지방공기업의 지배구조와 대리인비용

權藝卿(Quan Yiqing) 한국국제회계학회 2010 국제회계연구 Vol.0 No.33

지방자치단체의 재정을 투명하게 공시하고 책임성과 효율성을 제고하기 위해 복식부기/발생주의 회계제도를 실시하고 있다. 특히 지방자치단체가 일반회계 및 특별회계의 재원에 의한 일반적인 행정활동만으로 주민의 공공수요를 충족시키기 어렵고 비교적 기업성이 강한 교통. 병원, 주택, 수도 등의 사업은 어느 정도 수익자부담원칙에 따라 그 비용을 부담시킴으로써 지방자치단체의 역량을 강화하기 위해 각종 지방공단과 지방공사를 두고 있다. 이러한 각종 지방공단과 지방공사를 지방공기업이라 칭한다. 지방공기업의 효율성에 대한 정보는 지방정부나 일반시민들이 궁금해 하는 것 중의 하나이다. 이런 지방공기업의 효율성에 영향을 미치는 요소들 중의 하나가 지배구조이다. 본 연구는 지방공기업 129개 지방공기업을 대상으로 4개 회계연도(2006-2009)의 지방공기업 경영정보공개시스템 제공 데이터를 이용하여 지배구조가 대리인비용에 영향을 미치는지 검토 분석하였다. 첫째, 지방공기업의 총임원수가 많을수록 상대적으로 자산회전율이 높고 대리인비용이 낮이지는 경향이 있다. 둘째, 지방공기업에서 비상임임원의 비율이 높을수록 자산회전율이 높고 이에 띠라 대리인비용이 낮아지는 결과를 보인다. 셋째, 지방공기업에서 경영자 성과급이 많은 지방공기업일수록 대리인비용(영업외비용 비율)이 상대적으로 낮아지는 경향이 있다. 넷째, 지방공기업에서 외부감사 수감횟수가 많을수록 상대적으로 자산회전율이 높고 대리인비용이 낮이지는 경향이 있다. 따라서 지방공기업의 효율성을 제고하기 위해서는 비상임임원의 비율을 높이거나 외부감사를 정기적으로 실시하여 내외부적 감시체제를 구축할 필요가 있어 보인다. 그리고 경영자의 성과급제도가 성공적이라 평가할 수 있다.

상하이 상장회사의 소유구조 및 이익관리와 대리인비용 간의 관계

Quan,Yiqing(권예경),Li-Rong,Zheng(정력용) 한국국제회계학회 2011 국제회계연구 Vol.0 No.37

본 연구는 중국기업의 소유구조, 이익관리와 대리인비용 간의 관계를 규명하고자 하였다. 본 연구에서는 중국 상하이 증권거래소에 상장되어 있는 기업들 중에서 상장 폐지, 금융보험업, ST(Special Treatment)기업, 재무자료 결측치 기업 및 극단치를 보이는 기업들을 제외한 675개를 연구대상으로 하고 2008회계연도 데이터를 사용한다. 기업소유구조와 관련된 기타자료 및 재무자료는 북경 SinoFin 정보 서비스 유한회사가 제공한 CCER 데이터베이스를 이용하였다. 본 연구결과는 중국 상하이 증권시장의 상장회사들에서 대리인비용은 소유권의 집중 정도가 높아질수록 판매 및 관리비 비율이 낮아지고 자산회전율이 높아지는 것으로 나타나 소유권의 집중정도가 높은 기업의 경우 대주주가(특히 1대주주) 경영자에 대한 감시·감독 역할이 대리인비용을 통제할 수 있음을 보여주고 있다. 또, 소유권의 견제정도가 높은 기업일수록 기업의 대리인비용은 상대적으로 높다는 연구결과를 얻었다. 이러한 현상은 선행연구들의 결과와 마찬가지로 대주주가 몇 명 있는 경우에서 기업경영에 대한 책임을 지는 주주가 분명하지 않기 때문에 대주주들의 무임승차문제가 발생하고 있음을 의미한다. 일반적으로 이익관리를 많이 하는 기업일수록 영업외 비용비율이 높아 지지만 소유권의 견제정도가 높은 기업일수록 이익관리의 상호작용을 통하여 그 비율이 더욱더 증가됨을 알 수 있다. 그리고 중국의 상장회사들에서 이루어지고 있는 이익 관리가 효율적인 이익관리가 아니고 기회주의적인 이익관리라는 증거를 얻었다. 즉, 중국 상장회사들의 경영자는 자신의 이익을 극대화하기 위한 이기적인 목적으로 이익조정을 하고 있다고 보아야 할 것이다. This study is focused on the effects of ownership structure, earnings management on the agency costs in Chinese listed companies. The processes of this empirical study are establishment of research hypotheses, elaboration of test model, definition and measurement of 675 sample companies, empirical analysis and interpretation of results. The data used in this research are provided from SSEportal and SinoFin information service co. in China. The proxies of ownership structure are ownership concentration, outside blocck-holders and proxies of earnings management is absolute discretionary accruals of modified Jones, model. the proxies of agency costs are firm size, ratio of sale and management expenses per operating revenues, ratio of operating revenues per total assets, ratio of operating revenues per other operating expenses, control variables are ratio of current liabilities/total assets, ratio of net cash inflow per total liabilities, industry dummy variable. The results of this study are as followings. First, the ownership concentrated companies tried to reduce agency cost actively rather than decentralized companies in China. Second, the interaction between ownership concentration and earnings management take negative effects on agency cost. Therefore we can say that the listed companies on Shanghai Stock Exchange implemented earnings management opportunistically.

Computational mathematical modeling of the nonlinear vibration characteristics of AFG truncated conical nano pipe based on the nonlocal strain gradient theory

Ruihua Zhang,Yiqing Cao 국제구조공학회 2022 Steel and Composite Structures, An International J Vol.42 No.5

In the present paper, the numerical dynamic analysis of a functionally graded nano-scale nonuniform tube was investigated according to the high-order beam theory coupled with the nonlocal gradient strain theory. The supposed crosssection is changed along the pipe length, and the material distribution, which combines both metal and ceramics, is smoothly changed in the pipe length direction, which is called axially functionally graded (AFG) pipe. Moreover, the porosity voids are dispersed in the cross-section and the radial pattern that the existence of both material distribution along the tube length and porosity voids make a two-dimensional functionally graded (2D-FG) truncated conical pipe. On the basis of the Hamilton principle, the governing equations and the associated boundary conditions equations are derived, and then a numerical approach is applied to solve the obtained equations.

The interface and its role in carrier transfer/recombination dynamics for the planar perovskite solar cells prepared under fully open air conditions

Fei Wang,Yiqing Chen,Guotao Han,Qianlong Zhang,Qilin Ma 한국물리학회 2016 Current Applied Physics Vol.16 No.10

The planar heterojunction perovskite solar cells, where the perovskite film is deposited directly onto a flat hole blocking layer, have recently attracted a great deal of attention owing to their high performance and ease of processing. However, the interface and its underlying role in carrier transport/recombination kinetics for such perovskite devices prepared under ambient air is still obscure. Herein, we addressed this issue by a dynamic intensity modulated photovoltage spectroscopy (IMVS) model using a continuity equation. The interface and its role in charge-carrier transport/recombination kinetics have been explored and discussed as an approach to understand the origin of the photovoltaic properties for the devices prepared under ambient air. The experimental IMVS responses were measured and satisfactorily fitted to the analytical results. Compared to the typical IMVS model based on dye-sensitized solar cells (DSSCs), the better IMVS fitting results presented in this study indicated that there was a discrepancy between the planar perovskite devices and those of DSSCs in electron transport/recombination properties, because carrier transfer across the TiO2/liquid electrolyte interface in DSSCs has been modified. That is, the Schottky interface in DSSCs needs to be replaced by the semiconductor heterojunction interface in perovskite solar cells (PSCs). Besides, the interface exhibits a more significant role in determining the carrier transport/recombination process by influencing the boundary conditions in a continuity equation. Furthermore, the intensity modulated photocurrent/photovoltage spectroscopy responses demonstrated that the carrier recombination characteristic is ultimately related with the surface and defect density in the interface. Interfacial modification, such as air-annealing, resulting in crystallographic changes, oxygen passivation, and variation in grain domain size, could suppress carrier recombination and prolong charge lifetime, which can yield more photo-generated electrons to be collected by anode, subsequently resulting in strikingly improving photovoltaic performance of the devices. In short, the dynamic IMVS model would help in elucidating the role of interface and the importance of interfacial modification or even interface design in order to obtain a highly efficient solar cell. The study can not only pave the way to construct the currentvoltage curve using a continuity equation model, but also provide new insights into the performance-improving steps for the PSCs prepared under fully open air conditions, which is of great importance for their future commercialization.

Intra Mode Decision for Reducing Block Types and Prediction Modes Based on Edge Information in H.264/AVC

Zhewen ZHENG,Yiqing HUANG,Qin LIU,Takeshi IKENAGA 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7

H.264/AVC performs rate-distortion optimization (RDO) in order to select the best coding modes with best coding efficiency. However, computation complexity is also increased. In this paper, a fast intra mode decision algorithm is proposed. With both the magnitude and the orientation of the local edge information, most proper block mode is selected from 4×4, 8×8 and 16×16 block modes. Then by the edge information obtained from previous step, candidate prediction modes are decided for the chosen block modes. The number of modes investigated in RDO can be reduced to 36 or 48 in common case instead of 736 in full search. Simulation results show that the proposed algorithm saves about 75% coding time with negligible PSNR loss and bit-rate increase compared with full search.
