Applying the dynamic shift-share analysis, this paper decomposes inflow of foreign direct investment (FDI) of Korea for the period of 2003-2012 into three components: world growth effect, industry-mix effect and competitive effect. Taking the group of developed countries as population for comparison, this paper finds that Korea has been lagging behind the group of developed countries in attracting FDIs, thereby having recorded negative aggregate industry-mix effects and negative aggregate competitive effects as well. However, the following industries have recorded positive competitive effects: textiles, chemicals, electrical and electronic equipment, motor vehicles and other transport equipment, hotels and restaurants and business services. Moreover, in the sub-period of 2008-2012, positive competitive effects have been recorded for most manufacturing industries. This reflects the fact that inward FDI into Korea has not been affected much by the financial crisis of 2009.

The population and employment of Cheongju have increased rapidly since the 1970s. This study examines the industrial employment change of Cheongju City and performs a shift-share analysis for the employment growth. The data used in this study are mainly from the 1985, 2000 and 2005 Census of Population and Housing. This study first explained the population change and industrial structure of Cheongju, then reviewed the development of shift-share models. Location quotients and specialization coefficients resulted from this study revealed the diversifying tendency in the urban industrial structure. Shift-share analysis employing the modified Arcelus model elucidated the favorable industrial mix and the competitiveness of industrial sectors. As a whole, Cheongju has advantageous industrial structure in comparison with that of the nation. All sectors of Cheongju except several services sectors grew faster than those of the nation and showed positive competitive effects. It is suggested to utilize more disaggregated industrial data in more fractured subperiod in order to pinpoint the competitive industries.

Based on the number of employees and sales of tourism establishments in Chungnam ares for the period from 2009 to 2013, this study analyzes the regional growth characteristic of tourism industry using dynamic shift-share analysis. The data used for this analysis are obtained from "The Census on Basic Characteristic of Tourism Establishments". This study decomposes characteristics of Chungnam Area tourism industrial structure into three components: national growth effect, industrial mix effect and regional share effect. The results help to well understand the development and the competitive situation of Chungnam area tourism industry.

무선 ATM망에서 다수 연결채널로부터 발생되는 트래픽의 서비스 질을 보장하고 한정된 무선 자원을 효율적으로 사용하기 위해서는 다중접속제어 기술이 중요한 설계요소 중 하나이다. 본고에서는 ATM 프로토콜 특성을 무선 구간에 까지 확장한 동적다중슬롯할당(DMSA: Dynamic Multi-Slot Assignment)기법의 단점 중 하나인 연결채널별 지연 성능의 차이에 대해 분석하고, 이를 해결하기 위하여 이동국으로부터 각 연결채널에 대해 전달되는 정보를 이용하여 중앙제어국에 가상큐를 도입하는 방안을 제안한다. 중앙제어국에서는 구성된 가상큐룰 이용하여 상향링크의 다음 한 프레임내 모든 타임슬롯에 대한 연결채녈 할당을 수행한다. 다양한 트래픽 소스에 대한 시뮬레이션을 통해 가상큐-동적다중슬롯할당 알고리즘이 기존의 동적다중슬롯할당 알고리즘에 비해 중앙제어국에서의 단순한 제어 부하만으로도 다수의 연결채널에 대해 균등한 설비스 질을 보장하고 지연 변이 특성의 성능 향상을 나타냄을 입증한다. 이러한 연구결과는 동종 혹은 이종의 트래픽을 가진 각 연결 채널에 대해 무선 구간의 분산 환경으로 인해 발생할 수 있는 불평등성을 해결함으로써 무선 ATM의 개념을 우선 ATM과 유사한 환경으로 분석할 수 있는 계기를 마련한 것으로 판단된다.

This study analyzes the effects of localities' competitiveness which can contribute to employment growth in industries, on economic development in the local jurisdictions. For this analysis, such competitiveness is measured by competitive shares calculated from the application of a shift-share method to the employment growth in industries each locality witnessed over the 1990s. And we use annual population growth rate and average annual per capita income (substituted by per capita head tax derived from income tax) of the early 2000s as variables of local economic development. The analysis targets 167 local jurisdictions in Korea for the employment growth in industries, and is mainly placed in a spatial econometric setting. The results of analysis are as follows : The competitive share of manufacturing has the effect of increasing annual population growth rate whereas that of construction has a negative effect on the population growth rate. As well, the competitive shares of manufacturing and of construction negatively influence average annual per capita income while that of community, social and personal services positively affects the income.

해양산업은 새로운 부가가치산업 및 신성장동력 산업으로 인식되고 있다. 특히 항만을 중심으로 클러스터를 조성하여 고부가가치를 창출하고 있다. 해외 선진항만들도 앞 다투어 클러스터를 조성하여 수익창출과 경쟁력 강화에 나서고 있다. 우리나라도 2015년 해양산업클러스터 조성과 육성에 관한 법률을 제정하였다. 따라서 각 지역별로 어떤 해양산업이 비교우위에 있는지 파악하는 것은 해양산업클러스터를 통한 집적화 전략을 수립하는데 매우 중요하다. 따라서 본 연구에서는 남지역을 대상으로 해양산업 구조를 분석하였다. 먼저 해양산업 분류에 대한 기존 문헌분석을 실시하여 해운 물류업, 조선업, 수산업, 해양관광업, 기타업 5개의 대분류와 21개 중분류, 84개 소분류로 해양산업을 재분류하였다. 재분류한 해양산업을 기준으로 입지계수와 변이할당분석 기법을 활용하여 전남의 해양산업 구조를 분석하였다. 이 연구결과는 향후 전남지역 해양산업클러스터 구축 시 전략수립에 기초자료로 활용할 수 있을 것이다.

Applying the shift-share analysis, this paper decomposes FDI inflow into Korea for the period of 2003-2006. The paper finds that Korea has been lagging behind the world average in absorbing inward FDI, thereby recording negative aggregate industry-mix effects and negative aggregate competitive effects as well. However, the following industries have recorded positive competitive effect: electrical and electronic equipment, motor vehicles and other transport equipment, hotels and restaurants, transport, storage and communications, finance, and business services. In a nutshell, Korea is revealed to have competitive advantage in absorbing inward FDI in a few manufacturing industries and most of service industries. Government policies should accordingly be focused on these industries to encourage more inward FDIs.

This paper examines the export structure of Gwangyang Port and evaluates its comparative advantage from 2005 to 2016 using the Comparative Advantage by Countries (CAC) index. It is found that: (i) Gwangyang Port has a comparative advantage in HS 39 and HS 28, an unstable comparative advantage in HS 29 but a comparative disadvantage in HS 72; and (ii) 4 items have the common features of losing their comparative advantage. Constant market share analysis allows one to evaluate why the exports of one region may grow faster than world exports. This consists of the commodity composition effect, the scale effect, and the competitive effect. Constant market share analysis shows that the commodity composition effect influences exports negatively while the scale effect does exports positively. Shift-share analysis can help evaluate the change in a region's performance relative to the nation over a given period of time. The result indicates that HS 28 has not only favorable industrial mix effect but high competitive share effect, while HS 29 has unfavorable industrial mix effect as well as low competitive share effect. This paper also reveals that industrial mix effect of HS 39 is positive but its competitive share effect is negative, whereas the former is negative but the latter is positive in case of HS 29.

Ports in Korea have been increasing in terms of volume while they have performed functions and roles such as industrial ports in promoting industries of their hinterlands as well as commercial ports supporting imports and exports. Nevertheless, specialization degree is different from port to port by cargo type and the changes in cargo volume. This study aims to analyze the structural changes and the degree of concentration and specialization by cargo type and port between 2001 and 2020. Top 10 ports were analyzed in terms of traffic volume by categorizing liquid, dry, general cargo and containers. HHI(Herfindahl-Hirschman Index), LQ(Location Coefficient), and shift-share analysis were employed in order to identify the degree of concentration, specialization and changes in cargo volume by port and cargo type. As a result of the analysis, the degree of port concentration and specialization for each cargo of 4 categories have maintained a high level, and no significant difference were found in fluctuations over the past 20 years. As a result of calculating the flucation of cargo volume through the shift-share analysis, the growth rate of liquid cargo was high in Yeosu Gwangyang Port, Pyeongtaek Dangjin Port in dry cargo, and Busan Port in general cargo and container ports. The result implies that it is not expected that the structural changes including degree of cargo concentration, specialization and relative fluctuation of cargo volume is significant in Korean ports in the future since the effects of economies of scale and clustering were achieved to the great degree.
