  • Now days, firm's technology capability is recognized as important factor to forecast and to evaluate firm's business performance. There are many efforts to develop useful indicators by applying patent information that includes concrete description about technology. Many previous studies analyzed relationship between patent indicators and firm's performance. But they didn't consider time gap between a point of firm's invention activity and a point of firm's performance improvement. They didn't considered a character of industrial fields either. To overcome these limitations, we selected IT industry for target analysis industry. Time-series patent data and financial data from 41 American IT firms between 2000 and 2011 were used to analyze. In this study, We empirically analyzed subsequent effect of patent indicators on firm's business performance by using correlation analysis and regression analysis.

  • 이 연구의 목적은 창의적 체험활동의 하위 영역인 동아리활동에 대한 공업계 고등학교 교사들의 인식을 조사하여, 향후 공업계 고등학교의 특성에 맞는 창의적 체험활동을 할 수 있도록 바람직한 방향을 제시하는데 필요한 기초 자료를 제공하는 것이다. 이 연구의 응답자는 전국의 공업계 고등학교에 재직 중인 교사 393명이고, 동아리활동에 대한 5개 영역 32개 분야의 문항(중요도, 반영도)으로 구성된 설문지를 활용하였다. 연구의 결과는 다음과 같다. 첫째, 동아리활동 영역에서 중요도 분석 결과, '학술 활동'은 '발명', '문화 예술 활 동'은 '영상예술', '스포츠 활동'은 '도전활동', '실습 노작 활동'은 '학교 특성화 전공', '청소년 단체 활동'은 '스카우트연맹'과 '청소년적십자'가 가장 높게 나타났다. 둘째, 동아리활동의 영역에서 반영도 분석 결과 '학술 활동', '문화 예술 활동' 및 '스포츠 활동' 영역은 대체적으로 공업계 고등학교 교사들이 생각하는 중요도에 비슷하게 반영되고 있었다. 하지만 '학교 특성화 전공'을 제외한 '실습 노작 활동'과 '청소년 단체 활동'의 경우는 중요도와는 별개로 모든 분야가 잘 반영되지 않고 있는 것으로 나타났다. '실습 노작 활동'은 중요도 분석과 반영도 분석이 비슷하게 나타났지만 '청소년 단체 활동'은 중요도에 비해 반영도 값이 현저히 낮게 나타나 중요도와 반영도에 큰 차이가 있었다.

  • Although patents have mainly been considered as the results of the invention process, of late their value as strategic assets have increasingly been emphasized. Consequently, the competition for patents among firms has intensified, and the number of patent disputes have been steadily increasing. Patent disputes, which cause enormous expense and resource utilization, increase uncertainty and have been considered as a threat or problem for the firms involved. Patent disputes are expected to have a significant impact on the decision making about subsequent innovation activities. This study attempts to analyze the effect of patent disputes on the subsequent innovative activities of the firms that are sued. After experiencing litigation as defendants, we examine their subsequent patenting strategies. According to the results of the study, firms who are experiencing patent litigation are more likely to achieve high-quality patents and cite recent technology when they apply for patents. Meanwhile, patent litigation experience has been shown to negatively affect the amount of subsequent patents applied. This study increases understanding by examining whether patent disputes, which have been mainly recognized negatively as obstacles, can be an opportunity that comes during a crisis.

  • The paper proposes a knowledge innovation performance model by the dynamic data envelopment analysis with slacks-based measure approach for evaluating the effectiveness of 30 regional knowledge innovation activities in China from 2010 to 2016. In recent years, China has paid more attention to knowledge innovation activities, as central and local governments have pushed on with their innovation projects by lots of investment whatever the difficulties may be. Decision-maker is usually interested in judge its knowledge innovation performance relative to target benchmark by exploring whether one provincial administration region performs better among others and/or if the growth of economy will be benefited greatly by the knowledge innovation activities. To acquire the managerial insight about this issue from a comprehensively designed performance evaluation model, knowledge innovation activity is conceptualized as an intertemporal production process. Invention patent and regional gross product are imposed on desirable outputs, highlighting the need for knowledge economy. The empirical result shows that knowledge innovation has a positive effect on economic development. At the same time, decision-maker should be interest in the economic effect of patents' type and quality. The government should then encourage new technical applications with greater commercial value from a market-oriented perspective, in order to benefit the most from the innovation process in the short-run.
