Prioritising land to be preserved for agriculture: A context-specific value tree

In Belgium as in many other countries, agricultural land is under pressure for development of other land uses. This paper presents a method for setting priorities for preservation of land for agriculture. The method is based on a participatory approach through which a value tree is formulated. This results in a list of criteria to define farmland value, which is explicitly linked to the objectives for farmland preservation. The value tree allows the list of criteria to be determined in a structured and consistent way. The participatory process contributes to the development of a shared vision on farmland preservation. The approach also incorporates context specificity, as shown by its application for farmland preservation in Flanders.     

公允价值会计:理论分析与经验证据

公允价值会计一直是会计准则制定者与银行界及其监管机构之间争论的焦点.围绕着公允价值会计的争论全面而系统地综述了国外关于公允价值会计对银行业及监管影响的相关研究成果.从历史成本向公允价值转变确实会对银行业及其监管、乃至整个金融体系产生重大影响,在决定是否采用公允价值作为财务报表的主要计量手段之前,需要对公允价值所产生的影响做出不断深入的研究.

基于过程管理视角的开放式创新关系治理研究

开放式创新集价值创造与价值获取于一体,对于促进合作研发与创新成果转化具有积极作用。但是,创新主体间目标分歧、利益冲突等关系治理问题影响创新绩效与商业化成败,已成为制约开放式创新实践的主要障碍。基于“知识搜索→知识整合→商业化”的过程管理视角,考察了开放式创新关系治理问题的表现与产生机理,发现解决关系治理问题的关键是维护价值创造与价值获取间动态均衡,提出了以信任及关系规范为主体的关系治理机制理论框架,并从合作关系的内在规则与外在行为两个方面论证了关系治理机制的作用效果。     

考虑吸收能力的区域创新多维溢出效应

合理利用区域创新的空间溢出效应和价值链溢出效应,有助于区域创新发展与创新效率提升,而对区域创新溢出效应的利用程度则受其吸收能力影响。将创新过程分为知识创新阶段和产品创新阶段,利用Network Slacks-based Measure模型计算全国内地30个省域两阶段创新效率,将吸收能力引入空间溢出效应和价值链溢出效应对创新效率影响的研究中,并构建空间计量模型,检验吸收能力对知识创新效率和产品创新效率的影响。结果发现,空间溢出效应在部分年份显著,省域间没有形成稳定的空间关联关系;空间溢出效应显著时,提升吸收能力对知识创新效率和产品创新效率均有促进作用;价值链溢出效应不显著或者存在负向影响,创新过程两阶段相对独立,此时提高吸收能力对知识创新效率和产品创新效率提高没有显著作用,甚至具有负向影响。     

基于人力资本价值链理论的中国城市国际人才集聚研究

城市国际人才争夺战由来已久并不断升级,但针对中国城市国际人才集聚水平、影响因素和差异化政策供给的研究鲜见。以“国际人才集聚指数-国际人才集聚影响因素-国际人才集聚政策”为研究主线,以中国36个主要城市为研究对象,创新性地通过构建人力资本“投入-过程-产出”价值链理论模型进行实证研究,结果表明：中国城市国际人才集聚指数排名分为3个差异显著的层级。其中,第二和第三层级之间无较大差距,但与由北京、上海组成的第一层级相比大幅落后。中国城市国际人才集聚影响因素分化明显,第一类城市的主要影响因素为全球城市品牌文化;第二类城市为创新型经济发展;第三类为外资传统工商业企业和产业集聚。对应地,中国城市国际人才集聚政策供给围绕外资传统工商业国际人才集聚、高端生产性服务业国际人才集聚、多样性和包容性国际人才文化氛围营造存在三大差异化选择。首次构建人力资本“投入-过程-产出”价值链模型,为从机理上深入探索中国各类城市国际人才集聚模式及提升路径奠定了基础。     

Forecasting value at risk and expected shortfall with mixed data sampling

I propose applying the Mixed Data Sampling (MIDAS) framework to forecast Value at Risk (VaR) and Expected shortfall (ES). The new methods exploit the serial dependence on short-horizon returns to directly forecast the tail dynamics of the desired horizon. I perform a comprehensive comparison of out-of-sample VaR and ES forecasts with established models for a wide range of financial assets and backtests. The MIDAS-based models significantly outperform traditional GARCH-based forecasts and alternative conditional quantile specifications, especially in terms of multi-day forecast horizons. My analysis advocates models that feature asymmetric conditional quantiles and the use of the Asymmetric Laplace density to jointly estimate VaR and ES.     

Customer acceptance of four types of hospitality value propositions

Although how successful hospitality companies create value propositions has received some interest, how and why customers accept value propositions remains largely unknown. Grounded in theory of acceptance and service-dominant logic, this study examined consumers’ psychological mechanism of acceptance of value propositions at different points of exchange, and investigated the impact of value propositions acceptance on customers’ well-being and perceptions of service advantage. Online respondents (N = 180) assessed four hospitality value propositions: innovation, marketing, production, and recovery. Repeated-measures ANOVA and PROCESS Model analyses revealed that customers accepted value propositions cognitively, emotionally, normatively, and behaviorally, positively influencing subjective well-being and perceptions of firm’s service advantage. Service production and recovery value propositions had higher acceptance compared to innovation and marketing. This study is the first to empirically illustrate the complex process of customer value proposition acceptance and the effects on personal and organizational outcomes. Theoretical and practical implications are provided.     

基于自由现金流量的企业价值评估:以索芙特公司为例

本文在介绍自由现金流量折现法相关原理的基础上,选取一家名为索芙特的化妆品上市公司,通过分析该上市公司过去五年的相关财务数据,并结合整个化妆品的行业环境以及该企业的发展现状,分析影响企业价值评估的宏观环境和微观环境,进而探究该公司未来五年的自由现金流量。依据两阶段自由现金流量模型估算出索芙特公司的价值。基于此,本文从调整资本结构,提高公司自由现金流量的增长率两方面对索芙特公司的价值管理提出建议。     

基于金融衍生工具组合的财务风险管理

本文将金融衍生工具套期保值这一行为作为一种投资行为。在分析各种金融衍生工具单独使用进行套期保值时带来的操作性非系统风险的基础上,借鉴投资组合的基本理论,使用组合的金融衍生工具套期保值,从而既可以达到单独使用金融衍生工具控制财务风险的目的,又可以在一定程度上降低由于金融市场自身极强的波动性带来的风险,具有一定的现实意义。
