The current environment of technological and competitive changes influences not only the business R&D environment but also government driven national R&D strategies. Open innovation has now become an important paradigm that is replacing the outdated paradigm of closed innovation. Many companies and nations have been increasing R&D investment because R&D has been considered a driving force for national and corporate competitive advantage. The purpose of this paper is to evaluate and compare the performance of R&D focused on open innovation according to scientific and technological outputs which is based on paper publications, patents and etc. Comparisons should not be only based on the quantity but also on the quality of the output. This paper shows that it is possible to develop DEA models that utilize the Analytical Hierarchical Process in order to transform the qualitative index into a quantitative index. Hence, the relative efficiency for R&D organizations is obtained based on both quantity and quality outputs and subsequently provides comprehensive and realistic methods for decision makers to identify levels of project efficiency.

The research purpose of this paper is to empirically examine the effects of technological readiness and innovation on logistics performance. To build up and maintain an important role in global supply chains, nowadays it is obvious that countries and logistics providers need to achieve competitive advantage in terms of digitalization. However, there is a lack of empirical studies about the impacts of information technologies and innovation potential on the logistics efficiency of countries. Hence, the study analyzes whether the corresponding pillars of the Global Competitiveness Index (GCI) matter for the Logistics Performance Index (LPI) and its dimensions. For determining the effects, the pooled regression approach is applied. The results show that technological readiness and innovation are positively and statistically significantly correlated with logistics performance: competence and quality of logistics services, efficiency of customs clearance processes, ability to track and trace consignments, frequency with which shipments reach consignee within scheduled or expected time, and ease of arranging competitively priced shipments. The findings of this study suggest that investments in innovations and technology progress improve countries' logistics efficiency, which is an important prerequisite for enabling Logistics 4.0 and thus, Industry 4.0 and the digital transformation of the economy and society.

흔히 우리의 취약한 기술력은 GNP에 대한 R&D 투자비중이 낮은 것으로 대변되고 있고, 기술개발투자의 확대가 기술력 향상과 동일시되고 있다. 그러나 산업발전단계(産業發展段階)에 따라 개발대상(開發對象) 기술(技術)의 구성(構成)이 달라지므로 선진국에 비해 R&D 비중이 낮다고 하여 반드시 기술개발 노력이 부진한 것은 아니다. 한국(韓國)은 기술개발에 투입할 경제여력이나 그것을 담당할 수 있는 고급 인력의 공급측면에서 선진국에 비해 절대적 열세에 처해 있는만큼, 연구개발투자(硏究開發投資)의 절대 수준도 중요하나 기술개발(技術開發)의 성과(成果)를 극대화하기 위한 기술의 획득(獲得) 및 습득과정(習得過程)의 효율화(效率化)에 최선을 다해야 할 것이다. 산업경쟁력(産業競爭力) 향상을 위한 기술개발정책(技術開發政策)의 기본방향(基本方向)은 국내산업의 기술발전단계와 연구개발의 국내기반에 입각하여 기술개발투자(技術開發投資)의 효율화(效率化)를 위한 국제화(國際化) 전략(戰略)의 전개, 기업중심의 연구개발(硏究開發) 네트워크의 고도화, 공공연구기관의 정예화(精銳化) 및 대학의 연구활성화(硏究活性化)를 유도해 나가는 것으로 요약된다.

This paper analyzes economic efficiency of strawberries and tomatoes farms using the data envelopment analysis (DEA). We examine how production characteristics and farm size affect overall efficiency (OE), allocative efficiency (AE), and technological efficiency (TE). We also survey sample farm households from the Farm Income Investigation database of Rural Development Administration to investigate management and cultivation techniques and to analyze economic efficiency by technique. Implications for improving efficiency are suggested in the conclusion.

Knowledge-based exporting companies in Korea have reached a stage to develop new technological innovation and to pioneer new markets. But, developing new technologies and launching new products require an enormous sum of money for Research and Development(R&D) and there is still uncertainty in technological development and markets. Therefore, through open technological innovation, they are encouraged to actively use external technological sources and ideas. They also need to enhance the efficiency of the relatively little R&D investment. In this paper, firstly, it conducts a precedent study on the concept and influence factors of knowledge-based exporting companies and open technological innovation. Secondly, it sets a study model and estimates a regression coefficient to analyze the influence factors of open technological innovation of knowledge-based exporting companies which are using external resources on the process of innovation. Through case study and empirical analysis, we are going to find the implication of open technological innovation and prepare the way of the innovation for the knowledge-based exporting companies. According to the empirical analysis, variables such as firm size, processing degree, product life, patent registration, maintaining internal security didn't have positive effects on open innovation performance. On the other hand, research capability and market preoccupancy had positive effects. Therefore, to succeed in open innovation, knowledge-based exporting companies not only need to secure research capability through open innovation, but also need to preoccupy the market through commercialization of developed product.

The purpose of this study is to measure the productivity of fisheries in China's coastal areas (including inland and marine fisheries) and to analyze the factors influencing the development of fishery economy in each province by comparing regional differences. The input indicators used for efficiency analysis are fish farms, ships and staff numbers, and the output indicators are fish catch and net income. In this paper, we used six years of data from 2013-2018 and DEA-Malmquist index was used to analyze the efficiency of coastal fisheries production in 11 areas of China's coast. According to the analysis from 2013 to 2018, the fishery output efficiency in China's coastal areas has improved to some extent, but most provinces and regions are characterized by technological progress, and the technological efficiency still needs to be further improved. The conclusion can provide reference for the development planning and policy measures of regional fishery industry in China's coastal areas.

정부는 기술혁신을 통한 경제성장을 견인하기 위하여 R&D 투자를 지속적으로 증가시키고 있다. 따라서, 정부 연구개발 집약도는 매우 큰 폭으로 증가되고 있으나 절대규모에 있어서는 선진국에 비해 여전히 적은 재원을 보유하고 있다. 또한, 연구개발 정책방향이 기술추격형에서 기술선도형으로 전환되고 있어, 공공 R&D 재원의 효율적 활용에 대한 관심도 매우 증가하고 있다. 이에, R&D 효율성을 측정하고 효율성에 영향을 미치는 요인을 분석하기 위한 다각적인 시도가 행해지고 있다. 본 연구에서는 NTIS(국가과학기술지식정보서비스)의 과학기술 투자 및 성과 데이타를 활용, 자료포락분석(DEA)을 이용하여 논문, 특허 등 과학기술적 성과관점에서 정부 순수R&D사업의 효율성을 측정하였다. 더 나아가서, 효율성에 영향을 미치는 배분특성을 규명해 보고자 통계적 유의성 확보가 어려운 데이터 문제들을 보완할 수 있는 비모수 분석 방법인 Mann-Whitney 검정을 활용하였다.

This study compares domestic and foreign research on renewable energy-based water electrolysis clean hydrogen. Domestic studies from 2010 to 2023 focused on technological efficiency, energy efficiency, and system efficiency, with few analyzing infrastructure and technology trends. Overseas research initially focused on technological efficiency and stability, but has since shifted to economic and environmental impact, policy effectiveness, industry-university-research cooperation, and sustainability. To improve water electrolysis technology production, this study suggests prioritizing technology stability over efficiency, resolving government regulations and resident acceptance issues, promoting industry-university-institute cooperation for rapid commercialization of research results, and developing a strategy for sustainable development of renewable energy-based water electrolysis technology.

To ensure reliable and secure communication in heterogeneous cellular network (HCN) with imperfect channel state information (CSI), we proposed a coordinated multipoint (CoMP) transmission scheme based on dual-threshold optimization, in which only base stations (BSs) with good channel conditions are selected for transmission. First, we present a candidate BSs formation policy to increase access efficiency, which provides a candidate region of serving BSs. Then, we design a CoMP networking strategy to select serving BSs from the set of candidate BSs, which degrades the influence of channel estimation errors and guarantees qualities of communication links. Finally, we analyze the performance of the proposed scheme, and present a dual-threshold optimization model to further support the performance. Numerical results are presented to verify our theoretical analysis, which draw a conclusion that the CoMP transmission scheme can ensure reliable and secure communication in dense HCNs with imperfect CSI.
