The growth and development of Gwangyang city was a result of the POSCO Gwangyang Works, and Gwangyang city is one of typical firm citys in Korea. The objective of this study is to identify and examine the change of migration and population structure in Gwangyang city from 2001 to 2010. Since 1981, total number of population of Gwangyang city increased from 78,478 in 1981 to 145,512 in 2010. The population structure by age was changed with population increase since 2001, and 30-40 aging group was 35% of total in 2010. During 2001-2010, the netmigraion showed -2,925 people, however, the number of inmigrants were overtaking the number of out-migrants since 2008. The most common reason of in-migrants was occupation(49.5%). Factors influencing Gwangyang City's population growth and oversupply are the location of POSCO Gwangyang Works and steel-related enterprises, opening and construction of Gwangyang container berth, the related development projects and establishment of Gwangyang Bay Area Free Economic Zone, and the local policies of Gwangyang City connected with these large-scale national projects. As a result, the number of manufacturing-related businesses increased due to various regional development projects conducted in Gwangyang City, and the growth of the business continued to increase due to the increase of younger people and births.

Sedimentological investigations on surface and suspended sediments were performed in Kwangyang Bay of the middle South Sea in order to reveal recent changes in depositional environments concerning anthropogenic influence. A variety of coastal developments caused the texture of the surface sediments to become distinctively finer, particularly in the southwestern part of the bay. Accordingly, the westward lining sedimentary facies was somewhat simplified from triple-mode distribution to the dual-mode one by the construction of POSCO. This east-west distribution to the sedimentary facies has recently graded into the north-south distribution by further construction of other industrial complexes including Kwangyang Port. The prominent textural changes in surface sediments are most likely associated with weakening of tidal currents related to the developments which is anticipated to be .still continued. The distribution and flux estimation of suspended sediments suggest a noticeable import of fine particles into the bay predominantly through a northern entrance rather than the southern entrance. The movements of suspended sediments in the water level near the seabed prevailed over those of the mid and surficial levels.

The three cities, Yeosu, Suncheon, and Gwangyang, in located in Gwangyang Bay which functions as a representative coastal industrial area in Korea, form a single functional area of living, municipality, and economy. In this regional context, some local merchants and scholars are promoting a inter-municipal cooperation of three cities. This study analyzes how the group of specialists perceives and evaluates the inter-municipal cooperation of three cities. The group of specialists highly evaluate the potential of future development of Gwangyang Bay region, and the relevance and necessity of feasibility of inter-municipal cooperation of three cities. It is estimated that the inter-municipal cooperation of three cities would need 8.3 years for its full-fledged shape. In order to accomplish the inter-municipal cooperation, the sharing the development vision of Gwangyang Bay region and the understanding and consent of the residents for the inter-municipal cooperation are suggested as the most important factors.

The variation of flow pattern caused by the topographical change of Kwangyang bay, is analyzed using the numerical tidal model for the depth-integrated two- dimensional long wave equation. The results of study are as follows. Due to pier construction, the area of water surface is deceased and the water inflow into the Kwangyang bay is reduced. For this result, at the outer bay of Myo island, the tidal range is slightly increased. And at the inner bay, water level is dropped generally, and especially at the time of low water tide, the phenomena of water level drop obviously appears. According to the variation pattern, flow velocities is lower than those of non-construction condition over the Kwangyang bay. But at the channel(from Kwangyang east stream) flowing into the east Kwangyang bay, for the contraction of channel profile, flow velocity is increased. The study based on the 100 year frequency design flood discharge from Sueocheon(river) and Dongcheon(river) which are flowing into the bay and Seomjin River flowing along the boundary of the bay is also performed. During the spring tide condition, the results showed the rise of water level about 1.2 m at Seomjin River Estuary and 0.3 m at inner bay is occurred.

정부는 최근 인천, 부산, 광양 등 3개 지역 경제자유구역청을 조직$\cdot$인사$\cdot$재정 등에서 자율성과 독립적인$\cdot$허가권을 행사하는 특별지방자치단체로 격상키로 하였다. 외자유치를 통한 원스톱 행정서비스를 제공하기 위해서다. 현재는 외자유치시 각 상급 지자체를 돌아다니며 인허가를 받아야 하기 때문이다. 하지만 특별지자체는 통상의 지자체와 구별되기 때문에 상위 단체의 규제를 받지 않고, 외자유치 등의 특수 목적을 위해서는 최대한의 자율적 권한을 갖게 된다. 이렇듯 정부에서도 경제자유구역청에 많은 관심과 힘을 쏟고 있다고 할 수 있다. 3개 지역의 경제자유구역청 중 가장 왕성한 활동을 펼치면서 외자유치에 모범이 되는 곳이 있다. 바로 광양만권경제자유구역청. 지난해 3월에 개청되어 타 경제자유구역청보다 늦게 출발하였지만 그 결과는 정 반대다. 광양만권경제자유구역청의 초대 청장으로 부임한 백옥인 청장은 포스코터미널 등 8개 업체로부터 9034만달러의 투자를 유치하고 국내외 15개 업체와 2조 720억원에 달하는 투자의향서를 교환하는 등 광양만권을 발전시키기 위해 노력하고 있다. 나아가, 광양에 대한 국제 인지도를 높이고 도로 등 SOC를 확충해 기본적인 투자환경을 조성해 가면서, 동북아 경제 및 물류 거점도시로 발돋움하기 위한 구체적인 계획을 하나하나 펼쳐 나가고 있다.

With the change of global production network, the establishment of new strategy in gwangyang port is required. Especially, the trade pattern has been concentrated to Northeast Asia region according to economic growth of the Asia including China, Japan, and Korea. Hence, Gwangyang port that have price and service competition have to meet of the need of Northeast port alliance and to compete against other countries in variable trade environment. Therefore, the objective of this study is to propose the port alliance strategy in order to promote the growth of Gwangyang port. For the purpose of the Logistics business model in Gwangyang port, we provided the direction of the Northeast port alliance and candidate ports in China and Japan.

The purpose of this study is to examine the causuality among export and import trading volume of port of Busan, Kwangyang, Incheon and to induce policy implications. In order to test whether time series data is stationary and the model is fitness or not, we put in operation unit root test, cointegration test. And We apply Granger causality and impulse response and variance decomposition based on VECM. The results indicate that the trading volume of port of Busan is not largely influenced by that of port of Kawangyang and Incheon, but the trading volume of port of Kawangyang and Incheon is largely influenced by other ports including port of Busan. The result suggest that government has to focus on policy that the port of Kawangyang and Incheon can raise its own competitiveness in the world market.

This study suggests a development direction by comparing the cargo throughput of the port of Yeosu-Gwangyang during 2007-2015 with that of domestic ports. It derived a concentration index (HHI) of cargo throughput in domestic ports by Yeosu-Gwangyang port docks, shipping companies, and abroad regions. The main results were as follows. First, in terms of total cargo handled, the port of Yeosu-Gwangyang was second only to the port of Busan, and the HHIs for the past nine years were relatively low. Second, the port of Yeosu-Gwangyang ranked first for total import and export cargo throughput, showing relatively stable HHIs from 2007 to 2015. Third, the HHIs of container handling performance by national shipping companies showed stable levels below 1,800. Fourth, there were no regions where cargo volume was noticeably concentrated in the port of Yeosu-Gwangyang, and it showed cargo throughput across various abroad regions. While changes in national shipping companies are expected after the Hanjin Shipping Crisis, there should be no serious concern regarding the dependence of the port of Yeosu-Gwangyang. It is expected to develop further by realizing the full use of all its facilities, diversifying the tenants in the Yeosu-Gwangyang area, and improving the demurrage rate.

This study investigates the behavioral characteristic difference of the container volumes of three ports-Gwangyang, Incheon, and Pyeongtaek-Dangjin. All series span the period January 2003 to December 2011. I first test whether the series are stationary or not. I can reject the null hypothesis of a unit root in each of the level variables and of a unit root for the residuals from the cointegration at the 5 percent significance level. I hitherto make use of error-correction model and find that Gwangyang port is the slowest in adjusting the short-run disequilibrium, whereas the adjustment speed of Incheon is much faster than that of Gwangyang. The impulse response functions indicate that container volumes increase only a little to the negative shocks in exchange rate, while they respond positively to the shocks in the business activity in a great magnitude and decay very slowly to its pre-shock level. meaning that the shocks last very long. The accumulative response to the exchange rate increase of 20 won per dollar and the 5 point industrial production increase is the smallest in Gwangyang, no more than a half of that of two ports. The intervention-ARIMA models also forecast that Gwangyang port will have much lower growth rate than Incheon and Pyeongtaek-Dangjin port in trading volumes.
