经济增长通常意味着贫困率的下降,然而,对于增长很慢的经济体或经济增长没有带动贫困率降低的案例,这种假设似乎并不成立.中国两个较为贫困省份的数据展示了这样一个谜题:贵州省的经济增长缓慢但农村贫困率的下降较为显著,对这一现象不妨称之为"贵州新现象";与此同时,云南省经济高速增长但贫困率下降较为迟缓.根据相关考察和统计数据的分析,交通、流动人口、旅游业和矿产业四个因素是解释这个谜题的关键.这四个因素在两个省的不同分布和构造解释了它们经济增长与贫困率下降关系中的不平衡性. 相似文献

This study aims to understand self-drive tourists’ satisfaction with and loyalty toward scenic roads. Building on previous studies in the context of tourism destinations, satisfaction is hypothesised to be influenced by leisure and holiday motorists’ motivation for driving the routes and the provision of roadside facilities. In turn, satisfaction is assumed to increase motorists’ loyalty toward the route. The study comprises data from two scenic roads in Norway that differ with respect to landscapes formations, settlements, experiences along the routes, and travel distance. Data are analysed using structural equation modelling. Results show that roadside facilities play a crucial role in achieving overall satisfaction and loyalty among motor tourists, and that route managers should improve the quality of these and related infrastructure facilities and services. Moreover, the study indicates that it is important to take into consideration the motorists’ desire to experience attractive sceneries in order to increase overall route satisfaction. Finally, satisfaction is demonstrated to significantly increase route loyalty, although this relationship appears weaker than in conventional destination studies. 相似文献

This paper investigates the risk perceptions of key stakeholder groups typically involved in public–private partnership (PPP) toll roads. Risk perceptions have an important impact on these PPP schemes for investing in public infrastructure. However, the nature and extent of risk associated with the specification of a PPP contract that commits contracting parties to deliver on their obligations remain unclear. In the context of major transport infrastructure, such as a new toll road, the often‐cited key risk to investors is the traffic (and hence demand) risk. There are, however, other risks, including political risk and media risk, the latter often causing untold harm resulting in modifications to the planned infrastructure. This paper develops a method to capture evidence on how public sector and private sector partners involved in previous PPPs perceive the levels of risk associated with each risk attribute, as a way of identifying the ex ante risk setting brought to negotiations in PPP toll road investments. Using a sample of 101 experts with contract experience in 32 countries, we develop a stated choice experiment and estimate a discrete choice model to quantify a risk profile index (RPI) to capture the perceived (relative) influence of each dimension of risk, and then identify sources of systematic differences in the RPI as a way of understanding the influence of personal traits and contextual and contractual factors. 相似文献
