher than that of the SEM, and is also more robust. Additionally, the log-likelihood value of the SLM (-9,084.95) is higher and their AIC and SC are lower than those of the SEM. Furthermore, the likelihood ratio test of the SLM generates statistically significant results, indicating it is more suitable than the SEM. For this reason, the SLM was considered the most suitable model based on the analysis results. The SLM results reveal that educational (private educational facilities) and cultural (art museums) factors exert positive influences on single- unit housing prices. However, historical sites adversely affect single-unit housing prices. Table 8 shows the analysis results of the OLS model, SLM, and SEM using apartment price as the dependent variable. The Jarque-Bera test statistic of 1,008.7673 (p < .05) signifies an abnormality in the spatial autocorrelation test of the error term. Moreover, the Breusch-Pagan test statistic (26.1987, p < .05) indicates heteroscedasticity in the error term. Therefore, spatial regression models are preferrable to the OLS model. The spatial regression model analysis allowed the most suitable model between the SLM and SEM to be selected. The R2 value (0.171330) of the SLM was more robust and higher than that of the SEM.

For this reason, the SLM was re- garded to be the most suitable based on the analysis results. The results reveal that the educational factor exerted both positive (private educational facilities) and negative (public libraries) influences on apartment prices. This finding is important, because while public libraries were statistically significant in the spatial regression model, they were insig- nificant in the OLS one. This indicates that spatial re- gression analysis considers spatial effects and must be ap- plied to measure the spillover effects of sites with a specific space.

First, while the SEM is suitable for analysing multi-unit housing prices, the SLM is suitable for single-unit housing and apartment prices. Second, private educational facilities and art museums have positive influences on most housing prices, while historical sites have a negative influence. Finally, public libraries and urban park areas have negative effects on apartment prices. Thus, this study can imply that historical sites, public libraries, and urban park areas can be interpreted as less influential factors in housing prices compared to private educational facilities and art museums. Table 9 presents a comparison of our research results with those of Ki and Sung (2020). Both studies adopted the same independent variables but at different spatial scales: the res- idents’ immediate neighbourhood (dong) and the residential district (gu), respectively. The test of the SLM is more robust in terms of residents’ immediate neighbourhood (dong) analysis, especially between single-unit housing and apartments, sug- gesting that the most proximate public facilities can be con- sidered a relevant factor in explaining residential housing prices, which is also consistent with the results of Wittowsky et al. (2020). Based on this comparison, we suggest the following policy implications. First, private educational facilities positively influence all types of housing at the gu and dong levels, which is a finding consistent with most of the previous studies (Cho et al., 2020; Ha and Lee, 2013; Kim and Kim, 2019). The residents of Seoul closely associate private educational facilities with students’ academic performance and consider them as essential educational facilities (Ha and Lee, 2013). Consequently, parents of students tend to relocate close to private educational facility clusters (Park and Lee, 2011) to allow easy access to education for their children, thereby positively influencing housing prices in Seoul at both the gu and dong levels. Second, art and general museums have positive effects on the prices of all housing types in a residential district (gu). Art museums have a positive effect on single- and multi-unit housing prices in residents’ immediate neighbourhood (dong). In particular, art museums positively affect social and edu- cational environmental satisfaction, and in turn, residential environmental satisfaction (Ki and Sung, 2020). For example, a recent study (Han, 2020) suggested that art museums have Dependent variable (apartment) OLS SLM SEM Rho -0.0169392 Lambda -0.006901 R2 0.171184 0.171330 0.171206 Adj.

Continued ===== PAGE 12 (score 15, numeric-paren 0, table-words 1, var-words 13) ===== Effects of Educational and Cultural Facilities on Housing Prices in Seoul from an Accessibility Perspective 540∙Journal of People, Plants, and Environment Vol. 24, No. 5, 2021 gained in popularity as art education program venues for nearby elementary schools. Therefore, the art museums in Seoul serve not only as exhibition spaces but also as educational facilities. Additionally, another study (Seresinhe et al., 2016) showed that the image of art represented by art museums can affect housing prices. These findings indicate that the accessibility of art and general museums reflects residents’ needs and preferences, and in turn, influences housing prices. Third, public libraries negatively influence apartment prices at both the gu and dong levels. This implies that the percep- tion of public libraries needs to change from ‘book lending library’ to ‘community cultural complex’ (Noh and Kim, 2019). Notably, residents regard public libraries as community spaces for cultural activities (Seoul Metropolitan City, 2019). If public libraries do not meet their expectations, they lose their appeal and fail to motivate residents to work within the community for cultural reinforcement (Adkins and Hussey, 2006), which would have an adverse effect on apartment prices. Although apartment residents accept public libraries as a type of edu- cational facility, they consider them less important than pri- vate educational facilities. Therefore, public libraries are re- quired to serve as both educational and cultural facilities for residents. Enduring efforts and prompt support from both local and central governments are necessary to achieve this con- version for public libraries. Beyond this, policy-makers could adopt measures to transform public libraries from basic fa- cilities to complex systems with various educational and cultural programs (Gu, 2019; Seoul Metropolitan City, 2019). Fourth, historical sites negatively influence the prices of most housing types, at both the gu and dong levels. Historical sites are often perceived as a hindrance to local physical development (Been et al., 2014) because the disadvantages of construction restrictions appear to outweigh their cultural benefits, thus adversely affecting social environment sat- isfaction (Ki and Sung, 2020). In other words, historical sites fail to attract public interest as cultural heritage sites (Hyundai Research Institute, 2018), due to the lack of under- standing of the inherent value and information they provide (Korea Cultural Heritage Administration, 2018). To address this, public efforts must be made to improve the quality of the interpretive content of signs, interpretation of cultural heritage, and relevant cultural programs to help residents appreciate the value of historical sites. Finally, urban park areas negatively affect the prices of all housing types at the gu level, and of apartment prices at the dong level. Although urban parks were initially created to meet residents’ needs (Kim et al., 2006), negative external- ities, such as noise or disturbances from frequently used com- munity sports facilities in the park, can cause inconvenience to residents, adversely affecting cultural environmental sat- isfaction (Ki and Sung, 2020) and in turn, the housing pri- ces in the area (Lin, 2016). For instance, apartment resi- dents often register civil complaints against park users due to noise disturbances (Sung and Ki, 2021). In particular, considering that most apartments in Seoul Metropolitan City have their own green spaces, urban park areas - which negatively affect apartment prices at the dong level - seem unnecessary. Therefore, urban park planners must find al- ternative means to minimize negative externalities, such as employing landscape treatments to screen out disturbances (More et al., 1988). Despite the significance of this study, we acknowledge its limitations.
