This paper reports novel empirical results of a choice experiment that elicited the economic values that residents in the Seoul metropolitan area place on the amenity services realized from the landscape views and accessibilities to urban green spaces (i.e., mountains, rivers and urban parks). The 1,000 respondents in the sample were divided into two residential of housing types (apartments vs. houses) and occupancy types (owners vs. tenants). Residents living in apartments are willing to pay an average of 28% (5.0 million KRW per year) above the current housing prices per household for a mountain view, compared to an apartment view from their living room. Their willingness to pay values are about 22% (4.0 million KRW per year) and 10% (1.8 million KRW per year) respectively for a river view and a urban park view. Economic benefits of having access (i.e., a 10 minutes working distance) to mountains, rivers and urban parks are estimated to be an average of 16% (2.9 million KRW per year), 20% (3.6 million KRW per year) and 18% (3.2 million KRW per year), respectively, above the current housing prices per household. On the other hand, access benefits for those residing in houses are 18% (4.7 million KRW per year), 16% (4.1 million KRW per year) and 22% (5.6 million KRW per year) per household, respectively. They are also willing to pay an average of 35% (8.9 million KRW per year) above the current housing prices for keeping or having a garden or vegetation bed. Furthermore, a strong "greenspace premium" is centered around the three Gangnam districts for house-dwellers, whereas it is areas of "new real estate boom" for apartment dwellers.

농촌 지역의 인구 감소 및 그에 따른 지자체의 위기의식이 심화됨에 따라 국내에서도 지역마다 각종 인구 늘리기 시책을 실행하고, 중앙에서 도시민 농촌유치 프로그램 지원 시범사업을 기획하는 등 지역 발전의 기본 요건이 되는 인구 감소의 해결을 위한 노력이 가시화되고 있다. 이에 따라 본 연구는 일본의 정주촉진 정책 사례에 대한 고찰을 통해 국내 정책에의 시사점을 도출하고자 한다. 시마네현은 일본 혼슈의 동해 연안에 위치하고 있으며, $6707.26km^2$의 면적에 약 74만 2천 명의 인구(2005)가 살고 있는 지역이다. 시마네현의 총 토지면적 중 약 80%가 산림면적이며, 경지면적은 41,000ha로 약 6%를 차지하고 있다. 이 중 논이 80%를 차지하여 논농사 중심의 농업이 이루어지고 있으며, 풍요로운 수산자원을 보유하고 있어 어업활동도 활발하다. 이러한 시마네현에서는 UI턴의 촉진을 위해 '산업체험사업'을 1996년부터 시행하고 있는데, 농림어업에 관한 산업체험을 실시하고, 체험 후의 거주지로 빈집을 활용하는 사업이다. 현 외 거주자가 시마네현 내에서 일정시기 산업체험을 하고자 할 경우, 월 50,000엔이 지급되며, 거주지 확보가 어려울 경우 트레일러하우스나 빈집활용주택, 공영주택 등을 임대해주고 있다. 또 시마네 현 내에서 30세 미만의 청년 미취업자가 일정기간 산업체험을 실시할 경우, 체험에 필요한 경비의 일부를 제공해주고 있다. 그간의 실적을 보면 연간 평균 105명이 체험에 참가하고 있으며, 2000년 이후 정착률은 50%를 넘고 있다. 총 259개의 체험 장소에서 월 평균 4명이 참가하고 있으며, 업종별 참가자수는 농업 및 기타(관광, 전통공예), 어업, 임업, 축산업의 순서로 많은 것으로 나타나고 있다. 또한 시마네현의 고츠시에서는 '도시와의 공생 교류' 실현을 위한 9가지 중점시책을 설정하고 그에 따른 사업을 실행하고 있다. 농산어촌의 취락을 유지하는 것이 첫 번째 중점시책으로서 이를 위해 빈집을 활용한 정주와 교류가 활발히 이루어질 수 있도록 주거 정보를 수집, 관리, 웹을 통해 제공하고 있으며, 농지 유동화 및 농림수산물의 직거래 시스템 확립에 주력하고 있다. 이 밖에도 UI턴자 확보를 위해 지역에서 살고, 일하고, 즐기는데 대한 일체적인 정보 제공 시스템을 마련하고 있으며, '고향교육'을 통해 지역에 대한 애착심을 기르는 동시에 지역에서의 취업 지향을 높이는데 힘쓰고 있다. 농촌 정주촉진을 위한 사업 내용면에서는 일본과 우리나라 간 큰 차이가 없다. 그러나 사업에의 의지와 방향 설정, 사업 추진체계 및 운영방식 등에서 발견되는 차이를 주시함으로써 농촌 지역 인구 증가에 보다 실질적으로 기여할 수 있는 정책으로 만들어가야 할 것이다.

The purpose of this study was to estimate the pricing factors of residential lands in new cities by estimating the pricing model of residential lands. For this purpose, hedonic equations for each quantile of the conditional distribution of land prices were estimated using quantile regression methods and the sale price date of Jangyu New Town in Gimhae. In this study, a quantile regression method that models the relation between a set of explanatory variables and each quantile of land price was adopted. As a result, the differences in the effects of the characteristics by price quantile were confirmed. The number of years that elapsed after the completion of land construction is the quadratic effect in the model because its impact may give rise to a non-linear price pattern. Age appears to decrease the price until certain years after the construction, and increases the price afterward. In the estimation of the quantile regression, land age appears to have a statistically significant impact on land price at the traditional level, and the turning point appears to be shorter for the low quantiles than for the higher quantiles. The positive effects of the use of land for commercial and residential purposes were found to be the biggest. Land demand is preferred if there are more than two roads on the ground. In this case, the amount of sunshine will improve. It appears that the shape of a square wave is preferred to a free-looking land. This is because the square land is favorable for development. The variables of the land used for commercial and residential purposes have a greater impact on low-priced residential lands. This is because such lands tend to be mostly used for rental housing and have different characteristics from residential houses. Residential land prices have different characteristics depending on the price level, and it is necessary to consider this in the evaluation of the collateral value and the drafting of real estate policy.

This study investigated and analyzed the rise and fall trend of enrolled students during the recent 30 years with the subject of 607 elementary schools in 11 Education Support Centers (25 Gu-districts) in Seoul to provide the basic data related to establishing the school accommodation plan of the Seoul Education Office. In particular, the study focuses on the 53 small schools in Seoul and examines whether a correlation exists between the 8 factors of the school accommodation plan and the increasing and decreasing of enrolled student numbers. First, 'school establishment policy' should not be a short-term therapy but a long-term and predictable sustainable policy. Second, among the eight factors, there seems to be a very high correlation between the 'aged low-rise house districts' and 'spatially isolated areas'. Third, 'close-packed apartment complexes' and 'rental apartment complexes' are also highly correlated. Fourth, the planning factors such as 'joint school districts, the reconstruction of apartment complexes and the connection to commercial districts' seem to be correlated to some degree. Therefore, further studies are needed to overcome these problems.

Construction business, which is complex and long-term business, requires accurate estimation and verification in construction costs and payment procedure from project planning to the completion of construction phase. And more importantly, it is necessary to investigate and determine the risk factors related to construction costs during the entire process including design planning, construction drawings, and quantity calculating. But, currently, it is not seem to be adequate to cope with the risk and increased construction costs against the operational budget in terms of actual costs when screening and estimating the bidding cost of public apartment. Therefore, this study selected and analyzed 40 sites' report of construction completion account from 2004 to 2010 focused on the adequacy on the modification of contract and design planning and on the complication of the budget in the beginning of the project. This study deducted various risk causes and results by analyzing actual costs according to year, architectural area, region, construction cost and sale/lease classification. We could find out construction risk according to annual variation of government policy and economy, and also deducted risk items by construction characteristic according to region and architectural area. Study result, we first found out the problems of lowest price award system according to the construction costs. The weight of the cost increase risk was analyzed that subcontract and material costs are very high. Roof and tile work were analyzed highly in subcontract cost risk and reinforcing bar and cement were analyzed highly in material cost risk, among direct construction cost. Finally, this study results could be used in comparing the categories of the construction costs made by specific construction process, belonging to the construction costs, with the operational budget made in the beginning of the project that can enable to grasp unpredictable risks over the construction costs and making quantitative analysis for it through analyzing the range of fluctuation and variations led by the fluctuations in the actual construction costs.

With the increasing demand for office space, there have been questions on how office rent distribution produces a change in the urban spatial structure in Seoul. The purpose of this paper is to investigate a relative price gradient and to present a time-series model that can quantitatively explain the dynamic changes in the urban spatial structure. The analysis was dealt with office rent above 3,306 m² for the past 10 years from 1Q 2010 to 4Q 2019 within Seoul. A modified repeat sales model was employed. The main findings are briefly summarized as follows. First, according to the estimates of the office price gradient in the three major urban centers of Seoul, the CBD remained at a certain level with little change, while those in the GBD and the YBD continued to increase. This result reveals that the urban form of Seoul has shifted from monocentric to polycentric. This shows that the spatial distribution of companies has gradually accelerated decentralized concentration implying that the business networks have become significant. Second, contrary to small and medium-sized office buildings that have undertaken no change in the gradient, large office buildings have seen an increase in the gradient. The relative price gradients in small and medium-sized buildings were inversely proportional among the CBD, the GBD, and the YBD, implying their heterogeneous submarkets by office rent movements. Presumably, those differences in the submarkets were attributed to investment attraction, industrial competition, and the credit and preference of tenants. The findings are consistent with the hierarchical system identified in the Seoul 2030 Plan as well as the literature about Seoul's urban form. This research claims that the proposed method, based on the modified repeat sales model, is useful in understanding temporal dynamic changes. Moreover, the findings can provide implications for urban growth strategies under rapidly changing market conditions.

This study aims to investigate the environmental equity of the accessibility to urban neighborhood parks in the city of Daegu. The spatial distribution of urban neighborhood parks was explored by spatial statistics and the spatial accessibility to them was then evaluated by both minimum distance and coverage approaches. Descriptive and inferential statistics such as proximity ratio, Mann Whitney U test, and logistic regression were used for comparing the socioeconomic characteristics over different accessibilities to the neighborhood parks and then testing the distributional inequity hypothesis. The results from the minimum distance method indicated that Dalseo-gu had the best accessibility to the neighborhood parks while Dong-gu had the worst accessibility. It was apparent with the coverage method that Dalseo-gu had the best accessibility whereas Dong-gu and Nam-gu had the worst accessibility to the neighborhood parks at 500m and 1,000m buffer distances. There existed the spatial pattern of environmental inequity in old towns with respect to population density and the percentage of people under the age of 18. The spatial pattern of environmental inequity in new towns was explored on the basis of the percentage of people over the age of 65, the percentage of people below the poverty level, and the percentage of free of charge rental housing. These results were closely related to the development process of urban parks in Daegu stimulated by the quantitative urban park policy, urban development process, and residential location pattern such as permanent rental housing and free of charge rental housing. This study further extends the existing research topics of environmental justice related to the distributional inequity of environmental disamenities and hazards by focusing on environmental amenities such as urban neighborhood parks. The results from this study can be used in making the decisions for urban park management and setting up urban park policy with considering the social geography of Daegu.
