There has been emerging general agreement on the relative importance of producer services in a economy. This research describes the spatial patterns and trends in producer services at different spatial scales. The other research aim is to explain the impacts of producer services on spatial changes at the national level and at the intra-metropolitan level in Seoul. Producer services have highly concentrated in metropolises, especially Seoul. Between 1986 to 2001, an important spatial change in the producer services at the national level has been their growth in the Capital Region, reinforcing the role and function of Seoul. This reinforced role of Seoul is closely related to its competitive advantages arising from economies of urban. There have been some dramatic changes in the location of producer services within Seoul. The most important change was the growth of the Youngdong area, previously a sub-center for businesses, as the most important location for producer services, exceeding the previous dominant role of the CBD area. The changing urban form of Seoul is partly related to the onset of some diseconomies of urbanization in the CBD, while at the same time Youngdong has reached a stage at which it is benefiting from the agglomeration of a variety of firms, in addition to a favourable social and physical infrastructure.

This paper is a case study on regional linkages of producer services in Chinju region. Producer service appeared as the most rapid growth sector in service industry. In Chinju region. manufacturing firms purchase generalized producer service within the region. However the higher-order service, they demand; the remoter metropolis especially Seoul, they depend on. Linkage patterns among manufacturing sectors are similar; but then the firms whose managers are from Chinju or Gyeong-nam region had stronger regional linkages than others. Public institute such as Chamber of Commerce & Industry, University Research Institute of Industrial Technology. Korea Technology Credit Guarantee Fund, Korea Silk Research Institute have made important role as suppliers of public producer services in Chinju Region. As present stage, their services of industrial technology, fiancing, and information are not only fit regional demand but also spatially limited within region. The facts that large firms purchase high-order services from other region and small firms have not good demand of producer service suggest regional policy implication about supplying relevant producer service in the region.

본 연구에서는 lot-for-lot 정책으로 운영되는 불균등한 bargaining power를 갖는 단일 생산자와 단일 수요가로 구성된 공급망 시스템에서 생산자와 수요가의 생산량(또는 주문량)의 결정을 위한 통합 모델과 이에 따르는 통합효과의 적정 배분방법을 제안하고자 한다. Quantity incentive라는 개념을 고안하여 공급망 시스템에서 우위를 점하고 있는 생산자(또는 수요가)에게 수요가(또는 생산자)가 현재의 운영정책의 변경을 요구하고 이에 상응하는 보상금을 지불하는 형태의 조정방법을 제안하고자 한다. 이러한 과정을 통해 안정적인 공급망 시스템 운영을 위한 통합 효과의 적정 배분 방법을 추가적으로 제시하고자 한다.

This paper examines the effect of bargaining power over intermediate goods prices on innovation and economic growth using a Schumpeterian growth model. The notion of "intermediate goods prices" broadly indicates the reward to innovators including innovative SMEs as well as intermediate goods producers that are vertically integrated to big businesses. From this viewpoint, this paper sets up a Schumpeterian growth model that incorporates the market power between final goods producers and intermediate goods producers. The results show that the reduction of intermediate goods prices slows down long-run growth rates as it erodes the reward to innovations. Lower intermediate goods prices decrease marginal productivity of capital and real interest rates. However, the harmful effect of lower profits on innovations outweighs the beneficial effect of lower interest rates. Simulations using Korea's data for various cases show that in all cases the policies that raise the share of intermediate goods producers are as powerful as the R&D subsidy policies in raising growth rates. Therefore, fair trade policies that enable intermediate goods producers-especially SMEs to obtain more fruits of innovations will be helpful for long-run economic growth.

생산자동화기술을 도입하여 도입성과를 향상시키려면 자동화기술을 도입하고 활용함에 있어서 성공요인들을 문헌과 현장의 사례들을 통하여 충실히 검토하고 종합적으로 분석한 후에 이를 생산시스템에 적용할 때에는 자동화기술의 상반관계(trade-off)에 있는 성과변수를 동시에 향상시켜 경쟁력을 갖게 될 것이다. 기업전략과 생산전략을 수립하고 그 틀 안에서, 생산자동화기술 추진전략을 세워 전략사이의 적합성이 높을 때 자동화기술 도입성과는 크게 향상될 것임을 유념해야 한다. 따라서 본 연구에서 제시한 생산자동화기술 성공요인이 자동화기술 도입성과에 영향을 미치므로 자동화기술 추진전략이 기업의 능력범위 안에서 이들 요인을 잘 반영하고 있는지를 검토하고, 분석한 후에 종합적으로 판단하여야 한다. 이러한 과정을 거쳐 자동화기술이 도입되고 운영될 때 자동화기술 도입효과는 극대화될 수 있다.

금년들어 서울의 육계값이 폭락하여 생산자는 생산원가에도 미달되는 값으로 출하하고 있으며 일부 양계 초심자나 영세업자는 생산물의 체화로 판매처가 없어 위탁판매, 외상판매 등으로 막대한 손해를 보고 있다는 여론이 있어 축산물의 유통을 담당하는 실무자로서 방관할 수 없어 대책을 연구하고자 생산자, 소비자, 중간상인, 거래장소, 도계장, 치킨센타 등을 찾아다니며 현황을 확인한 바 다음과 같은 사실을 파악하여 대책을 연구 미흡하나마 확인된 자료를 공개하는 바이다.

As the worldwide trade of agricultural products became liberalized with the establishment of WTO and FTA, relatively cheaper agricultural products have influenced the Korean domestic market substantially. Fortunately, foreign countries have soften their restrictions on Korean agricultural exports, providing Korean farmers with more opportunities to advance into the world market. This study aims to propose a multiple-criteria decision-making model for selecting an optimal tomato export farm, as the part of an effort to vitalize exports of domestic agricultural products amid the competitive agricultural market worldwide. For this purpose, we are suggesting a 2-step decision-making model which consists of a simple hierarchy decision model that preliminary selects tomato export farms and a detailed hierarchy decision model that chooses the final and optimal tomato export farm. We applied the analytic hierarchy process (AHP) to determine the relative importance of the used evaluation factors and to choose the tomato export farms with most potential. Eventually, the systematic and efficient decision-making model proposed in this paper can be applied to determine the optimal export farms for crops other than tomato, and thus it can encourage the competitiveness of Korean agricultural exports.

As the economy grows, there is a concern that the economic development causes a productivity reduction because of the service intensive growth. However, the economy of developed countries encounter with the productivity growth as their economy grows, which phenomenon called Baumol's paradox. Oulton (1999, 2001) find out the reason of Baumol's paradox in a forward and backward chain effects. So, this paper is aimed at verifying the theory of Oulton (1999, 2001). Moreover, we test the difference effect between a consumer service and producer service input using a dummy variable. We use the Input-Output Table (1990, 1995, 2000, 2005) that is offered by the Bank of Korea to accomplish the purpose of our research that is represented above. We find out that the Korea's intermediate producer service inputs cause a multifactor productivity growth. That result is matched with the Oulton (1999, 2001)'s theory. But, the intermediate consumer service inputs don't have a significant effect on a multifactor productivity. The result of verifying the effect of intermediate producer service inputs among industries shows that the effects on manufacture industries are less than other industries.

본 논문은 (1 : 1 : $N$) 재고모형에 대한 복수제품의 순환생산 및 배송 일정계획을 수립하는 연구를 수행하였다. 세부적으로 공급자가 원자재를 생산자에게 배송하면, 생산자는 순환생산방식을 활용하여 복수의 제품을 생산하여 $N$ 구매자에게 배송하는 상황을 고려하고 있다. 본 연구의 목적은 공급자, 생산자, 구매자를 포함하는 시스템 전체의 비용을 최소화하는 계획을 수립하는 것이다. 최적해가 가지는 몇 가지 특성들을 분석하고, 이를 통해서 단계적인 휴리스틱 절차를 제시할 것이다. 테스트 실험을 통해서 제시된 휴리스틱 절차가 매우 효과적이면서도 효율적이라는 점을 입증하게 될 것이다.
