【摘要】 近年来，企业融资难问题一直是阻碍我国经济发展的主要因素之一，政府出台很多政策和措施去解决这一难题，然而实际效用还有待提高。造成企业融资难的主要原因就是融资资质不足，融资风险难以度量，融资后因其违约成本较低导致违约风险较高，对其监管较难。依托供应链金融业务的供应链融资为解决企业融资难提供可能。供应链金融业务使资金流和货物流在供应链内产生局部闭合性，尤其是中小企业处于供应链的上下游重要环节上，与供应链核心企业之间形成紧密的伴生关系，核心企业的良好经营状况和信用资质，能通过供应链金融的整体性有效地传导给企业。在供应链融资中，企业融资后发生违约的可能较低，因为银行通过对供应链上物权和账款的监管，可直接了解融资企业的经营动态，有效防范和规避企业供应链融资违约。对银行来说供应链融资风险管理主要在企业供应链融资前的风险评估阶段，客观准确的风险度量可使银行有效规避企业供应链融资违约的发生。因此，在满足企业融资需求的同时，结合供应链融资的实际业务特点，为银行提供有一种全新的供应链融资风险度量方法和风险监控体系成为理论研究亟需解决的实际问题。目前国内的研究主要集中于供应链融资的运营模式、管理方式和风险种类的相关理论研究，对基于供应链金融的企业供应链融资中所蕴含的风险度量问题关注较少。在融资风险管理中较多运用定性分析方法，综述性的分析风险的种类、特性的文献较多，缺少直观的评估风险方式和量化模型；在供应链融资风险度量方面，主要以融资企业的角度出发，度量单一企业的融资违约风险，较少以银行等金融机构的角度评估供应链融资整体的风险性，整体性是供应链融资的最大特点。因此，论文以供应链的整体性为基点建立企业供应链融资风险度量模型，为银行构建供应链融资风险预警系统和风险监控体系是其研究的主要结论。论文各章的概况如下：第一章阐明选题的概况，包括：研究的背景、研究的目的和意义、研究的现状、研究内容和创新点等。第二章对企业供应链融资风险的理论基础进行梳理，为研究的主体部分做理论铺垫。第三章构建供应链融资企业间的相关结构。由于企业供应链融资风险具有相依性，Copula结构可以度量这种风险的相依性，进而可以度量供应链融资整体违约风险。研究中选取阿基米德Copula函数来度量供应链上企业的整体相关性，建立企业间的Copula相关结构。第四章运用信息熵法对企业的财务风险状况进行评估，得到企业财务状况得分的概率分布，进而得到财务风险违约的概率值。基于Copula相依结构计算出企业供应链融资的整体财务风险违约概率值。第五章利用GARCH-M模型，估计出企业收益率的波动率，然后利用KMV模型计算出企业的信用违约距离，利用修正的KMV模型我们计算出企业发生信用违约风险的概率，基于Copula相依结构度量企业供应链融资的整体信用违约风险概率值。第六章利用结构方程（SEM）的验证性因素分析（CFA），对财务风险的结构模型进行检验，通过模型输出的因素负荷量，得出指标变量对潜在变量的解释能力。再利用二阶验证性因素分析，得出一阶潜在变量对财务风险的解释能力、潜在变量间的相依程度以及模型整体的组合效度。第七章建立风险预警系统。采用循环修正的组合评价方法对企业供应链融资的财务风险和信用风险的排名结果进行修正，得出企业供应链融资风险排名，构建风险等级色彩预警系统。利用验证性因素分析结论建立企业供应链融资风险识别指标体系。研究的主要结果：1.构建企业间多元阿基米德Copula相依结构；2.结合信息熵和Copula结构度量供应链融资的财务风险；3.用GARCH-M模型估计企业收益的波动率，结合KMV模型和Copula结构度量供应链融资的信用风险；4.利用结构方程理论分析供应链融资违约的影响因素；5.用循环修正的组合评价方法对供应链融资风险的度量结果进行循环修正。根据上述研究结果构建供应链融资风险预警系统和供应链融资风险监控系统。更多还原

【Abstract】 In recent years, financing difficulties of enterprises has always been one of mainfactors hindering the economic development of China. And the government introducedmany policies and measures, trying to solve these problems, but the effect is still to beimproved. The root of them lies in the lack of financing credit qualification, high defaultprobability resulted from low default cost, and tough supervision and management.However, with the development and innovation of supply chain finance business, supplychain financing makes it possible to solve the problems. The most striking feature ofsupply chain lies in the closed property of enterprise finance on supply chain, namely thepartial closure derived from capital and goods flow within the supply chain. The smalland medium-sized enterprises occupy an crucial position in the upstream anddownstream of the supply chain, forming a close symbiotic relationship with coreenterprises, whose good operating performance and creditworthiness will be efficientlypassed on to them through the integrity of supply chain.In the supply chain financing, the financing default probability is low, in that bysupervising and managing the real rights and accounts, the bank can directly get businessdynamic information and effectively guard against and even evade the defaults. ForBanks the risk management is mainly focus on evaluating the risk before financing, so anobjective and accurate risk measurement can make the bank effectively evade financingdefaults. Therefore, to satisfy the needs of enterprises, meantime, considering thebusiness features of supply chain financing, providing a brand-new risk measurement andmonitoring system becomes a priority.Most people in domestic focus more on the operation, management and theories ofrisk types of supply chain and pay less attention on risk measuring. And more qualitativeanalysis methods, more summarily analyzing the types and features of risk， lessintuitively assessing methods and quantitative model; In terms of supply chain financingrisk measurement, more from the perspective of financing enterprises, measuringsingle-enterprise financing default risk, less from the perspective of financial institutionsto assess the risk of the whole supply chain, ignoring the integrity of the supply chainfinancing. However, the integrity is the most striking feature. Therefore, based on the integrity, we set up financing risk measurement model, andbuild warning and monitoring system of supply chain financing risk for banks, which isthe main research conclusions. The chapters’ overview is as follows:In chapter1we expound the topics, including the background, the present situation,purpose, content, significance and innovative points, and some others. In chapter2wearrange the basic theory of supply chain financing risk, preparing for the followingresearch.In chapter3we construct the relational structure among the enterprises.Archimedes’ copula function is used in our research to estimate the pertinence and thenconstruct the relational structure among the enterprises, in that the pertinence ofenterprise’s financing risk has dependency with each other, and the copula function canestimate it and then apply the results to the whole supply chain.In chapter4we evaluate the financial risk of the enterprises through informationentropy method, find the distribution probability of enterprises’ scores, and analyze theprobability of financial default risk. Then copula relational structure is constructed tocalculate the probability of financial risk of the supply chain.In chapter5we estimate the volatility of enterprise profitability by GARCH-Mmodel and calculate the credit default distance of enterprise by KMV model. Throughmodified KMV model we calculate the occurrence rate of credit default. Then we can usecopula connect dependent structure to measure the market default probability in thesupply chain.In chapter6by the confirmatory factor analysis (CFA) of the structural equation(SEM) we check the structural model of financial risk and get out to what extentindicator variables can explain the potential variables through factor loading from ourmodel. By second-order CFA, we find out to what extent the first-order potentialvariables will affect the financial risk and to what degree the potential variables dependon each other and the validity of the combination of the whole model.In chapter7we build up risk warning system, correct the ranking results of financialand credit risk of enterprise financing by circularly revised combination evaluation model,and get the ranking results of enterprise financing risk based on supply chain, then wecan build up colored risk level warning. Finally by CFA we build up enterprise financing risk indicator identifying system.Our main innovation:1. construct the relational structure among the enterprises byArchimedes copula function;2. measure the financing risk of the supply chain financingby the information entropy and copula connect structure;3. estimate earnings volatilityby GARCH-M model, combine KMV model and copulas connect structure to measurecredit risk of supply chain financing;4. analyze the influence factors of supply chainfinancing by SEM theory5. constantly correct the results of supply chain financing bycircularly revised combination evaluation model.更多还原
