新三板挂牌企业融资偏好及融资效率研究

January 2019 (has links)
abstract: 本文选取当前在学界和业界关注度较高的“新三板”企业作为研究对象,从融资效率和融资偏好角度实证了新三板企业当前的运行状况,补充了资本结构和融资效率的研究文献。利用二元选择回归以及分位数回归方法,探究了内部融资、债务融资以及权益融资偏好的影响因素。本文发现:1)对于内部融资,企业资产负债率越低、经营能力越强、盈利能力越好、抵押品越少以及公司成长性高的企业更倾向于使用内部融资,资产负债率对内部融资的负面影响边际增大;2)对于债务融资,资产负债率越低、盈利能力越好、经营能力越强、抵押品越多、公司成长性高的企业更倾向于使用债务融资;3)对于权益融资,盈利能力较差、经营能力较弱的企业更倾向于使用权益融资,而资本结构以及公司成长性对权益融资没有影响。分位数回归也发现,盈利能力、现金状况、总资产周转率、资产流动性、非债务税盾、民营企业以及公司成长性等变量对权益融资的影响较为稳定,提示公司的特征变量对权益融资并没有明显的主导作用。在融资效率上,本文也发现:1)于2012年挂牌新三板的企业整体融资效率不高,DEA融资效率为有效的企业占比仅为10%左右;但融资效率在逐年持续改善,表现出一个较好的发展势头。并且,对于做市转让的企业来说,2014年由协议转让改为做市转让以后,融资相对有效的企业数量增长明显快于协议转让企业,表明采用做市转让的企业融资效率优于采用协议转让的企业。2)市场整体融资规模并未达到挂牌企业的需求,导致一半以上企业尚未达到最优的生产经营状态,仍需要资金来增加生产资料的投入,以扩大生产规模获取规模收益。对于做市转让的企业来说,在2014年由协议转让改为做市转让以后,规模报酬递增的企业数量占比下降更快,表明做市转让制度要比协议转让制度从融资效率角度更能满足新三板企业的融资需求。 / Dissertation/Thesis / Doctoral Dissertation Business Administration 2019

中國大陸財政地方分權對社會保障效率的影響 / The influence of fiscal decentralization on the efficiency of social security in China

原靖雯, Yuan, Ching Wen Unknown Date (has links)
The purpose of this study is to investigate the influence of fiscal decentralization on the efficiency of social security in China since the realization of social security was promoted and some relevant policies were implemented in 21 century. This study uses China’s provincial-level data of 31 regions from 2000 to 2009 and uses two inputs and three outputs to calculate the efficiency scores as the dependent variables. The inputs are the proportions of expenditures for social security and employment effort to total public expenditures and the proportions of hygiene, social security, and social welfare employed people to total employed people. The outputs are the coverage rate of urban basic pension insurance, the coverage rate of unemployment insurance, and the coverage rate of urban basic medical care insurance. Then, this study establishes four specifications of the Tobit model. Other factors, gross regional product per capita (PGRP), the degree of openness (OPEN), the scale of provincial government (SOG), the quadratic term of the former (SOGSQ), area dummy variables, and time dummy variables, are added into the Tobit model. The primary finding of this study is that fiscal decentralization has a positively non-monotonic influence on the efficiency of social security. This contributes positively to the efficiency of provincial government’s social security, but this positive influence does not always exist.

Efficiency in hospitals owned by the Iranian Social Security Organisation: measurement, determinants, and remedial actions.

Afzali, Hossein Haji Ali January 2007 (has links)
Given the need to ensure the best use of scarce resources, increasing emphasis is being placed on hospital efficiency measurement. In the literature about hospital efficiency measurement, there is an absence of a well-defined framework to select the most appropriate set of input and output variables. Variables used in hospital efficiency studies predominantly reflect a narrow view of hospital functions with a little attention to quality variables. This implies that the hospital goal and its full range of functions in efficiency measurement are poorly understood. While numerous studies have been undertaken in developed countries, there have been only a few attempts at measuring hospital efficiency in developing countries. However, there has so far been no systematic attempt, using frontier-based techniques, to measure the efficiency of Iranian hospitals, and to identify factors affecting efficiency and remedial actions to improve efficiency. By focusing on the above two issues, this thesis makes three arguments. First, by undertaking an in-depth investigation regarding the multi-product nature of hospitals, considering a fuller range of hospital functions, and the values of various stakeholders including patient, staff, and community, this study has proposed a health-oriented framework with a focus on the Iranian hospitals to select the most appropriate variables for measuring hospital efficiency. I argue that both variables (existing in the literature, and discussed for addition) should be taken into account in order to enhance the validity of hospital efficiency studies. Second, two types of techniques (simple ratio analysis and data envelopment analysis) were used for measuring the technical efficiency of hospitals owned by the Iranian Social Security Organization (SSO). The benefits and shortcomings of each method were discussed. For example, considering major surgery rates, which implicitly provide information about the case-mix, has revealed that all high-turnover, high-occupancy outlying hospitals as well as the majority of hospitals falling in the relatively well-performing quadrant in the Lasso diagram had a low major surgery rate. This suggests that simple ratio analysis can only measure the performance of hospitals over a single dimension ignoring their multi-input and multi-output nature of hospitals. Using Data Envelopment Analysis (DEA), I measured technical efficiency, scale efficiency, and types of returns to scale for the SSO hospitals. In addition to studying their overall and relative efficiency, I analysed the magnitude of the inefficiency for each individual hospital. The results revealed that 22 of the 53 hospitals were deemed to be efficient. Inefficient hospitals had an average score of 78%, implying a potential reduction in all inputs on average by about 22% with no impact on output levels. The comparison of DEA results and simple ratio analysis has revealed that hospitals with an exceptional performance on individual variable even though less valuable compared with other variables can gain a full efficiency score. This critical analysis of the study strongly suggests that the findings obtained from unconstrained DEA should be interpreted with caution. Finally, in addition to simply measuring efficiency, it was felt that a better understanding of the factors affecting hospital efficiency and remedial actions to improve efficiency is needed. Using qualitative methods, a complex mix of organisational factors such as hospital financing, political influences such as political pressures in determining hospital location, and the training and experience of the managers were argued to be influential factors in hospital efficiency. The interviews also provided a great insight into remedial actions such as reforms in the regulatory framework and corporatization. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1297532 / Thesis (Ph.D) -- University of Adelaide, School of Population Health and Clinical Practice, 2007

Novel pH Responsive Amphiphilic Diblock Copolymers with Reversible Micellization Properties

Palaniswamy, R., Dai, S., Tam, Michael K. C., Gan, L.H. 01 1900 (has links)
Di-block copolymer of poly[methacrylic acid-block-2-(diethylamino)ethyl methacrylate] [P(MAA-b-DEA)] with narrow molecular weight distribution was synthesized using the atom transfer radical polymerization (ATRP) technique. The micellization behavior of the P(MAA-b-DEA) copolymer in aqueous solution at room temperature and different pH values were examined by potentiometric and conductivity titration, UV-Visible spectrophotometry, ¹H-NMR, static and dynamic laser light scattering. At low pH (< 4.2), core-shell micelles were formed with MAA core and protonated DEA shell. At moderate pH values, the polymer precipitated from water and formed a cloudy solution, where the polymer chains aggregated into larger particles resembling that of a hard sphere induced by electrostatic interactions. At high pH (> 9.5), core-shell like micelles consisting of hydrophobic DEA core and ionized MAA shell were re-established. / Singapore-MIT Alliance (SMA)

Eficiència de les universitats públiques espanyoles. Una anàlisi quantitativa

Vilalta Ferrer, Montserrat 25 April 2008 (has links)
L'estudi inclou una anàlisi d'eficiència de les universitats del sistema públic espanyol usant la tècnica no paramètrica d'anàlisi de fronteres coneguda com a Data Envelopment Analysis (DEA). Mitjançant una tria d'inputs i outputs vinculats a la docència i a la recerca, s'obté una classificació de les universitats en eficients i no eficients, indicant per aquestes últimes el grau o nivell d'ineficiència. Usant una tècnica desenvolupada a partir del DEA, s'aborda l'estudi de les unitats eficients per tal de determinar-ne aquelles que presenten un comportament atípic i, per a la resta, obtenir-ne una ordenació segons els nivells del que es coneix com eficiència robusta o supereficiència. En una segona part, s'analitza la possible influència de variables o factors ambientals -inputs no controlables- sobre els resultats d'eficiència obtinguts, usant, per tal de comparar resultats, una tècnica paramètrica basada en una análisi de regressió, i una no paramètrica coneguda com a model de valors ajustats.

Operating Efficiency Evaluation Study of Faculties in Private University -A Case Study of Certain Medical University

Hsu, Fang-Yih 30 August 2010 (has links)
In recent years, domestic high education institutions encounter the difficulty of decrease in numbers of enrolling students and increase in number of schools, which is resulted from the trend of less newborn children and more loosing governmental policy by Ministry of Education. In such environments, the private schools encounter high pressure of seeking sufficient enrolling students and more competition among schools. Therefore, management of private schools should focus on increasing efficiency of operating organization so private schools can be developed with more competition in the future. How to operate and allocate available resources and to achieve educational goals become the most important topics for school management. Schools are Non-Profit Organization and this thesis is intended to evaluate the relative efficiency of faculties of colleges or universities with Data Envelopment Analysis¡]DEA¡^, which is popular methods for researches regarding Non-Profit Organization. It includes the CCR model and BCC model and selects 4 input items and 3 output items as evaluation indicators. The thesis employed the DEA model in the case study to evaluate the Overall Efficiency, Pure Technical Efficiency and Scale Efficiency of school faculties and performed slack variable analysis to inefficient faculties to obtain inefficiency reasons and provide further improvements. The case study in this thesis was performed with efficiency evaluation on 19 faculties of certain medical university based on the information of fiscal year of 2008. The results were as below: 1.Overall Efficiency: In the case study, 7 faculties are relatively inefficient, representing 37% of population. This means that over 1/3 of total population is inefficient. 2.Pure Technical Efficiency: In the case study, 3 faculties have no pure technical efficiency, representing 16% of population. The negative result is less than overall efficiency, which implies that the inefficiency may be caused by scale inefficiency. 3.Scale Efficiency: In the case study, 7 faculties have no scale efficiency, representing 37% of population. Such faculties need to adjust their scales to reach the overall efficiency. This thesis also provided the improvement suggestions for inefficient faculties and operation strategies for management.

Essays on Efficiency Analysis

Asava-Vallobh, Norabajra 2009 May 1900 (has links)
This dissertation consists of four essays which investigate efficiency analysis, especially when non-discretionary inputs exist. A new approach of the multi-stage Data Envelopment Analysis (DEA) for non-discretionary inputs, statistical inference discussions, and applications are provided. In the first essay, I propose a multi-stage DEA model to address the non-discretionary input issue, and provide a simulation analysis that illustrates the implementation and potential advantages of the new approach relative to the leading existing multi-stage models of non-discretionary inputs, such as Ruggiero's 1998 model and Fried, Lovell, Schmidt, and Yaisawarng's 2002 model. Furthermore, the simulation results also suggest that the constant returns to scale assumption seems to be preferred when observations have similar sizes, but variable returns to scale may be more appropriate when their scales are different. In the second essay, I make comments on Simar and Wilson work of 2007. My simulation evidence shows that traditional statistical inference does not underperform the bootstrap process proposed by Simar and Wilson. Moreover, my results also show that the truncated model recommended by Simar and Wilson does not outperform the tobit model in terms of statistical inference. Therefore, the traditional method, t-test, and the tobit model should continue to be considered applicable tools for a multi-stage DEA model with non-discretionary inputs, despite contrary claims by Simar and Wilson. The third essay raises an example of applying my new approach to data from Texas school districts. The results suggest that a lagged variable (e.g. students' performance in the previous year), a variable which has been used in the literature, may not play an important role in determining efficiency scores. This implies that one may not need access to panel data on individual scores to study school efficiency. My final essay applies a standard DEA model and the Malmquist productivity index to commercial banks in Thailand in order to compare their efficiency and productivity before and after Thailand?s Financial Sector Master Plan (FSMP) that was implemented in 2004.

Comparison and Analysis of The Performance Status of Foreign Affairs Police of Taiwan: by Data Envelopment Analysis (DEA)

Lee, Cheng-Ju 04 August 2008 (has links)
Due to the National Immigration Agency going public, a large amount of foreign affairs policeman shifts there forward from local police bureau, hence brings about the shortage of local foreign affairs policeman in use. However, limited by the language specialty, it seems impossible to make up such a deficiency in a short time. This study aims to take an overview of the aftermath of this systematical manpower change, focusing on the specific influence which caused from the shortage of local foreign affairs policeman, and on whether the performance of local foreign affairs police in each city and country is negatively impacted as well. This study analyses the current performance status of local foreign affairs police in 22 cities and countries by means of ¡§Data Envelopment Analysis¡¨ (DEA), which mainly evaluate the efficiency of seizing related breach and crime by local foreign affairs police, and then probe into reasons of such kind of inefficiency if any. In so doing, this study might provide strategic improvement suggestions for those which have bad achievement. Based on the data of 22 cities and counties in 96 fiscal year, this study adopts diverse research methods of DEA, such as CCR, BCC, Efficiency of Scale¡BRTS¡BSBM¡BFDH¡BMALMQUIST INDEX, and then tries to offer positive suggestions according to the study outcomes, so as to promote the performance of those targeted districts.
