高技术产品定价模型研究——基于TCO和TVO均衡的视角

现行定价方法在应用于高技术产品时遇到困难,这主要是其价格结构中缺失拥有的总成本和拥有的总价值这两个要素所致.高技术产品的技术结构是影响价格决策的重要因素,这一影响通过拥有的总成本和拥有的总收益之间的交互关系或者说均衡关系得以实现.这一特征与一般产品,例如以标准化为导向的工业品或以消费者个性化为导向的消费品大相径庭,因此用一般产品定价方法为高技术产品定价显然是不合适的.文章构建了基于拥有的总成本和拥有的总价值均衡条件下的高技术产品定价模型,得到该模型的逻辑过程是:给出成本与预算双约束下的拥有的总成本曲线及此双约束下的拥有的总价值曲线,分别建立两组曲线内成本约束与预算约束的线性均衡关系,并通过两组线性均衡关系的均衡找到均衡价格.研究结论为高技术产品定价提供了参考.     

农业转移人口市民化的财政负担研究

新型城镇化的核心是农业转移人口市民化,而流入地政府的财政负担是市民化进程中面临的一大障碍。流入地政府需要增加额外的财政支出以实现公共服务均等化,这必然会对现有的财政收支结构造成一定影响,由此带来较大的财政成本,造成一定的财政负担。但随着相关配套制度及设施的逐步完善,市民化的积极意义会日益凸显,对流入地政府的财政负担也会逐渐减轻,最终有利于流入地经济社会的发展。因此,流入地政府应以积极包容的态度做好相关财政准备,加快农业转移人口市民化进程,形成“中央与地方共同分担,地方为主”的格局。     

Development of supplier relationship including cost of defectives in the cyclic production

In the supply chain situation, a decision regarding supplier relationship is of high importance. This usually happens on the basis of supplier company parameters. In order to satisfy the demands, a buyer company often expects the supplier company to expedite their operations, i.e., to enhance the related production rate. In this context, presently the focus of this article is on the cyclic production environment at the supplier company premises. Any practical production process is expected to generate defective products also along with the normal usable products. After an estimation of this and the costs concerning defectives, it needs to be modelled in the cyclic manufacturing. This article incorporates specifically the cost of defectives along with the other relevant costs. After developing an interest in the inclusion of these costs, the supplier company is categorised. A contribution of this article is the development of supplier relationship in the discussed environment.     

The use of performance measurement as a basis for project control of offshore modification oil and gas projects

The methods presented in this article are based on the qualitative and quantitative analysis of close-out data drawn from a portfolio of 38 modification projects. The primary premise is that modification projects are intrinsically subject to quantity and complexity growth during the course of detailed engineering as a consequence of the indeterminate interface with the existing facility. The normative project control routines need to be supplemented by material take-offs-based weight monitoring as a basis for re-estimation and re-calibration of the project baselines as detailed engineering proceeds in order to mitigate this uncertainty as early as possible. Similarly, estimating needs to be based on norms drawn from performance measurement of modification work rather than extrapolations from greenfield projects, particularly the work performed on the platforms. This article presents a portfolio of project control methods based on the performance measurement principle covering the short term of single projects as well as the longer term multi-project perspective.     

The Effects of a Combined Goal Setting,Feedback and Incentive Intervention on Job Performance in a Manufacturing Environment

Abstract

Baked anodes are used in finished aluminum production. Employees of a large multinational aluminum smelter were responsible for the production of more than 3500 baked anodes per week. During a 74 week long baseline (A) condition, production of unusable anodes exceeded 300 per week or 8.6 percent of their nominal 3500 anode production requirement. A problem analysis suggested that this high rate of defective anodes might have been due to weak antecedents, inefficient work procedures and weak performance contingencies. An intervention package that included a combination of goal setting, performance feedback, and tangible rewards was designed to strengthen antecedents and consequences of job performance. A performance feedback system was introduced with and remained constant across the three types of performance contingent rewards and three successively higher goal levels. The three reward and goal combinations were introduced to “strengthen” antecedents and performance contingencies within an A-B1-B2-B3-A with reversal to baseline conditions design. Anode reject rates were lower (better performance) during the three intervention phases compared to both the pre- and post-intervention baseline phase data. A dramatic performance improvement (lowered rate of rejects) was observed during the B3 phase that included the highest performance goal. These data demonstrate that a treatment combination of specific goal setting, feedback and tangible rewards can “strengthen” antecedents and performance contingencies resulting in improved objective performance in a manufacturing environment.     

融资约束与代理成本对上市公司非效率投资的影响——基于双边随机边界模型的实证度量

在有效地控制企业最优投资水平的前提下,本文将融资约束与代理成本同时纳入到前沿异质性双边随机边界模型(Two-tier stochastic frontier model)框架下对我国上市公司的非效率投资程度进行了实证度量,并探讨了各种财务因素对融资约束与代理成本的影响.实证结果表明:融资约束的存在使得上市公司的投资支出较最优水平低了37.5％,而代理成本导致上市公司的投资支出超出其最优水平的30.6％,两者的净效果使我国上市公司整体上表现为投资不足,投资不足率为6.9％.此外,流动资产净额和资本存量的增加有助于缓解公司面临的融资约束程度,而规模较大、持有较多自由现金流的公司内部代理问题更为严重,并且不同规模和地区之间的上市公司非效率投资程度存在较大的差异.     

基于临界价格的易变质产品生产企业 RFID技术投资决策

RFID技术可以优化易变质产品的流通速度,降低变质率对该类企业收益的影响。现代市场是开放型的系统,然而当前RFID技术投资成本过高,因此迫切需要研究开放系统下不同成本的易变质产品生产企业投资RFID技术的可行性。本文建立了不同成本易变质产品生产企业未投资RFID技术时的竞争博弈价格模型和合作博弈价格模型,分析了变质产品数量对产品定价的影响,得出竞合模式下保持企业较高收益且对新企业不产生吸引力的临界价格。在临界价格基础上,分析了投资RFID技术对易变质产品生产企业收益的影响,得出企业可承担的最大RFID标签成本,为该类企业RFID技术的投资提供了科学决策的依据。最后,通过数值模拟分析验证了所建立的模型。     

飞行频率、拥挤成本和互补型航空联盟:中枢轮辐网络机场拥挤分析

本文在基于飞行频率、拥挤成本和互补型航空联盟的基础上系统分析了中枢轮辐网络机场拥挤问题。研究表明:航空公司的利润最大化使得航班飞行频率存在过度供给,飞机大小也是次优的,这进一步恶化了中枢机场的机场拥挤;航班飞行频率与航空公司的拥挤成本系数、旅行计划延迟效用系数正相关,与飞机每次起降的固定成本负相关;互补型航空联盟使得联盟体利润增加,航空联盟对连接市场乘客有利,对本地市场乘客不利,航空联盟还可以内化伙伴间拥挤,航班飞行频率得以优化,机场拥挤得以缓解。     

中国民营企业政治关联与税收负担关系的研究

民营企业实际控制人及高管的人大代表、政协委员等政治身份,对企业的经营活动和税收可能产生重要影响。本文以在沪、深交易所上市的民营企业为样本,实证检验了政治关联对企业综合税负的影响。研究结果表明政治关联并没有给企业获得税负降低的利益;与之相反,政治关联企业的税收负担显著高于非关联企业,并且政治关联程度越强,企业税负越高,从而支持了政治关联对税负影响的"政治成本假设"。     

A Reply to Williamson's “Outsourcing …”

A recent article by Oliver Williamson essentially comprises a critique of supply chain management (SCM) from the perspective of his own field, transaction‐cost economics. Here is one reader's response. SCM can indeed be faulted for inflated rhetoric, among other sins. I believe, however, that the two fields have much to learn from each other.
