技能大赛视野下中职学校汽车专业核心课程教学改革与实践——以《电控发动机检修》课程为例

长期以来,中职学校汽车专业对于技能比赛存在着"重成绩、轻转化"的现象,导致只有少部分教师和学生受益,这与技能大赛"以赛促学、以赛促教、以赛促改"的理念相背。本文以《电控发动机检修》课程为例,阐述了中职学校汽车专业基于技能大赛开展专业核心课程教学改革策略与实践成效,以期为中职学校汽车专业核心课程教学改革提供有益借鉴。

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.

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。     

A novel permit scheme for managing parking competition and bottleneck congestion

Morning commuters may have to depart from home earlier to secure a parking space when parking supply in the city center is insufficient. Recent studies show that parking reservations can reduce highway congestion and deadweight loss of parking competition simultaneously. This study develops a novel tradable parking permit scheme to realize or implement parking reservations when commuters are either homogeneous or heterogeneous in their values of time. It is found that an expirable parking permit scheme with an infinite number of steps, i.e., the ideal-scheme, is superior to a time-varying pricing scheme in the sense that designing a permit scheme does not require commuters’ value of time information and the performance of the scheme is robust to the variation of commuters’ value of time. Although it is impractical to implement the ideal-scheme with an infinite number of steps, the efficiency loss of a permit scheme with finite steps can be bounded in both cases of homogeneous and heterogeneous commuters. Moreover, considering the permit scheme may lead to an undesirable benefit distribution among commuters, we propose an equal cost-reduction distribution of parking permits where auto commuters with higher value of time will receive fewer permits.
