Focused in the characteristic of R&D on Geoscience and Mineral Resources as basic research area, we survey on methods of public works' economic impact analysis including cost-benefit analysis and resent technology evaluation methods and suggest apply-methods to conduct economic impact analysis on R&D of geoscience and mineral resources. To conduct economic impact analysis on the basic research area, it need to identification research's out-come not just output. In this perspective, we propose a method, Input-Output-Outcome Roadmapping to identify the outcome of R&D and show the relation of input, output, and outcome of R&D. Furthermore, noticing the different effects of R&D from public works, we directly evaluate the use-value of the academic theory or geological maps through Contingent Valuation Method(CVM) and others developed as evaluation methods on environmental goods. In indirect application methods, it can evaluate the partial of the pubic works' benefit with assuming R&D factors if R&D is a part of public works. If not, we evaluate the R&D's value as reductions of costs or additions of benefit with finding related public works.

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.

This paper has two objectives. One is to understand status of the distribution industry in Korea and compare it with industrialized countries. The other is an attempt to apply input-output(I-O) analysis to investigate the economic impacts of the distribution industry in the national economy for the year 2008. In the economy as a whole, the distribution industry represented about around 15 per cent employment and accounted for near 8 percent in GDP. The employment portion of the distribution in overall industry is almost same that of US, UK, and Japan, but shared portion in GDP is at least 3 per cent below these countries. Next, a static I-O framework is employed, focusing on two topics in its application. First, the impacts of the product or investment in the distribution industry on the product, value-added, and employment of other sectors are explored by using demand-driven model. Second, the national economic impacts of the distribution industry in Korea are looked into by using open model and inter-industry analysis. It can be summarized that the distribution industry has a high production-inducing effect, more worker and employment-inducing effect, a high forward and a low backward linkage effect. Finally, the implications and limitations of this study are discussed.

In the glocalization a common phenomenon of several nations reveals knowledge innovation and growth by the important subject of region and state and is studied at theory and practice. the successful cases of regional development in an advanced country have leading innovation through regional innovation system and cluster. therefore we are necessary to analyse how the knowledge spillovers in innovative cluster as the reduced model of regional innovation system guide firm innovation and region growth. this article reviews theories and empirical studies of the knowledge spillovers in the regional innovation system and innovative cluster of innovative geography and proposes a new research issues for further explorations of the knowledge spillovers. Previous studies assist that knowledge spillovers exist in knowledge-based industries of specific local area and local innovation accomplishes through pure knowledge spillover. but limits of these studies include narrow region and technological area, few analytical variable and exclusion of rent knowledge spillover. therefore new research topics related with that exemplifies geographical dimension(concentration and decentralization), technological dimension(knowledge based industry), category of analytic variables(previous indicators, time, and social capital), conceptualization(appropriation means, markets for technology) etc.

Econometric forecast models based on past time-series data have been applied to a wide variety of applications due to their advantages in short-term point estimating. These models are particularly used in predicting the impact of governmental research and development (R&D) programs because program managers should assert their feasibility due to R&D program's huge amount of budget. The construction governmental R&D programs, however, separately make an investment by dividing total budget into five sub-business area. It make R&D program managers difficult to understand how R&D programs affect the whole system including economy because they are restricted with regard to many dependent and dynamic variables. In this regard, system dynamics (SD) model provides an analytic solution for complex, nonlinear, and dynamic systems such as the impacts of R&D programs by focusing on interactions among variables and understanding their structures. This research, therefore, developed SD model to capture the different impacts of five construction R&D sub-business by considering different characteristics of sub-business area. To overcome the SD's disadvantages in point estimating, this research also proposed the method for constructing quantitative forecasting model using qualitative data. Understanding the different characteristics of each construction R&D sub-business can support R&D program managers to demonstrate their feasibility of capital investment.

기술기반사회로의 진화가 빠르게 진행되면서 경제성장에 있어 기술혁신의 중요성이 깊이 인식되어왔다. 그러나 혁신과 관련한 의사결정이 시장에만 맡겨질 경우 종종 시장실패가 일어나기 때문에 다양한 기술 혁신지원정책을 통해 공공이 개입하고 있는 실정이다. 공공의 기술혁신 지원정책이 수립, 시행되는데 있어 가장 중요한 근거는 경제적, 기술적 파급효과이며, 이에 근거할 때 공공차원의 선택과 집중이라는 문제도 합리성을 갖게 된다. 파급효과를 분석하기 위해서는 산업간 기술연관관계분석이 필수적으로 선행되어야 하며, 이와 관련하여 다수의 국내외 연구가 진행되어 왔다. 본 연구에서는 HS코드를 이용하여 산업별로 주 생산물 관련 키워드를 직접 생성하고, 특허 및 실용신안 등 지적재산권에 활용된 키워드 및 분류정보와 일치시킴으로서 지적재산권의 산업간 공유여부를 파악하는 메카니즘을 제안하고자 한다. 제안된 메카니즘을 제조업 세세분류(five-digit level)에 적용함으로서 세세분류산업간 연관관계를 제시하였다. 분석의 결과로서 부품소재산업을 중심으로 살펴볼 때 부품소재산업군과 여타산업군이 기술적으로 분절되어 있음을 확인하였다. 이 결과는 부품소재산업에서의 혁신은 부품소재산업군내에서 (비체화) 기술적 파급효과(disembodied technological spillover)를, 그리고 부품소재산업에서부터 여타 산업으로 (체화) 경제적 파급효과(embodied economic spillover)를 유발한다는 점을 시사하고 있다.

This study aims to identify the impact of the logistics industry on the Korean national economy. To do this, we used a MRIO table provided by the Bank of Korea which includes inter and intra regional relationship of the production and consumption for 6 areas - the Seoul Metropolitan, Gangwon, Chungcheong, Jeonra, Gyeongbuk, Gyeongnam area, but an original MRIO table was recomposed of 29 sectors focused on logistics industry for the purpose of this study. we analyzed producing-inducing effects, supply-shortage effects and inter-industry linkage effects based on logistics industry by region and industry. As a result, the logistics industry has more supply-shortage effect rather than production-inducing effect and has a higher ripple effect on the automotive in Gyeongnam area and petrochemical industry in Jeonra area. In particular, the ripple effect of th Metropolitan logistic industry was far smaller than that of other areas, because the Seoul Metropolitan industry was identified as the primary and middle demand industry.
