This paper conducts the input-output structural decomposition analysis on the growth of ICT industry during year 2000~2019. The novel feature of this study is to dissect the economy-wide collective growth contributions into industry by industry contributions. The main results are as follows. First, the growth of ICT manufacturing industry has excessively depended on its own export and import-substitution of intermediate goods, while the growth of ICT service industry has heavily depended on its own domestic final goods demand. Second, for the growth of ICT manufacturing industry, its own contribution is about 79%, and the contributions of non-ICT service and manufacturing industries respectively are 11% and 9%, but the contribution of ICT service industry is only about 1%. For the growth of ICT service industry, its own contribution is about 61%, and the contributions of non-ICT service and non-manufacturing industries respectively are about 33% and 5%, but, surprisingly, the contribution of ICT manufacturing industry is less than 1%. Third, the contributions of non-ICT manufacturing and service industries to the growth of both ICT industries have been done mainly through increase in export and domestic final goods demand together with change in the structure of input technology.

This study is to analyze the impact of the absorptive capacity and information technology (IT) on firms' innovation. The absorptive capacity is measured by R&D investment intensity, R&D manpower concentration, and the firm's size. We try to see the interaction effects between the absorptive capacity and IT usage on firms' innovation. We also look into the differences of the impacts between manufacturing industry and service industry as well as IT industry and service industry. We found that IT and R&D intensity have stronger interaction effect on innovation in manufacturing industry than in service industry, which shows that IT plays a more important role in the accumulation of knowledge in R&D activity in manufacturing industry. Contrarily, in service industry, IT and R&D manpower concentration has significant interaction effects on innovation. This means that the role of IT in service industry is sharing knowledge and experiences among employees in service industry. The interaction effect between firm's size and IT has positive impact on innovation in manufacturing industry, while it has negative impact on innovation in service industry. Finally, we found that the interaction effect is statistically significant in non-IT industry, while it is not statistically significant in IT industry.

This study compares and analyzes the effects of GVC participation on export competitiveness in manufacturing and service industry in 36 OECD countries and 28 non-OECD countries. According to the statistical analysis result, the GVC participation had a negative impact on export competitiveness in manufacturing industry, while it had a positive impact in the service industry. In the case of the manufacturing industry, participation toward the backward GVC had a positive impact on export competitiveness before the financial crisis, besides, participation toward the forward GVC had a positive impact on export competitiveness. In the case of the service industry, export competitiveness through forward GVC participation has increased since the financial crisis has occurred, and backward GVC participation was estimated to have a negative impact on export competitiveness. The results of this study implies that, to secure export competitiveness, a converged approach of the manufacturing and service industries to upgrade the global value chain is needed.

Global economy these days is characterized with an unlimited competition due to Globalization and Information Age. Expansion of E-business accelerates informationized and globalized society and also intensifies market competition. As a result, global economy gradually develops to knowledge-based economy, and Business Service Industry becomes essential to the production increase in the manufacturing industry as well as its high added value comes into the spotlight as one of rapidly growing business industry. Business Service Industry has not yet been academically established, however, it may be defined as the industry of which production is a mediating service in the production process rather than in the final consumption. The export of the manufacturing industry has traditionally played mainstream role in Korea where economic development has been centered on the manufacturing export. However, as with increasing emphasis on the role of service sector and highly developed industrial field in the national economy, not only the relationships between manufacturing industry and service industry becomes rapidly more involved, but also the importance of highly competitive service industry becomes emphasized in accordance with open global economy after WTO system takes off. Now it is time we come to the realization that service is in the center of national competitive power as a result of global door open in all service industry.

In the last ten years, manufacturing companies like GE, IBM, Motorola and service companies like GE Capital and CITIBANK have realized that Six Sigma has standed for quality reform movemant. Six Sigma management which makes the critic effects on the quality management have enlarged and applied office indirect work process and service department as well beyond question manufacturing process. Then Can Six Sigma application methodology from manufacturing industry be applied to service industry without transformation? Can Six Sigma be applied on improvement of Information system quality which is the critic key figure of current successful companies? These questions would be resolved by conducting researches about application and evaluation of Six Sigma on manufacturing industry and service industry. This paper will furnish information of Six Sigma's new function for future business situation through comparing those researches

This paper analyse the economic inducement effects of aviation industry using Input-Output Model. For measuring economic inducement effects of aviation industry on korean economy, this paper divides air transport industry as two - manufacturing industry and service industry. we also use Input-Output Table of year 1990 through 2003 from Bank of Korea. Empirical results tells that aviation manufacturing industry have high product inducement effects to national economy although its low value-added coefficient such as 0.486 for aviation manufacturing industry and 0.447 for aviation service industry. public R&D doesn't have much effect to each of aviation industries.

Product-related services in manufacturing industry are different from typical services in service industry. Product-related services ensure proper product functioning, provide additional repurchase, and offer attractive margin Product-related services in manufacturing industry are not core activity but taking supporting roles, while services in typical service industry are core parts. The purpose of this study is to investigate the role of communication in linking IT and product-related logistics service in manufacturing industry. The relationships among IT, communication, logistics service and business performance are explored using a path analysis. The empirical research reveals that higher degree of IT usability leads to increased communication, and in turn, communication affects logistics service, and ultimately business performance. In addition, this study shows communication plays an intermediate role in linking IT to logistics service.

With the introduction of the Internet in the 21st century, the manufacturing-oriented industry, so called EMS(Electronic Manufacturing Service) specialized in manufacturing only, is rapidly expanding. From the beginning of the year 2000, the EMS industry in advanced countries around the world, whereas a strong Motivation System in which a manufacturing related staff plays a main role, has began providing the source of competitiveness. And this industry is regarded as a core of management linking productivity directly to management performance. Thus, all the manufacturing sectors including not only the electronic industry but also mechanical industry in the future are observed to be divided into two industries; a Maker strategy industry focused on marketing and development, and a EMS industry specialized in manufacturing. Therefore, we need to evaluate whether the industries should continue to support the Manufacturers Strategy or attempt to change into the EMS industry However, with no approved evaluation standard on hand as to an actual EMS industry, in this thesis, we develop the EM(EMS-Maker) Chart in order to analyze both the Manufacturer Strategy and the EMS industries.

This study examines whether expenditures in information technology (IT) are associated with increases in the Tobin's q ratios a measure of organizational performance. It uses two groups of sample, Korean and American firms that disclose IT expenditures. For the all-firms group of each country, the association between IT expenditures and Tobin's q ratios is positive and statistically significant. But the association varies among industries. For Korean firms, IT expenditures appear to increase Tobin's q ratios for the machine and equipment manufacturing industry group (SIC3-2). IT expenditure ratio of this group as a percent of total sales is highest among the industry groups. For all service industry groups(SIC4&5), the estimated coefficient of IT expenditures is positive but statistically insignificant. For American firms IT expenditures in most of the manufacturing industry groups appear to increase only a little, if at all, for the Tobin's q ratios. But IT expenditures appear to have a greater impact on Tobin's q ratios for all service industries (SIC4-7). For three service industries tested (transportation and telecommunication- SIC4, financial- SIC6, consulting and other service industry- SIC7), the estimated coefficient of IT expenditures is positive and statistically significant. The evidence from both Korean and American firms suggests that IT expenditures in service industries provide a greater impact on an organizational performance than ones in manufacturing industry. To test whether service industries use a competitive strategy utilizing IT as a core competence, the samples ore divided into two groups, service and manufacturing industry. For Korean firms, both IT and R&D expenditures in manufacturing industry are associated with increases in Tobin's q ratios. But for service industry, the estimated coefficient of only IT expenditure is positive. For American firms, the estimated coefficients of both IT and advertising and R&D (ARD) expenditures in manufacturing industry are positive but the coefficient of only ARD is statistically significant. For service industry, the estimated coefficient of only IT expenditure is positive and statistically significant. The evidence may suggest that manufacturing industry uses both R&D and IT strategies to increase a competitive advantage but uses R&D strategy as a core competence. However, service industry uses IT strategy as a core competence to increase a competitive advatage.
