Since the CBD(Conservation on Biological Diversity)'s 10th Conference of the Parties adopted the protocol on access to genetic resources and benefit sharing in Nagoya 2010, the importance of endangered species studies such as habitat distribution, protection and management have been more emerged. Corylopsis coreana, an endangered species in Korea, was isolated nationally and has been damaged by anthropogenic factors. In this paper, we identified the factors affecting C. coreana habitat at the national scale and regional scale using National Survey of Natural Environment and predicted the distribution of C. coreana. Annual precipitation, precipitation of wettest quarter, temperature seasonality and Digital Elevation Model(DEM) were derived as important factors at the national scale, and precipitation of wettest quarter, DEM and solar radiation on spring were identified as important factors at regional scale. Colylopsis distribution was affected by an effect of climate significantly at the national scale, and by additionally the microclimate and topography at regional scale. These findings will be used as the basis on habitat conservation and restoration plan and climate change.

본 연구에서는 카셰어링 이용특성자료 및 GIS를 활용하여 입지특성과 관련된 도시 및 지역적 사회경제에 대한 DB를 구축하였으며, 주성분분석을 통해 잠재변수를 도출하였고 요인점수를 활용한 다중회귀분석을 통해 영향변수의 의미를 살펴보았다. 업무중심지역 및 역세권지역, 대학교인근지역에서의 활용도가 높았고, 특히, 전기차에 대한 관심도가 카셰어링 이용도에 영향을 미치는 것으로 파악되었다. 한편, 금융기관이 집중된 지역 및 영업용(택시)차량 배치가 많은 지역에서는 이용이 제한되는 것으로 나타났다. 본 연구의 분석결과는 향후의 카셰어링의 활성화와 공유가치에 대한 시민의 이해도 향상과 소유에서 공유로의 발상전환에 기여할 것으로 판단된다.

Purpose - The purpose of this study is to propose strategies of improving efficiency of 20 listed port companies in China based on analysis of their input-output indexes from 2014 to 2018. Research design, data, and methodology - In this paper, the relevant input-output indicators of 20 listed port companies in China from 2014 to 2018 were adopted. Data derived from the company annual reports announced by Shanghai stock exchange and Shenzhen stock exchange. Comprehensive efficiency and pure technical efficiency were measured from output perspective by DEA and Malmquist index, and efficiency changes and regional efficiency were analyzed. Result - The results showed that the efficiency value of 20 listed port companies in China fluctuated and increased during 2014-2018, regional efficiency was unbalanced, and change of MPI was influenced by internal factors and external factors. Listed port companies affected by internal and external factors needed to make appropriate response to internal and external factors. Conclusion - The research conclusion can provide important reference information about management and planning for port companies in China and related areas. However, this paper is limited to the availability of data. So the improvement scheme for listed companies in inefficient regional ports needs further study, such as using AHP method.

본 연구는 그동안 지역정책 전략을 지배해 온 지역경쟁력 개념이 저성장과 위기 상존 기조가 지배하는 오늘날 지역정책 전략으로서 한계를 갖고 있다는 문제의식을 토대로 보다 지속가능하고 통합적인 새로운 지역발전정책 전략을 위한 새로운 지역회복력 개념의 의미와 적용방안을 사례연구와 함께 고찰하였다. 이론적 고찰을 통해 본 논문은 대내외 여건의 급속한 변화에 직면한 지역변동을 이해하고 새로운 지역발전전략을 모색하는데 지역회복력이 유용한 개념이라는 점을 확인하였으며, 더 나아가 지역회복력의 측정과 요인에 대한 문헌분석을 통해 향후 지역회복력 관련 연구를 위한 기본방향도 설정하였다. 또한 시론적인 사례분석을 통해 우리나라를 대표하는 수도권과 동남권의 지역회복력 추이와 그 과정에서 장소와 스케일에 따라 그 패턴과 경험이 차별적이며, 지역 내 경로의존적으로 형성된 산업구조와 지역의 경쟁력 효과가 지역회복력 패턴을 이해하는데 유의미함을 파악하였다.

Education is widely recognized one of main sources for growth. This paper attempts to incorporate the general recognition into formal regional growth model. The model structure is largely neoclassical. It produces a single good with the two factors, educated labor and non-educated labor, via a constant return production migrating to the region with the higher real wage. The educated labor in a region is accumulated by two sources, migration and physical education capital, while the non-educated labor is by only migration. The paper shows that regional growth equilibrium is characterized as a saddle point. This indicates the presence of the minimum threshold size that must be overcome before a region may grow. It contrasts sharply with results obtained in regional growth models. The paper suggests that regional growth is determined less by the technical characteristics of regional production function characteristics of regional production function but by the stock combination of educated function but by the stock combination of education labor and non-educated labor. Based on this result, the impact of agglomeration economies on regional growth is explored. It is by phase diagram demonstrated that the presence of agglomeration economies do not always lead a region to growth since there still exists the minimum threshold even in the presence of agglomeration economies.

본 연구는 우리나라의 대표적인 혁신클러스터인 대덕연구개발특구를 대상으로 혁신클러스터의 성장에 미치는 영향요인을 제도적 물리적 사회적 구성요인으로 구분하여 고찰한 사례연구이다. 특히 이들 구성요인은 지난 15년간 대덕연구개발특구의 변화와 발전을 통해 성장에 영향을 미쳐왔으며, 향후에도 지속적 발전에 중요한 영향요인이 될 것이다. 이러한 측면에서 본 연구는 보완적으로 대덕특구의 혁신활동에 있어서의 혁신주체들의 위상 변화 및 환경, 제도 정책변화 등을 제도적 물리적 사회적 구성요인 측면에서 다각적으로 살펴보았다. 또한 도출된 대덕특구의 성장에 영향을 미치는 구성요인에 대해 AHP분석 방법을 통해 내부 혁신 주체들이 인식하는 중요도를 측정하였다. 본 연구는 대덕특구를 대상으로 장기적인 관점에서 혁신클러스터의 성장에 영향을 미치는 구성요소들을 제시하고 그 중요도를 도출함으로써 지역혁신 및 혁신클러스터 정책적 시사점을 제공한다.

In recent years, the natural damage associated with flood disaster has been dramatically increased. However, there is no rational method which reflects urban characteristics to estimate the regional safety assessment for flood disaster. The purpose of this study is to develop the regional safety assesment model for urban flood. Flood risk and reduction assesment were estimated by using the linear sum of the Z score of the assessment factors and the weight value of each factor from the expert survey data. And then the regional safety assessment was estimated by subtracting reduction factor value from risk factor value. GIS tool was used to estimate the factor assesment and integrated regional safety. This study can be used to determine the priority of flood protection project, execute the flood insurance and establish the urban plans and the flood mitigate plan.

This paper attempts at analyzing the urban dynamics in Northeast Asia by looking at major forces transforming the regional structure of Northeast Asia. Trade and foreign direct invest-ment are identified as two principal channels of increasing economic interdependence in the region. In addition, macro development strategy and infrastructure policy are another set of determining factors for changes in the regional structure of Northeast Asia. To examine the role of cities and inter-city linkages, the paper first tries to identify major urban centers and urban hierarchy in Northeast Asia. Secondly, it examines the prospects for inter-city network formation. Against these anticipated changes in the regional structure and inter-city networks in Northeast Asia, the paper discusses about the future of Korea as well as the role of Koran cities in the regional economy of Northeast Asia.

Regional production structres are investigated through an estimation of three-input(labor, capital and material) translog cost function. The estimation uses the pooled data in which time series data of 1970-1990 are combined with cross-sectional data corresponding to firm sizes. The empirical finding are the following: (1) the factors are Allen substitutes each otner in general except Pusan and a couple of regionss, and (2) estimates are very small in its absolute value irrespective of the regions. The low elasticity estimates of this study implies that substitytability among the three inputs are very weak in the regional manufacturing production compared to that in the national production. Seoul-Kyungki metropolitan area produces not only the smallest elasticities but relatively stable estimates without much fluctuation between the sub-regions of the area.

The main objective of the present study is to find out which factors affect coresidence between older Korean parents and their adult children and to examine the regional patterns of the phenomenon. The 1980, 1995 and 2005 Korea census data are used to investigate the determinants of two types of parent-child coresidence. The two types are coresidence with married adult children and one with unmarried adult children. The study takes advantage of the multilevel mltinomial logit model, allowing the model to capture regional differences. Findings from the study are: (1) Korean parents' coresidence with their married adult children and one with their unmarried adult children are distinctive in their determinants; (2) variables related to wealth or economic status are positively related with possibilities of both types of coresidence; and (3) considerable regional differences in the possibility of coresidence do exist among regions in Korea.
