In den vergangenen Jahren ist im deutschsprachigen Raum eine Reihe von Studien entstanden, die sich mit wirtschaftlichen Auswirkungen von Hochschulen beschaeftigen, wobei vor allem die nachfrageorientierten regionaloekonomischen Ausgabeeffekte im Mittelpunkt stehen. Zu diesen Nachfrageeffekten gehoeren Auswirkungen der hochschulbedingten Ausgaben auf den Umsatz, die Beschaeftigung und das Einkommen. Sie lassen sich jeweils in direkte und indirekte Effekte aufgliedern und entstehen in der so genannten Phase der Leistungserstellung der Hochschule. Ziel dieser Arbeit ist es, angelehnt an bisherige Studien die regionalwirtschaftlich bedeutsamen Effekte der ausgewaehlten deutschen Hochschulen zu identifizieren und nachzuweisen. In der vorliegenden Untersuchung konnte festgestellt werden, dass die deutsche Hochschule einen wirtschaftlichen Stabilitaetsfaktor fuer die Region darstellt und traegt durch die Erhoehung des regionalen Einkommens und der Beschaeftigungseffekte erheblich zum Wohlstand in der Hochschulregion bei.

본 연구의 목적은 기존의 미디어 패러다임을 급격히 변화시키고 있는 IPTV 서비스를 대상으로 도입 3년 시점에서의 경제적 성과를 분석하는 한편, 향후 3년간 IPTV 서비스 도입에 따른 경제적 파급효과와 비교 분석하는 것이다. 비교대상이 되는 경제적 성과는 생산유발효과, 소득유발효과, 고용 유발효과를 포함한다. 우리는 이 분석을 통하여 IPTV 서비스가 과거 3년동안 어떤 산업에 어느 정도의 영향을 미쳤으며, 향후 어떤 산업에 큰 영향을 미칠지 전망할 수 있다.

This paper examines the estimate the economic impact of 2008 Andong Maskdance Festival, using an Input-Output(I-O) model. For the research, the Regional Input-Output analysis was used, which makes it easy to grasp the economic impact of the tourism industry and other industries in Andong. Based on the regional I-O transactions tables which were developed by Bank of Korea(2009), the industry multipliers were derived with respect to output, income, and value-added. The results show that in 2008 Andong Maskdance Festival receipts generated output impact of 30,961 million won and 15,800 million won of income impact, 14,310 million won of value-added impact, respectively. I think the result of this study can be used as an objective indicator to help to establish and implement regional festival policies for the local government.

This paper analyzes both the FTA effects and FTA spillover effects on bilateral trade using 62 countries' panel data during the period of 2003 ~ 2013. To this end, we construct a FTA dummy variable for the effect of FTA in the model and the weighted FTA matrix interacted with export and import for the spillover effect of FTA. Gravity model is applied to the empirical analysis with GMM, fixed and random effects, and PPML estimation. As a result of the analysis, FTA variables have positive relationships with bilateral export and import. The weighted FTA matrix interacted with export and import also have positive signs on the bilateral export and import in all estimations. Thus, we conclude that various FTAs of neighbor or 3rd countries increase the bilateral export and import. We provide some implications that a country to increase the amount of trade has a trade relationship with the countries having various FTAs and for the FTA effect analysis, the three-country model is better than to the two-country model.

This purpose of this paper is to study the economic effects of port-liquid freight by focusing on Korea port and induce its policy implication. For this, 29 sectors' input-output tables with port-logistic sector as an individual sector is constructed. The direct industrial effects of port-liquid freight are analysed to be an increase in about 3.6billion dollars' worth of production of the port-logistic industry, an increase in about 1.98billion dollars' worth of value-added of the industry, and the creation of about 11,589 employment in the industry. Including the indirect effects, the total effects on Korea economy are estimated to be an increase in about 4.9 billion dollar's worth of production, an increase in about 2.4 billion dollars' worth of value-added and an increase in about 17,746 employment. The total effects of port-liquid freight on Korea economy is about 2.5-3.0% of that of port-logistic total freight. the results suggest tkat thought economic effects of port-liquid freightare not large, we have to focus on policy support for port of port-liquid freight.

This study evaluated its potentials by quantitatively analyzing the national economic impact of the smart home-related industry, which is attracting attention as a core industry of the 4th industrial revolution. For the analysis, the smart home-related industries were classified into manufacturing and service industries through a literature review of the previous studies. Using the 2018 input-output table, this paper analyzed linkage effects between industries as well as spillover effects in the production, value-added, employment and job. As a result, the smart home manufacturing and service sectors showed a higher spillover effect in value-added than other industries in each industrial field. In the smart home industry, the spillover effects of manufacturing sector to service sector are larger than those of service sector to manufacturing sector. Moreover, it was confirmed that smart home industry was highly related to not only the technology-intensive industry, but also the service sector for smart cities, smart cars, Fin-tech, and etc. On the other hand, the smart home manufacturing sector is a final demanding industry with relatively higher backward linkage effect than forward linkage effect. In the smart home service sector, the forward linkage effect was relatively high compared with the backward linkage effect, indicating that it was an industry with a high supply function to other industries.

Analyzing information diffusion in a blog world is a very useful research issue, which can be used for predicting information diffusion, abnormally detection, marketing, and revitalizing the blog world. Existing studies on information diffusion in blog networks establish explicit relationship between blogs, and analyze only the word-of-mouth effect through such explicit relationships. However, we observed that more than 85% of all information diffusion in a blog world occurs through non-explicit relationships. In this paper, we propose a new model that considers both explicit and non-explicit relationships between blogs in order to explain all information diffusion phenomena in a blog world. We verify the superiority of our proposed models through extensive experiments of information diffusions at a real blog net-work.

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.
