        김정홍 ( Kim Jeong Hong ) 한국경제학회 2003 經濟學硏究 Vol.51 No.2

        In is my objective to study the following three topics. First, I would like to observe the correlation between regional innovative capabilities and regional industrial performances in Korea. Second, relationships between innovation and industrial performance will be examined. Finally, I would like to analyse the possibilities of a feedback system between regional innovative capabilities and regional industrial performances. The results of this analysis are as follows. First, the correlation between regional innovative capabilities and regional industrial performances in Korea is relatively high. Second, research institutes and researchers are more important factors with respect to patents than R&D funds. Lastly, the empirical analysis has also revealed that innovative capabilities promotes industrial performances, which again reinforces other new innovative capabilities.

        R&D 혁신역량과 기업성과 간의 관계 : 대구지역 전략산업과 비전략산업 간 비교분석

        신진교,조정일 대한경영정보학회 2011 경영과 정보연구 Vol.30 No.2

        본 연구의 목적은 R&D 혁신역량의 구성요소가 기업성과에 미치는 영향을 분석 하고자 하는데 있다. 그리고 지역산업에 있어서 전략산업의 비중을 감안하여 전략 산업과 비전략산업 간에 비교분석을 하고자 하였다. 주요 분석결과를 요약하면 다 음과 같다. 첫째, 전략산업과 비전략산업 간의 차이분석 결과를 보면 CEO 기술혁 신의지를 제외한 모든 R&D 혁신역량 부문에 있어서 전략산업이 유의적으로 높게 나타났다. 기업성과에 있어서는 비유의적이지만 전략산업의 기업성과가 높게 나타 났다. 둘째, 전략산업 간 차이분석을 한 결과를 보면 기업성과에 있어서 유의적인 차이를 보였다. 총자산순이익률의 경우 메카트로닉스와 전자정보기기산업이 가장 높게 나타났고, 매출액성장률에서는 전자정보기기산업이 가장 높았다. R&D투입에 있어서 연구개발투자인력은 전자정보기기산업이 그리고 석․박사연구인력은 생물 산업이 가장 높았고 모두 1% 유의수준에서 전략산업 간에 유의적인 차이를 보였 다. R&D과정에 있어서는 기술혁신전략을 제외한 나머지 부분에서 전략산업 간 유 의적인 차이가 있는 것으로 나타났고, 대부분에서 전기정보기기산업이 가장 높게 나타났다. R&D산출인 지적재산권 보유 정도에 있어서도 전자정보기기산업이 6.75 건으로 가장 높았다. 셋째, 모든 산업에 있어서 R&D 혁신역량이 기업성과에 동일 하게 영향을 미치지는 않고 있다는 점이다. 그리고 일반적으로 R&D투입이 기업성 과에 양(+)의 영향을 미친다는 것과는 달리 석․박사연구인력과 같이 연구개발인력 의 질이 더 유의적으로 영향을 미치는 것으로 나타났다. 부분적이지만 R&D성과 보다는 R&D과정이 더 기업성과에 영향을 미칠 수 있는 R&D 혁신역량이라는 점 을 함께 발견할 수 있었다. We examined the relationship between innovation capability of R&D and the firm's performance by mainly comparing regional strategy industry with non-regional strategy industry. Also, this analysis involved comparing the relationship by regional strategy industry. For the purpose of this study, we divided innovation capability of R&D into input, process and output. The first of main results in this study was that regional strategic industry was significantly higher than non-regional strategy industry in innovation capability of R&D with the exception of the CEO's mind for technological innovations. However, we found no significant difference in the firm's performance. Second, in the results of comparing innovation capability of R&D and the firm's performance by regional strategy industry, electronic-information equipment industry was significantly superior to other industries. Third, it was found that the relationship between innovation capability of R&D and the firm's performance was different by regional strategy industry. Also, R&D manpower and R&D process were more significant factors affecting the firm's performance rather than R&D input and output.

        정부기관의 R&D 지원 기업의 생산성과 성장성 분석: 바이오·의료 산업을 중심으로

        황의종 ( Eui-jong Hwang ),황승준 ( Seung-june Hwang ),박근완 ( Geun-wan Park ) 한국생산성학회 2017 生産性論集 Vol.31 No.3

        This study is expected governmental R&D investments in situations where there is a problem of efficiency in government R&D investment and investment performance continued being raised is evaluated as to whether you can have an impact on corporate performance. So, This study classified 40 Industries, which are divided into the leading growth industry and the main industry, focusing on the second stage of the Leading Industry Development Project for Economic Region, to the similar industry between the representative flagship and the growth leader based on KSIC. Through this, Government R&D budget affects the management performance by industry and company size, and the business performance when it is invested in Regional companies. Based on the results of this study, we propose a policy direction for efficient investment of R&D. In order to analyze the performance of government R&D investment, the Bio·Medical industry (regional project) was selected from among the leading industry development project. For the analysis, we selected biotechnology and medical industry (local business) among the Leading Industry Development Project for Economic Region that were promoted for three years from 2012. Analysis indicators we analyzed the enterprise (large, medium-sized enterprises, SME) productivity indicators (gross value-added per capita, sales per capita) with growth indicators (net sales growth rate, operating profit growth rate, net profit growth rate, asset growth rate, employee growth rate). The productivity indexes of companies(large, small and medium enterprises) that received R&D support from government by selecting biotechnology and medical industry (regional business) among the large-area leading projects that were promoted for three years from 2012 (value added per employee, Sales growth, operating profit growth, net profit growth, total assets growth, and employee growth rate). As a result, both the representative flagship industry and the growth leading industries showed an increase in sales per capita, which is an indexes of productivity, over time. The value added per employee, which is the most important productivity index, measures profits attributable to a wide range of stakeholders. The average value of the representative flagship industries is higher than the growth leading industries. We find that government R&D investment has a positive effect on firm performance, as both the total assets growth rate, the net profit growth rate and the number of employees increase. Even in the case of similar industries, we could confirm the difference between industrial classification, company size, and financial characteristics between the growth leading industry and the representative flagship industry. In addition, a t-test was conducted to obtain statistical significance for the analysis. The limitations of this study are that the size of SMEs participating in the project varies, and it is necessary to compensate the difficulty in distinguishing the differences on the error bar. From this research, in the future, it is necessary to set direction for government R&D investment through comparative analysis of 40 industries.

        The literature on the performance of regional university-industry cooperation continues to grow. This research is varied and vibrant, yet large and fragmented. Therefore, the purpose of this review is to examine each of dimensions of regional university-industry cooperation’s performance analysis to describe common across dimensions and to develop an integrative model. We conduct meta-analysis of published papers in SSCI, SCI, and journals registered or candidates registered in the NRF during 7-years period from 2009 to 2015. In this article we first organize the burgeoning the performance analysis of regional university-industry cooperation literature into three streams of research: resource based views, regional innovation networking, and institutional and cultural perspective. Second, we synthesize research findings into a model of factors affecting the regional university-industry cooperation’s performance. This model highlights the distinction between input, output, and outcome based input-output model. Third, we present potential paths - four agendas - for futureresearch based on the concepts and links that are missing or not well explored in the model.

        충청권 지역산업의 디지털 전환 혁신역량 연구: 수도권과의 집단분석을 중심으로

        이유환 한국지역경제학회 2023 韓國地域經濟硏究 Vol.21 No.3

        This study analyzes the relationship between the adoption of digital transformation technologies (under, DX techs) and the innovation performance of manufacturing firms in the Chungcheong region. According to the research findings, first, the adoption of DX techs is found to have a positive relationship with both process and service innovation performance in manufacturing firms. Second, the adoption of DX techs by manufacturing firms is relatively higher for process innovation performance compared to service innovation performance. Third, the impact of DX techs on innovation performance in manufacturing firms is moderated by innovation strategies, although it is observed to be relatively lower in terms of the magnitude of estimated coefficients compared to the direct effects. Fourth, according to the results of the group analysis, it is found that process innovation performance has relatively higher acceptance in the Chungcheong region compared to the capital region, whereas service innovation performance has lower acceptance in the capital region compared to the Chungcheong region. These results can be interpreted as indicating that the Chungcheong region, which has a relatively higher level of manufacturing infrastructure, exhibits higher acceptance of process innovation performance, while the capital region, which has a relatively higher level of service industry infrastructure, shows greater acceptance of service innovation performance.

        코로나19가 기업성과에 미치는 연구: 산업별․지역별․기업규모별 중심으로

        김경애 대한경영학회 2022 大韓經營學會誌 Vol.2022 No.특별호

        Risks arising from accidental and external environmental factors are very difficult to predict. Therefore, there is a limit to preventing or suppressing the occurrence of a risk. Ultimately, how to manage risk when it occurs is important to minimize the damage of risk. Now, in an interconnected business environment, a company’s competitiveness and success no longer depend solely on its own performance. Therefore, the importance of efficient use of up-to-date information on the rapidly changing environment and the ability to respond quickly is increasingly emphasized in business management. Taking full advantage of agility is a way for a company to secure a sustainable competitive advantage while maintaining differentiated competitiveness. Environmental uncertainty changes the dynamics of competition and internal capabilities of an organization, and causes a gap between information already known and newly requested information. Therefore, managers need more monitoring to close the information gap when uncertainty increases. Corona 19 has disrupted the global supply chain and has rapidly shrunk production activities in countries around the world, which has resulted in the world taking measures to halt factory operations and close facilities to prevent the infection and spread of COVID-19. This resulted in the temporary suspension of production activities of enterprises. Under the globalized economy, the shutdown of overseas parts production plants led to the shutdown of domestic finished product plants, which had a chain effect that led to the shutdown of other affiliated companies. In addition, the deterioration of parts supply and demand due to restrictions on human and material exchanges between countries aggravated the setbacks in production activities. Therefore, it is expected that the impact of the COVID-19 depends on the industries, regions, and firm size. Therefore, this paper intends to contain the following contents. First, this study investigated whether COVID-19 had a different effect on the performance(ROA) of each industry for Korean companies under the economic situation with high uncertainty brought about by COVID-19. Second, I thought that COVID-19 would have had an different impact depending on the region. Last organizational competency has the characteristics of promoting and supporting corporate strategy and is a key factor in ensuring sustainable success. It is thought that this will be different for large enterprises and small and medium-sized enterprises, and it is expected that there will be even more differences in times of crisis such as COVID-19. Therefore, we would like to clarify and empirically analyze how the organizational system based on Korean specificity differs in organizational performance depending on the size of the company during COVID-19. As a result of industry-specific analysis, construction, wholesale and retail, lodging and restaurants, transportation (including air transport), agriculture and fishery, education service, business facility management and business support service (including travel) appeared to be lower after the COVID-19 pandemic than before COVID-19. However, only the electricity, gas, steam and water businesses performed better after COVID-19. In the regional analysis, it was found that corporate performance (ROA) in Chungnam, Busan, Daegu, Gyeongnam, Gwangju, and Jeonnam was worse after the COVID-19 pandemic than before COVID-19. The rest of the regions were analyzed as having no difference, and there was no region where performance improved after COVID-19. The results of the firm size analysis showed that the performance of large companies was lower after COVID-19. On the other hand, there was no difference in performance between SMEs before and after COVID-19. 코로나19는 글로벌 공급 사슬을 붕괴시키고 세계 각국의 생산 활동을 빠른 속도로 위축시켰으며, 이로인해 전 세계는 코로나19의 감염 및 확산을 막기 위한 공장가동 중단 및 시설폐쇄 조치를 취했다. 이는 기업들의생산 활동이 일시에 중단되는 결과를 낳았다. 세계화된 경제체제 하에서 해외 부품 생산 공장의 가동 중단은국내 완성품 공장의 생산 중단으로 이어졌고, 이는 다른 관계사들의 조업 중단으로 이어지는 연쇄효과가발생하였다. 또한, 국가 간 인적, 물적 교류 제한으로 인한 부품 수급의 악화가 생산 활동의 차질을가중시켰으며, 생산, 소비, 국가 간 교역 등의 경제활동 위축은 우리나라를 비롯한 전 세계 경제를 급속도록악화시키는 영향을 미쳤다. 이번 코로나19로 인해 산업별, 지역별, 기업규모별로 다른 영향을 미쳤을 것이라예상된다. 그리하여 본고에서는 코로나가 기업성과에 대해 미치는 효과가 산업별, 지역별, 기업 규모별로어떠한 영향을 미쳤는가를 분석해 보고자 하였다. 첫째, 본 연구는 최근 코로나19가 가져온 불확실성이 높은경제 상황과 급격하게 악화된 생산 활동하에서 우리나라의 기업들에게 코로나19는 산업별 성과에 영향을미쳤는지 알아보았다. 산업별 분석결과, 건설업, 도매 및 소매업, 숙박 및 음식점업, 운수업(항공운송업 포함), 농업 및 어업, 교육서비스업, 사업시설관리 및 사업지원 서비스업(여행업 포함)이 코로나19 이전과 비교해서이후에 성과가 낮아진 것으로 나타났다. 그러나 유일하게 전기, 가스, 증기 및 수도사업에서는 코로나19 이후에성과가 더 높게 나타났다. 둘째, 코로나19는 지역에 따라 영향을 미쳤을 것이라고 보았다. 그 결과 지역에서는충남, 부산, 대구, 경남, 광주, 전남에서 기업성과(ROA)가 코로나19 이전보다 코로나19 팬데믹 이후에기업성과가 나빠진 것으로 나타났다. 나머지 지역은 차이가 없는 것으로 분석되었고, 코로나19 이후에 성과가높아진 지역은 한 곳도 없었다. 셋째, 조직역량은 기업전략을 촉진 및 지원하는 특성을 가지고 있으며지속가능한 성공을 보장하는 주요요소이다. 이는 대기업과 중소기업에 따라 다를거라고 생각되며 코로나19와같은 위기시에는 더욱 차이가 있을거라고 보았다. 따라서 한국적 특수성에 기반한 조직의 시스템적 체계가코로나19시에는 기업규모에 따라 조직성과에 있어 어떻게 다른지 실증 분석하여 밝히고자 하였다. 기업 규모분석결과는 대기업에서 코로나19 이후에 성과가 더 낮아진 것으로 나왔다. 반면 중소기업에서는 코로나19 이전과 이후에 성과 차이가 없는 것으로 나타났다.

        지역혁신체제관점에서의 대전·충청지역 중소기업 혁신성과 결정요인에 관한 실증적 연구

        김영진(Young-Jin Kim),김병근(Byung-Keun Kim) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.9

        본 연구는 대전충청지역의 지역혁신체제의 특성 및 지역 내 기업 혁신성과 결정요인을 규명하는 것을 목적으로 한다. 분석의 대상지역인 대전충청지역은 대학, 연구소와 같은 연구기반과 대규모의 하이테크 산업단지, 이들 지원하는 혁신지원네트워크를 잘 갖추고 있다. 기존의 지역혁신체제 연구의 한계점을 보완하기 위해서, 기업의 내부적 요인인 내부역량과 외부적 요인으로서 지역혁신역량을 모두 고려하여, 이들이 기업의 혁신성과에 미치는 영향에 대해 분석한다. 기업의 연구개발역량, 마케팅역량, 기업가지향성과 지역혁신역량이 혁신성과에 영향을 미치는 지와 지역혁신역량이 내부역량들과 기업가지향성과 혁신성과의 관계를 조절하는 가를 분석하였다. 실증분석 위해 대전 충청지역 중소기업을 대상으로 설문조사를 시행하여 120개의 설문을 회수 하였으나 부실응답 56개를 제외한 64개의 설문지가 연구 데이터로 사용되었다. 요인분석과 위계적 회귀분석을 활용하여 실증 분석한 결과 기업의 연구개발역량, 마케팅역량, 기업가 지향성으로 측정한 내부역량이 기술혁신성과에 유의한 영향을 미치는 것으로 나타났다. 이는 기업의 내부역량이 혁신의 가장 중요한 요인임을 주장한 기존의 연구결과를 지지하는 것이다. 그런데 기업가지향성은 혁신적이고 진취적인 기업가 지향성만이 혁신성과에 긍정적인 영향을 미치는 것으로 나타났으며 위험감수적 기업가지향성은 혁신성과 영향을 미치지 않는 것으로 확인되었다. 지역혁신역량도 기업 혁신성과에 통계적으로 유의하게 영향을 미치는 것으로 나타났다. 또한 지역혁신역량은 위험감수적 기업가지향성과 혁신성과의 관계를 조절하는 것으로 확인되었다. This study aims to identify the characteristics of the regional innovation system(RIS) and the determinants of innovation performance of SMEs. Data were collected from a questionnaire survey on 64 SMEs in the Daejeon and Chungcheong regions to uncover the relationship between capabilities, regional innovation capacities and innovation performance. The moderating effects of regional innovation capacities on the relationship between firms" innovation capabilities and performance were also tested. Empirical results revealed that R&D, marketing and entrepreneurial orientation had positive effects. The moderating effect of regional innovation capabilities on the relationship between entrepreneurial orientation (risk taking) and performance was also confirmed.
