溢出效应与集群企业创新时间的选择

为考察溢出效应对产业集群企业创新时间的影响，将溢出效应系数引入创新时间和投入之间的线性函数以及创新成功时间的概率函数中，建立了集群企业创新期望净收益函数．将该收益函数对创新时间和溢出效应系数变量求出二阶偏导数以建立最优创新时间和溢出效应系数之间的一阶导数关系．对一阶导数符号的分析显示，当竞争企业数量较大时，无论创新类型、资金成本、研发风险参数如何变化，最优创新时间都随技术溢出效应的增强而缩短．     

地铁经济中的垄断与竞争

从地铁经营体制改革的角度,按照地铁运营活动的特征,将地铁经济分为客运经济、维护经济和附属经济三部分.通过对地铁经济中不同经济类型的分析,认为只有地铁客运经济具有自然垄断特征,适宜垄断经营;在探讨地铁运营垄断经营的评价时,主要考察其平均可变成本化.阐明地铁附属经济应该引入竞争机制,从地铁经营体制中分离出来,并探讨地铁附属经济引入竞争机制的效应.

A network optimization-based approach for crowd management in large public gatherings

Effective crowd management during large public gatherings is necessary to enable pedestrians' access to and from the venue and to ensure their safety. This paper proposes a network optimization-based methodology to support such efficient crowd movement during large events. Specifically, a bi-level integer program is presented that, at the upper-level, seeks a reconfiguration of the physical layout that will minimize total travel time incurred by system users (e.g. evacuees) given utility maximizing route decisions that are taken by individuals in response to physical offerings in terms of infrastructure at the lower-level. The lower-level formulation seeks a pure-strategy Nash equilibrium that respects collective behavior in crowds. A Multi-start Tabu Search with Sequential Quadratic Programming procedure is proposed for its solution. Numerical experiments on a hypothetical network were conducted to illustrate the proposed solution methodology and the insights it provides.

Game-theoretical models for competition analysis in a new emerging liner container shipping market

This paper develops three game-theoretical models to analyze shipping competition between two carriers in a new emerging liner container shipping market. The behavior of each carrier is characterized by an optimization model with the objective to maximize his payoff by setting optimal freight rate and shipping deployment (a combination of service frequency and ship capacity setting). The market share for each carrier is determined by the Logit-based discrete choice model. Three competitive game strategic interactions are further investigated, namely, Nash game, Stackelberg game and deterrence by taking account of the economies of scale of the ship capacity settings. Three corresponding competition models with discrete pure strategy are formulated as the variables in shipment deployment are indivisible and the pricing adjustment is step-wise in practice. A ɛ -approximate equilibrium and related numerical solution algorithm are proposed to analyze the effect of Nash equilibrium. Finally, the developed models are numerically evaluated by a case study. The case study shows that, with increasing container demand in the market, expanding ship capacity setting is preferable due to its low marginal cost. Furthermore, Stackelberg equilibrium is a prevailing strategy in most market situations since it makes players attain more benefits from the accommodating market. Moreover, the deterrence effects largely depend on the deterrence objective. An aggressive deterrence strategy may make potential monopolist suffer large benefit loss and an easing strategy has little deterrence effect.
