미국, 유럽, 중국, 일본 등 주요 선진국은 탄소 경제에서 수소 경제로의 전환을 위해 다양한 수소 경제 정책을 발표하며 연구역량을 집중하고 있다. 우리나라도 이러한 추세에 발맞추어 2019년 초 수소 경제 활성화 로드맵을 발표한 이래로 수소 경제 관련 법안을 마련하고 지원책을 실시하고 있다. 본 연구에서는 국가과학기술지식정보서비스(NTIS)의 국가R&D과제정보 최근 10년치 데이터를 활용해 수소 경제, 그중에서도 전·후방 파급효과가 크다고 할 수 있는 연료전지전기차 관련 R&D 현황과 지식구조를 파악하고자 한다. 연료전지전기차 관련 국가R&D과제(2020년 1월 기준) 1,479개의 원시 데이터를 바탕으로 네트워크 분석 및 텍스트 마이닝을 실시한 결과, 연료전지전기차 분야에서는 수소의 생산, 운반, 저장, 활용의 전 프로세스에 걸친 기술 및 시스템의 연구개발이 활발하게 이루어지고 있는 것으로 나타났다. 본 논문은 해당 연구결과를 통해 현재 연료전지전기차 산업을 선도하고 있는 한국의 수소 경제 관련 정책 수립과 연구개발, 시장 전략에 대해 시사점을 제시한다.

This study applied network agenda-setting theory to analyze the impact of the agenda-setting function of the media on certain issues by focusing on the agenda at the center of controversy, 'Creative Economy'. To this end, the study extracted the data referred to creative economy in the media and SNS from 1 January 2008 to 31 December 2014, and analyzed the data using the network analysis program UCINET and the Korean language analysis program Textom. The results of the present study show that, during the period under former President Lee (2008-2011), the media's creative economy agenda-setting function did not exert a significant impact on the agenda-setting within SNS. However, from 2012 when the government of former President Park Geun-hye had started, the agenda-setting function of the media starts to show increasingly strong influence on the agenda cognition in SNS. The central words and sub-words configuration forming the center of the semantic network moved in the direction of a high correlation, in addition to the gradually increasing correlation based on QAP correlation analysis. In 2014, the semantic networks of the media and SNS bore a close resemblance to each other, while the shape of networks and sub-words structure also had a high level of similarity.

We have done the input-output analysis to see the over all impact of flounder industry of Jeju region on the domestic economy of Korea. To do the input-output analysis, we have constructed the data set for the input-output table by using the existing data set in the "2003 input- output table of Jeju regional area" published by the joint work of Jeju branch of Korea bank and the Jeju Development Institute, together with some raw data provided by Jejudo Marine Fish-Culture Cooperative. We have also produced input coefficient of flounder industry by making flounder industrial sector exogenous, separated from intermediate demand. To summarize our empirical results, the inducement effect of production, value added, and employment of Jeju flounder aquaculture industry are 300 billion won, 116 billion won and 1,800 people respectively. In conclusion, the results of this study suggest flounder industry of Jeju region contributes powerfully to not only Jeju economy but also all over the Korea economy.

High oil price and global warming problem are being continued all over the world. For this reason, fuel economy and emission of greenhouse gas are regulated by law in many countries. Therefore many companies are researching and producing hybrid electric vehicles (HEVs) which substitute conventional internal combustion engine vehicle. However, these researches and productions are restricted to mainly passenger cars. Because of cost and physical problems, commercial vehicles are difficult to evaluate fuel economy. So simulations are important and it is necessary to know how sensitive parameters that enter into simulation affect. In this paper, forward simulations using AVL Cruise were conducted for analysis of fuel economy for parallel hybrid bus and were repeated by changing each parameter. Based on these results, root mean square errors (RMSE) are calculated for analysis of fuel economy sensitivity. The number of target parameters are 15. These parameters were classified with high and low sensitivity parameter relatively.

This article aims to explore the contribution of social media value to a company's financial performance in a digital environment economy since the awareness of companies and investors in the use of social media opens up new mechanisms for disseminating information. Quantitative method is used in this study with Multivariate Analysis of Variance as the analysis tool. The data used is secondary data gathered from Indonesia Stock Exchange (IDX) using 308 companies as samples. In the multivariate test, four kinds of multivariate significance tests were carried out, namely Pillai Trace, Wilk Lambda, Hotelling's Trace, and Roy's Largest Root. It was found that social media value has a small contribution in the difference of the level of profitability and the value of the company in Indonesia, but it doesn't have a contribution to the difference of the level of liquidity. The contribution was an implication of online Word of Mouth (WOM) motives which are interrelated with signal theory and as additional information for investors in relation to single-person decision theory. This study provides an insight into the importance of social media management considering that the world of digital economy will continue to develop, so companies in Indonesia need to take advantage of these opportunities.

우리나라 중소기업 CEO의 연령은 평균 58.8세로 기업승계 지원과 관련된 논의가 활발하게 진행되고 있다. 본 연구는 기업승계가 국가경제 및 지역경제활성화 정도에 미치는 영향을 살펴보았다. 자료의 신뢰성 확보를 위해 중소기업 통계 DB가 가장 많이 구축되어있는 중소기업지원사업통합관리시스템과 한국기업데이터 DB를 활용하였는데, 이 부분이 기존 연구와의 가장 차별화된 부분이다. 업력별 경영성과를 보면, 장수기업이 신생기업보다 매출액은 2배 이상, 종업원 수는 3배, 자산은 2배, 영업이익은 2배 이상의 높은 성과를 보여주고 있어 국가경제 전반에 미치는 기여도가 상당함을 알 수 있다. 2008년부터 2020년까지 중소기업을 대상으로 SAS의 Stepwise 옵션을 활용하여 매출액과 종업원 수, 영업이익 등 변수 간 회귀분석을 통해 분석한 결과 비수도권이 수도권보다 종업원 수, 자산, 차입금, 임차료 등에서 좋은 성과를 보여주고 있다. 이는 장수기업이 지역경제활성화에 크게 기여있다는 정책적 함의도 나타나 장수기업의 기업승계 지원정책 마련이 필요하다.

China has become the second largest economy since 2010. China's economy is supported by the rapid growth of its automobile industry. The rapid growth of the automobile and tire industry will increase the natural rubber (NR) demand as its primary raw materials. Although as a significant producer, China cannot fulfill the consumption by its domestic production. Thus China relies heavily on import from Southeast Asia countries as the primary producers of natural rubber in the world. China and Southeast Asia are dependent on their economy in terms of the availability of natural rubber as raw materials. But the economic slowdown in China since 2008 is expected to affect the international trading between China and Southeast Asia countries. This research aims to analyze the determinants of NR export from Southeast Asia to China using panel data analysis. The results show NR price, exchange rate, and China's economic slowdown significantly affect NR export to China, while Southeast Asian NR production has no significant effect. China as the main importer of NR from Southeast Asia has a big role in growing NR export in Southeast Asia. If China's economy doesn't improve soon, it will affect the economy in Southeast Asia.
