현재 국내 원자력 발전산업은 상당한 기술자립을 이루었고, 외국으로의 기술 수출을 시도하고 있을 정도로 상당한 경쟁력을 갖고 있다는 의견이 지배적이다. 실제 한국전력, 원자력 연구소 등에서는 원자력 기술을 해외에 수출하고자 노력하고 있다. 원자력 발전기술의 해외 수출이나 연구개발 사업에서 가장 중요한 지표 중의 하나가 원자력 발전산업의 기술수준 또는 기술경쟁력이다. 또한 국외 뿐 아니라 국내에서도 발전원별 경쟁체재 도입으로 인해 원자력 발전의 경쟁력 평가는 원자력의 타 발전원 대비 경쟁력 확보 측면에서 중요한 사항이 되었다. 본 연구에서는 원자력 발전산업의 효율적인 기술개발 전략 수립을 지원하기 위한 모델을 System Dynamics 방법론을 사용하여 개발하였다. 이를 위하여 우선 원자력 발전산업의 기술경쟁력 평가를 위한 변수 및 평가범위를 선정하고, 선정된 변수들의 인과관계를 정성적으로 평가할수 있도록 인과지도(Casual Loop Diagram)를 개발하였으며, 이를 정량화하여 평가할 수 있도록 흐름도(Stock Flow Diagram)를 개발하였다. 개발된 모델을 사용하여 총 연구비 등의 정책관련 변수들을 변화시키면서 시뮬레이션을 수행해보았다. 본 연구의 한 결과로서 기준 시나리오에 대한 분석 결과 2004년 이후의 원자력발전산업 순편익 누적 결과는 다음과 같다. 순편익 누적(억원) : 2015(년도) 19,169, 2025(년도) 61,396, 2035(년도) 106,598, 2045(년도) 143,813, 발전 비용 감소분 누적(억원) : 2015(년도) 9,370, 2025(년도) 39,182, 2035(년도) 73,409, 2045(년도) 103,212, 국산화율 증가로 인한 수입액 감소분 누적(억원) : 2015(년도) 6,388, 2025(년도) 13,367, 2035(년도) 18,756, 2045(년도) 22,595, 시장점유율 증가로 인한 수출액 증가분 누적(억원) : 2015(년도) 3,411, 2025(년도) 8,847, 2035(년도) 14,433, 2045(년도) 18,005 또한 시나리오 비교평가를 실시하여 본 결과, 본 연구에서 정의한 순편익 누적(Cumulative Net Profit) 변수를 적용하면 현재 연구비 추세 대비 $30\%$ 까지 연구비를 증가 시키는 것이 효율적임을 알 수 있었다.

This paper examines a country's strategic optimal tariff policy against a foreign firm with market power. That is, the purpose of the paper is, under asymmetric information, to reexamine the problem of optimal tariff policy against a foreign monopolist from another country's welfare standpoint. This is to extend the analysis of Brander and Spencer(1984) which is both analytic and elaborate. The incentive compatible tariff schedule is derived, and then policy implications are investigated. The main result is that, under incomplete information, the optimal tariff is elevated above its full-information counterpart in order to capture foreign rents. Moreover, it suggests that trade policies motivated by rent extraction are unlikely to be robust to the introduction of incomplete information. This research complements an existing literature on the strategic trade policy in terms of asymmetric information.

In this study, we explore the characteristics of directors' network structure and investigate the relationship among the network of board directors in the Korean logistics industry. Social network analysis reveals hidden patterns of the interlocking directors' network. We construct a directors' network index using social network analysis of the Korean logistics industry. Empirical results have showed that of the 23 companies analyzed, the network index of Korean Air is the highest. The interlocking network index of Korean Air, Hanjin and Hanjin Logistics Company is 0.4, 0.32 and 0.24 respectively. Korean Air has a strong central interlocking network that can create social power through the logistics industry. Our paper contributes to the broad literature in two ways. First, unlike the existing literature on director structure, this paper concentrates on the relationship among interlocking directors. Second, logistics firms need to be aware of the importance of networks and recognize the occurrence of power.

Despite the same system architecture and operation principle, Advanced Metering Infrastructure (AMI) and Internet of Things (IoT) are recognized as a heterogeneous system. This is due to the different object modeling and communication protocols used in smart meters and sensors. However, data interworking between AMI and IoT is expected to be inevitable in the future. In this paper, we propose Device Language Message Specification (DLMS) to Lightweight Machine to Machine (LwM2M) conversion model. The proposed interworking model can reduce the packet size by 46.5% compared to that of the encapsulation method.

This study intended to exploratively depict the influence of interaction between Environmental Uncertainty and Learning Orientation of Korean IT companies on Marketing Capability which was adopted as one of the organizational performance indicator. Statistical Results based on AMOS and SPSS showed that smaller-sized companies under 500 employees are more inclined to desperately and flexibly meet and adapt to their environmental uncertainty, resulting positive performance, that is, marketing capabilities. On the other hand, larger-sized companies over 500 employees showed no significant interaction effect. This result of the study induces the reasoning that the differences in competitive environment and market leadership accrued by organizational size may also incur differences in environmental adaptive mechanism. However, this reasoning can have some limitation in that the types and traits of IT firms are so different. Therefore, this topic suggests the necessity of follow-up researches using enlarged samples in IT industry and comparative studies in other industries.

The purpose of this study is to identify key factors of Co-opetition through examining the environmental and structural changes in the ports industry and suggest a few Co-opetition strategies for enhancing our ports capabilities in the long-term. In recent years, the trend toward market liberalization and globalization in ports industry has made rapid progress and it made the competition fiercer. To survive in this rapid changes, the ports have traditionally pursed a competitive strategy. However, an alternative strategy replacing the traditional strategy was introduced: namely, 'Co-opetition' a buzzword combining competition and co operation. Policy proposals this study suggests are the construction of a database regarding costs and benefits of ports for more effective analysis and improving the competitive power of a shipping company operating national flag carriers for achieving the purpose of Co-opetition and adoption of selection and concentration strategy for increasing the possibility of Co-opetition success.

This study investigates the effects of real exchange rate (RER) on firm level mark-up and export. Using firm level data in Daegu-Gyeongbuk manufacturing industries during 2006-2013, we find that firms adjust their markup in response to the RER changes and this adjustment is heterogeneous with respect to firm and industry characteristics. In particular, an increase in markup following the RER depreciation is greater for firms with lower intermediate input import and higher industry concentration. However, productive firms in this region increase their export, instead of markup, during the RER depreciation. This implies that the productive firms in the region may not retain significant market power: They do not change the final price in local currency to increase selling volume during the RER depreciation (the export price in foreign currency decreases).

This study examines the current status of smart manufacturing innovation policies in Germany and Korea, compares and analyzes the supply industry strategies of both countries, and suggests the direction for Korea's smart manufacturing innovation supply industry. Germany's supply industry strategy aims to strengthen the market dominance of domestic suppliers through high technology, compatibility, and high reliability based on reference for global demanding companies. On the other hand, the Korea's supply industry strategy remains at the level improvement of the demanding companies by stage, so it is time to take a long-term and consistent response with the goal of implementing smartization at the advanced level. By referring to Germany's supply industry strategy for the advancement of smart factories, it was intended to help in establishing government support policies and supplier strategies. In addition, based on the analysis results of the supply industry strategies of both countries, improvement measures for the advancement of Korea's smart factories were presented. Ultimately, the contents of this study can be used as basic data for policy establishment to strengthen the industrial competitiveness of Korea's small and medium-sized suppliers.

The focus of our work is to identify and understand the drivers of alliance performance so that businesses can maximize their chances of a successful alliance-an area that has received little attention in empirical modeling. Although both conceptual and applied research on alliances has increased, an empirically tested comprehensive theoretical model that explains alliance performance has yet to be developed. Using five salient perspective, namely market power theory, transaction cost theory, the resource-based view, institutional theory, real option theory, this paper attempts to provide a theoretical rationale linking motives of global alliance networks on firm's capabilities, partner's capabilities, operating structures, and performances of Korean companies. The key contribution of this study is that it paints a picture of what matters in driving alliance performance. Our work shows the complex nature of driving performance and the interplay of firm's capabilities, partner's capabilities, and operating structures for understanding alliance performances. This study has given us a small but significant step forward towards understanding the intricacies of alliance performance. We are now better able to understand the respective roles played by various alliance factors and derive insights that lead to improved alliance performance.
