关于我国铁路运价问题的思考

针对我国铁路运价长期以来实行统一运价,且水平偏低、形式单一,不能真实反映市场供求关系的现状,提出改革铁路运价管理体制,形成多元化的运价运行机制和运价与物价联动机制,以及实行国家定价、政府指导价、浮动运价、区域运价、协议运价和优惠运价等灵活多样的运价体系,以增强铁路运输企业的竞争力,实现铁路的可持续发展。     

我国旅游业与民航客运业相关性研究及启示

民航客运业和旅游业之间的发展有很强的关联性,旅游业三大市场(国内旅游市场、出境旅游市场、入境旅游市场)都与民航客运业呈显著的正相关关系.因此,一方面要加强民航客运业与旅游业之间的合作,抓好国内旅游市场的客源,继续保持民航客运在出境游旅客中的绝对优势,开辟旅游特色航线,开发配合旅游业的民航特色服务,使民航客运业与旅游业在发展中携手共进;另一方面,民航客运业的发展要跟上旅游业发展的脚步,在运力、航线网络覆盖面等方面满足旅游业发展的需求,将旅游业对民航客运业发展的辅助作用发挥到极致.

Tourism's climate mitigation dilemma: Flying between rich and poor countries

Stronger demand for medium- to long-haul air transport is the main driver of the tourism industry's increasing greenhouse gas (GHG) emissions, causing the current development of global tourism to be environmentally unsustainable. Efficiency improvements and biofuel usage are unlikely to maintain pace with the projected growth in transport volume. Therefore, curbing the growing demand for air transport has been suggested as another option for the sustainable development of tourism. However, the political and industry discourse concerning the restriction of air transport tends to label such a restriction as unethical, as such limits would impair the development that tourism brings to poor countries. This paper investigates the possible impacts of air travel restrictions on the least developed countries (LDCs) and non-LDCs by examining global tourism. The impacts on LDCs are found to be ‘neutral’ on average, with both losses and gains in tourist arrivals. The extent of any losses does not appear to be beyond the scope of possible economic compensation.

Mediation Between Tourism Contribution and Economic Growth in the Greater Mekong Subregion

The objective of this paper is to determine the mediation between tourism contribution and economic growth in the Greater Mekong Sub-region (GMS) (i.e. Cambodia, Laos, Myanmar, Thailand and Vietnam). The sample period is semi-annual data from 1995 to 2013 and is also estimated by bootstrap panel cointegration, Panel Fully Modified Ordinary Least Squares method and the Sobel test. The results show that the variables are cointegrated as three models; economic growth is running to tourism's total contribution to GDP and international tourism expenditure for passenger transport whereas international tourism expenditure for passenger transport is running to tourism's total contribution to GDP. Therefore, this study finds that international tourism expenditure for passenger transport is a mediator and has partial mediation. The GMS needs to develop every economic sector and improve the potential of the transport sector as a regional integration project which supports the sustainable development of the region.

交通基础设施与经济增长:中国区域差距的视角

本文利用中国28个省市区1987—2007年的面板数据来验证交通基础设施对中国经济增长的影响,同时还检验交通基础设施在中国区域经济差距中所扮演的角色。基于一个巴罗类型的增长模型以及对该模型进行分解,本文的实证结果表明:交通基础设施对中国的经济增长有着显著的正向促进作用;不同的地理位置和交通基础设施条件在我国区域经济发展差距中扮演了重要的角色;1999年国家实施西部大开发战略有利于促进西部地区的经济增长与向中东部地区趋同,其中,西部地区交通基础设施的快速发展发挥了重要作用。

The relationship between public transport and the progressive development of rural areas

In a consequence of the economic transformation, transport companies compete for the most profitable lines of public transport whereas the wide countryside remains of a little interest. As a solution, integrated systems of public transport could play an important role in the development of rural areas, especially in post-communist countries. Such a system in the South Moravian Region connects 24 state, municipal and private transport companies in a unified mode. It includes unified tariff, operation management from one place, and creation of a skeleton of high capacity (train) lines with transfer traffic nodes, creation of nodes on the city fringe for the change from buses to electric vehicles and release of capabilities for tangential lines. The system competes mainly with the individual car transport by its increasing comfort and extension of services. The annual performances have increased from 118 to 829 million of passengers-kilometers in the regional transport and from 344 to 396 million passengers in the city during the period 2004–2015. The relation between accessibility and rural development, particularly depopulation trends, was investigated. It was found that the frequency of connections is sufficient throughout the territory, which is one of main reasons inhabitants should remain in the countryside. Moreover, this frequency contributes positively to rural tourism, prevents social exclusion and stimulates progressive rural development throughout the whole territory.
