Many firms are trying to acquire innovative technologies and relative knowledge by offshoring R&D work. Although research to date has focused on the multinational corporations' motivations of R&D offshoring, such as cost reduction and market expansion, little is known about external or environmental factors influencing the performance of global R&D activities. We investigated the relationship between the offshore R&D performance and the technical capabilities of the parent company, the host country and the home country as enhancers from outside R&D facilities. The analysis uses European patent data and EU R&D scoreboard of 134 overseas R&D labs from 46 multinational corporations in 2005. Also, we calculated total patent number of each country for this. Results from path analysis supported our main hypothesis that the technological capabilities of the parent company and the host country positively affect the overseas R&D performances. By multi-group analysis, we also found that the relationships among the variables are different for each industry.

This study aims to examine the impact of corporate governance systems on the relationship between R&D investment and the performance of Chinese firms. The sample firms were obtained from the statistical yearbook of Chinese high-tech firms. We implement a multiple-regression analysis for an empirical examination. The findings of showed that the separation of the board chair with CEO strengthen the R&D investment-performance relationship of Chinese firms. However, the outsider ratio of the board was found to negatively moderate that relationship. This study provides practical guidelines for Chinese firms undertaking R&D management and corporate governance systems. It also encourages future study on the effects of corporate governance as the means for R&D investment management.

Military aircraft R&D projects require large-scale investment in cost and time, and involve a complex coordination process in decision-making. The R&D project manager should determine the development management priorities as accurately as possible and focus on R&D capabilities, thereby reducing the risks of the aircraft R&D project. To this end, this study aims to reduce R&D risk by prioritizing cost, schedule, and performance, which are basic management factors used in R&D project management in defense project management regulations. Analytic Hierarchy Process (AHP) is applied using a questionnaire for managers in charge of aviation R&D under the Defense Acquisition Program Administration. As a primary result, the importance of the factors that the aircraft R&D project manager should consider was derived in the order of performance, cost, and schedule, and the priorities of performance and cost in the lower layer were also identified. In addition, in order to provide practical risk management measures to aircraft R&D project managers, the results of analyzing 28 cases of US National Transportation Safety Board accidents were compared and analyzed with the AHP analysis results, and management measures suitable for the situation were specified.

This paper presents a new control scheme for a DVR (Dynamic Voltage Restorer) system consisting of series voltage source PWM converters. To control the negative sequence components of the source, it is necessary to detect the negative sequence components. Generally, a filtering process is used which has some undesirable effects. This paper suggests a new method for separating positive and negative sequences components. This control system is designed using differential controllers and digital filters. The positive and negative sequences are extracted and controlled individually. The performance of the presented controller and scheme are confirmed through simulation and actual experiment with a 2.5kVA prototype DVR system.

In Schumpeterian competition, superior profit arises from successful innovation created by firm's R&D strategy. Such R&D strategy diverges as time passes. This study examines empirically the effects of diverged forms of R&D strategy such as technological assets, technological diversity, and technological similarity on firm performance in Korean pharmaceutical industry. With the financial and patent data of 96 firms for 14 years from 1994 to 2007, we measured variables. And then we performed panel analysis with 3 years lag between dependent variable and other variables. The result shows that firm performance increases as technological asset and technological diversification increase. But technological similarity positively affects on firm performance in opposition to our hypothesis. We interpret and discuss these results and highlight the theoretical and practical implications of our findings.

This paper aims to explore the relationship between organizational competencies and performance by analysing perception survey data of R&D management agencies in Korea. The regression analysis results show the perceived performance measured by policy contribution and R&D management efficiency may be enhanced by organizational competencies such as professionalism and efficiency of R&D management specialized agencies. The paper suggests several improvement measures for strengthening professionalism of R&D management agencies in Korea. First, expertise competencies for strategic planning, management, evaluation need to be empowered in the whole process of R&D cycles. Second, in order to stabilize financial resources of R&D management specialized agencies, the existing R&D budget for Planing, Evaluation and Management should be reformed. Third, R&D management specialized agencies need setting up special organizations for managing inter-organizational collaboration with other R&D organizations. And the agencies should employ special experts in each position for strategic planning, management, evaluation, performance and commercialization. Finally, different R&D management procedures of each R&D management specialized agency need to be standardized in order to promote innovative R&D culture.
