bert模型文献综述
bert模型文献综述BERT模型文献综述引言自然语言处理（Natural Language Processing，NLP）是人工智能领域的重要研究方向之一，其目标是使计算机能够理解和处理人类语言。
近年来，随着深度学习的快速发展，基于神经网络的模型在NLP任务上取得了显著的成果。
BERT（Bidirectional Encoder Representations from Transformers）模型作为一种预训练语言模型，通过学习大规模文本数据的上下文相关表示，取得了许多重要的突破。
BERT模型原理BERT模型是由Google在2018年提出的，并在NLP领域引起了广泛关注。
该模型的核心思想是利用Transformer架构进行预训练，通过双向上下文表示来捕捉词汇的丰富语义信息。
BERT模型包含多层Transformer编码器，其中每一层都由多头自注意力机制和前馈神经网络组成。
通过预训练阶段的大规模数据学习，BERT模型能够产生丰富的上下文语义表示，从而在下游任务中取得优秀的效果。
BERT模型的预训练任务BERT模型通过两个预训练任务来学习上下文相关的表示。
第一个任务是“Masked Language Model”（MLM），即将输入文本中部分词汇进行遮盖，然后通过模型预测被遮盖的词汇。
这个任务可以使模型学习到上下文信息和词汇之间的关系。
第二个任务是“Next Sentence Prediction”（NSP），即判断两个句子在原文中是否是相邻的。
通过这个任务，BERT模型能够学习到句子之间的语义关系。
BERT模型的应用BERT模型在众多NLP任务上都取得了显著的性能提升。
其中，包括文本分类、命名实体识别、问答系统、语义相似度计算等。
BERT 模型通过在这些任务上进行微调，能够将上下文语义信息应用到具体的任务中，从而提升模型的性能。
此外，BERT模型还被广泛应用于机器翻译、文本生成和信息检索等领域。
希金斯可持续增长模型英文文献
希金斯可持续增长模型英文文献Higgins's Sustainable Growth Model.Higgins's Sustainable Growth Model is a theoretical framework that aims to explain the relationship between economic growth and environmental sustainability. The model posits that economic growth is not inherently sustainable, and that it can only be sustained if it is accompanied by environmental protection and conservation measures.The model is based on the following assumptions:Economic growth is driven by the consumption of resources.Resources are finite.Environmental degradation is a negative externality of economic growth.The model suggests that if economic growth is not accompanied by environmental protection and conservation measures, it will eventually lead to environmental degradation. This degradation will, in turn, negatively impact economic growth, as it will reduce the availability of resources and increase the costs of production.The Higgins's Sustainable Growth Model has been used to inform a variety of policy decisions, including the development of environmental regulations and the promotion of sustainable economic practices.Chinese Answer.希金斯可持续增长模型。

关于国内外财务风险预警模型的文献综述
财务与审计矣扌图內外财务风险额警檬塑询丈献探述□昆明李秀雷企业为了及时有效地识别和防范财务风险隐患，实现了持续健康发展的目标，建立财务风险预警模型。
然而，现有的财务风险预警模型往往效率低下，存在缺陷。
首先分析了国内外财务风险预警模型，其次分析了模型的局限性，最后对研究财务风险预警模型提出了合理化建议。
一、国外财务风险预警模型研究综述1.国外财务风险研究现状。
国外学者通常通过财务危机定义财务风险。
Beave需有这种看法：如果一家公司面临破产，或者存在未支付优先股息和无法偿还债务的现象，那么它可以被视为面临财务危机。
Ross等人指出了破产的四个内涵：技术、企业、会计、法律破产。
并认为从危机预防的角度来看，财务危机是指技术破产。
C.VanHome等财务风险的定义更为广泛，而财务风险由两个组成部分，即使用财务杠杆引发每股收益变动和失去偿付能力的风险。
2.财务风险预警模型研究现状。
①单变量判别模型。
Fitzpatrick是最早探索财务风险预警模型的学者之-O他以19家公司为样本，他建立一个单变量判别模型来探索财务风险预警问题，通过对破产和经营正常企业财务比率的对比分析，得出产权比率和净资产收益率两个指标对财务风险具有较高的预警精度。
芝加哥大学教授BeaverJF发了一个基于F i tzpatrick的单变量预警模型，以1954-1966年158家破产企业与正常企业的财务关系为研究对象，得出净利润/总资产指标和净现金流量/总负债指标在财务风险预测方面更为准确。
②多变量判别模型。
Altman是将多变量判别模型应用于财务风险预警领域研究的首位开拓者。
他提出的Z-Score模型是国外影响最大的多元线性判别模型。
从1946年至1965年期间66家有问题和经营中的公司中随机抽取一个样本，它从22个提供最佳预警的备选财务比率的范围内选择了5个，并建立了一个五变量判别模型来计算Z值，并根据Z值的大小确定公司破产或失败的概率。

文献引用模型
文献引用模型
文献引用模型是一个用于描述和分析文献之间引用关系的数学模型。
这种模型在学术研究领域、图书馆科学、信息科学和计算机科学等领域中都有广泛的应用。
文献引用模型主要用于分析学术文献的引用网络，揭示文献之间的关联性和影响力，以及学术领域的研究趋势和热点。
一个常见的文献引用模型是基于图的模型，其中文献被表示为图中的节点，而引用关系被表示为节点之间的边。
这种图模型可以是有向的（表示引用方向），也可以是无向的（不表示引用方向）。
通过分析这个图模型，可以计算出各种指标，如文献的入度（被引用的次数）、出度（引用的次数）、影响因子（被引用次数与总引用次数的比值）等，从而评估文献的影响力和学术价值。
除了基于图的模型外，还有一些其他的文献引用模型，如基于概率的模型、基于矩阵的模型等。
这些模型各有特点，适用于不同的应用场景和分析需求。
需要注意的是，文献引用模型虽然可以为我们提供很多有价值的信息，但也有一些局限性。
例如，引用关系可能受到多种因素的影响，如作者的偏好、期刊的引用要求等，因此并不能完全反映文献的实际学术价值。
此外，文献引用模型也面临着数据稀疏性、噪声等问题。
因此，在应用文献引用模型时，需要综合考虑其优缺点，并结合其他方法和数据来进行综合分析。

Research on Competency Model:A Literature Review andEmpirical StudiesAbstractWestern countries have applied competency models to addressing problems existed in their administrative and managerial systems since 1970s，and the findings is positine and promising. However, competency model hasn’t been introduced to China until 1990s and it is still unknown and mysterious to many Chinese managers. This paper aims to uncover the mysterious veil of competency model in order to broaden the horizon of Chinese managers and boost China's human resource development as well as management.Keywords:Competency，Competency Models，Empirical Studies of Competency ModelsIt has been more than 30 years since competency model was utilized to human resource management.In western countries，competency model first displayed its effectiveness in government administration, meanwhile many multinationals and their branch companies applied the competency model to their daily business management and their business was a great success. As the notion of competency is gradually come to light and accepted by people all around the world，more and more enterprises have been trying to build their own competency model under the help of professional consultant firms. As a result，competency model has gradually been a very fashionable phrase in the field of management and quite a few enterprises are thus benefited from it. In recent years, competency model has become a hot spot in the Chinese academia as well as big-，middle- and small-sized enterprises alike，many relevant writings and books have also been translated and published. However, competency and competency model are still mysterious to many Chinese scholars, business managers as well as government administrators.Purpose and Significance of the StudyThe purpose of the study aims to make a critical literature review of the competency model，clarify some confusion related to it and explore its application. The following questions are employed to guide this study:What is competency? What is competency model? What are the theoretical and empirical findings related to competency model?The study illustrates how we could take advantage of competency model in our harmonious society building. On one hand，the study will delineate competency and competency model in order to clarify confusions related to it since it is still strange and mysterious to many Chinese managers and administrators;on the other hand，thestudy would enrich Chinese HRD&HRM in the field of government administration and business management both theoretically and empirically.Research MethodThe present study has utilized qualitative analysis, induction and deduction. Since this research is a literature review in some sense, qualitative analysis will be an indispensable research method; Induction and deduction are applied to both theoretical and empirical studies.In order to enhance the credibility of present research，only the authoritative publications on competency model are reviewed，including books and papers written by foreign and Chinese scholars and HRDHRM practitioners. By searching for the keywords "competency" "competency model" and "competency model building" as well as "empirical studies on competency models"，books and papers written by well-known foreign scholars such as McClelland D. C.，Lyle M. Spencer, Anntoinette D. Lucia, Richard Lepsinger etc.，are available; by the same token，books and papers written by Chinese scholars such as Zhi-gong He，Jianfeng Peng, Shaohua Fang, Nengquan Wu，etc.，could be consulted. All the books and papers are published between 1950s and 2007. In addition, many data cited in this paper comes from empirical studies at home and abroad.FindingsIn this part，a literature review of competency is firstly carried out;then competency model as well as its evolution，development and innovation is delineated;finally empirical studies are reviewed. Empirical studies mainly focus on competency model building and its application to human resource development and management.Understanding CompetencyIn 1973，American scholar David C. McClelland published his paper Testing for Competency Rather Than Intelligence which cited a large amount of research findings to illustratethe inappropriateness of assessing personnel qualities by abusing intelligence tests. Dr. McClelland further explained that some factors (personality, intelligence, value，etc.)which people had always taken for granted in determining work performance hadn't displayed their desired result. As a result，he emphasized that people should ignore those theoretical by pothese and subjective judgements which had been proved groundless in reality. He declared that people should tap directly those factors and behaviors which could really impact their performance (McClelland, 1973). These factors and behaviors were named "competency" by McClelland. The publishing of this paper symbolized the debut of competency research. From then on，many scholars started getting involved into the research on competency and they conceptualizedcompetency from different perspectives as shown in the following table: The above ten concepts of competency have a lot in common:①Competency is motive, trait，value，skill，self-image, social role，knowledge;②Competency is a combination;③Competency should be measurable, observable, instructional，phasic and hierarchical;④Competency is a determinant to outstanding performance.Thus competency is an underlying combination of individual characteristics such as motive, inner drive force, quality, attitude，sole role，self-image, knowledge and skill，it is causally related to criterion-referenced effective and/or superior performance in a job or situation and it is measurable，observable and instructional.Besides，many scholars and consultancy firms believe that competency could be explained under the help of three different models:Iceberg Model. This model treats competency as an iceberg, the part above the water represents behavior, knowledge and skills which are easy to measure and observe，while the part under the water symbolizes underlying qualities such as value，attitude，social role, self-image，traits which are hard to assess，and the deepest part under the water represents the most latent qualities such as inner drive force，social motive, etc. which are most difficult to observe and measure.Onion Model. This model treats competency as an onion, the outer layer represents skills and knowledge which are liable to acquire，the inner layer refers to qualities such as self-image，social role，attitude and value which are relatively difficult to appraise, while the core of the onion symbolizes traits and motives which are most difficult to cultivate and develop.Brain Model. This model stems from the brain mechanism. It presupposes that the brain could be divided into four parts. Each part functions differently. The upper-left part is in charge of competency such as analysing capacity, calculation, strong logic ability; the upper-right part is in charge of competency such as innovation and intuition;the bottom left part is in charge of competency such as organizing ability, planning ability; and the bottom-right part is in charge of competency such as communication ability，perception, etc. Different parts will exert corresponding influence on competency development.Conceptualizations of Competency ModelFew foreign scholars have directly put forward conceptualizations of competency model. By contrast，many Chinese scholars have expressed their opinions on it. The present paper only cites those concepts that have been published by authoritative publishing houses.Jianfeng Peng, a professor in Ch;na Renmin University，together with his students, has studied how to build competency models for effective HR management since 2003. He thought competency model was the combination of differentqualities which were necessary for people to successfully finish a job or achieve superior performance，these qualities included different motives，traits, self-images and social roles as well as knowledge and skill (Jianfeng Peng, 2003). Prof. Peng believed that a competency model was composed of 4-6 competencies that were closely related to performance. Competency models could help managers judge and distinguish key factors that led to superior performance or underperformance. As a result，competency model could be treated as a foundation to improve performance.Professor Nengquan Wu from Sun Yat-sen University published his book Competency Model:Design and Application in 2005，according to his understanding, competency model refers to "proficiencies that people define core competencies of different levels, delineate corresponding behaviors，determine key competencies as well as f inish certain work.”(Nengquan Wu，2005). Prof. Wu conceptualized competency model from the perspective of methodology. He believed that competency model was a unique HRM thinking mode, method and operation flow. On the basis of organizational strategy, competency model could be utilized to enhance organizational competitiveness and improve performance.Shaohua Fang, a senior HRM consultant and expert，provided us with the following definition:"Competency model is to conceptualize and describe the necessary knowledge,skills，qualities and abilities which an employee should have in order to finish work (Shaohua Fang, 2007)”.By taking advantage of definitions of different levels and related behavioral descriptions, people could determine the combination of core competencies and required proficiency to finish work. Hc} pointed out these behaviors and skills must be able to measure，observe and instruct and they should exert a great influence upon personal performance and business success.International Human Resource Institute(IHRI) has also defined competency model:"The so-called competency model is the standardized description and explanation of competencies that could actualize superior performance.”(·IHRI, 2005)IHRI declared that a competency model should include 6^-1 2 competencies.In summary, the first concept mentioned above attaches an importance to the composition of competency model and its function, while all of the rest three concepts emphasize cognitive abilities as well as criterion-referred performance. Thus competency, model is a combination of different competencies which could be observed，delineated，explained and calculated on one hand，and could facilitate superior performance on the other hand.Development and Evolution of Competency ModelIn early 1970, top officials in U. S. Department of State believed that theirdiplomats' se- lection based on intelligence test was ineffective. It was an upset situation for them to find that many seemly excellent people fail to live up to their expectations regarding their work performance. Under such circumstances, Dr. McClelland was invited to help Department of State design an effective personnel selection system which could appraise the actual performance of employees. In that program，McClelland and his colleague Charles Dailey adopted the method of Behavioral Event Interview (BEI) to collect information in older to study factors that influenced the diplomats' performance. Through a series of summaries and analyses, McClelland and Dailey found out the differences between an excellent diplomat and a mediocre diplomat as far as their behaviors and modes of thinking were concerned. In this way, competencies that a diplomat should possess were found out. This program is the earliest empirical application of competency model. And the research findings were two papers: Improving Officer Selection for the Foreign Service (McClelland&Dailey，1972) as well as Evaluating New Methods of Measuring the Qualities Needed in Superior Foreign Service Information Officers(McClelland& Dailey，1973).Mcber and American Management Association (A'MA) also started their research on competency model in the same year. They focused on providing the answer to the question:what kind of competencies should be displayed by successful managers rather than unsuccessful ones? AMA spent 5 years observing 1 800 managers. By comparing the performance of excellent managers and mediocre ones, AMA defined their competencies based on their traits. The research results showed that all the successful managers shared the following 5 competencies:professional knowledge，maturity of mentality, maturity of .entrepreneurship，people relations and maturity of the profession. Of which，only professional knowledge were shared by excellent and mediocre managers (Mcber&.AMA, 1970).Then Prof. Bray carried out 8 years research at AT&T based on technique of assessment center. From the aspectives of abilities, attitudes and traits, etc.，he built a competency model composed of 25 competencies such as interpersonal relations, expression ability, social sensitivity, creativity，flexibility，organizational ability，planning ability, decision-making ability, etc(Bray and Grant，1978).In China，however, researches on competency model are relatively much late.Chinese scholars Chongming Wang and Minke Chen published their paper about competency model in Psychological Science in 1992. They studied 220 senior and middle-level managers of 51 enterprises in 5 cities. After examining and testing the competency model for senior managers on the basis of factor analysis and structural equation modelling, they compiled "Key Managerial Behavior Assessment Scale" (Chongming Wang&Minke Chen，2002).Scholars such as Kan Shi, Jicheng Wang and Chaoping Li took advantage of Behaviocal Event Interview to assess the competency model for senior managers in the industry of telecommunication (Kan Shi，Jicheng Wang&Chaoping Li，2002). Jicheng Wang designed 5 universal competency models for technical personnel，sales people, community service personnel，managers as well as entrepreneurs respectively.Jianfeng Peng and his postgraduate student Xiaojuan Xing built 4 universal competency models for business managers，business technical personnel，marketing personnel as well as HR managers (Jianfeng Peng，2003 ).The above domestic studies illustrate that competency models for middle-level and senior managers have been built based on in-depth interview and questionnairing. Most publications only focus on conceptualizing competency model，its development，behavioral event interview as well as competency model building，most of the findings are theoretical rather than empirical. By contrast，foreign studies are much maturer both theoretically and empirically.Empirical StudiesEmpirical studies highlight the application of competency model to enterprises, governments and other institutions.Nowadays，empirical studies on competency models mainly focus on the following 4 aspects:Staffing and Selection. Besides job standards and skills prescription, more and more businesses have carried out their personnel staffing and selection in light of the candidates' competencies which are crucial to their future performance. This competency-based personnel staffing and selection has connected business strategies and targets to business employees themselves. As a result，the quality of staffing and selection is greatly improved.Performance Management. Businesses which have built their competency models are more interested in the competency rather than the result itself in their performance management. As a result, their performance management style has been competency-driven rather than result-driven. Managers haven’t attached an importance to short-term performance, but current and long-term performances. In such a managerial system，outstanding performance has been easily actualized. Each employee has made most of their core competencies and expertise to make a contribution to their business.Compensation Management.After the competency-based compensation management system is set up, businesses have concentrated on their employees’future development and potential value, which has stimulated employees and managers of all ranks to improve themselves both menetuacy and teconologcal. Competency oases compense lion management system has helped enterprises attract and retain moretalents. In a word，competency model has endowed employees with a sense of respect and creativity.Training and Development. Enterprises which have built their competency models tend to determine core competencies in light of business strategies，environments, employee development planning and performance appraisal. Enterprises decide their training and development priorities on the basis of competency model.Future TrendsDespite that there is a growing body of literature on competency model，research on competency model is still in a premature stage and many questions still remain unanswered. Therefore, further research is required to address several important issues.First of all，although there are growing studies on the impacts of the competency model on organizational outcomes，antecedents of competency model need to be identified and academically explored. Future studies are needed to examine the relationships between the features of competency model and its key antecedent variables such as organizational sttracture.leadership and external environment. For example，it can be reasoned that the features of competency model are likely to be positively correlated with the structures of enterprises, governments as well as other institutions. Secondly，the impact of competency model on performance needs to be thoroughly explored. More studies are needed to examine whether the features of competency model or organizational culture，has direct or indirect impacts on organizational performance. While quite a few HRD and HRM researchers and practitioners have demonstrated that the concept of competency model has a positive impact on organizational performance, however，such impact may be mediated by other important organizational variables. Finally, it is also important to consider the relationships of competency model and other important HR variables such as career development, managerial coaching as well as employee training.Conclusions and DiscussionsIn conclusion，competency model has increasingly exerted profound influence on human resource development and management. While this concept has received an increase in both academic and management fields，there are increasing empirical studies designed to examine the nature of the construct and its relationships with other important organizational variables. More studies are needed to enhance the theoretical and empirical foundations of competency model.胜任力模型研究：文献综述和实证研究摘要20世纪70年代以来，西方国家已经利用胜任力模型来解决存在于行政和管理系统中的问题，其结果是积极且有前途的。

基本介绍
本文主要研究债券市场因子中期限因子TERM（利率有关）、违约风险DEF（公司债 券）和 股票市场因子中 企业规模（ME）、账面市值比（BE/ME）共五个因子对于 债券收益与股票收益的解释作用 在Fama和French研究基础上做三点扩展 研究对象从普通股扩展到美国政府债券，公司债券和股票 扩展了解释收益的变量，增加了债券期限因子 测量资产定价模型方法采用时间序列回归而不是横截面回归
基于E/P的投资组合
模型结果解释
表2显示三个股票市场因子与两个期限因子对股票和债券收益的解释作用； 25个股票组合在市场收益（RMO）上产生斜率接近于1，可以把平均RMO收益解释成股 票市场风险溢价； 对于股票来说，TERM和DEF的收益斜率（表8）在0.8左右， TERM和DEF的月均值分别为 0.06%、0.02%，无法解释股票的平均额外收益； BE/ME与相对盈利有关： 低BE/ME对应于高收益，： 高BE/ME对应于低收益 除了低等级公司， TERM和DEF决定了债券收益的公共方差（表8）； 五因子回归（表8）中得到，RMO，RERM和DEF对于股票收益的作用在很大程度上由额 外收益RM-RF（表7）决定的； 五因子能很好解释债券和股票收益的一般变化和平均横截面收益 详见P286
分离样本测试
目的：检验企业规模和账面市值比是否能够决定平均股票收益 方法：把25个企业规模-BE/ME组合分成两个对等的组。一组用于附属加权组合收益 的建模、另一种用于一般样本的三因子建模；然后对调数据，做相同研究得两组回 归，则每组中解释和附属收益来相互独立的股票之中的 回归结果见表10，P280 结果分析：两组25个企业规模-BE/ME组合的额外收益的回归在RM-RF，SMB，HML 上与全样本的结果一致；三因子斜率与表6相近，其截距与表9中全样本回归一致； 总之说明与企业规模和BE/M相关的收益中存在风险因子，企业规模和账面市值比能 够决定平均股票收益
时序回归结果分析二
解释收益 收益一般风险因子的平均风险溢价即为解释变量的平均值 超额市场收益RM-RF的月均值为0.43%，年均值一般5%，比较大；SMB平均收益仅 为 0.27%；SMB的斜率均超过1.7；HLM产生的风险溢价为0.40%每月，很大 期限结构因子的平均风险溢价与股票市场因素似乎无关。期限因子和违约风险因子 的月均值分别为0.06%、0.02%。期限因子和违约风险因子的低均值和高波动性有利 于解释债券收益。但解释股票平均收益中横截面显著变化的任务在股票市场因子上
债券平均横截面收益
表3、表7b和表8b表明债券收益中的一般变化主要是债券市场因子TERM和DEF引起 的。正如TERM和DEF值平均值，债券组合的平均超额收益接近0（见表2），因此时 序回归中截距接近0（见表9b），与预期一致 TERM和DEF的低平均溢价并不意味着期限结构因子在资产定价模型中是不适用的
时序回归结果分析二
不同组合收益情况的回归分析结果见表2，P258 投资组合中的平均收益就是一般风险因子的风险溢价（即回归的斜率） 因变量：
股票组合：每月超额收益在0.32%-1.05%之间；公司规模和平均收益呈负相关，账
面市值比与平均收益之间强烈正相关；平均收益随着BE的值由低到高逐渐递增； 债券组合：政府和公司债券组合的平均超额收益作用不突出，月平均超额收益未超 过0.15%，并且只有一个超过1.5个标准差。但表2中看不出：政府证券的平均收益随 着期限的增长而增长、长期公司债券比政府债券的平均收益要高、公司债券的平均 收益比低级债券高
检验股票市场因子的检验（三个步骤）
步骤一：用超额市场收益RM-RF来解释债券市场和股票市场的超额收益，回归结果 见表4 P263
检测收益的共同变化
检测收益的共同变化
使用联合因子解释收益，五因子：在表6基础上引入期限因子TERM、违约风险DEF 因子 回归结果见表7a和7b，P268-P269 结果分析：似乎否定了之前得出的债券收益与股票收益的随机过程是有重叠部分的 结论；对于股票而言，将TEAM和DEF引入对股票市场因子的斜率几乎无影响，对债 券而言同样如此；消减了在表3中二因子回归TEAM和DEF的大斜率；在表6中的债券 收益对于股票市场因子的反应，在表7b中不再看到；只有低级债券LG继续对股票市 场因子产生很大的斜率；股票收益由三个股票市场因子所影响，而股票收益与债券 收益之间的联系很大一部分来自两个期限结构因子。详见P269-P270
检测收益的共同变化
横截面的平均收益
股票平均横截面收益
RM-BF单因子模型：与第一稿相同，市场回归系数值无法体现与公司规模和账面市 值比相关的股票平均收益的横截面变化 SMB和HML二因子模型中，公司规模和账面市值比能解释股票平均收益的大部分变 化，但不能解释股票收益较之于上个月票据利率的平均溢价 RM-BF、 SMB和HML三因子模型中，解释股票平均横截面收益时作用很好 在三因子模型中加入TERM和DEF，对原截距几乎没有影响
模型的应用
原则上，模型应用方面包括：选择组合，估值组合，在案例研究中测试非正常收益， 测试资产成本 五因子模型的选择，如评估一个组合的绩效 三因子模型的选择，如测试影响平均股票横截面收益的约束； 单因子Sharpe-Lintner模型：仍旧被用来评估投资组合的业绩和估计资产的成本， 需要突破传统模式
检测收益的共同变化
分别检验债券市场因子和股票市场因子的解释力，目的是测试股票收益与债券收益 之间的随机过程是否存在重叠部分 债券市场因子的检验，引入回归变量期限因子TERM、违约风险因子DEF，检验结果 见表3，P261 结果分析：期限因子TERM、违约风险因子DEF决定了股票和债券收益的一般变化； 期限因子和违约风险因子对于股票收益变化的作用大于债券的；由违约风险引起的 收益的变化，小公司股票比大公司股票更为敏感；与Fama-Macbeth的归回结果不 同，DEF值不能解释股票平均收益中公司规模的作用，DEF月均值仅为0.02%等
时间序列回归
解释变量：股票市场组合的收益、企业规模、账面市值比、期限结构因子。 分类：债券市场因子：期限因子TERM（利率有关）、违约风险DEF（公司债券） 股票市场因子: 企业规模（ME）、账面市值比（BE/ME） 被解释变量（收益）
债券：两类政府债券以及五类公司债券的超额收益
股票：按企业规模和账面市值比形成的25个资产组合的超额收益 构造资产组合及指标选取 企业规模ME：S和B两类；SMB即账面市值比相同时不同公司规模下的收益之差
