정창무(Jung Chang-Mu),이상경(Lee Sang-Kyeong) 대한국토·도시계획학회 2001 國土計劃 Vol.36 No.5

The focus is on explaining urban spatial structure of the City of Daejeon, using satellite image data. This is a particularly interesting time to study urban structure because Greenbelt systems are undergoing qualitative change. A sketch is presented of how urban form of Daejeon has evolved in recent years, followed by some observations on how to measure its characteristics with structural equation models. In the late 1980s, Greenbelt system had a deep impact in Daejeon's spatial structure. Yet, the Greenbelt system has no effect on the compact development of the City of Daejeon because of leap-frog sprawl in 1990s.

본 논문은 자율주행 자동차 상용화와에 따른 전국 상업 공간 구조에 미치는 영향에 대해 연구하고자 한다. 자율주행 자동차의 출현은 도시에 극적인 변화를 가져올 것으로 예상된다. 그러나 최근의 연구는 국토 공간구조의 가능한 변화 추정이 아닌, 주로 차량 기술에 초점을 맞추고 있다. 이러한 배경에서 본 연구는 일련의 시나리오를 개발하고, 자율주행 자동차로 인한 편익 발생 모델을 구축하고, 자율주행 자동차 사용으로 인한 소득 증가로 인해 국토 공간구조의 변화를 분석하는 것을 목표로 한다. 문헌 검토를 기반으로 네 가지 시나리오를 설정하였으며, 시나리오 별 자율주행 자동차의 상용화 정도를 예측하기 위해 주요 요소의 계수를 포함한다. 각 시나리오 별 편익 계산한 것을 바탕으로 상권의 소득 및 직원 증가에 따른 전국 상업 공간 구조의 변화를 제시한다. 본 논문의 시뮬레이션 결과 자율주행 자동차가 초기 단계에서는 특정 지역에만 분포되어 있기 때문에 상업 연면적 증가량의 지역적 격차가 증가하는 것을 보여준다. 하지만 자율주행 자동차 보급률이 증가함에 따라 전국적으로 상권의 매출, 고용자 수 증가로 교외 지역도 발달하여 지역 불균형 개발이 감소한다. 장기적으로 시간이 지남에 따라 지역적 격차가 줄어들고 국토의 균형적 개발이 가능할 것으로 예상된다. This paper aims to investigate the relationship between commercialization of autonomous vehicles and its influence on commercial spatial structures nationwide. The emergence of autonomous vehicles is expected to bring about dramatic changes in our cities. However, recent studies mainly focus on the technology of vehicles, not the estimation of possible changes. For this reason, our study aims to develop a set of scenarios, build forecasting model for benefits of autonomous cars, and analyze the changes in territory due to the increased income from using autonomous vehicles. Four different scenarios have been identified based on literature review, containing different coefficients of the main elements for forecasting future commercialization of autonomous vehicles. From the benefits we concluded in each scenarios, which were calculated through main elements, we propose the change in commercial spatial structures nationwide due to the increased income and employee. Our simulation results show that in the early stage, regional gap increases since autonomous vehicles are only distributed in specific area. However, as autonomous vehicles’ dissemination rate increases, suburban area also develop due to increasement in revenue and number of employee, leading to reducement in territory unbalanced development. Regional gap decreases as time passes and territory balanced development increases in the long run.

도시에서 배출되는 탄소와 온실가스는 기후변화에 큰 영향을 미친다. 기후변화를 방지하기 위해 전 세계적으로 친환경 건축물 보급을 위해 노력하고 있으며 친환경 인증 건축물이 부동산 가격에 미치는 영향에 대한 연구도 진행되었다. 본 연구는 친환경 건축물이 부동산 가격에 미치는 영향을 건축물의 용도에 따라 비교하기 위하여 진행되었다. 이에 따라 본 연구는 서울시 강서구의 주거용 부동산(아파트)과 상업용 부동산(상가 · 사무실)을 대상으로 에너지효율등급을 부여받은 건축물이 매매가격에 미치는 영향의 정도를 비교 분석하였다. 이를 위해 평당 거 래가격을 종속변수로 두어 다중회귀 분석의 형태를 띤 해도닉가격모형 분석을 수행하였다. 실증분석 결과, 매매 가격에 에너지효율등급이 미치는 영향력의 정도는 상업용 부동산(β = 0.045)보다 아파트(β = 0.537)에서 더 높게 나타났다. 본 연구는 친환경 건축물이 단순히 매매가격에 영향을 미치는지에 대해 분석한 선행연구들과는 달리 건물의 용도에 따라 영향정도를 비교한 연구라는 데에 의의가 있다. 향후 연구에서는 데이터센터, 오피스텔, 물류 시설, 공장 등 보다 다양한 형태의 건물이 부동산 시장에 미치는 영향을 연구할 필요가 있다. 또한 지역의 특성이나 계절에 따른 에너지효율등급의 실효성 연구 등 다양한 관점에서 친환경 건축물의 실요성에 대해 분석할 필요가 있다. 본 연구결과를 기반으로 전략적인 친환경 건축물 공급을 유도할 수 있다는 것으로서 그 가치가 있다. Pollutants and carbon emitted from cities have a major impact on global warming and climate change. Considerable efforts are being made to supply eco-friendly buildings to reduce greenhouse gases emitted from buildings worldwide. In addition, numerous studies have shown that eco-friendly building certification affects real estate prices. The purpose of this study is to examine the effects of eco-friendly buildings on real estate prices spanning different types of buildings. This study investigated the relationship between energy-efficiency ratings and real estate prices for residential buildings and commercial property in Gangseo-gu, Seoul, Korea using the Hedonic price model analysis. The influence of energy-efficiency rating on real estate prices was found to be greater on residential buildings (β=0.537) than that on commercial properties (β=0.045). This study expands from the previous studies that simply analyzed whether eco-friendly buildings had an effect on real estate prices by comparing the degree of influence on different building types. Future research needs to study the impact of more diverse types of buildings, such as data centers, officetels, logistics facilities, and factories, etc. on the real estate market beyond residential and commercial buildings. In addition, studies comparing the effect of eco-friendly buildings on prices depending on the characteristics of the region or the effectiveness of season-dependent energy efficiency grades may be conducted. Based on the results of this research, development strategies can be established in the private sector, and the public sector can make policies to induce the private sector to provide more eco-friendly buildings.

The purpose of this study is to find out a basis on enacting development density which is raising conflict between local governments and developers recently. For this study we investigated the relationship between floor area ratio and housing price using ridge regression model, and also relationship between floor area ratio and business profitability using feasibility study. As a result, it seems that the floor area ratio was about 230% when the apartment price is at the maximum. The floor area ratio when business profitability is at the most is differs in 300∼380% by the development methods. Therefore, 230% floor area ratio is proper for the long-term residential amenity than short-term profitability. Addition to that, further research is required for the profit of the developers.

주택가격이 출생률에 미치는 영향

In Korea, it is not a surprising fact that the cost of marriage more than doubled in 2007 compared to 2001. There are so many people who can't get married due to financial reasons because they can not afford to buy their own homes when they get married. President Lee Myung-bak pledged a fundamental change to welfare policies during the election campaign. The government has proposed providing newly wed couples with 50,000 new, affordable homes every year to tackle the nation`s low fertility rate and low marriage rate. This paper assesses the determinants of low marriage and birth rate using panel data of the National Statistical Office. The two stage least squares dummy variable structural regression is applied to test independent variables to affect low marriage and birth rate in Korea. We found that soaring housing costs encourage the marriages of the Korean young and do not have any effects on birth rates. It means that soaring housing costs will increase marriage bonuses rather than reducing marriage penalties by sharing living expenses such as housing with his or her spouse. The government housing policies for increasing birth rates are not likely to be successful.

The paper aims to identify factors for short-term supply and demand of hotel rooms. In order to explain the effects among variables, simultaneous model is used as a econometrical model. Twenty nine years of time series data about five-star .hotels in Seoul were used as endogeneous variables and socio-economic data of South Korea, America, Japan as exgeneous variables. As a result of this study, hotel room supply at certain point of time seems to be influenced by the vacancy of hotel rooms, room rate, exchange rate, GDP of Korea and USA. And hotel demand is influenced by the number of residents in hotel, their expenditure on hotel rooms and room rate.

The study of household formation is important for the real estate industry, because such demographic changes and patterns determine the level of demand for residential real estate. This paper investigates the effect of household formation on jeonsei price and housing rent. Most of empirical research on housing market in Korea have not been tested before in models and hence this study enriches the knowledge on the relationship of housing market and household formation and its consequent potential demand for rental and ownership housing units in terms of housing rent and jeonsei price. Parameter estimates reveal a considerable response of jeonsei price and monthly rent not only to general marriage rate but also other socio-economic variables. As a general marriage rate goes up, jeonsei and monthly rent increase. Analysis of housing market ignoring the endogeneity of household formation is thus potentially biased.

호텔객실판매율과 평균객실요금 간의 관계 분석

Hotel's guestroom revenue is most closely tied to hotel's average daily room rate (ADR) and occupancy rate. The study explores relationship between the average daily room rate and the occupancy rate with the data of 37 five star class hotels in Seoul. A simultaneous-equation model is used to explore the relationship. The results suggest the connection between occupancy and rate involves a lot of give and take indicating the upsides in occupancy rates have negative impacts on hotel's average daily room rates and the reductions in hotel's average daily room rates have positive impacts on occupancy rates.

The purpose of this paper is to investigate the influence of housing unit plan and condominium site configuration on the housing price in Paju. For the analysis, this study utilized regression modelling techniques with the data from 318 condominium buildings of 25 sites in the Paju city using Space Syntax methodology to measure the relative connectivity and space integration. The results shows that space configuration exerts significant influence on housing prices. A real relative asymmetry(RRA) of spatial layouts of kitchen and a mean depth(MD) of bathroom at unit floor plan are deeply related to the housing prices.
