This study used the DEA and Malmquist Productivity Index to analyze the changes in the efficiency and efficiency of domestic department store industry. The data for analysis are from 13 department stores from 2012 to 2016, and input variables are number of employees, total assets, cost of goods sold, and sales management expenses. The model1 is based on the number of employees and total assets, and the model2 is based on the cost of sales and the cost of sales. As a result of the analysis, the efficiency decreased as the model1 was repeated over the years, but the model 1 was higher than the model2 in the average technical efficiency. In pure technological efficiency, model2 has higher average efficiency than model1, and model1 has higher average efficiency in scale efficiency. In the analysis of return to scale the model1 has many department stores with the increasing return to scales, while the model 2 has many department stores with the decreasing return to scale. As a result of the MPI analysis, productivity increased in both models 1 and 2 over the five-year period from 2012 to 2016 on average. Compared with the previous studies, the efficiency of most department stores decreased.

This study is expected to be very useful because it is possible to consistently analyze the impact on the local economy by each region and individual port through the efficiency analysis of each region by analyzing the port export and the efficiency of the local economy. In addition, it is meaningful to improve inefficiencies through flexible responses and efficient methods by identifying changes in the impact on the port industry and the local economy. The analysis results of this study are summarized as follows. First, the 10-year average technology efficiency was the highest in Jeju, and the average technology efficiency in Jeonnam was the lowest. The average technological efficiency excluding port exports was highest in Ulsan and lowest in Chungnam. In Jeju, Gangwon, and Chungnam, port exports had a significant impact on the local economy, and in Busan, Incheon and Ulsan, port exports had little effect on the local economy. As such, it was found that in regions with a large proportion of other industries that could affect the local economy, such as Busan, Incheon, and Ulsan, the effect of port exports on the local economy was small. Second, in terms of 10-year average net technology efficiency, Jeju had the highest and Jeonnam had the lowest. Even when the size of Gangwon is excluded, port exports had a significant impact on the local economy. In addition, in Busan, Incheon, and Ulsan, where the proportion of industries other than ports is large, such as technological efficiency, the effect of port exports on the regional economy was small. This result means that port export value has little correlation with efficiency in regions where industries such as manufacturing have grown. Third, most of them show high efficiency in terms of scale efficiency, and in Chungnam and Jeju, port exports had a great impact on the local economy. Fourth, the model including port exports showed higher technical efficiency and net technical efficiency, and there was no significant difference in scale efficiency. Fifth, the efficiency of the model including port exports was confirmed to be high for 10 years. As such, the efficiency is greatly affected by the local economy or industry, and in particular, it can be seen that the port exports have a large impact on the local economy. Sixth, the 10-year average Malmquist productivity index showed the largest change in efficiency in Gyeongnam, and the smallest change in efficiency in Busan. Changes in technology efficiency have a large impact on efficiency changes, so it was confirmed that regions with low MPI can narrow the gap with other regions by increasing MPI through the spread of business management technology.

65세 이상 인구의 미충족 의료에 미치는 영향 요인에 관한 연구 : 부산, 경남지역을 중심으로

장찬민 한국산업경제학회 2024 산업경제연구 Vol.37 No.3

우리나라는 고령화가 빠르게 진행되고 있으며 그중 노인들은 의료 서비스를 제대로 받지 못하고 있는데 그 이유로는 다양한 것으로 나타났다. 65세 이상 인구의 미충족 의료에 미치는 영향을 알아보고자 2019년과 COVID-19가 어느 정도 소강상태로 진입한 2022년으로 구분하여 연구를 진행하였다. 본 연구에 참여한 대상자를 미충족 의료가 있는 군과 없는 군으로 나누어 특성을 비교한 결과 년도, 성별, 연령, 학력, 가족 유형, 기초생활수급자, 월소득, 주관적 건강 상태 흡연, 신체활동, 아침 식사, 수면시간, 우울감, 스트레스, 보건소 이용에 유이한 차이가 나타났다. 미충족 의료가 있는 군의 비율로는 2019년보다 2022년이 더 높게 나타났다. 특히 2019년과 2022년의 미충족 의료에 미치는 영향 요인에는 차이가 있었으며, 이는 2020년 초반부터 전 세계를 강타한 COVID-19 팬데믹은 건강 서비스의 이용 패턴을 크게 변화시켰으며, 팬데믹은 사람들의 건강에 대한 인식과 태도에 중요한 변화를 불러왔으며, 예방적 건강 관리와 면역력 강화에 대한 관심이 증가했으며, 이는 의료 서비스에 대한 수요와 이용 패턴에 영향을 미쳤을 수 있다. 부산지역과 경남지역에 대한 지역별 미충족 의료에 대한 비교 분석을 통해, 지역별 차이가 있었고 부산지역보다는 경남지역에서 건강 서비스 접근성과 지역 사회 경제 상황 등 미충족 의료에 미치는 영향이 있었다. 연도별로 2019년과 2022년의 미충족 의료 추세를 분석하여, 사회 경제적 변화나 보건정책 변화 그리고 팬데믹으로 인해 미충족 의료에 미치는 영향을 파악할 수 있었다. Korea is rapidly aging, and the elderly among them are not receiving proper medical services. There are various reasons for this. To determine the impact on unmet medical care among the population over 65 years of age, a study was conducted in 2019 and 2022, when COVID-19 entered a lull to some extent. The subjects who participated in this study were divided into groups with and without unmet medical care, and the characteristics were compared. Year, gender, age, education, family type, basic livelihood recipient, monthly income, subjective health status, smoking, physical activity, breakfast, sleep. Significant differences were found in time, depression, stress, and use of public health centers. The proportion of counties with unmet medical needs was higher in 2022 than in 2019. In particular, there were differences in the factors affecting unmet medical care in 2019 and 2022, as the COVID-19 pandemic, which has struck the world since early 2020, has significantly changed the patterns of use of health services, and the pandemic has affected people's health. has brought about significant changes in perceptions and attitudes towards health and increased interest in preventive health care and strengthening immunity, which may have influenced patterns of demand for and use of health services. Through a comparative analysis of unmet medical care by region in the Busan and Gyeongnam regions, there were regional differences, and there was an impact on unmet medical care, such as accessibility to health services and local social economic conditions, in the Gyeongnam region rather than the Busan region. By analyzing trends in unmet medical care in 2019 and 2022 by year, we were able to identify the impact of socioeconomic changes, health policy changes, and the pandemic on unmet medical care.

企业借壳上市路径选择的策略研究

김령,김순희,장찬민 한국국제회계학회 2020 국제회계연구 Vol.0 No.91

There are two ways for listed enterprise, one is a general way to go public -IPO, and another is a special way to go public- backdoor listing. As an important reflect of information quality, enterprises implement different earnings management means they would have different effect on the future performance of enterprises before and after go public. According to the traditional concept, backdoor listed enterprises are not as good as those issued by IPO in terms of profitability and information quality, only those enterprises that cannot be listed through normal channel will choose backdoor listing. In view of the fact that few companies have completed backdoor listing before 2011, we select relevant data of Chinese listed companies of 2011-2015 to ensure that all the sample listed companies have completed backdoor listing procedures and issued the announcement of asset restructuring. Compared with the direct listed companies, investors and market take a dim view of the reverse merges’ future performance. The result shows that it is difficult for regulators and investors to identify the earnings management behavior of before and after the shell. Compared with the direct listed companies, investors and market take a dim view of the reverse merges’ future performance. The overall results show the earning quality of reverse merges before go public is higher than that after go public. In addition, the earning quality of IPOS is higher than that of reverse merges from earning management perspective. 企业上市方式有两种,一种是大众化上市方式—IPO发行,另一种为特殊上市方式—借壳上市。不管是哪种形式的上市,企业上市前都会发生盈余管理水平的变化,因此盈余管理是企业信息质量的重要体现,企业在上市前采取的手段不同,对企业未来业绩的影响也会不同。传统的观念认为,借壳上市的企业不如IPO发行的企业,在盈利能力或者信息质量等方面,因为只有那种无法通过正常手段上市的企业,才会选择借壳上市的模式。本文研究目的是分析IPO上市的企业及借壳上市的企业,它们各自在上市前后发生的盈余管理方式的变化,是通过真实盈余管理还是应计盈余管理的手段,从而判断借壳上市到底是否可取的,是否借壳上市的企业质量真不如IPO发行企业。 鉴于2011年之前完成借壳上市的公司较少,本文选取了2008年至2017年的企业年度样本数据,确保了样本的上市公司均完成了借壳上市程序并且发布了资产重组公告。通过真实盈余管理及应计盈余管理指标,分析了IPO上市的企业及借壳上市的企业,它们各自在上市前后发生的盈余管理方式的变化。研究结果发现,选择借壳上市的企业并不是更差的企业,实际上,借壳企业上市后的盈余管理水平显著低于上市前,并且借壳上市公司的盈余水平,总体上低于IPO公司。监管机构和投资者很难识别借壳前后的盈余管理行为,与IPO上市企业相比,投资者和市场都对借壳企业的未来业绩表现持怀疑态度。我们研究结果表明借壳上市的企业未必不如IPO发行企业,如果投资者只看上市途径来判断企业的好坏,将影响正确的投资判断。
