This study aims to analyze how much KF-X production impacts on national economy by measuring economic spread effect based on inter-industry analysis. In order to evaluate the economic impact of KF-X production, we used input-output table of year 2007 of Korea. The results shows that KF-X production induces the production of 3,129 billon won and the value added of 1,206 billon won respectively. Also there are the creation of about 13,208 employment in the industry. The results from this study can be used as a basis for the further research on whether or not KF-X production could be processed.

Korea is one of the countries that propel new renewable energy industrialization actively in the context of change in this industrial structure. The previous government declared this kind of industrialization as a national goal in 2004 and the current government also supports this strategy. However, it is necessary to check whether this strategy is proper and effective. The reason is because solar, wind and fuel cells that have attracted public attention as the new growth engines cannot replace main industries yet. This paper tries to analyze the economic effects of new renewable energy industrialization by dividing them into production effect and job creation effect. The result of this analysis shows that solar energy is not effective at all, while wind energy is very effective in both production and job creation. In conclusion, this paper suggests that the government has to propel new renewable energy industrialization after consideration of these kinds of economic effects.

본고에서는 ICT서비스가 사회경제적으로 미치는 파급효과를 분석하기 위하여 ICT서비스를 IT제조업, 통신 및 방송 서비스업, 컴퓨터관련 서비스업으로 재분류하고 2005년의 산업연관표를 이용하여 파급효과를 분석하였다. 그 결과 생산유발계수에서는 민간소비와 정부소비지출에 있어서 기간통신서비스가 가장 높은 효과를 보였으며, IT산업이 제조업분야 보다 서비스 분야에서 높은 부가가치를 창출하고 있는 것을 알 수 있었다. 또한 부가가치 유발효과는 민간 및 정부 소비지출 측면에서 통신 및 방송서비스, S/W 및 컴퓨터관련 서비스 부문이 높게 나타났다. 수입유발효과는 정보통신기기 부품 등의 수입유발이 컸으며, 서비스관련 사업은 수입유발이 낮게 나타났다. 취업유발과 관련되는 노동유발효과는 제조업이 가장 높게 나타났으며, 서비스업 측면에서는 S/W 및 컴퓨터 관련 서비스업에서 소비나 투자수요와 관련하여 높은 취업유발효과들 가지는 것으로 나타났다. 즉, 생산유발과 고용유발 측면에서 IT제조업 분야의 투자가 필요할 것으로 판단된다.

Dense of population construction and high density of skyscraper, and geological characteristics caused natural disasters(e.g. typhoon, tsunami, flood, storm, earthquake, etc.) and manmade disasters(e.g. fire, collapse, explosion, traffic accident, etc.). the extent and scale of the disaster are getting larger. To cope with such problems, Busan City has established the basic plan to secure the life and property of the citizens through model strategy and design of Ubiquitous-Safety Busan. This study quantitatively analyzed the ripple effect on local economy through the fulfillment of Ubiquitous-Safety. The production inducing effect of 250 billion won directly and indirectly can be estimated due to the realization of Ubiquitous-Safety. The value added effect of 115 billion won can be estimated. the employment effect of 5,580 persons can be generated with income effect of 51 billion won.

This study sets the boundary of U-City industry based on expert surveys. Based on this U-City industry boundary, an appropriate inter-industry analysis is performed. The result shows production inducement coefficients, value added inducement coefficients, employment & enter employment inducement coefficients, influence coefficients and induction coefficients. Based on these coefficients, overall characteristics and spillover effects of U-City industry are examined. The result of this study shows that U-City industry has bigger value added-induced effects and employee-induced effects than other industry. The result also shows that U-City industry also has a great forward linkage effect. This study has a meaning that could be used to make political decisions as a basic data.

This paper computes the economic impact of handset subsidies using the recent Input-Output Tables and compares the results with other alternatives which telecommunications companies can choose. The first scenario is that telecommunications companies give handset subsidies to consumers and sales agents. The second is that the companies do not give the subsidies to them, but instead spend the same amount of subsidy on facility investment. The third is that the companies lower the prices of their mobile communications services and consumers spend the saved expenses on other goods and services. The result is that the production, value added, import, job, employment inducement coefficients of the first scenario is larger than those of the second and third scenarios. The reason is as follows. The handset subsidy results in the incentive to consumers for handset purchase or the incentive for sales agents to sell the telecommunication services of the companies. The former has larger production and import inducement effect, and the latter also has larger value-added, job, and employment inducement effect than those of other scenarios.

본 연구에서는 고부가가치를 창출할 수 있는 문화산업이 제주 지역 경제에 미치는 영향에 대한 파급효과를 보기 위하여 산업연관분석 기법 및 AHP 기법을 이용하여 분석하였다. 그리고 제주문화산업에 대한 현황 및 문제점을 분석하여 Porter의 가치사슬 (value chain) 모형을 토대로 지역발전전략으로서 지식기반 제주문화산업의 육성방안을 제시하였다. 분석결과, 문화산업에 대한 투자가 지역경제에 소득유발효과, 고용창출효과 및 타 산업으로의 전?후방 연계효과 등이 강한 긍정적인 영향을 미치는 것으로 나타났으며 소득유발효과와 고용창출효과 등의 파급효과로 인한 제주지역 경제를 활성화시키기 위하여 기식기반 문화산업을 육성하여야 할 것이다.

This study examines the economic ripple effect on the domestic information security manufacturing and service sectors through input-output analysis. The production inducement coefficient of the manufacturing sector is bigger than the average of whole industry, but that of the service sector is smaller than the average. On the other hand, the service sector is superior to the manufacturing sector in the value added and employment inducement coefficients. Forward and backward linkage effects of manufacturing and service sectors are generally lower than those of the average of whole industry. The information security industry has insignificant contribution to national economy and employment growth overall. In particular, the manufacturing sector records minus contribution to employment growth, which means that a lot of effort for increasing employment must be given further on in the sector.

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.

Space exploration project usually consists of so many fields of sub projects that it has a diverse ripple effect throughout the economy. Further studies could not consider the complexity of the space exploration project because they regarded it as one project in spite of the diversity. This study found a way to consider complexity of space exploration project using the concept of WAC(weighted average coefficient). The moon exploration project (2014~2020) is the subject of this study. We classified the moon exploration project into 8 industries and calculated the WAC of production inducement coefficient, value added inducement coefficient, and employment inducement coefficient. The result of analysis using these WACs is that production inducement effect amounts to 1,229.6 billion won, value added inducement effect 324.6 billion won, employment inducement effect 4,844 men. And the linkage effect analysis shows that moon exploration project has more backward linkage effect than forward linkage effect.
