Whereas a large variety of previous studies show mixed results regarding the relationship between public investment and economic outcome, several studies have been conducted on related issues in Korea. The present study deals with the effect of public investment in Korea on economic growth and productivity. Using administrative data, it exploits three different methodologies: the total factor productivity approach, production function approach, and stochastic frontier production function approach. The results of this study show that public investment has a statistically significant effect on economic growth. However, it contributes little to enhance productivity. It is explained that there exists inefficiency of production in the Korean economy. These findings indicate that public investment has played a central role in the direct input factor and not in indirect role in Korea. Thus, it is necessary for public investment policies to concentrate on enhancing the efficiency of the Korean economy.

This paper tries to measure the spill-over effect of the production and investment of telecommunication service industry (hereafter telecommunication industry), using the most recent data of 2003 input-output tables. The results are summarized as follows. First, the industries which have the biggest spill-over effect from the production of telecommunication industry is miscellaneous business service (including the sale commission of telecommunication service), other engineering services (including royalty), and business consumption. Second, the production of telecommunication industry induces more value-added, and less production, less import, and less employment than related industries such as radio and television equipment, communications and broadcasting equipment, and computer and peripheral equipment. Third, while the investment of telecommunication service amounts to 15% of its production, the effect of the investment on production, value-added, consumption, and employment reaches 70% of that of its production. The policy implication of this paper is that the telecommunication industry contributes to overall economy mainly through its investment.

Each method for economic evaluation has its own characteristics. Therefore adoption of each of them in evaluation production investment project results in many problems. Hence combination & modification of them are required to perform more accurate evaluation about investment project. This paper discuss evaluation method of investment projects expansion and replacement investment on each line or individual in the production. Generally investment evaluation method has add to a few method by Subsidiary means with use a especial method. And then in this paper, a Taguchi Techniques is presented, which may be effective to the facilities appraisal or improvement. We propose a decision model to incorporates the values assigned by a group of experts on different factors in production. Using this model, SN ratio of taguchi method for each of subjective factors as well as values of weights are used in this comprehensive method for reducing production rate in production management.

The purpose of this study is to analyze the spillover effect of R & D investment focusing on agriculture sector. Therefore, the Korean industry is divided into 18 industries and the data period including 1970 ~ 2014 is analyzed. In addition, the method is based on the analysis of the production function, the growth contribution of the production factor, and the spillover effect of other industries that affect the agricultural output. The results of this study are summarized as follows. First, R & D investment has a positive effect on the production of Korean agriculture. Second, the impact of high tech industry R & D investment on Korean agriculture is positive. Third, the R & D investment in the public sector is relatively higher than the R & D investment in the private sector. In the R & D stage, the R & D investment of the first level technology has a great influence on the production of agriculture. As a result of this study, governments should consider the above mentioned research results to determine resource priorities based on limited resources in relation to R & D investments that contribute to production and economic growth.

본 연구는 공연여건의 성장에 걸 맞는 투자시스템으로의 변화를 모색하는 데 있다. 특히, 제작사들이 원하는 장기공연이나 오픈런 방식으로 공연여건이 조성되고 있는 상황에서 연장공연 여부를 신속히 판단할 수 있고, 제작자와 투자자 양자가 만족할 수 있는 미국식 예산수립 방식으로의 변화모색이 필요한 시점이다. 이에 구체적으로 3가지 방안을 제시하였다. 첫째, 연장공연이나 재공연 여부를 보다 정확히 판단하기 위해서는 현재와 같이 평균비용(Average Cost)을 산출하여 평균수입과 비교하기보다는 미국과 같이 한계비용(Marginal Cost)을 산출해서 비교해야 할 것이다. 둘째, 수익배분에 대한 불합리성을 극복하기 위해서는 현재와 같이 총제작비를 투자모수로 삼기보다는 미국과 같이 총제작비에서 운영비용(Operating Cost)을 제외한 프로덕션비용(Production Cost)만을 투자모수로 삼아야한다. 셋째, 앞서 언급한 한계비용의 산출과 프로덕션비용의 산출을 위해서는 미국 지출예산(Expense Budget)의 이원화 작성법의 국내 적용이 필요하겠다.

The main purpose of this research is to analyze the changes in investment motivation by year through time series and cross-sectional analysis of the factors and investment decisions of Korean manufacturing companies. According to the investment pattern for Asean from the 1980s to the 19th, the first expansion period was 82 to 86, the average increase in overseas investment for securing foreign raw materials due to the second oil shock, and the second expansion period was a gradual increase in exports to the U.S. in 1987 to 1996. During the first stagnation period, direct investment in Asean stagnated in the aftermath of the 1998-05 Asian crisis, and in the third expansion period, part of the production facilities invested in China were relocated to Asean, increasing Asean's investment to become Korea's largest manufacturing investment in 17. Korea's proportion of investment in Asean surpassed that of mass investment since 10 years ago, and the proportion of investment in manufacturing sector has been transferred from China to Asean, and after 17 years, it has served as an overseas production base connecting China. As such, The main purpose of the research will be to extract the determinant factors and key factors for overseas direct investment and investment patterns in conjunction with global manufacturing companies' production base relocation and investment trends through empirical analysis. This research paper gave basic reference to the motivation and determinant of investment 16 years ago, and analyzed the changes in investment motivation by year and content through empirical analysis, contributing some reasonable purpose to the decision of companies and policy makers interested in overseas direct investment.

The business value of IT has been the focus of the academic and business field in recent years, along with the massive IT investment. Unfortunately, those studies have not been able to demonstrate strong linkages between the IT investment and performance. The impact of IT investment on performance is an important research topic that needs to consider the role of key contextual factors and intermediate factors. This study develops an integrated model for IT investment, with the mediating effects of production/coordination performance towards firm performance. In addition, the model is moderated by some factors like ISP(Information Systems Planning), Business Planning alignment, top management support, IT education and training, and process innovation. The empirical result, based on the moderating regression analysis, indicates that the relationship between IT Investment and production/coordination performance is significantly positive depending on moderating factors. However, production/coordination performance is partially related to firm performance.

This study is aimed to analyze investment effects of fisheries R&D projects of the National Fisheries Research and Development Institute(NFRDI). In the analysis, Granger causal relations between R&D investment and fisheries production are tested. In addition, time-lag effects of fisheries R&D investment are estimated with an impulse response analysis and investment effects of R&D projects are estimated by changes of social surplus. Results indicate that there exists an Granger-causality between R&D investment and fisheries production and fisheries production responds to the fisheries R&D shock about three years after the initial shock. The magnitudes of the impacts increase until a peak is reached 5~7 years and the impacts decline to zero after 25 years. As investment effects, it is shown that the internal rate of returns of fisheries R&D investment is 55.2%.

재고투자와 경기변동의 관계를 설명하는데 있어 생산평활(production smoothing) 가설과 재고소진 회피(stock-out avoidance) 가설은 서로 상반된 입장을 취하고 있다. 기업의 재고 투자에 관한 의사결정은 두 가지 동기 모두에 의해 영향받을 것으로 생각되지만 경기국면에 따라 각각의 영향력의 상대적 크기 혹은 방향성이 다르게 나타날 수 있다. 이에 본고는 재고투자 동학에서 생산평활 동기와 재고소진 회피동기의 상대적 유의성을 실증적으로 검증하되 경기국면별 비대칭성의 존재와 형태를 규명하는 데 분석의 초점을 둔 점에서 기존 연구와 차별성을 지닌다. 이를 위해 기존의 선형 재고투자 모형을 확장한 비선형 모형을 설정하였으며 이러한 방식이 기존 방식에 비해 우수한 지를 모형의 예측력을 비교 평가하여 확인하였다. 분석 결과, 재고투자 동학의 경기국면별 비대칭적 특성을 확인하였다. 경기 호황기에는 재고소진 회피동기가 나타나지만 생산평활 동기는 유의하지 않았다. 반대로 경기 불황기에는 재고소진 회피동기는 유의하지 않지만 Ramey (1991)에서 제시된 생산비용의 비볼록성에 의하여 재고변화가 경기침체를 심화시키는 경기 의존적 특성을 발견하였다. 경기국면별 비대칭성을 모형에 고려함으로써 그렇지 않은 모형에 비해 예측력을 향상시킬 수 있음을 표본 내 및 표본 외 예측, 다양한 예측력 검정을 통해 확인하였다. 본 연구의 결과는 재고투자의 동학과 경기 불안정화 특성에 대한 이해를 제고하여 경제전망 등에 활용될 수 있을 것으로 기대된다.
