Airline Alliance Revenue Distribution Considering Horizontal and Vertical Competition

Considering the existence of multi-level fares in the alliance,and the existence of horizontal competition and vertical competition at the same time,this paper intends to maximize the revenue of airline alliance and fairly distribute the revenue to member airlines.Firstly,a model is built under the centralized mechanism,in which all airlines in the alliance are regarded as a whole.By solving the model,the shadow price of each flight leg on the code-sharing route is gotten.It is used to calculate the proportion of the revenue distribution.Then,the centralized model is decomposed into the single airline model by the proportion.The seat allocation among airlines and distributed revenue can be gotten by solving the model.Three typical examples are designed to test it.The results show that,the model can effectively reflect the managerial principal of the airline alliance,that is maximizing total revenue and fairly distributing the revenue among member airlines.

Analysis of high-speed rail and airline transport cooperation in presence of non-purchase option

We study cooperation between the airline and high-speed rail(HSR) sectors by formulating their joint profit as a maximization problem using a multinomial logit choice model in a three-node setting. We allow the nonpurchase option as an outside option available to consumers. The demand for each choice is not only a function of the price but also the service quality, such as the total trip time, frequency of service, and ease of connecting from the hub to a nearby HSR station. As a result, the following findings are presented. First, regardless of the service quality of either sector and the non-purchase option,cooperation decreases the total volume of the domestic market of a country. Second, when the attractiveness of the outside option is high, the HSR and air sectors can prevent a large reduction in the total volume by cooperation in the connecting market. However, this is not the case in the domestic market. Third, if the non-purchase quality in the domestic market is high, then cooperation increases the social welfare of the whole market. If the non-purchase quality is low, then cooperation increases the welfare of the whole market only in cases where the number of potential customers in the connecting market is relatively large. We also show the effect of improving air–rail service quality on each market share and on the total profit.

Empirical Study of Parameters of Airlines Sustainability in Nigerian Domestic Network

Sustainability was investigated in the ability to reliably anticipate airline market share, which is critical for effective business strategy. As a result, a model was created to address the issue of airline market share across all Nigerian airport routes. The model took into account the explanatory variables average fares paid by various airlines passengers, number of competitors at each route, frequency of flight, and the total number of enplaned passengers. The model illustrated how it may be used to determine an airline’s sustainability. It was observed that all of the parameters in the model were statistically significant and exhibited the predicted signs. As a result, the market share of Nigerian airlines can assess the sustainability of Nigerian airlines. As a result, it is proposed that the federal government and aviation regulatory bodies provide a level playing field to all commercial airline operators, without any kind of protectionism. Airlines’ services should be completely deregulated, and the forces of perfect market competition should drive the airline’s overall health. The government should provide a fair and supportive climate for airline operators as soon as possible. The ease of doing airline business must be implemented honestly and competitively. The degree of competition has a detrimental impact on the airline’s market share, especially if the airline operates in a regulated market. As a result, perfect competition for the airline should be promoted.

A new approach to assessing the science and technology competitiveness of China's provincial academies of sciences

Purpose： This study aims to establish a new framework for evaluating science and technology （S＆T） competitiveness that is appropriate to meet the needs of provincial academies of sciences （PASs） in China.Design/methodology/approaches： An evaluation index, including such assessing indicators as research strength, research impact, research development and trends, and regional contributions, is developed for China＇s PASs. Taking the Jiangxi Academy of Sciences （JXAS） as an example, we first explain how to apply this framework to analyze the strengths and weaknesses of PASs in China. Then, we compare the results of all 17 PASs in order to get a comprehensive understanding of their competitiveness.Findings： Our results show the development path, current status, innovation advantages, and weaknesses of JXAS very clearly. Based on our comparative analysis, we ranked the 17 PASs from the perspective of different dimensions, by which their competitiveness strengths and weaknesses can be highlighted for improvement.Research limitations： In this analysis, we did not take S＆T policies, S＆T systems, or historical factors into consideration. Thus, we may have ignored the influence of the soft individual differences of different PASs in China..Practical implications： The evaluation index developed in this paper provides a useful insight into an analytical method that can be used by PASs or other provincial research institutions （PRIs） to assess their competitiveness.Originality/value： Compared with existing evaluation frameworks, our method has two main characteristics： First, we added three new dimensions, including the PASs＇ applicable research outputs, regional contributions, and comparative advantages; second, we conducted a comparative analysis of local research institutes in their different advantaged industrial areas, which makes our analytical method more comprehensive for local research institutions.

URBAN COMPETITIVE PATTERN AND ITS CHANGES IN CHINA

With the national economy’s transition from a planning one to a market one, the factors affecting regional economic pattern has changed greatly. In this paper we first construct an index system for evaluating competitiveness of Chinese cities based on modern competitive advantage theory. With principal component analysis and cluster analysis methods, we compare the factors affecling cities’ integrated competitiveness in 1990 and 1997. We find that four major factors are capital (including investment, FDI and urban financial revenue ), urban ithestructure (transporiation and communication, urbanization level, education etc. ), industrial performance and structure, degree of market openness and that these factors have become more advanced and complicated since 1990. Most Chinese cities are transforming from productive factors-oriented type to investment-oriented type and a few are becoming innovation oriented. The integrated competitiveness is closely related to cities’ scale, urban function, regional policy and degree of market openness and displays an uneven spatial pattern. The difference between the south and the north and the difference between the west and the east co-exist bul the former has been more larger. Finally, we discuss the mechanism behind the pattern and attribute the unevenness to change of factors dominating the cities’ compehtiveness regional innovation capacity and geographical differenceof traditional culture.

Quantification of anaerobic ammonium-oxidizing bacteria in enrichment cultures by quantitative competitive PCR

The anaerobic ammonium-oxidizing （ANAMMOX） bacteria were enriched from a sequencing batch biofilm reactor （SBBR）. A quantitative competitive polymerase chain reaction （QC-PCR） system was successfully developed to detect and quantify ANAMMOX bacteria in environmental samples. For QC-PCR system, PCR primer sets targeting 16S ribosomal RNA genes of ANAMMOX bacteria were designed and used. The quantification range of this system was 4 orders of magnitude, from 10^3 to 10^6 copies per PCR, corresponding to the detection limit of 300 target copies per mL. A 312-bp internal standard was constructed, which showed very similar amplification efficiency with the target amxC fragment （349 bp） over 4 orders of magnitude （10^3-10^6）. The linear regressions were obtained with R^2 of 0.9824 for 10^3 copies, 0.9882 for 10^4 copies, 0.9857 for 10^5 copies and 0.9899 for 10^6 copies, respectively. Using this method, ANAMMOX bacteria were quantified in a shortcut nitrification/denitrification-anammox system which was set for piggery wastewater treatment.

China-US High-Tech Competition,Trade Conflict and Development Rights

The power and interest of industrial manufacturers are determined by their status in the relations of production.At the international level,countries see their economic and political status rise only when they climb the ladder in the international division of labor.As the primary production forces,science and technology are the main drivers behind such change.As new technologies give rise to new industries and restructure the international division of labor,developed countries strive to enhance the protection of their intellectual property rights(IPR)and safeguard their monopoly over core technologies.For developed countries,technological prowess holds the key to their supremacy in the global supply chain and international relations.The 19 th CPC National Congress makes clear the overarching goal in the new era is to rejuvenate the Chinese nation and turn China into a strong modern country.As an important material condition for achieving this goal,China must transition from being medium-and low-end links in the international division of labor to becoming high-end links.In this process,China will encounter backlash from developed countries that lead in the international division of labor.The recent China-US tussle over trade in high-tech goods is a case in point,and should be viewed through the lens of the relations of production and the international division of labor.The insights thus achieved will be of great significance to China’s future development.

Combined soft measurement on key indicator parameters of new competitive advantages for China’s export

The estimation of the difference between the new competitive advantages of China’s export and the world’s trading powers have been the key measurement problems in China-related studies.In this work,a comprehensive evaluation index system for new export competitive advantages is developed,a soft-sensing model for China’s new export competitive advantages based on the fuzzy entropy weight analytic hierarchy process is established,and the soft-sensing values of key indexes are derived.The obtained evaluation values of the main measurement index are used as the input variable of the fuzzy least squares support vector machine,and a soft-sensing model of the key index parameters of the new export competitive advantages of China based on the combined soft-sensing model of the fuzzy least squares support vector machine is established.The soft-sensing results of the new export competitive advantage index of China show that the soft measurement model developed herein is of high precision compared with other models,and the technical and brand competitiveness indicators of export products have more significant contributions to the new competitive advantages of China’s export,while the service competitiveness indicator of export products has the least contribution to new competitive advantages of China’s export.

The Biden Administration’s Scientific and Technological Competition Strategy toward China

Scientific and technological(S&T) competition has become a core and frontier issue in the ongoing China–U.S. strategic competition and the main focus of both countries. Currently, the Biden administration is adopting an S&T competition strategy toward China based on the “small yard, high fence” tactical logic, which involves three pillars: investment to make America strong, alignment to get things under control, and competition to weaken China. In the current context of the China–U.S. competition entering a new normal, five inherent contradictions, namely, the gap between strategic expectations and policy effects, shortfall between action capabilities and policy objectives, push-and-pull between strategic deployment and domestic politics, clash between strategic intentions and the S&T innovation ecosystem, and divergences between American priorities and the interests of American allies, will dictate how this administration will implement its S&T competition strategy toward China.
