企业效绩评价与经营者年薪挂钩研究

经营者年薪一般包括基本年薪和效益年薪两个部分。尽管全国各地普遍开展了经营者年薪制试点，但对年薪的确定很不规范，特别是对经营者经营业绩的评价缺乏科学手段。本文在运用企业效绩评价体系对经营者业绩进行科学评价的基础上，对如何确定经营者基本年薪和效益年薪，建立了一个基本模型，并选择了150户大型企业进行了模拟测算，使年薪制的实施具备了比较科学的技术基础。     

The formation of the tourist's loyalty to the tourism distribution channel: how does it affect price discounts?

Given that distribution agents who wish to maximize long‐term business profits should not only attract new consumers but also keep them loyal, this study analyses the variables that determine the consumer's loyalty to distribution agents for tourism. Although retailers in the service industry employ price discounts on products to motivate short‐term sales, they often establish promotional policies without considering their effect on the long‐term business results. This paper presents an empirical study of the effect of price promotions on tourists who travelled with a package tour. The results indicate that price discounts do not erode consumer loyalty directly, and that the key to obtaining loyal consumers is to offer package tours that customers perceive as providing high‐quality service.

家庭农场退出诱发的专用性资产问题研究

研究目的:明确家庭农场专用性资产的构成和特点,探究家庭农场退出对专用性资产的影响,提出家庭农场退出时专用性资产的处置策略与方案。研究方法:文献资料法、规范分析法。研究结果:在家庭农场退出时,应当妥善处理好专用性资产的闲置浪费、权利归属不清晰、价值评估与补偿等问题,否则,不利于家庭农场正常有序的进入机制和退出机制的构建。研究结论:(1)在家庭农场退出时,应通过家庭农场的整体转让、整体出租或者专业机构托管经营等途径,盘活专用性资产,帮助家庭农场主收回前期投资;(2)依据竞争性和排他性为标准,区分产品的不同类型,对照确定专用性资产的权利主体归属,并通过完善法律赋予设施农用地等专用性资产的物权属性;(3)组建家庭农场资产评估小组,建立公开、公正、透明的专用性资产评估程序,选择科学的方法评估专用性资产的价值,根据实际情况,合理确定专用性资产的补偿主体。

The competition among mobile network operators in the telecommunication supply chain

In the mobile telecommunication sector, the high competitiveness has increased the complexity of strategic interactions among operators. As the vertical integration has become anything but a choice and not a compelling technical solution, the contest takes place at different levels of the components of the operator value chain: the network infrastructure, the service development and supply, and the relationship with consumers.Mobile virtual network operators act as retailers and concentrate on the last segment of the value chain by establishing commercial agreements with hosting network operators, which act as manufacturers, to get access to radio communications infrastructure. Productive processes of mobile services offered by operators are different and this difference is imperceptible to customers. Processes difference mainly consists in the infrastructural diversity of the operators and implies different consequences on each network service element.A model has been defined to analyze the consequences of such diversity in the competition among HNOs, MNOs, and MVNOs by focusing the attention on the characteristics of the call path, in dependence of the types of operators. In fact, many variables interact to define the call path, such as marginal costs and revenues, infrastructural investments, and interconnection charges among operators. The analysis of the results, obtained by the model, gives information on variations of retail prices, market shares, and profit allotment, to adopt the proper strategies. In particular, the model results shed light on how certain MVNOs should enter the markets and adopt a collaborative strategy with HNOs. The model owns the capability of being applied to different contexts, thus representing for the regulator a potential instrument of relevant usefulness.
