[연구목적] 본 연구의 목적은 창업계획이 있는 소상공인에게 창업교육을 수행하는데 있어서, 교육서비스 품질, 교육만족도, 신뢰성 및 추천의도의 구조적 인과관계를 분석하여, 향후 창업교육서비스 품질 향상을 위한 장기적인 창업교육전략을 수립하는데 있다.[연구방법] 본 연구의 방법은 교육서비스 품질, 교육만족도, 신뢰성, 추천의도의 구조적 인과관계를 살펴보기 위해 구조방정식 모형(SEM)을 사용하였다.[연구결과] 본 연구의 결과는 다음과 같다. 첫째, 교육서비스 품질의 요소인 강사품질, 시설품질 및 교육품질은 교육만족도에 영향을 미치는 것으로 분석되었다. 둘째, 교육서비스 품질과 신뢰성과의 관계에서는 교육서비스 품질인 강사품질과 교육품질은 신뢰성에 영향을 미치고 있지만, 시설품질은 영향을 미치고 있지 않은 것으로 분석되었다. 셋째, 교육만족도와 신뢰성과의 관계에서는 창업자가 창업교육에 대해 만족을 하면, 창업자가 강의에 대해 신뢰를 하는 것으로 분석되었다. 넷째, 교육만족도와 추천의도와의 관계에서는 창업교육생들의 교육만족도가 추천의도에 영향을 미치는 것으로 분석되었다. 다섯째, 신뢰성과 추천의도와의 관계에서는 신뢰성은 추천의도에 영향을 주는 것으로 분석되었다.[연구의 시사점] 창업환경의 변화가 심할수록 창업교육에 필요한 교육과 시설에 대한 교육서비스 품질관리가 필요한 요소로 대두 되고 있다. 창업교육기관에서는 공급자 중심의 교육 서비스 제공에서 교육을 받는 창업자 중심의 서비스 제공으로 교육환경이 전환되어야 한다. 또한 창업교육의 다양성으로 인해 교육내용, 교육방법 뿐 아니라 교육시설, 강사자질, 교육기자재, 직원서비스 등에 관련한 교육서비스 품질관리가 필요하다. the service quality, satisfaction, reliability and recommendation intention of the education which will be provided to small enterprises who plan to start up business in an effort to help them establish long-term educational strategies with improved quality.[Methodology] The structural equation modeling (SEM) was used in the present study as a means to examine the structural causality relationship among the service quality, satisfaction, reliability and recommendation intention of education.[Findings] For this objective, an analysis was conducted in this paper to determine the structural causality relationship among the service quality, satisfaction, reliability and recommendation intention of such education, which resulted in the following outcomes:first, it was known from the analysis that the qualities of educational service including those of lecturers, facilities and education itself could influence the educational satisfaction;second, with regard to the relationship between the educational quality and reliability, the quality of lecturers and education turned out to affect the reliability, while that of facilities didn’t;third, the analysis found that, as for the relationship between the educational satisfaction and reliability, start-up enterprises might put reliability on lectures once they could be satisfied with start-up education;fourth, the educational satisfaction of trainees with start-up education would exercise impact upon recommendation intention; and fifth, as for the relationship between reliability and recommendation intention, it became evident from the analysis that reliability could have influence on recommendation intention.[Implications] Based on the above results, following implications could be presented. As the conditions for start-up enterprises change drastically, it appears essential to control the service quality and facilities for education of start-up enterprises. In this respect, the educational institutions for start-up enterprises should endeavor to change the educational paradigm from supplier-oriented service to start-up-oriented one. In view of diversified start-up education, it may also be necessary to control the educational service quality including not only the contents and methods of education but also the educational facilities, qualities of lecturers, educational equipment as well as conduct of faculty members.

[연구목적] 본 연구는 중국의 전자 상거래 기업을 대상으로 경영효율성을 측정하고, 경영효율성에 영향을 미치는 환경요인이 효율성에 어떠한 영향을 미치는지 분석함으로써 전자상거래 기업의 경영효율성을 결정하는 요인을 추정하고, 그 결과를 바탕으로 경영효율성의 평가와 운영의 효율성을 제고하는 데 연구의 목적이 있다. [연구방법] SBM-DEA 모형을 이용하여 상장 된 42개 전자상거래 기업의 경영효율성을 2단계 DEA 모형을 적용한 Tobit 회귀분석을 수행하였다. [연구결과] 상장 전자 상거래 기업들은 전체 기술효율 평균값 0.518로 나타나, 효율성의 향상시킬 수 있는 여지가 있는 것으로 분석되었다. 또한 전체적으로 전자 상거래 기업들은 과도 투입이나 산출 부족의 문제가 존재하는 것으로 분석되었다. 또한 총 자산 회전율, 순이익 및 브랜드 가치 인식이 전자상거래 기업 운영의 효율성에 중요한 요소로 분석되었다. [연구의 시사점] 전자 상거래 기업들은 경영의 효율성을 추구하기 위해서는 기술 및 경영 수준을 지속적으로 개선해야 하고 경영 자원 배분을 최적화하며, 기술 효율성을 지속적으로 개선할 필요가 있음을 시사할 수 있다. [Purpose] This study measured the operating efficiency and analyzed the environmental factors affecting operational efficiency by using 42 listed e-commerce companies in China. The purpose is to evaluate the efficiency of e-commerce operations and improve the efficiency of e- commerce operations. [Methodology] This study used the SBM-DEA model to determine the operating efficiency of 42 listed e-commerce companies. The 2-stage DEA model used the Tobit regression model for regression analysis. [Findings] The average technical efficiency of listed e-commerce companies is 0.518, indicating that there is room for improvement in efficiency. Overall, e-commerce companies have problems with excessive investment or lack of output. In addition, total asset turnover, net profit and brand value perception are important factors in operational efficiency. [Implications] In order to pursue management efficiency, e-commerce enterprises need to continuously improve their technology and management level, optimize management resource allocation, and continuously improve technical efficiency.
