ABSTRACT

Following a Chinese saying: To be rich, roads first, high-speed rail (HSR) opening and station construction are indispensable for economic developing. Probing the nexus between HSR, as a vital part of modern transportation system, and local tourism development provides a scan for reviving tourism and gaining low-carbon transition after COVID-19 pandemic. Drawing on prefecture-level panel data, this study takes difference-in-difference and instrument variable methods to detect the overall and heterogeneous effects of HSR connection on cities' tourism development. The results showed that HSR connection had an overall positive effect on cities' domestic tourist arrivals. The heterogeneity of the effect from HSR to tourism development appears to be that central and western cities, non-resource-based cities, and small cities benefited more from the opening of HSR. From a dynamic perspective, HSR connection promoted local tourism development in the 0 and 1 year of HSR opening but failed to show a positive effect in the long term. Hence, the study proposed some adjustments for evaluating the efficiency of HSR with consideration for the tourism effect, redesigning the system of HSR with consideration for local heterogeneity, and optimizing the HSR environment. These measures can optimize China's HSR management and the design of HSR systems.

ABSTRACT

This study tried to evaluate the effects of Frequent Flyer Programs (FFPs) in competition with High Speed Rail (HSR) by conducting conjoint analysis, using data from our questionnaire surveys at Komatsu airport in Japan. The effects of FFPs, which were evaluated as passengers’ Marginal Willingness to Pay (MWTP) for flight mileage points, were compared with passengers that flew on the competing route with HSR, and those that flew on the non-competing route with HSR. We found that FFPs seem to be more effective at attracting not only FFP members on business, but also FFP members not on business, on the competitive route with HSR. However, the power of FFPs to increase customer loyalty would become weaker after the COVID-19 pandemic if we consider the negative impacts of COVID-19 on business travel demand. On the other hand, when we focus on the non-business passenger, after the pandemic, FFPs would still be effective at cultivating customer loyalty on the competitive route with HSR.

ABSTRACT

Network control theory is first applied here to study the controllability of a High-speed Rail Network (HRN) in terms of delivering emergency supplies. The full controllability or target controllability of an HRN (i.e., controlling the amount of emergency supplies delivered at all stations or target control stations) can be achieved when the amount of emergency supplies transported from some appropriate stations is efficiently controlled. To identify the optimized controlling stations, a model is proposed for minimizing the number of controlling stations and maximizing the sum of trains departing from controlling stations, which effectively and quickly controls an HRN in terms of delivering emergency supplies. The proposed model is demonstrated in a case in which the delivery of emergency supplies by China’s HRN is controlled during the COVID-19 epidemic. The result shows that the sum of trains departing from the optimized controlling stations obtained through the proposed method is higher than that of the optimized controlling stations obtained through the commonly used maximum match method, and thus, the proposed method can obtain a better solution. The proposed method helps operators to identify the optimized controlling stations for effectively controlling an HRN in terms of delivering emergency supplies, and thus helping respond to emergency events.

ABSTRACT

Due to events such as natural disasters and navigation equipment failures, enormous calamity may be caused by the interruption of the navigation network which is a guarantee for the flight safety of civil aviation aircraft. The navigation network consists of the navigation stations as nodes and the routes between them as edges. Different nodes have different effects on the vulnerability of the network due to their different abilities to maintain the stability of the network topology and the normal function of the network. To quantify this difference and identify key nodes that have a greater impact on the vulnerability of the navigation network, an indicator to assess the importance of a navigation station is proposed which combines the structural importance reflected by node topology centrality and functional importance reflected by node weight. The structural importance of a node corresponds to its topology features including local dominance of the node and its global influence, and the important contribution to both adjacent and nonadjacent nodes from this node, while the functional importance is indicated by the flight flow serviced by the node during a fixed period of time. Vulnerability evaluation shows that the navigation network is more vulnerable when subject to the intentional attack of nodes with higher comprehensive node importance than an intentional attack of nodes with a larger value of indicators used in previous literature. Finally, the vulnerability of the navigation network is improved through changing the topology of the most critical node and balancing the node importance of the whole network.

ABSTRACT

Background: Nowadays, a gradual change in customers’ attitudes towards transport service makes it more challenging to understand the reasons behind customers’ travel decisions. High-speed rail (HSR) has been mentioned recently and is expected as the best and most modern transport option in long-distance trips in Vietnam. However, research studies have paid scant regard to how HSR’s attributes may affect potential users, and therefore the motivations and barriers to adopting HSR are still unknown. Objectives: This study aimed at examining motivations and barriers to take-up HSR for considering customers’ preference on the proper attributes and levels of HSR. Method: This study drew on a nationwide survey and conjoint analysis to investigate customers’ behaviour. Results: In Vietnam’s context, HSR ticket was found to be the principal barrier to adoption, whereas the speed of HSR was identified as the least important behavioural driver amongst potential HSR users. The results show that HSR design and planning should provide a combination of minimum check-in and waiting time, a 20-min frequency, average speed of 250 km/h, all add-on services and facilities, ticketing of approximately VND 500–700 thousand per 300–500 km and nearby all-day parking. Conclusion: This investigation has demonstrated the value of conjoint analysis to compare a wide range of attributes associated with consumers’ decision to use HSR. The findings indicate that in countries such as Vietnam, in particular, where train usage is low, policymakers and transportation agencies seeking to boost the use of HSR must take attributes other than fare into consideration.

ABSTRACT

This paper investigates the impact of market structure and high-speed rail on China’s low-cost carrier Spring Airlines’ entry patterns during the pre-pandemic period. Dividing the air transport system into discrete distance segments (i.e., short-, medium- and long-haul) helps better reveal critical factors that affect the route entry of Spring. Given the existence of market power in China’s airline industry and the capacity constraints at major airports, Spring strives to enter routes that can accommodate more potential entrants without a strong response from incumbents and are connected with more concentrated or lower-capacity airports. The complementary and competition effects of high-speed rail are well-distinguished in different distance ranges.

ABSTRACT

Purpose> This paper aimed to study the optimal way to implement and subsequently manage the new metropolitan lines in the Kuwait city as well as to justify them from a social and economic-financial viability standpoint and the most important aspects of transport infrastructure projects viability. The implementation of new modes of transport in an urban environment requires the study of several factors that allow their incorporation on the transport system in the most efficient method. These factors include reviewing the organization of the transport system. The concept of transport system organization, financing models and common trends was defined. Finally, the Public Transport Authority was created to define global objectives and establish specific policies to achieve them was suggested.Design/methodology/approach> After the analysis of the “status quo” of transport systems organization, the financing and management schemes, both infrastructure projects and the provision of rail service were analysed. The characteristics of the PPP scheme (Public–Private Participation) contract, advantages and disadvantages, its structure, and the definition and share of risk (matrix of risk, rights and obligations of the parties) as a key element of the PPP contracts were defined. From this point onwards, the legal framework in force in Kuwait was analysed, particularly the administrative and commercial regulations applying to this project and the authors verified that the economic-financial viability analysis suggested before can be established under this framework.Findings> For the viability of these alternatives, the authors developed a simulation economic-financial model that reflects Financial Statements for the “Society Vehicle Project” and are considered some minimum thresholds of profitability, both from the viewpoint of the partners sponsoring the project as from the standpoint of lenders, which make attractive participation of private initiative. Finally, there was a short socio-economic analysis to justify the project implementation from a social standpoint. It analyses and quantifies the reduction of operating expenses of other modes of transport, travelling times, accident rates, environmental pollution etc. All these factors affect the quality of life of the population of Kuwait and are the main reason to carry out this project. Several recommendations were raised that aimed at preparing the projects, bidding and selection of private partner and the articulation and implementation of projects.Originality/value> This research contributes to the existing body of knowledge through setting the framework for metro projects in arid regions with the hottest temperature on Earth such as Kuwait where such projects are missing completely. This work will be very helpful to governments and municipalities in taking investment decisions. It sets the strategy for utilizing the best of decision-making theory, identifying the reliability advantages and finding the larger economic effects. This work identified, through the analysis of alternative management options generally used in underground and rail projects in different parts of the world, the most convenient alternative in developing countries. It also clearly showed, through the analysis carried out on governmental contributions, how to obtain economic viability for such types of projects. Finally, it helped drawing a roadmap for preparing the projects, bidding and selection of private partner and the articulation and implementation of projects in Kuwait and Gulf Cooperation Countries (GCC).

ABSTRACT

Chinese high-tech industry is going through a period of profound change. Since 2017, the U.S. government, first under the Trump administration, has waged a trade war against China, using punitive tariffs and export controls to target some of the largest Chinese high-tech companies. The underlying assumption of this U.S. trade policy, which has been maintained by the Biden administration, is that the rise of Chinese high-tech industry is primarily driven by "forced technology transfer," with Chinese government policy using the leverage of China's economic growth to compel foreign companies to transfer advanced technologies to Chinese firms.1 Under this assumption, the U.S. government can contain China's high-tech ambitions by using trade policy to cut off access of leading Chinese firms to advanced technologies developed in the United States. Since 2018, the Department of Commerce's Bureau of Industry and Security (BIS) has added hundreds of Chinese organizations and individuals to the so-called Entity List, usually on the rationale of restricting them from engaging in activities "contrary to the national security or foreign policy interests of the United States. Since late 2020, the Chinese government has organized a concerted campaign to transform the ecosystem for innovation. In November 2020, the regulators began their moves by asking Alibaba, once the poster child of China's booming Internet economy, to cancel the initial public offering (IPO) of its fintech subsidiary Ant Group, citing systematic risks and privacy concerns for its lucrative consumer loans business.6 Since then, the regulators have taken a series of actions, including anti-monopoly investigations, heavy fines, and new privacy regulations, to rein in the country's large Internet platform companies, such as Alibaba, Tencent, Didi, and Meituan, from abusing their technology and market positions to exploit consumers and workers.

ABSTRACT

PurposeA transportation connectivity strategy is a crucial part of an adaptive, congruent and sustainable tourism transportation system and is of concern to countries focusing on growing their tourism economy. This study aims to gain a better understanding of the relationship between transportation connectivity and the tourism economy through a configuration analysis.Design/methodology/approachThis study uses fuzzy-set qualitative comparative analysis on a sample of 153 cities in China to provide an understanding of the impacts of transportation connectivity strategies, with the co-effecting factors of socio-economic status, tourism resource endowment and hospitality capacity, on the development of regional tourism economies.FindingsThere are multiple paths that lead to regional tourism economic development (a high level of tourist arrivals or a high level of tourism revenue). High-speed rail can play a supportive role, while air travel or traditional rail remains central to the tourism economy. Socio-economic status (i.e. city size and city gross domestic product) and hospitality capacity are identified as crucial influencers for the development of the tourism economy.Research limitations/implicationsThis study confirms the validity of deploying configuration analysis (based on the equifinality theory) to establish the relationship between transportation and the tourism economy. The finding of more than one configuration led to a new consensus on how multiple factors influence the tourism economy.Practical implicationsSuggestions on transportation connectivity strategies for different regions are provided.Originality/valueThis study demonstrates the need to place greater emphasis on configurations that lead to tourism economy development instead of the effect of a single transportation mode.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is an ongoing pandemic that was reported at the end of 2019 in Wuhan, China, and was rapidly disseminated to all provinces in around one month. The study aims to assess the changes in intercity railway passenger transport on the early spatial transmission of COVID-19 in mainland China. Examining the role of railway transport properties in disease transmission could help quantify the spatial spillover effects of large-scale travel restriction interventions. This study used daily high-speed railway schedule data to compare the differences in city-level network properties (destination arrival and transfer service) before and after the Wuhan city lockdown in the early stages of the spatial transmission of COVID-19 in mainland China. Bayesian multivariate regression was used to examine the association between structural changes in the railway origin-destination network and the incidence of COVID-19 cases. Our results show that the provinces with rising transfer activities after the Wuhan city lockdown had more confirmed COVID-19 cases, but changes in destination arrival did not have significant effects. The regions with increasing transfer activities were located in provinces neighboring Hubei in the widthwise and longitudinal directions. These results indicate that transfer activities enhance interpersonal transmission probability and could be a crucial risk factor for increasing epidemic severity after the Wuhan city lockdown. The destinations of railway passengers might not be affected by the Wuhan city lockdown, but their itinerary routes could be changed due to the replacement of an important transfer hub (Wuhan city) in the Chinese railway transportation network. As a result, transfer services in the high-speed rail network could explain why the provinces surrounded by Hubei had a higher number of confirmed COVID-19 cases than other provinces.

ABSTRACT

This paper demonstrates that transportation networks may be used to assess and predict the regional risk of COVID-19 infection from the outbreak. We use China's high-speed rail (HSR) network at the scale of prefecture level to assess, based on a probabilistic risk model, the risk of COVID-19 infection from Wuhan to the country's 31 province-level regions at the early stage of domestic spread. We find that the high-risk regions are mainly distributed along the southern half of Beijing-Hong Kong HSR line, where a large number of infection cases have been confirmed at the early stage. Furthermore, the two components of the infection risk, namely, the probability (proxied by the region's correlation with Wuhan through HSR) and the impact (proxied by the region's population with mobility), can play different roles in the risk ranking for different regions. For public health administrators, these findings may be used for better decision making, including the preparation of emergency plans and supplies, and the allocation of limited resources, before the extensive spread of the epidemic. Moreover, the administrators should adopt different intervention measures for different regions, so as to better mitigate the epidemic spread according to their own risk scenarios with respect to the probability of occurring and, once occurred, the impact.

ABSTRACT

To understand the roles of different transport modes in the spread of COVID-19 pandemic across Chinese cities, this paper looks at the factors influencing the number of imported cases from Wuhan and the spread speed and pattern of the pandemic. We find that frequencies of air flights and high-speed train (HST) services out of Wuhan are significantly associated with the number of COVID-19 cases in the destination cities. The presence of an airport or HST station at a city is significantly related to the speed of the pandemic spread, but its link with the total number of confirmed cases is weak. The farther the distance from Wuhan, the lower number of cases in a city and the slower the dissemination of the pandemic. The longitude and latitude coordinates do not have a significant relationship with the number of total cases but can increase the speed of the COVID-19 spread. Specifically, cities in the higher longitudinal region tended to record a COVID-19 case earlier than their counterparties in the west. Cities in the north were more likely to report the first case later than those in the south. The pandemic may emerge in large cities earlier than in small cities as GDP is a factor positively associated with the spread speed.
