본 연구의 목적은 창업기업의 생성과 소멸이라는 생애주기 변화와 관련하여 나타나는 공간분포 패턴의 차이를 확인하는 것이다. 이를 위하여, 본 연구에서는 전국기업체총람과 폐업기업정보를 활용하여, 2007년부터 2009년까지 수도권에서 창업한 기업의 위치정보와 생성시점, 그리고 소멸시점을 파악하였다. 창업기업의 생멸분포 패턴에 대한 분석은 공간상의 분석단위에 대한 분포패턴을 정량적으로 분석하는 방법론인 평균점, 표준거리, 타원형 표준편차, 그리고 공간자기상관도 분석기법이 적용되었다. 분석 대상 창업기업 5,810개 중, 1,322개 기업이 5년 내에 소멸함으로써 77.25%의 5년 생존율이 산정되었다. 지역별 생멸분포 패턴의 분석 결과, 수도권 전체, 서울, 그리고 인천 경기 모두에서 기업의 생성분포에 비해 소멸분포가 분산의 정도가 큰 것으로 나타났다. 또한, 기업속성별 생멸분포 패턴 분석결과, 기업의 규모와 업종에 따라 창업기업의 생성과 소멸분포에 차이가 있는 것으로 확인되었다. The purpose of this paper is to verify the spatial distribution difference between formation and dissolution of start-up firms related to life-cycle. For this purpose, a Korean business directories and information on business closures were used, and location information, starting time, and closure time of start-up firms in the Seoul metropolitan region from 2007 to 2009 were generated in this study. It applied The spatial distribution analysis methods on the formation and dissolution of the start-up firms included Barcki measurements and global spatial autocorrelation. The total number of start-up firms was 5,810, and their five-year survival rate was 77.25%. The dissolution pattern of the start-up firms was dispersed more than their formation pattern in each of the Seoul metropolitan regions, the city of Seoul, and the city of Incheon-Gyeonggi province. In addition, differences between the formation and dissolution patterns according to size and industry category of the firms were confirmed.

The aim of this study is to explore the determinants of the residential duration at a current residence after a household member’s change according to the life-cycle variation. This study carried out via an empirical analysis using the Cox Proportional Hazard Model with Korean Labor and Income Panel Study data from 2000 to 2008 for the Seoul Metropolitan Area. Regarding the results of the empirical analysis in the case of increased households, older householders, households with school-aged students and younger children, those with more family members, and house owner-occupier households staid longer at the same place. On the other hand, in the case of reduced households, older householders, households without school-aged students and younger children, owner-occupiers, and occupants living in a single detached house have been living longer at the same place. These results show that the factors affecting the duration of residence at a place differed by the pattern of the household member’s change.

The purpose of this paper is to empirically identify the difference in residential satisfaction and its affecting factors by household rental type in the Seoul Metropolitan Region. For this, rental housing types were defined as long-term public rental housing, short-term public rental housing, and private rental housing. The analysing data was constructed using the 2011 Korea Housing Survey, and the methodologies used were Kruskal-Wallis test and ordinal logistic regression. The main results of this study are as follows. First, the levels of residential satisfaction differed statistically among the rental housing types. Those in public rental households had higher satisfaction values than those in private rental housing dwellers. The reason for this is that residential satisfaction is a subjective response of residents. Second, in almost every domain—household attributes, housing properties, and economic conditions—the significance and influence of explanatory variables on housing and residential environment satisfaction varied according to the rental housing type. These results imply that public rental housing policy needs to concentrate on the supply of affordable housing and improvement of housing performance and residential quality in Korea. This paper is significant for constructing national rental housing policies considering the residential satisfaction characteristics of rental housing types.

The purpose of this research is to develop the model of defining the spatial range of a subway catchment area in consideration of moving distance from the platform to the station entrances. The model, which has some assumptions, was implemented by using spatial analysis technique of geographical information system. The model was applied to the stations of the Seoul Metropolitan Subway in 2010. When comparing the catchment areas derived from the model and the ranges of subway catchment areas in the previous studies, there were wide differences from 0.2% to 58.55% by stations. To review an adequacy of the model, an empirical analysis on the relationship between the subway users and the physical conditions density, diversity, and design (ratio of the 4-way intersection), which are 3-Ds of TOO, in the catchment areas was carried out. The model proposed in this study has better explanatory power than the methodology for defining the spatial range of the catchment areas in the previous studies based on the radius of 500m.

The purpose of this study is to comprehend the factors on transportation energy consumption of each municipality type by variation patterns of population and workers. The municipality types were classified by population change rate and workers change rate: the neighboring region of metropolitan cities and the concentrated growth area in metropolitan cities (Group A), the partial inner region in metropolitan cities, the provincial small and medium-sized cities, and their surrounding areas (Group B), and the old downtown areas in metropolitan cities and the region based on primary industry (Group C). The differences of the kinds and influence of factors affecting transportation energy consumption by the region types were confirmed. The Group A was needed of the surrounding area-dependent reduction policy through the supply of services based on the demand. And the municipalities included in the Group B was required to control the vehicle use. The effective policies to reduce transportation energy consumption in the Group C were confirmed as follows: the reduction of travel distance, the supply of transportation facilities in order to promote the use of public transport in the long-distance travel, and the mixed development through the housing supply in the commercial and business district.

The purpose of this study is to explore empirically the relation between the components of agglomeration economies and the survival of small start-up firms in the Seoul metropolitan area (SMA). In this study, Cox-proportional hazard analyses were applied using data obtained from Korean Business Directories from 2007 to 2014 and the information on Korean business closures. The results showed that the components of agglomeration economies, as well as firm attributes, characteristics of industrial activity and macroeconomic factors, were significant determinants of the survival duration of small-sized start-up firms. The detailed results of the empirical analyses are as follows: The diversity index, which is a representative variable of Jacobs externality, had a negative effect on the firm’s survival in the SMA. The specialization index, which is a proxy variable of Marshall-Arrow-Romer externality, was a positive determinant in Seoul. Further, the effects of local competition factors, which are related to Porter externality, were negative in Incheon and Gyeonggi province. These results will be significant for not only consulting on the establishment of new firms in the private sector, but also the construction of industrial policies by national and local governments.

This article aims to evaluate residential environment based on safety, healthy, convenience, amenity and sustainability, and to ascertain the conformability between residential environment and housing price in Seoul. The spatial analyses are employed in the calculation of residential environment indices. For the spatial analysis, Seoul is partitioned off into 3,778 grids(400m×400m). The results show that public land development districts or redevelopment project districts are better than pre-existing residential area in quality, although the former is more dense than the latter. On the other hand, CBD, southeast-district and Han-river frontages are relatively higher than the out of downtown Seoul in the housing price against the residential environment. This means that not only residential environmental but also socioeconomic factors(development expectation, educational conditions, commuting distance, and so on) work together as a housing price.
