The purpose of this study is to analyze the spatial characteristics of inter-firm linkages and innovation networks of firms which are located in Gyeonggi border regions. Through this analysis, this study aims at understanding the spatial characteristics of economic activities of firms in Gyeonggi border regions. More importantly, this study focuses on revealing how the spatial characteristics of economic activities of firms affect future growth potentials of firms and regional economic growth. The main findings of this study are as follows. According to the analysis of spatial material linkages, the firms in both footloose location and industrial complex are all proven to be strongly dependent on the Capital Region. Owing to the weak level of the local material linkages, the effects on regional economic growth are limited. But firms in industrial complex contribute more to regional economic growth. The analysis of spatial employment linkages shows that the local linkages are comparatively strong. But the differentiation of residences weaken the positive effects on regional economy. As a concluding remark, the harmony with local linkages and non-local linkages is required to promote future growth potentials of firms and regional economic growth.

Hub network design for freight transportation is a decision process that determines hub locations together with freight transportation routes among shippers so as to ultimately minimize total logistics cost. This study presents the optimal location of hubs by strict hub network design policy with single allocation, which overcomes the limitation of Kim et al. (2008) that does not allow direct transportation among shippers. The greedy-interchange algorithm is employed for hub location decision process, and EMME/2 is adopted for the route searching process. Application of the processes to the nationwide highway network shows that the best hub locations in order are Seoul metropolitan, GyeongNam, Chung-nam, Jeon-Nam, Gyeong-Buk, Chung-Buk, and the locations are concentrated on the Seoul-Busan corridor. The strict hubnetwork design policy with single allocation increases the transportation distance but decreases the transportation cost by passing through the hubs instead of direct transportation. The reduction in total transportation cost can be achieved as the number of hubs increases, but the amount of the reduction gradually decreases because the cost reduction from the decrease in detour transportation distance between non-hubs and hubs becomes less than the discount reduction from dispersion of inter-hubs transportation volumes.

The purpose of this paper is to analyze the effects of location factors on sales by restaurant type in the six districts of Seoul (Jongno-gu, Jung-gu, Yeongdeungpo-gu, Gangnam-gu, Seocho-gu, and Songpa-gu). Ordinary least squares (OLS) regression model is selected for four restaurant types whose spatial autocorrelation is not identified, spatial lag model (SLM) is only selected for seafood restaurant, and spatial error model (SEM) is selected for nine other restaurant types. The floating population and the workers of surrounding businesses have generally positive effects on the sales of restaurants. The floating population elasticity of the sales of restaurants are found to be in the descending order of Oriental food, pub, Western food, and traditional food restaurant, and the elasticity of the workers of surrounding businesses are in the descending order of bakery, Oriental food, and Western food restaurant. The spatial multiplier effects are in the descending order of Oriental food, pub, and Western food restaurant. There is a statistically significant sales gap between roast meat, pub, and bakery in Gangnam-gu and those in five other districts. The results of this research can help in starting a restaurant in that they can provide information on the suitability of location by restaurant type.

본고(本稿)에서는 1970년 이후 한국(韓國)의 사회간접자본투자정책(社會間接資本投資政策)이 지역간 균형발전(均衡發展)에서 담당한 역할과 그 투자현황(投資現況)을 분석하였다. 이론적 분석에 의하면 사회간접자본투자(社會間接資本投資)는 지역발전의 주요정책수단이 되고 있다. 그러나 1970~85년의 기간에 도로(道路), 통신(通信) 등 주요 사회간접자본(社會間接資本)의 지역간 격차는 현저히 감소되었음에도 불구하고 성장(成長)의 지역간(地域間) 불균형(不均衡)은 크게 개선되지 못하였다. 이는 사회간접자본(社會間接資本)의 지역격차 완화로 수도권(首都圈)을 중심으로 하는 성장지역(成長地域)의 입지여건(立地與件)의 비교우위성이 약화되었으나, 수도권지역(首都圈地域)의 입지적(立地的) 이점(利點)을 상쇄할 만한 투자환경(投資環境)이 지방에 조성되지 못하였기 때문이다. 따라서 실질적인 지역발전을 도모하기 위하여는 입지여건(立地與件)이 상대적으로 불리한 지방에 기업투자(企業投資)를 유인(誘引)할 수 있는 세제(稅制), 금융(金融) 및 행정절차상(行政節次上)의 지원책(支援策) 등을 강화하여 해당지역의 산업활동(産業活動)을 촉진할 수 있는 정책이 함께 추진되어야 한다. 또한 지역의 필요성에 부응하는 사회간접자본투자(社會間接資本投資)를 도모하기 위해서는 지역의 특수성과 주민의 여론을 반영하여 지방정부(地方政府)가 투자결정을 주도할 수 있도록 지방정부의 재정지출 재량권이 제고되어야 한다.

The purpose of this study is establishing how to build the area of local agents and regional offices in the oil company using GIS technique by reviewing on the spatial distribution pattern and characteristics of the sales area of oil products. Location-allocation and spatial interaction model are cooperated in order to establish sales area of petroleum products distribution system. Location-allocation model is used in the capital region where local agents are concentrated on like Kyoung-gi local agent. Spatial interaction model is used in the rest of the area in Korea to analyze the sales range of the regional offices in oil company. Each office made a big difference in registered cars and population because of the level of petroleum consumption in each sales area.

The purpose of this study is to analyze the impact of the Kwang-yang Iron and Steel Co.(KSCO) on the industrialization of the economic structure in Kwang-yang area. The research used the shift-share analysis and regional growth rate differential analysis. KSCO has influenced this area by changing the economic structure from traditional agriculture and fisheries to the manufacturing industry. KSCO also has influenced the population of Kwang-yang area. The number of employees grew from 594 in 1981 to 29,865 in 1992. However, after 1992, employee numbers decreased to 23,399 in 1998. KSCO was constructed in the region of traditional agriculture and fisheries in 1981. The social and economic status of the Kwang-yang area has changed greatly due to the growth of KSCO and the corresponding influx in population. KSCO has developed the related industry and changed this area into a booming industrial city. The number of employee has rapidly increased. At the end of the year 2000, 17,240 people work for KSCO and 39,593(28.7%) of the total population of Kwang-yang are related to KSCO.

Purpose: This study analyzes accessibility of 10 hydrogen charging stations in Seoul and identifies areas that were difficult to access. The purpose is to re-analyze accessibility by adding a new location in terms of equity and safety of location placement, and then draw implications by comparing the improvement effects. Method: By applying the location-allocation model and the service area model based on network analysis of the ArcGIS program, areas with weak access were identified. The location selection method applied the 'Minimize Facilities' method in consideration of the need for rapid arrival to insufficient hydrogen charging stations. The limit distance for arrival within a specific time was analyzed by applying the average vehicle traffic speed(23.1km/h, Seoul Open Data Square) in 2022 to three categories: 3,850m(10minutes), 5,775m(15minutes), 7,700m(20minutes). In order to minimize conflicts over the installation of hydrogen charging stations, special standards of the Ministry of Trade, Industry and Energy applied to derive candidate sites for additional installation of hydrogen charging stations among existing gas stations and LPG/CNG charging stations. Result: As a result of the analysis, it was confirmed that accessibility was significantly improved by installing 5 new hydrogen charging stations at relatively safe gas stations and LPG/CNG charging stations in areas where access to the existing 10 hydrogen charging stations is weak within 20 minutes. Nevertheless, it was found that there are still areas where access remains difficult. Conclusion: The location allocation model is used to identify areas where access to hydrogen charging stations is difficult and prioritize installation, decision-making to select locations for hydrogen charging stations based on scientific evidence can be supported.

점포선택에 영향을 미치는 선행변수들을 규명한 기존 연구들은 주로 점포 방문행동에 초점을 두고 진행되어 왔으나, 이러한 점포 방문행동이 과연 실제 구매행동으로까지 이어질 것인가에 대한 연구는 매우 제한적으로 이루어져 왔다. 본 연구에서는 관찰 자료를 이용하여 점포선택의 단계를 점포방문행동과 실제 구매 행동으로 분류한 후, 이들 각 단계에 영향을 미치는 요인들을 탐색적으로 실증하는데 그 목적이 있다. 소매점포를 대상으로 수집된 관찰 자료를 이용하여 분석한 결과, 경쟁점포의 수를 제외한 유동인구, 소매점포의 시계성과 같은 소매점포의 입지요인과 점포의 크기, 가판대 설치, 판촉 행사와 같은 소매점포의 마케팅 요인이 점포방문행동에 유의한 영향을 미치고 있는 것으로 나타났다. 또한 점포방문행동이 실제 구매동향에 미치는 영향력은 주효과뿐만 아니라 상품구색과 같은 점포내부요인과의 상호작용효과가 존재하는 것으로 밝혀졌다. 끝으로 이러한 결과의 이론적 및 실무적 시사점이 논의되고, 연구의 한계점과 미래의 연구방향이 제시되었다.

전주시의 도심 내에 고층건물의 건설전과 후의 풍속변화를 알아보기 위한 풍동실험을 통하여 다음과 같은 결론을 얻을 수 있었다. 고층건물의 건설은 도심주변의 풍속변화에 절대적 영향을 끼치는 요소인 것으로 파악되었다. 특히 건설 후에 최소 50% ${\sim}$ 최대 90%까지 풍속이 감소하는 부분이 발생하고 있다는 점은 고층건물과 같은 인공구조물의 건축과 입지가 주변의 기류변화가 급격한 영향을 주는 요소인 것이다. 이는 해당입지를 중심으로 바람의 원활한 소통이 발생하지 않아 국지적으로 도시기온이 신선한 바람의 흐름에 영향을 받지 않아 온실효과와 같은 현상을 발생시키게 되며, 이는 결과적으로 국지기온의 상승과 같은 문제를 발생시키게 됨을 의미하는 것이다.
