欧盟在1994年颁布了第一套《航空运输国家援助指南》,旨在建立约束各国对航空运输的援助行为准则。之后随着航空运输市场发展变化,在2005年和2014年又重新颁布了两套新的指南。其中2005年新增了对机场提供资金以及对从支线机场起飞的航空公司提供启动援助时需要遵守的准则,2014年进行了提供援助过渡期、使援助更加具有针对性、简化启动援助规则以及制定对机场和航空公司之间协议的援助规则等四大改革。欧盟的《航空运输国家援助指南》是对各成员国补贴标准的统一,立法体系完备,可操作性强,并且根据市场变化和新的补贴现象进行制定及调整,对我国建立航空运输补贴政策有借鉴意义,但另一方面,比WTO反补贴规定更为严格的约束可能会使成员国在和欧盟以外的其他国家竞争时处于不利地位。我国应吸取欧盟的经验教训,在考虑到国际竞争的情况下,结合现实情况制定一个可操作性强的透明的航空运输补贴政策。  相似文献

This paper discusses the European Maritime Safety Agency (EMSA). Through a chronological reconstruction, the study looks at the events that lead to the official birth of the Agency in 2003 and how it developed to its current state. The conceptual framework draws from cognitive policy analysis, a French political science perspective related to new institutionalisms. This approach emphasizes the role of the actors' own representations of their sector and the ways they fit within the socioeconomic system as a whole. This highlights the evolution of the stakeholders' positions and influence throughout the development process. Findings suggest that although considerable discrepancies between European representatives and those of the shipping industry were present in the context leading to EMSA's creation, the Agency has now established a working consensus confirming a greater implication of European authorities in the regulation of international shipping. The work also suggests that a greater attention to plays of power among stakeholders and how they translate in their representations could be pertinent to strengthen research in shipping policy.  相似文献

民航业务量预测是机场建设可行性研究的重要数据,通常对于业务量预测中存在的不确定性与风险问题,多采用确定的结果表示,其实这是对不确定性的一种简化。本文针对新建机场业务量预测中存在的历史数据缺失以及对未来发展判断存在的不确定性,以菏泽机场为例,利用动态聚类分析方法筛选出与其相似的机场,通过模拟回归建立货邮吞吐量的预测模型;在此基础上,针对模型中的随机因素,通过蒙特卡洛模拟对机场货邮吞吐量进行风险分析。本文提出的方法可为机场规划建设提供定量分析的理论依据,研究结果可为相关决策者提供数据支撑。  相似文献

In spite of the recent progress made in household activity analysis and travel budget studies, urban transportation modeling still remains a “not-too-well developed” research field. There are conflicting theories, analysis units are not uniform, terms are not precisely defined, basic studies of sub-systems involved are not yet completed, and many models lack behavioral background as well as basic attributes such as simplicity, sensitivity, compatibility, transferability and forecasting ability. Gaps in methodology may be partially responsible for this situation. There is an urgent need for simple, yet not primitive, easily applicable urban transportation models which can respond to the technical needs of planners and engineers. Lessons from the past, as well as experiences from other disciplines, suggest that future research should concentrate on: (1) new, “unconventional” approaches based on systematic, basic studies of all sub-systems involved; (2) proper definition and stratification of an analysis unit; (3) revision and unification of definitions, classifications, etc., in order to improve the behavioral background of the models; (4) dynamic rather than static approaches, able to describe feedbacks between transportation and land-use as well as between transportation demand and supply; (5) interrelations between subsequent sub-models, particularly between car availability, trip generation and modal split; (6) developing models which are not only sensitive to transportation policies but also to other local policies (e.g. land use, city development, social, etc.).  相似文献

A new procedure for generating optimal transport strategies has been applied in nine European cities. A public sector objective function which reflects concerns over efficiency, environmental impact, finance and sustainability is specified and a set of policy measures with acceptable ranges on each, identified. Optimal strategies based on combinations of these policy measures which generate the optimal value of the objective function, are identified, and compared between cities. Resulting policy recommendations are presented. The results demonstrate the importance of an integrated approach to transport strategy formulation. They emphasise the role of changes in public transport service levels and of fares, and of charges for car use. By contrast, new infrastructure projects are less frequently justified. In the majority of cities the revenues from car use charges are sufficient to finance other elements in the strategy. However, private sector involvement either in initial financing or in operation may be desirable. Revised objective functions to reflect private sector involvement are specified, and optimal strategies with private sector operation of public transport are also identified. The requirement to meet private sector rates of return for public transport operation typically results in lower frequencies and higher fares; charges for car use then need to be raised to satisfy public policy objectives, but system performance is reduced. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

Productivity, in terms of net value added per man-year of labor and capital input, provides a more useful yardstick of airline efficiency than the widely used indices representing average unit costs or labor productivity. Large variations in productivity between airlines, in particular between U.S. and European airlines, can be explained almost entirely by differences in level of service, demand patterns and route characteristics. A regression model calibrated on 1975 data for fourteen U.S. and fourteen European scheduled airlines indicates that productivity could be increased by changes in network shape though a more liberal exchange of traffic rights, greater specialization (in particular the limited involvement of scheduled airlines in the very low yield charter market) and consumer choice — by offering higher frequency, multi-city services.  相似文献

Global climate change will affect road networks during this century. The effects will be different in various parts of the world due to differences in local climate change and in the structure and properties of roads. In this paper, climate change projections are presented for climate variables that are most likely to affect the long-term performance of road networks in Europe. We apply four regional climate simulations up to the year 2100 using two plausible future emission scenarios. The results show that the changing climate will require significant adaptation measures in the near future in order to maintain the operability of the European road network.  相似文献
