Multi-stakeholders’ assessment of bike sharing service quality based on DEMATEL–VIKOR method

ABSTRACT

Bike sharing is a sustainable mode of urban transportation. Assessing the perceived service quality is essential to improve the development of bike sharing. Most of the existing research evaluates the service quality of bike sharing only from the perspective of its users. This study assesses the perceived quality gap among four different stakeholders including government regulators, platform operators, bike association and users. First, an evaluation criteria system consisting of sixteen criteria obtained from the five dimensions of tangibles, reliability, responsiveness, assurance and empathy is constructed based on a revised service performance model. Thereafter, a hybrid multi-criteria decision-making model that combines Decision-Making Trial and Evaluation Laboratory (DEMATEL) with VIsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is proposed. Then, the model is applied to evaluate the service quality of bike sharing in Xi’an City. Finally, some useful suggestions are given to improve the bike sharing service quality from the perspective of multi-stakeholders.     

Air Pollution and ‘Dirty’ Industries: How and Why Does the Composition of Manufacturing Output Change with Economic Development?

This paper examines the impact on air pollution ofchanges in the composition of manufacturing output indeveloped and developing countries. Pollutionemissions from manufacturing output are estimated ina manner which holds constant the effect of technologyand regulations allowing the impact of compositional changes alone on pollution to beestimated. The paper has three main findings; (1) theinverted-U estimated between per capita income and thepollution intensity of GDP arises due to both thecomposition of manufacturing becoming cleaner and theshare of manufacturing output in GDP falling.Compositional changes alone are not responsible forthe inverted-U between per capita income and percapita emissions; (2) changes to the composition ofmanufacturing output are consistent with the pollutionhaven hypothesis, however there is clear evidence thatrising per capita incomes are associated with afalling income elasticity of demand for `dirty'products. This fact may explain the compositionalchanges that occur with development; (3) in additionto the income elasticity effect, the analysis suggeststhat land prices and to a lesser extent the prices oflabour and capital, determine the proportion of dirtyindustry within a country's manufacturing sector.

安徽省全域旅游发展研究——基于空间杜宾模型

基于2007-2016年面板数据,采用空间杜宾模型对安徽省16个城市的旅游业全要素生产率及空间溢出效应进行了实证分析。研究结论表明:安徽省旅游业存在显著的空间相关性,且安徽省各市旅游业表现出“低值-低值”到“高值-高值”的集聚特征转变趋势,安徽省各市旅游业的间接溢出效应不显著,经济发展水平、区位熵和交通通达度的直接溢出效应和总体溢出效应显著。
