This paper is concerned with a comparative study on the economic effects upon the Korean economy by transport mode, ie road, rail, air, and coastal and inland water transportation between 1990 and 2000, using input-output analysis. The economic effects consist of backward and forward linkage effects, production inducing and import-inducing effects. The data employed for this study come from the Bank of Korea database for Input-Output structure of the Korean economy. The major findings in this study are, among others:(1) the power of dispersion(=backward linkage effect) of coastal and inland water transportation sector is the highest among the four transport sectors, while road cargo transport mode showed the highest the degree of sensitivity (=forward linkage effect); (2) rail cargo transport recorded the highest production inducing effects; and (3) air transport mode achieved the highest ranking in the import-inducing effects.

As the world economy has been changed into the knowledge-based society, all economic activities have globalized and intensified competition in the marketplace, and the forces of these changes are even more aggressively pressuring today's business. According to many businesses are focused on the core competence and various functions are outsourced by service providers, many firms pay heavily attention to business service. Although the importance of business service, domestic business service industry shows a low labor productivity. On the other hand, foreign business service companies in korea take a substantial portion of business service market. Thus, domestic business service needs to increase a competitiveness because of potential growth opportunities. This study attempts to find out the ripple effect of business service industry on other industry.

Korean government has initiated integrated-energy business (IEB) in Mokdong for energy conservation in 1983. Since then, IEB has been steadily expanding. This paper attempts to apply input-output(I-O) analysis to examine the economic effects of IEB. A static I-O framework is employed, focusing on three topics in its application: the impact of the investment of IEB on the production of other sectors and the inter-industry linkage effect; supply shortage effects of the IEB ; and the impact of the rise in IEB rate on prices of other products. The paper pays closer attention to IEB sector by taking the sector as exogenous and then investigating its economic impacts. The results can be widely utilized in decision-making about IEB policy.

This paper formulates a monopolistic competition model by incorporating Leontief product function into Dixit and Stigliz model to analyze and compare the effects of two environmental policy instruments-fuel efficiency regulation and environmental tax-on a market which reflects characteristics of international vehicle market. As expected, both policy instruments raise equilibrium market prices. The effect of fuel efficiency regulation on firm output, the number of firms, and industry output, however, depends on three determinants-the increasing rate of the ratio of consumer expenditure to the income, the increasing rate of fixed cost, and the increasing rate of marginal cost. On the other hand, the imposition of the specific environmental tax reduces the firm output, but does not influence the number of firms. If these two instruments are assumed to lead to the same increasing rate of marginal costs, the environmental tax reduces the firm output as well as the industry output more than the fuel efficiency regulation. And it will induce more firms to exit the market than the fuel efficiency regulation if the increasing rate of the ratio of consumer expenditure to the income is larger than the increasing rate of fixed cost.

In this paper, we analyze the economic ripple effects of technology related to the unmanned aerial vehicle industry by applying industry association analysis. Specifically, the effects of employment creation, value added inducement, sensitivity coefficient, and influence coefficient can be calculated, and implications for the analysis result are presented. As a result, the employment inducement effect was confirmed to be 10.017 persons per 1 billion won of investment. The value added inducement effect was much higher than the other manufacturing industry average (employment inducement coefficient: 2.285, value added inducement coefficient: 0.581) when the 1 won budget was added, resulting in 0.9771 won added value. In the unmanned aerial vehicle industry, the coefficient of sensitivity, which means the front chain effect, is 0.7870, which is lower than the manufacturing average (sensitivity coefficient 1.125), and the coefficient of influence, which means the backward chain effect, is 1.161, which is higher than the manufacturing average (influence coefficient: 1.116). Therefore, it is classified as the final demand manufacturing industry. This means that the unmanned aerial vehicle industry is an industry that is less affected by economic fluctuations and can be interpreted as an industry with a greater economic impact than other sectors. Based on these data, it can be used to establish the R&D investment direction policy of the unmanned aerospace industry.

This paper attempts to conduct a comparative analysis on the economic effects of integrated-energy and manufactured gas supply sectors. To this end, an input-output (I-O) analysis is applied using most recently published 2011 I-O table. In particular, the two sectors are specified as exogeneous to identify the economic effects on own and other sectors. Production-inducing effect, value-added creation effect, and employment-inducing effect are quantified based on demand-driven model. Supply shortage effect and price pervasive effect are analyzed employing supply-driven model and Leontief price model, respectively. The results show that production-inducing effect, value-added creation effect, and employment-inducing effect of integrated-energy and manufactured gas supply sectors are estimated to be 1.5461 vs. 1.0297, 0.4759 vs. 0.1941, and 2.2885 vs. 0.4053 respectively. Price pervasive effects of the 10% increase in integrated-energy and manufactured gas supply sectors are computed to be 0.0127% and 0.1585%, respectively. This information can be utilized in forecasting the economic effects of introducing integrated-energy or manufactured gas as a heating source and the impacts of a rise in price of integrated-energy or manufactured gas on price level of other sectors.

The government is planning to expand the bio-gas supply as a method for mitigating greenhouse gas emissions to deal with climate change. By means of a policy instrument, the government is considering an introduction of the Renewable Fuel Standard (RFS) whose targets include bio-gas. This paper attempts to look into the economic effects of expanding the bio-gas supply by applying an input-output (I-O) analysis using a 2011 I-O table. The bio-gas supply sector consists of liquefied petroleum gas supply sector and city gas supply sector, based on the tenets of introducing the RFS. The production-inducing effect, value-added creation effect, and employment-inducing effect of the bio-gas sector are analyzed. The supply shortage effect and the price pervasive effect are also investigated. The results show that the production or investment of 1.0 won in the bio-gas supply sector induces the production of 1.0539 won and the value-added of 0.1998 won in the national economy. Moreover, the production or investment of 1.0 billion won, supply shortage of 1.0 won, and a price increase of 10.0% in the bio-gas supply sector touch off the employment of 0.5279 person, 1.6229 won, and an increase in overall price level by 0.0183%, respectively.

Korean Shipbuilding industry takes 33.1% of world market. This shows that Korea is number 1 in shipbuilding. Also, this means the shipbuilding industry plays a significant role in national economic development. This Study attempts to analyse the national economic impacts of shipbuilding industry using an inter-industry analysis. The study investigates demand-driven model and the Leontief price model. Specifically, this study investigates production-inducing effect, value added-inducing effect and employ-inducing effect. Also, we estimate the sectoral price effect. The result of this analyses are presented: 0.7891 won in production-inducing effect, 0.3742 won in value added-inducing effect. When 1 won is produced by shipbuilding industry, 3.7808 persons in employ-inducing effect when 1 billion won is produced, and sectoral price effect is 0.0009% due to the 10% increase of price.
