사회적 경제 기업 평가모형의 가중치 분석 : 신용보증기금의 일반형 평가모형을 기준으로
김건훈,김형도 신용보증기금 2023 중소기업금융연구=Journal of SME finance Vol.43 No.3
사회적 경제 기업의 경제적 자립을 지원하기 위한 평가모형이 코로나19 이후 변화된 사회 현실과 점차 늘어나는 사회적 경제 기업의 경제적 상황을 충분히 담아내지 못하고 있다. 이런 방향에서 본 연구는 신용보증기금의 사회적 경제 기업 일반형 평가모형을 기준으로 사회적 경제 기업의 경제적 자립 지원을 위한 기업 평가항목을 분석하였다. 주요 이해관계자인 신용보증기금, 금융기관 그리고 사회적 경제 기업을 대상으로 조사한 후, AHP 방식으로 가중치를 결정하고, 이를 기존의 가중치와 비교하였다. 분석결과, 기존의 평가모형에 비하여 기업 미션의 사회적 가치와 직무교육 노력의 중요 성이 더 높게 평가되었으며, 이러한 변화에 가장 많이 영향을 준 이해관계자는 사회적 경제 기업이 었다. 본 연구의 결과는 신용보증기금의 일반형 평가모형 개선에 기여할 수 있을 뿐만 아니라, 사회 적 경제 기업의 경쟁력 확보와 자립을 위한 연구에도 활용될 수 있다 It has been raised that the existing evaluation models for promoting the economic self-reliance of social economy enterprises do not adequately capture the changing social reality and the challenging economic situation of social economy enterprises gradually increasing after COVID-19. In the direction, this study analyzed the evaluation factors for supporting the economic self-reliance of social economy enterprises, focused on the general evaluation model of KODIT(Korea Credit Guarantee Fund) for social economy enterprises. We collected opinions from three major stakeholders: KODIT, financial institutions, and social economy enterprises. We then used the Analytic Hierarchy Process(AHP) to determine the weights and compared them with the existing weights. The analysis results showed that compared to the existing evaluation model, the social value of enterprise missions and the importance of job training efforts were evaluated more highly, and the stakeholders that had the most significant influence on these changes were social economy enterprises. The results of this study can contribute not only to the improvement of the general evaluation model of KODIT but also to research aimed at enhancing the competitiveness and self-reliance of social economy enterprises.

In response to the national policy for the reduction of CO2 gas emissions and the dissemination of renewable energy resource facilities, the disseminated capacity of wind turbines is steadily expanding in Korea. However, to facilitate more realistic national dissemination planning, a more scientific basis for domestic wind potential and actual installation capability must be established. In this regard, a number of previous studies have provided details on the key parameters associated with wind energy potential. Among the major key points regarding wind energy potential is the array power density (APD) of wind turbines. However, this may be determined under certain ambiguous conditions associated with technical uncertainties. In general, an APD value of 5 MW/km2 is applied in Korea and a number of previous studies have reported results based on the application of APDs of 3 to 5 MW/km2. Given the diverse range of factors that can potentially influence the accuracy of the APD determinations for wind turbines, it is necessary to establish a more detailed and scientific basis for the determination of APD. In this study we seek to provide such a basis. To the best of our knowledge, this is the first study to assess the scientific basis of APD based on an examination of representative wind turbines, with respect to several technical specifications relating to wind speed, wind direction and IEC class conditions. We aim to scientifically analyze the effects of the performance characteristics of wind turbines on the APD, which is also the most important factor for an assessment of wind energy potential, and will contribute to establish an accurate technical basis for determination of APDs. On the basis of the findings in this study, we quantitatively identified the effective parameters for the determination of APD, which can be applied to facilitate an accurate determination of wind energy potential. Furthermore, these parameters have potential application as key variables in renewable energy data platforms and provide a technical reference for wind energy potential work area.

The installed capacity of wind turbines in KOREA are growing and enlarging by the central government's support program. Thus, the importance of power performance verification and its uncertainty analysis are recognizing rapidly. This paper described the power testing results of a 3MW wind turbine and analysed an uncertainty level of measurements. The measured power curves are very closely coincide with the calculated one and the annual power production under the given Rayleigh wind speed distribution are estimated with the 3.6~12.7% of uncertainty but, in the dominant wind speed region as 7~8m/s, the uncertainty are stably decreased to 6.3~5.3%
