최근 정보통신기술의 발전은 지식기반 경제에서 국가 전체 산업구조의 고도화와 지속적 경제성장의 동력으로서의 역할을 증대시키고 있다. 본 논문에서는 최근 전 세계 경제의 핵심을 이루고 있는 ICT 산업과 관련된 시장과 수출 현황을 분석하고자 한다. 주요 내용에는 OECD 주요 국가 및 중국의 ICT 산업과 수출에 관련된 시장과 수출 동향 그리고 신흥 국가들의 ICT 산업과 수출을 대상으로 하는 시장규모와 수출 현황에 대한 분석이 중심을 이룬다 이러한 분석 내용은 향후 우리나라의 ICT 산업의 경쟁력 향상을 위한 자료로 유용하게 활용될 것으로 기대된다. Recently the advanced technology on information and communications affects on the national industry structure. In this paper we investigate the recent trend on ICT industry market size and exportation amount for the countries, whose countries are activated in ICT-related industry. In the investigation the countries to be included in OECD and some other countries are focused. The results to be investigated are usefully applied to the activation of ICT-related industry in Korrea.

In this study, we aim to analyze price impacts of a Newtown project on nearby housing markets in Changsin·Sungin Newtown in Seoul, Korea. Newtown project launched by Seoul Metropolitan Government in 2002, is a neighborhood redevelopment program addressing both housing shortage and deteriorating infrastructure. Using hierarchical linear modeling structured by transaction time, with monthly housing transaction data from January 2006 to April 2016, we investigate the effects of a Newtown project on housing prices within and outside of its boundary along the process of designation to withdrawal. In general, we found a positive influence of Newtown within area. In case of multi-family housing and apartment, the market transaction property value is higher by, on average, 12.2% and 16.6% respectively within the Newtown boundary, and –10.9% and 3.3% in the within-500m boundary, and –7% and –4.6% in the within-100m boundary compared to the specified control group. In transaction-time specific analysis of the effect, we found that the average price of multi-family housing within the Newtown boundary were higher by 30-40% than their counterparts before the Newtown designation, but fell down from that point, then the premium becomes negligible toward the withdrawal. On the other hand, in the 500m boundary we found that average price of multi-family housing were lower by 14-18%, but it rose up from the start(2006.1) to withdrawal. In case of apartment housing the prices were higher by 5-10% within the Newtown boundary. It also slightly fell down at the announcement of the designation by 10-20% in the 500m boundary(<500m, within 500m zone, excluding the Newtown) and 100m boundary(<1000m, within 1000m zone, excluding the 500m zone).

In this study, we aim to compare food establishments a major retail district(bal-dal retail area) and its extended area(gol-mok retail area) in Itaewon from 2001 to 2006. First, using Kernel density estimation, we delineate the boundary of those two areas, and second, using Kaplan-Meier method and Cox"s proportional hazards regression, we empirically analyzed differences of survival rates and factors(locational characteristics & restaurants characteristics) influencing hazards of restaurants in each retail district. As a result of Kaplan-Meier modeling, extended area(median survival time 2,304 days)has faced a higher risk of closing their business than their counterpart major retail district(median survival time 2,748 days). However, Cox"s proportional hazards model, with controlling various factors influencing the business operation, suggests the opposite that the extended trade area has been an advantageous location, as the hazard of closing business is lower by -29.9% than the one of the major retail district. Variables being franchise is common variable to impact the survival time in each retail district. On the other hand, variables such as reach, straightness, on the 1st floor(major) and distance to subway & main road, parcel slope(extended) are more likely to impact the survival time at each area. Based on findings of this study, we conclude that failure patterns of those two retail areas are not identical and different strategies should be utilized for risk-management using the aforementioned factors.
