  • 중소기업은 상대적으로 작은 규모와 제한된 자원으로 인해 혁신의 효율성과 효과성을 높이기 위해 개방형 혁신에 참여한다. 기존 연구들은 중소기업이 수행하는 다양한 유형의 개방형 혁신활동의 성과효과를 연구하였으나, 특히 결합형 개방형 혁신활동의 성과효과에 대한 결과가 혼재한 상황이다. 이에 본 연구는 중소기업의 결합형 개방형 혁신협력활동을 'R&D 협력활동'과 'R&D 이외의 협력활동'으로 세분화하여, 각 활동이 기업의 혁신성과와 재무성과에 미치는 효과를 Heckman의 2단계 모형을 적용하여 검정하였다. 분석 데이터로는 과학기술정책연구원(STEPI) 주관의 국가승인통계인 '2020년 한국기업혁신조사: 제조업 부문' 자료를 활용하였다. 분석결과 중소기업의 R&D 협력활동은 시장최초 상품혁신 성과에만 유의미한 정(+)의 효과가 있고, R&D 이외의 협력활동은 상품혁신, 비즈니스프로세스혁신, 시장최초 상품혁신, 자사최초 상품혁신 모두에 유의미한 정(+)의 효과가 있는 것으로 나타났다. 하지만 두 유형의 혁신협력활동 모두 재무성과에는 유의미한 효과가 없는 것으로 나타났다. 또한 이러한 혁신협력활동의 성과효과는 중소기업 내에서도 기업규모에 따라 다른 것으로 나타났다. 본 연구는 중소기업 맥락의 개방형 혁신 연구에 이론적으로 기여하며, 중소기업 경영자의 혁신전략 수립 및 관련 정책입안자의 정책 방향 도출에 참고가능한 지침을 제공한다.

  • Purpose - This study aims to analyze the influence of South Korea's outward foreign direct investment (OFDI) under the effect of both multinational enterprises' (MNEs) investment motivation and host country institutions. Some suggestions are put forward with regard to South Korean MNEs participating in and integrating into the fierce and changeable world of international market competition. Design/methodology - The basic hypotheses are that MNEs' investment motivations and the host country's superior institutions both boost South Korea's OFDI in those host countries. South Korea's OFDI is divided into investment choice stage and investment scale stage. A Heckman two-stage selection model is established for empirical analysis, using the panel data of South Korea's OFDI and related variables, from 2002 to 2019. Findings - (1) The influence on the investment scale of South Korea's OFDI is more regular and noteworthy than the influence on investment choice. (2) In the investment scale stage, there are obvious motivations to seek markets, labor force and superior technology, but not natural resources. (3) In the investment scale stage, the South Korea's OFDI is more obviously attracted by the host country's superior political institutions, economic institutions and legal institutions, but not cultural institutions. Originality/value - The choices of variables and uses of model expand the theoretical basis and empirical method of OFDI research. The results of the empirical study also provide some reference for the transnational investment of South Korean MNEs and the investment policy formulation of the South Korean government.

  • This research investigates the impact of vocational training on wages of ethnic minority labors in emerging countries; Vietnam is the case study. The study uses secondary data from 2014 to 2018 collected through Vietnam Household Living Standards Surveys (VHLSS) conducted by the General Statistics Office. In order to analyze the impact of vocational training on wages of ethnic minority areas in Vietnam, this research creates ethnic area variables. According to Vietnamese regulations, ethnic areas are communes of 51 different provinces, inhabited by ethnic minority people. The statistics from VHLSS in 2018, show that the proportion of labors of working age with a certificate was 22.5%. The research employs Heckman Sample Selection Model to estimate the impact of vocation training on wage of labors in ethnic minority areas. The results show that vocational training plays a crucial role in improving the wages of ethnic minorities and has a positive impact. However, apart from the achieved outcomes, vocational training and job creation for ethnic minorities are not without limitations and shortcomings. Based on the findings, some recommendations to ethnic minority labors, enterprises and the Government are proposed to encourage participation in vocational training for the purpose of promoting the efficiency of the labor market.

  • Purpose: The purpose of this study was to examine the association between utilization of home care services under the national long-term care insurance system and family caregiver distress. Methods: A secondary data analysis was conducted in this study using data collected in 2011 and 2012 from the Korean version of International Resident Assessment Instrument (interRAI) Home Care assessment system. The study sample included 228 clients receiving community based home care and their family caregivers in Korea. Descriptive statistics, $x^2$ test, t-test, and Heckman selection model analysis were conducted using SAS 9.3. Results: Presence of family caregiver distress was significantly associated with days of nurse visits (${\beta}$=-.89, p=<.001) and home helper visits (${\beta}$=-.53, p=.014). Level of caregiver distress was also significantly associated with days of nurse visits (${\beta}$=-.66, p=.028). Other factors which were significantly associated with caregiver distress were depression, cognitive function, inadequate pain control, social support for older adult, and caregiver relationship to the older adult. Conclusion: The results of this study show that visiting nurse service and appropriate support programs for Older Adults and family caregivers experiencing caregiver distress should be developed and provided to families based on the health care needs of older adults and their family caregivers for effective and sustainable home care.

  • Korea has become the highest nitrogen balance (228 kg/ha) among 34 OECD member countries, and has the stigma of being a 'Nutrient overload country' as of 2019. Accordingly, research on the derivation and utilization of nutrient balance indicators and the 'regional nutrient management system' are being promoted to improve Korea's nutrient balance. It is necessary to support these policies and studies, form a public consensus on improving the nutrient balance, and evaluate the function of the public benefit. This paper aims to estimate the public benefit value of improving the nutrient balance based on an analysis of consumers' willingness to pay and recognition of Korea's nutrient excess for 600 consumers nationwide. As results, 21.2% of the respondents said they were aware of excessive nutrients in Korea, and 76.7% of the respondents said they were aware of the need for nutrient management. The average amount of intention to pay for the improvement of three pollution (soil, water quality, and air) that can occur due to a nutrient overload was ₩2,321.1 for soil pollution improvement, ₩2,391.2 for water pollution improvement, and ₩2,377.9 for air pollution improvement. The average willingness to pay for the three pollution reduction was ₩6,002.3. These results are expected to be used to form a public consensus on the balance of payments and to establish measures to enhance public interest values in the future.
