한국경제에 있어서 운수통신 서비스 산업은 공공운수 등 공공부문과 민간부문이 동시에 공존하고 있다. 공공부문은 일반적으로 가격규제의 대상이 되며 적정수준의 정상이윤이 보장된다. 본 논문은 생산요소가격으로 구성된 마크업방정식을 설정하고 운수통신산업의 시계열 마크업을 추정하였다. 또한 자기회귀 시차모형을 이용하여 마크업의 생산요소가격 탄력성을 추정하고 마크업의 결정요소를 분석하였다. 실증분석결과, 마크업의 임금탄력도는 -0.07, 수입가격 탄력도는 -0.45 그리고 이자율탄력도는 -0.13으로 추정되었다. 따라서 본 논문은 운수통신산업의 규제정책에 있어서 수입가격과 이자율이 고려되어야 할 주요 변수임을 밝히고 있다.

Information and communication technology (ICT) is increasingly recognized as an important driver of economic growth, innovation, employment and productivity and is widely accepted as a main feature of development. During the last couple of decades, ICT sector became the most innovative service sector that affected the living standards of human beings all over the world. In the beginning of the $21^{st}$ century, some of the Asian countries made reforms in the ICT sector and spent an enormous amount for the progress of this sector. On the other hand, developed countries in the European Union (EU) faced different crises which badly affected the dissemination of this sector. Consequently, EU countries lost their hegemony in the field of information technology and resultantly, some of the emerging Asian countries like China, India, and South Korea got supremacy over the EU in this field. Currently, these countries have a strong IT infrastructure, R&D sector, IT research centers working for the development of ICT. Moreover, this paper investigates reasons for the shifting of the balance of digital power from Europe to Asia.

Optical wireless communication (OWC) systems are rapidly gaining popularity as effective means of transferring data at high rates over short distances. OWC facilitates rapidly deployable, lightweight, high-capacity communication without licensing fees and tariffs. Nevertheless, the performance of this new technology depends strongly on the atmospheric conditions and the characteristics of the link. In this work, we study the influence of these parameters on both the average (ergodic) capacity and the outage capacity of an OWC system over moderate to strong turbulence channels modeled by gamma-gamma distribution. Moreover, we compare the results that we obtain estimating the average and outage capacities.

This paper examines the effects of information telecommunication (IT) capital and R&D stock variation on the growth of Korean industry, using a time series approach. Most specifically, we apply the Granger causality and impulse response analysis to our examination of Koreas industrial growth, IT capital, and R&D stocks. The Johansen co-integration test is performed in order to analyze long-term relations among these variables. This research explores the way in which IT capital and R&D stocks variation from economic shocks affects the growth of Koreas industrial sector. The effects are ambiguous, however, across industrial sectors. An impulse response function analysis shows that the effects of IT capital and R&D stock fluctuations in each industrial sector are presented for different time periods.

There have been dramatic technology changes in telecommunication sector during last two decades. New application services like the introduction of international mobile services, fiber optical home services and satellite personal services are expected to play a major role in the whole field of telecommunication services. In the users' viewpoint, the proper selection and the efficient application of the specific telecommunication service among the various alternatives at hand are recognized as principle means for ensuring the whole business competitiveness. Despite the definite need for the telecommunication service selection strategies, very few researches have been reported in this field. In this paper, attempts are made to identify the companies' decision factors considered in selecting the telecommunication services, to draw the strategic dimensions and categorize each company with respect to the identified dimensions, and to finally find the characteristics of each strategic group in selecting the telecommunication service.

This paper is to investigate the relationship between international marketing and service quality, and the moderating effect of gender in that relationship. The data to make an empirical analysis were gathered from 269 workers in telecommunication sector. Multiple regression analysis revealed that (1) education was positively related with tangibility, reliability, responsiveness, empathy, assurance, and (2) internal communication was positively related with tangibility, reliability, responsiveness, assurance, and (3) delegation of authority was positively related with assurance. Hierarchical multiple regression analysis revealed that (4) compensation was more positively related with reliability in woman, and (5) employment security was more positively related with assurance in man.

The standard issue in the information and telecommunication industry is increasingly important with the rapid development of technology. This paper proposes an index model which can measure the degree of standardization in the Korean information and telecommunication field. We first classified ICT sector into 14 sub-sectors. Then for each sub-sector, we considered a set of important determinants to measure the level of standardization, and constructed a linear equation using this set of determinants. Finally we estimated the relative degree of importance of each determinant using the AHP methodology. The proposed model found that overall level of standardization in the Korean ICT industry is relatively low, and ‘IMT-2000 technology’ and ‘computer network technology’ among 14 sub-sectors are highly standardized sub-sectors. The validity of the proposed model was also partially proved using two different methods, holistic and historical approach.

Information and Communication Technology (ICT) has the potential to provide economic opportunities and help raise the social and political status of countries. For developing countries, ICT can be used as a tool for economic growth and social advancement in a short period of time. The benefits of ICT, however, are not only economic in nature. It can help improve professional skills, teaching quality, job creation, agricultural production, community involvement, and information use, personal relationships, and time use. These benefits are examples of how ICT has become an indispensable part of our lives. Myanmar is a developing country and is ranked low in the ICT Development Index. In terms of ICT development, Myanmar today is facing many issues such as a lack of telecommunication infrastructure, ICT awareness, electricity, and budget for ICT development. Among the economic reforms implemented by the recent government, the telecommunications sector has been opened up as a measure of economic reform. As a result of this reform, the telecommunications sector has been growing rapidly. Myanmar, however, remains behind other Asian countries. This paper discusses Myanmar's ICT infrastructure status, progress that has been made in the country's telecommunications over the last fifteen years, and the challenges that lie ahead.
