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.     

弹性长轨枕在首都机场线的设计与应用

为满足首都机场线部分地段中等减振的需要,首次研制开发的弹性长轨枕,对弹性长轨枕的构造方案、荷载体系、配筋结构型式以及T3站实铺现场的落轴冲击减振时比试验结果等进行较全面的总结和分析.结果表明,与传统弹性短轨枕相比,弹性长轨枕轨道具有稳定性好、弹性垫层易于检查和更换等技术优势,推广价值较高.     

复合地层条件的盾构机适应性评估与再制造技术

针对南京地铁机场线复合地层的特点,特别是复杂多变的安山岩地层特性,以及工程筹划上对盾构设备需求量大的实际情况,选择两段区间隧道拟采用的3台既有复合盾构机进行适应性评估、再制造技术研究,确定设备改制后的性能指标,介绍盾壳、推进系统、刀盘刀具等主要系统的改制方案。改制后的设备均顺利完成了相应区间隧道的实施,可为同类条件下的盾构机选型或改制提供借鉴与参考。     

对《中华人民共和国反垄断法(草案)》的若干意见

2006年6月由国务院提请全国人大常委会审议的《中华人民共和国反垄断法（草案）》总体上基本可行，但需要进一步完善。本文从十个方面对其进行了评析。     

Demonstration of reduced airport congestion through pushback rate control

Airport surface congestion results in significant increases in taxi times, fuel burn and emissions at major airports. This paper describes the field tests of a congestion control strategy at Boston Logan International Airport. The approach determines a suggested rate to meter pushbacks from the gate, in order to prevent the airport surface from entering congested states and to reduce the time that flights spend with engines on while taxiing to the runway. The field trials demonstrated that significant benefits were achievable through such a strategy: during eight four-hour tests conducted during August and September 2010, fuel use was reduced by an estimated 12,250–14,500 kg (4000–4700 US gallons), while aircraft gate pushback times were increased by an average of only 4.4 min for the 247 flights that were held at the gate.

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.     

次贷危机下中国如何超越基于成本的竞争

当前由美国次贷危机引发的金融市场动荡继续蔓延,房地产业的衰退,消费和投资信心都创下新低,美国经济形势愈加严峻。美国经济可能出现的大幅减速,也会对世界经济造成一定的影响。在这种情况下国际贸易保护主义重新抬头,中国过去以廉价劳动力参与国际分工而形成世界加工厂的低价竞争利器遭遇寒冬。因此中国应该采用超越基于成本的竞争来实现和谐发展。
