Chefs and suppliers: An exploratory look at supply chain issues in an upscale restaurant alliance

This paper examines some basic issues associated with supply chains in the context of acquiring local ingredients as part of producing a culinary tourism experience. Based on data collected from Executive Chefs at Relais & Châteaux restaurants through surveys and personal interviews, the authors document producer-to-chef relationships, why and how local ingredients are featured in menu listings, and how chefs communicate their use of local ingredients to their guests. The results also describe chefs’ beliefs about the use of local ingredients, as well as potential issues related to the use of suppliers and their perceptions of their guests’ expectations for their meals.     

Market-based capabilities and financial performance of firms: insights into marketing’s contribution to firm value

While there is recognition that market-based capabilities contribute to a firm’s financial performance, the exposition is largely conceptual (Srivastava et al. Journal of Marketing 62:2–18, 1998; Journal of Marketing 63:168–179, 1999). Using a resource based view of the firm, the present study proposes that (1) market-based assets and capabilities of a firm impacts (2) performance in three market-facing business processes (new product development, supply-chain and customer management), which in turn, influence (3) the firm’s financial performance. It develops related hypotheses and tests the framework empirically. The study also examines for the first time the interrelationship among the three business processes and their impact on the market value of firms. Further, the study examines the moderating influence of two organizational variables—size and age of the firm. Overall, the major contribution of the study is that it offers a process linkage between capabilities, process performance and financial performance. The results of this research will provide strategic insights to managers on optimal customer management, product development and supply chain strategies.

Creating a model of customer equity for chain restaurant brand formation

The purpose of this research was to create and test a model of customer equity for chain restaurant brand formation. It has long been acknowledged that managing and enhancing customer equity influences a company's shareholder value, which is a reflection of long-term financial performance. A review of the current literature revealed three key determinants of customer equity: (1) value equity, (2) brand equity, and (3) relationship equity. Six hypotheses were derived and, based on data analysis, all six were supported. Value, brand, and relationship management were all confirmed to be important factors in enhancing customer equity in the chain restaurant industry. Further, brand equity has the strongest impact on the development of customer equity in this particular industry. Relationships among value equity, brand equity, and relationship equity were also identified. Managerial implications are discussed.     

纵向财政失衡、FDI竞争与医疗卫生服务供给水平——兼论标尺竞争机制下地区间的策略性行为北大核心CSSCI

关于医疗卫生服务供给不足的原因一直是社会各界高度关注的重点话题,现行的财政分权制度常被认为是最主要的原因。本文尝试将表征现行财政分权制度特征的三个要素,即纵向财政失衡、地区FDI竞争和地区间竞争模仿的策略性行为,与医疗卫生服务供给水平纳入同一分析框架,在对其理论机制分析的基础上,利用2007-2018年277个地级及以上城市面板数据,实证考察它们之间的关系特征及机制路径。研究发现,纵向财政失衡与地区FDI竞争对医疗卫生服务供给水平均存在显著的抑制作用,同时,地区FDI竞争对纵向财政失衡的负向抑制作用具有正向调节效应。进一步分析发现,地方政府间的标尺竞争使其在医疗卫生服务供给行为上表现出明显的策略模仿,医疗卫生服务供给水平呈明显的空间溢出效应。异质性分析发现,发达地区医疗卫生服务供给水平受抑制的主因是FDI竞争所致,欠发达地区则主要缘于纵向财政失衡的显著影响。机制分析发现,纵向财政失衡通过作用于财政支出结构与医疗卫生支出效率两种方式实现对医疗卫生服务供给水平的抑制,而FDI竞争则主要是通过扭曲财政支出结构的方式实现其抑制作用。本文的研究丰富了医疗卫生服务供给不足制度性成因探寻的文献,对于如何全面推进新一轮财税体制改革、深化医疗卫生体制改革、优化政绩考核指标等具有借鉴意义。     

农业供应链金融的数字化转型:理论与中国案例

随着农村电商、物联网和数字金融的快速发展,我国农业供应链金融开始向数字化转型,本文对数字化农业供应链金融模式进行理论和案例分析。研究发现,相比于传统农业供应链金融,数字化农业供应链金融借助于电商平台、物联网、大数据和云计算等数字应用和技术,能够降低金融服务过程中的交易成本,构建农村数字化信用评价体系,优化风险控制策略,最终提高金融供给效率。目前数字化农业供应链金融已形成互联网企业驱动和数字化农业企业驱动两种模式,但是仍面临资金成本高、数字足迹缺乏和信息孤岛等问题,限制其作用的发挥。未来应加快对传统农业的数字化改造,推动农村电商的发展,支持和规范涉农互联网金融机构的发展,最终完善数字化农业供应链金融模式,为发展中国家的农业供应链金融贡献创新模式。     

旅游服务供应链中若干环节的协调

自20世纪90年代以来,有些学者已经认识到供应链思想应用于旅游业的重要作用,从不同角度对旅游业的发展应加强供应链建设进行了探讨,而目前我国对旅游服务供应链的研究尚处于初始阶段.对于旅游业而言,旅游产品综合性的特点决定了单个旅游企业不可能提供完全的产品,此种属性同时也决定了旅游服务供应链的存在和形成.旅游服务供应链一旦形成,就需要我们考虑各个企业之间的衔接和协调问题.本文先叙述了旅游服务供应链的概念,然后应用博弈模型、经典报童模型就旅游服务供应链中若干环节的协调进行讨论并给出对策.     

THE BIAS OF THE MULTIPLIER MATRIX WHEN SUPPLY AND USE TABLES ARE STOCHASTIC

The literature on stochastic input–output (I–O) analysis has paid considerable attention to the bias in the Leontief inverse. This paper extends previous studies by assuming supply and use tables (SUTs rather than I–O tables or input coefficients matrices) to be stochastic. This is a natural starting point because SUTs have become the basic data sources for I–O applications. In a Monte Carlo simulation experiment, a given SUT is randomized in two different ways and the effects are determined for eight different multiplier matrices. The analysis is carried out for Spain, Italy, the Netherlands, Germany and Finland, using their SUTs for 2006. The findings indicate that, in general, biases are statistically significant but negligibly small. This corroborates earlier findings obtained for stochastic I–O tables.
