  • This paper analyzes the size of direct and indirect impact of the information and communication technology(ICT) producing sector to the Korean economic growth We first divide the entire economy into the ICT producing sector and the ICT using sector, and estimate the contributions to the economic growth by each sector. We also try to answer the question on what the possible causes of the ICT producing sector's contribution are to growth. In oder to find the answer, we focus on the change in the relative prices of ICT products produced in the ICT producing sector and examine the long-term relations among the relative prices of ICT products, the ratio of ICT products used in the ICT using sector as an intermediate input, and the output of the entire economy. We find that the overall economic growth has been weakened but the ICT sector's contribution to the growth has increased. Specifically, the indirect contribution of the ICT producing sector, through the ICT using sector, to economic growth was greater than the direct contribution of the ICT producing sector itself. We also find a stable, long-term negative relation between the relative prices of ICT products produced in the ICT producing sector and the ratio of ICT products as an intermediate input in the ICT using sector. In addition, the decrease in the relative prices of ICT products produced in the ICT producing sector increases the use of ICT products in the ICT using sector and the output of the entire economy. These findings can be interpreted that the price decrease in the ICT products improves the production efficiency in other sectors and helps directly and indirectly, accelerating growth of the entire economy.

  • This study analyzed the impact of ICT usage on elementary and secondary school students on the result of ICT literacy levels for finding out why most of students were 'normal' or 'basic'. As a result, we found out that the learning action, information searching and leisure action of student using ICT had correlation with ICT literacy level. The higher the rate using ICT for learning, information searching and leisure, the higher the ICT literacy level of student. But the higher the rate using ICT for communication, the lower the ICT literacy level of student. Accordingly, we proposed the policy not to increase simply ICT using of student, but to teach how to use ICT for learning and information searching.

  • The phenomenon of increasing aging population is one of the crucial social and economic issues in these day. In this paper, drawn from the industrial application cases and relevant literatures, we present the typology of ICT convergent applications targeted for silver generation, referred as silver ICT. Subsequently, the contributional value of ICT as the enabling technology is estimated. We firstly conduct keyword search to collect currently used silver ICT applications. Secondly, drawn from the social welfare literature, we organize distinctive needs of the silver generations. Then, on the basis of task technology fit framework, typology of ICT enabled silver applications is organized through the fit of ICT in the sense of fulfilling those silver needs. Finally, using the industry input-output table figures, potential ICT contributions for silver ICT are estimated. The proposed silver ICT typology and ICT contributions provides useful insights for further research in the area of ICT convergence and silver market research.

  • The purpose of this study is to examine an organizational ICT(Information and Communication Technology) performance by ICT investment and policy consistency of government organizations. As the rapid development of ICT is becoming an essential element of social culture, the ICT operation of bureaucratic government also is becoming important. The central government has invested substantially new ICT for improving the quality of nationwide service and to promote administrative efficiency. However, various departments of government occur frequently duplication investments of ICT, and budget conflicts between organizations caused difficulties in maximizing ICT competency. I will confirm the ICT operational performance by ICT investment behavior and organizational work competency as well as the significance of ICT policy consistency. The method of study used a structural equation. The research model set ICT investment behavior as independent variables, organizational work competencies and policy consistency as mediations, and operational performance as dependencies. As a result of the research, New ICT interests show negative effects that caused work change between government organizations and government-funded body. But, New ICT convergence shows positive effects on increasing the two competency variables. The two competency variables show negative effects that caused changes in ICT policy consistency and show no impact on the ICT operational performance. The ICT policy consistency shows a positive effect on enhancing ICT operational performance. The study contribution explain updated the contingency theory and because the ICT policy consistency is essential, negotiation between government organizations will be important. Future research will require a qualitative study through interviews in government organizations about consistency enhance of ICT policy.

  • President Park Geun-hye Administration has established the Ministry of Science, ICT and Future Planning (MSIP) to build a creative economy using Information and Communication Technology (ICT). July 2, 2013, The National Assembly has legislated the special act on the ICT promotion and convergence so called special ICT Act. This special ICT Act has reduced the legal basis through legislative process and departmental agreement. Therefore many experts worried that since the MSIP's key functions and roles are being reduced, there will be a limit to the MSIP's endeavor for the advancement of science technology and the ICT promotion and convergence. The establishment of the Agency, together with the formation of 'IT Strategy Committee', is considered to be one of the core items of the Special Act on ICT. MSIP originally planned to integrate the ICT R&D functions scattered across many governmental organizations, including Korea Communications Agency (KCA), KEIT and Korea Creative Contents Agency (KOCCA), into the Agency to separate the national ICT R&D from private R&D and streamline the process of 'discovery-selection-evaluation-commercialization'. The analytical results in this study are supposed to the establishment of efficient ICT governance systems as the practical strategies to actively cope with the changes of ICT convergence environment. It is also expected to the revision on the special ICT Act in the ICT budget and governance. Therefore, MSIP should cover research and development (R&D) as well as major ICT promotion functions to a creative economy.

  • We investigate the effect of ICT capital on the demands for labor and energy in manufacturing and electricity gas water industries of Korea, US, and UK. Assuming ICT capital, non-ICT capital, labor, electricity, fuel, and material as input factors for manufacturing and ICT capital, non-ICT capital, labor and energy material as input factors for electricity gas water industry, we estimate the Morishima elasticities of substitution. Considering the relative price changes of input factors, ICT capital has substituted labor in manufacturing and electricity water gas industries of the three countries. ICT capital has substituted both electricity and fuel in US and UK manufacturing. Although ICT capital has substituted electricity and fuel each other in Korean manufacturing, ICT capital is unlikely to decrease the demands for electricity and fuel when considering their relative price changes. ICT capital has substituted energy material in electricity gas water industries of the three countries.
