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.

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.

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。

우리나라 보험산업 인적자원의 질적 개선과 효율성변화

나호수(Nah Ho Soo),장찬민(Jang Chan Min),이명진(Lee Myung Jin),아사모브 라브샨(Asamov Ravshan) 한국인적자원관리학회 2017 인적자원관리연구 Vol.24 No.4

본 연구는 우리나라 보험산업 인적자원의 질적인 개선이 효율성의 변화에 어떤 영향을 미치는지를 분석하고자 한다. 인적자원의 개선은 산업의 교육투자 정도를 반영하는 척도로서 산업에 투입된 인적자원에 포함된 교육투자를 반영하는 것으로 이를 반영하는 교육기간을 기본변수로 하여 우리나라 보험산업에의 인적자원이 교육을 통한 질적인 향상으로 인하여 효율성에 미치는 영향을 분석하고자 하였다. 효율성을 측정하는 방식으로는 자료포락방식(DEA)을 이용하여 한국 생명보험산업과 손해보험산업의 효율성을 측정하였다. 효율성의 변화에 대해 영향을 주는 인적자원의 질적인 개선과 기타 요인들의 영향을 분석하였다. 우리나라 보험산업에서는 전체적으로 상대적 효율성이 증가추세를 갖고 있었고 효율성변화에 영향을 주는 요인으로 인적자원의 질적인 개선이 손해보험산업에서는 효율성 증가에 기여하는 결과로 나타나고 있으나 생명보험산업에서는 효율성에 부정적 영향을 주는 것으로 나타나고 있다. 기타 요인으로 무역자유화에는 두 산업에서 매우 큰 영향을 받는 것으로 나타났다. 정책적 함의는 우리나라 보험산업 인적자원의 질적인 개선의 영향이 손해보험산업과 생명보험산업에 다르게 나타나고 있으므로 인적자원 개선을 위한 차별화된 대응방안이 필요하다는 점이 지적되고 인적자원의 질적인 개선을 통한 보험산업의 경쟁력 제고방안에 대한 차별화된 정책적인 대응이 요구된다. By using data envelopment analysis(DEA) this research study measures the efficiency of the Korean life and non-life insurance industry and the effects of quality improvement of labor and capital, business cycles and trade liberalization on the efficiency changes from 1981 to 2012 under the assumption of CRS(constant returns to scale) and VRS(various returns to scale). Important finding are as follows. Relative efficiency levels of life insurance industry are much higher than those of the non-life insurance industry. The Korean life and non-life insurance industry has experienced increasing trends of relative productivity levels, but the Korean non-life insurance industry has shown a higher level of efficiency increase. Moreover, the Korean life and non-life insurance industry exhibits counter-cyclical trends and showed increasing returns to scale after 2000s. Finally, the efficiency of the Korean life and non-life insurance industry has received very large impacts from capital quality improvement as well as from trade liberalization. The policy implication is that government policy should be made, based on the countercyclical trends of the Korean insurance industry.
