In recent business environments, the competition among firms is shifting from the competition based on individual firm only to the competition based on alliance of firms. This is because it is not easy for a firm to perform all functions which consumers want. Thus, it is more effective to combine core competencies of different firms based on a strategic partnership. It is essential to establish a strategic partnership and this strategic partnership is a key success factor in PSS(Product-Service System) which combines products and services. In this paper, we propose a profit sharing model for PSS partnership. We first analyze customer's utility using Cobb-Douglas utility function and then propose the PSS profit sharing ratio considering functionalities and cost structures based on the combination ratio of PSS. This paper helps firms to develop partnership strategies for PSS.

This study analyzed efficiency by utilizing DEA analytical technique centering on materials for 2009 of 20 major university hospitals in capital area. Input variables were utilized professor & full-time doctor, resident, nurse & number of bed hospitals. Output variables were analyzed by dividing number of annual outpatients & number of annual inpatients, and annually total outpatient profit & inpatient profit into a model of the standard for number of patients and the standard for medical profit. DEA analysis was elicited efficiency score by applying CCR, BCC, BFG, scale profit, and SE model. Through t-test after eliciting efficiency score, the implications were suggested by comparing efficiency between DMU in Seoul and DMU in capital area, by comparing between high-class general hospitals and general hospitals, and by comparing between high-class general hospitals in Seoul and 5 big hospitals. As a result of analysis, the major university hospitals in capital area showed high efficiency as a whole close to "1," but indicated low efficiency relatively in CCR field. Thus, the expansion in scale within capital area was indicated to reach the limit. Second, in a model of analyzing the standard for number of patients, the medical institutions, which are being operated efficiently, were indicated to be 10 DMUs. In the standard for medical profit, 12 DMUs were analyzed to be operated efficiently. Third, the efficiency in general hospital was higher than high-class general hospital. Thus, the efficiency of operation was indicated to be more important than scale. Also, large high-class hospitals(big 5) where are located in downtown Seoul showed the higher efficiency than other general high-class general hospitals, but were indicating very low efficiency in some DMUs. Fourth, as a result of generalizing and evaluating the number of patients and the medical profit, the efficient DMU was indicated to be more when analyzing on the basis of medical profit than the standard for number of patients. Thus, major university hospitals in capital area were indicated to make more effort for section in medical profit. Based on the analytical results of efficiency, a strategy for reinforcing efficiency in inefficient DMU was indicated to be needed a strategy of creating customers for promoting number of patients and a strategy for making operation efficient for increasing profitability.

On account of multiple causes, including prolonged global economic crisis, addressing environmental pollution and the advent of hyper-connected society, a new paradigm called 'sharing economy' has rapidly emerged. Many startups have attempted to build promising business model based on the sharing economy concept. Nevertheless, successful cases are still very rare in the global level, except for Uber and Airbnb cases. Therefore, this study analyzes necessary causes and sufficient causes for successful settlements in the market through a comparative case analysis on digital matching firms in the sharing economy businesses. For the case study, we compare five successful cases (Uber, Airbnb, Kickstarter, TaskRabbit and DogVacay), three failure cases (Homejoy, Ridejoy and Tuterspree) and a platform cooperativism case (Juno) in accordance with six value attributes of business model including value proposition, market segment, value chain, cost structure and profit potential, value network and competitive strategy. We apply Boolean method to support controlled comparison and eliminate unnecessary attributes. The Boolean analysis result shows that value proposition, cost structure and profit potential, value network and competitive strategy are the essential attributes. Furthermore, the result indicates that each attribute is a necessary condition, where all four conditions should be met simultaneously in order to be successful. With this result, we discuss essential consideration for those who are planning startup based on the sharing economy business model.

It seems a common sense that corporate social responsibility (CSR) is a key driver to attain business sustainability. Nevertheless, there has been little research on the performance of socially responsible activities, including economic and environmental responsibility activities in internationally diversified firms. The purpose of this study was to evaluate the effects of CSR activities on management performance. For this evaluation, an empirical analysis was conducted with a total of 2,520 cases, selected from companies listed on the Korea Composite Stock Price Index market for six years from 2013 to 2018. As proxies for management performance, financial date such as a total asset net profit ratio and a total asset-operating ratio were used. A multivariate regression analysis was conducted to test hypotheses. The results of this analysis indicated that firms in the CSR outstanding group are significantly higher than other groups in management performances. In addition, CSR activities of internationally diversified firms positively influence their total asset net profit ratio and total asset-operating ratio. The results suggested that CSR activities of these firms can play a significant role in enhancing management performances amid the economic status of Korea, where a degree of export dependency is high.

Bankruptcy is indicated by the inability of the company to meet its maturity obligations. The Covid-19 pandemic has had a terrible impact on the economy and businesses. The aim of this study to determine the effect of the ratios of activity, growth, leverage, and profitability in predicting bankruptcy projected by earnings per share (EPS). The sample of this research was non-banking financial sector companies listed on the Indonesia Stock Exchange in 2015-2019 and the purposive sampling technique was used. The data analysis method used was the logistic regression method to test the hypotheses. Company growth shows the company's ability to manage sales and generate high company profits, as such, the probability of the company experiencing bankruptcy will be lower. The results of this study showed that the debt to assets ratio (DAR), debt to equity ratio (DER), and return on assets (ROA) can predict bankruptcy. Meanwhile, this research found that the total assets turnover (TATO) ratio, sales growth, and net profit margin (NPM) cannot be used to predict bankruptcy.

본 연구는 유사한 혹은 동일한 산업에 속해 있는 두 기업이 공동사업(joint venture)을 수행하는 과정에서 이익을 분배하는 메카니즘을 분석한다. 두 기업이 동의할 수 있는 '공정한' 이익분배와 함께 자원배분의 효율성을 달성할 수 있는 의사결정구조를 모색한다. 공동사업은 한 기업이 설비를 제공하고, 다른 기업이 제품을 생산하고 판매하는 형태로 진행되는 경우를 상정하고 있다. 본 연구의 분석결과는 공동사업의 의사결정 구조를 적절히 고안하면 사회적 효율성을 충족하는 균형에 도달할 수 있음을 시사한다. 동일 기업집단 내의 공동사업과 같이 이익분배(이전가격)가 사전에 정해져 기업들의 사적 유인이 통제될 수 있는 상황 뿐 아니라, 독립적 기업들의 공동사업에서도 판매기업이 단독으로 이전가격을 결정하는 구조를 배제하면 효율적인 결과를 낳을 수 있음을 보인다.

발생주의 회계 하에서는 경영자의 재량적 판단에 따라 회계 보고가 이루어질 가능성이 있으므로, 현금주의 회계에 비해 재무제표의 신뢰성이 낮게 평가될 수 있다. 본 연구의 목적은 이연법인세 계정의 증감을 통해 경영자의 이익조정 가능성을 판단해 보는 실증분석을 수행하는 것이다. 본 연구의 실증분석을 위해 이연법인세자산에서 이연법인세부채를 차감한 이연법인세 순액을 이연법인세순자산으로 정의하여 이연법인세순자산이 전년 대비 증가되면 '1', 감소되면 '0'인 더미변수를 종속변수로 사용하였다. 한편, 관심변수는 재량적 발생액과 전년 대비 총자산순이익률(ROA: Return on Assets, 이하 ROA) 증감을 사용하였으며, 로지스틱 회귀분석을 실시하여 관심변수와 종속변수 간의 관련성을 규명하였다. 본 연구의 결과는 다음과 같다. 첫째, 재량적 발생액이 클수록 전년 대비 이연법인세순자산이 감소하였다. 둘째, ROA가 증가한 경우와 당기순이익이 '0'보다 큰 경우에만 ROA와 이연법인세순자산 간에 상호 관련이 있는 것으로 나타났다. 이는 기업이 전년 대비 ROA가 소폭 감소하였거나 소액의 당기순손실이 발생한 경우, 경영자는 전년 대비 사업성과가 개선된 것으로 보이기 위해 소규모의 이익조정을 행했다는 의심을 갖게 한다. 본 연구의 결과, 외부 정보이용자들은 이연법인세 정보를 투자 의사결정에 활용할 수 있을 것으로 기대되며, 감독기관은 기업의 이익조정을 예방하고 적정한 보고를 유도하는 정책을 수립하는데 활용할 수 있을 것으로 기대된다.

민간경비엽은 사설영리기업으로서 영리성을 목적으로 하고 있으며 동시에 범죄예방이라는 사회적 공익을 우선하고 있다. 이러한 측면에서 민간경비업에 대한 영리성과 공익성의 문제가 상충되고 있으며 영리기업이면서도 공익에 대한 관리감독을 받고 있다. 영리기업의 설립조건과 영업활동권은 상법에 명시되어 있으며 자연인으로서 국민적 기본권과 직업선택의 자유는 헌법에 보장되어 있다. 그럼에도 불구하고 민간경비업은 공익이라는 사회적 기능을 이유로 경비업볍에 준하여 설립조건이나 영업활동의 제약, 직업선택의 자유 등에서 제약을 받고 있다. 즉, 영리법인이면서도 헌법조항의 기본권이 무시되고 있으며, 상법상 법인설립기준이나 영업활동보장권을 적용받지 못하고 있는 것이다. 경비업법에 따르면 경비업을 영위하고자 하는 자는 반드시 법적절차에 따라 해당기관으로부터 허가를 받아야 하며 회사를 대표하는 임직원들도 결격사유가 있어서는 안 된다. 그러나 상법상 법인설립의 기준은 1명이상, 업종별 규정에 따라 차이가 있지만 기본적으로는 자본금 100원 이상이면 법적제약을 받지 않고 회사설립을 할 수 있고, 헌법에 보장된 노포권에 따라 영리를 목적으로 한 모든 소득활동은 보장된다. 이에 따라 본 연구는 민간경비업의 특수성에서 비롯되는 공익성과 영리성에 대한 법적 제도적 문제점을 살펴보고자 한다.
