对传统供需理论的反思

西方经济学中的传统供需理论已无法解释高档奢侈品"越贵越畅销"的消费现象.新综合供需曲线分为两部分,在"价格引发点"以下的部分遵循传统供需曲线的运动机理,而在"价格引发点"以上的部分则遵循新的运行规律,即价格越高.需求越强劲,而供给则减少.价格升高反而需求强劲是因为一般效用之外的额外效用在发挥消费的主导作用;价格升高时供给反而减少是由于进入壁垒的增高和已进入企业的主动限产.这一理论可以有效解释高档市场"反常"的消费现象.     

基于顾客满意度的绿色采购决策研究

从提高顾客满意度(CS)的视角,研究了生态供应链(ESC)环境下绿色采购决策优化问题。利用两状态、时间离散的Markov链描述了CS的动态转移过程,以赋值形式引入利润变量,建立了ESC绿色采购决策的随机优化模型,体现了顾客导向的思想;并且给出了应用算法释例。     

测度政府层级条件下公共产品最优供给规模及供给效率的模型与方法

政府供给公共产品的最优规模与效率的分析是困难的，借用分级条件下政府供给公共产品最优规模的模型和政府供给公共产品的数据包络分析（DEA）模型，为量化政府供给公共产品的效率提供理论依据；同时，根据IMD测度政府效率的指标体系和国内相关的研究实践，探讨了分析政府供给公共产品的效率的具体方法，并提出了相应的政策建议。     

中国国债的货币供给量效应：理论诠释与实证分析

本文通过理论与实证分析得出结论，我国国债发行已产生显著的货币供给量倍数扩张效应。因此，政府应高度重视并正确运用国债发行这一调控工具，把它与财政政策和货币政策协调运作有机地结合起来，提高调控宏观经济的水平。     

我国农村公共产品供给的制度困境及对策选择

农村公共产品供给效率低下是我国三农问题中的一个长期症结，这既体现了公共产品供给的一般问题，也反映了我国农村公共产品供给的特殊矛盾。本从供给制度的角度剖析了我国农村公共产品供给的困境，并初步探讨了相应的配套改革措施。     

后疫情时代我国供应链管理发展趋势分析

指出新冠肺炎疫情给世界带来了深刻而广泛的影响,全球供应链的发展也遇到新的问题。在此背景下,利用SWOT分析法,对我国供应链管理的优势、劣势、面临的机会和威胁等进行了分析,同时对这些要素进行交叉分析,得出我国供应链管理发展的SWOT策略矩阵,为未来我国供应链的发展提供参考。     

中俄跨境电商服务供应链发展研究——以全球速卖通为例

指出随着中俄跨境电商的迅猛发展,跨境电商平台之间的竞争不断加剧且竞争焦点逐渐从商品竞争过渡到供应链和整体服务水平的竞争。结合全球速卖通在俄罗斯的跨境电商服务供应链的运营情况,通过建立PEST-SWOT矩阵模型,分析全球速卖通在俄罗斯市场的服务供应链发展的竞争态势及宏观环境,并针对其存在的问题提出了优化路径。     

基于知识共享的供应链企业间协同创新行为研究

运用演化博弈论建立供应链企业间知识共享行为演化博弈模型,分析供应链企业间知识共享行为的演化路径和影响知识共享行为的影响因素。研究结果表明,供应链企业间选择知识共享的策略受到自身的知识水平、知识的吸收转化系数以及系统内知识共享的创新成果分配系数的影响,当企业间的知识类别和知识量越互补、企业的知识吸收转化系数越高以及创新成果分配系数越高时,企业会选择知识共享策略;而知识共享的成本、知识共享的风险越高时,企业间知识共享的意愿越低。     

Assessment and selection of management consultants: A comparative cognitive study between small- and large-scale companies

This paper explores alternative ways of evaluating and ultimately hiring a generalist consultancy for short- and medium-term projects, and how this is shaped by the size of the clients’ company. What buying factors do managers of small and large firms have in mind when hiring consultants for their projects?Instead of employing surveys incorporating predefined buying factors based on what the researchers think would be important, a cognitive mapping methodology - the repertory grid technique - is applied to investigate the underlying phenomena. Using the repertory grid technique to draw mental models is a novel research technique within the supply management field. Recent behavioral supply chain management research found the behavior of managers to be critically influenced by mental models: the lenses through which managers perceive, simplify and interpret the world.Results show differences between the buying factors used in small- and large-scale companies: managers of large companies are more ‘reputation and outcome-oriented’ and managers of small businesses are more concerned with ‘how the services are rendered’. However, both constituents stressed the importance of expertise, quality and the relationship between the client and the management consultancy, although the character of such a relationship differed between small- and large-scale firms. Results also point out criteria that managers of small and large companies employ to discriminate between good and poor performing consultancies and to judge service delivery. The practical implications for both companies hiring consultancies and the consultancy companies are discussed. For consultancies, our findings can help tailoring their efforts to a differing clientele when marketing and selling their services. For companies hiring consultancies, fixating too much on particular buying factors may lead to biased decisions.     

冬季油田压裂供水技术的研究及应用

石油是现代工业的“血液”,是国家生存和发展不可或缺的战略资源,对保障国家经济和社会发展以及国防安全有着不可估量的作用。油田钻井开发工程中的体积压裂技术在低渗透油田的开发中有着显著的增产效果,压裂供水是压裂作业的重要组成部分。我国西北地区冬季气候寒冷,为保障压裂作业在冬季正常开展,冬季的压裂供水研究和应用,对油田钻井开发具有重要的意义。
