农村养老保险规定和完善着公共财政的职能范围;公共财政是农村养老保险的制度依托和物质基础,财政主体的权力结构、制度的包容性、法制化决定着养老保险制度的可持续性发展。我国要实现公共财政与农村养老保险之间的制度性耦合,需要根据农村养老保险的产品属性清晰界定公共财政的职责权限,规范公共财政各主体之间的权力资源配置,吸纳多元主体,共同参与农村养老保险事业的建设。  相似文献

本文从公共物品的性质、分类等基本理论出发,对政府垄断公共物品供给存在的问题、公共物品市场化供给可能性、内在依据及条件等进行了理论分析,并通过构建公共物品供给的委托代理模型,分析政府在市场化过程中政府的职责和作用,提出充分利用市场机制改革政府提供公共物品的方式,是解决公共物品有效供给的必由之路,并围绕基础设施阐述适合我国基础设施市场化的几种项目融资方式。同时,本文以绍兴市的基础设施市场化建设为例,分析了绍兴市城市基础设施的主要做法,并从绍兴市的市场化实践中得出有益的启示,从政策上和措施上对如何利用市场机制、完善我国公共物品供给进行了探讨。  相似文献

In Norway, as in many countries, there is a political goal to increase bicycle use. The electric bicycle (e-bike) is a promising tool for achieving this goal, given the hilliness of the country. However, little is yet known about the deterrents of cycling in Norway in general, and in particular how the purchase of an e-bike could be stimulated.

In the current study, 5500 respondents from a convenience sample among car owners were asked about their perceptions of bicycling in general, and of e-bikes in particular as well as their willingness to pay (WTP) for an e-bike. Randomly selected participants (N = 66) were given access to an e-bike for a limited time (2 or 4 weeks). A second questionnaire captured the same perceptions and WTP post-intervention. The results were compared with a control group (N = 214).

The results showed that those who cycle the least were most interested in buying an e-bike and that prior knowledge of the e-bike corresponded with a higher desire to buy one. Pro-environmental values did not predict interest in e-bikes, neither did norms and attitudes toward cycling. The WTP for an e-bike increased after having experienced the benefits for those who used an e-bike compared to those who did not. Price reduction of the e-bike (e.g. VAT exemption), spread of knowledge among the wider population, and actions to offer an e-bike experience may therefore be effective strategies for further expansion of the e-bike in the transport system and thereby to increase bicycle use in Norway.  相似文献

Freight on Transit (FOT) refers to an operational strategy where public transit vehicles and/or infrastructure are used to move freight. Examples include moving goods alongside passengers on buses, attaching cargo trailers to transit vehicles, and operating freight vehicles between trains on subway lines. This paper describes the methods and results of a three-round Delphi study engaging 34 transportation experts to explore challenges and opportunities of FOT and to conceptualize and evaluate potential FOT operations in Toronto. Traditional Delphi methods were used for the exploration of FOT challenges and opportunities, and a modified approach was formulated to integrate experts' opinions and develop new FOT concepts for Toronto. The results support previous claims that technical challenges of FOT may be easier to overcome than institutional barriers. Evaluation of potential FOT operating strategies in Toronto suggests that while the current public transit network does not have capacity to support additional movements, there may be realistic opportunities to include freight service in future projects as a means of offsetting operating costs and reducing the impacts of goods movements.  相似文献

互联网对旅游目的地分销渠道影响——黄山案例研究   总被引:5,自引:0,他引:5  
张朝枝  游旺 《旅游学刊》2012,27(3):52-59
互联网的发展与应用对旅游目的地分销渠道产生了显著影响,传统旅行社的分销渠道功能发生变化,一些新的分销渠道如黄山的自助游服务酒店开始出现。关于互联网是否导致旅游分销渠道的"去中介化"和"再中介化"的争论成为学术界讨论的热点。文章以黄山为案例,以历时态的视角动态分析了互联网对黄山旅游目的地分销渠道的影响。研究发现,互联网使旅游目的地分销渠道更加多元化、网络化,目的地旅游分销关系、功能与结构等方面也发生了相应的变化,旅游者的主导地位增强,旅游中介的垄断地位相对减弱,但目的地的分销渠道"去中介化"与"再中介化"并未清晰地形成。  相似文献

Owing to a lack of construct reliability and validity of environmental management measurements, advancements in understanding hotels’ environmental management practices have been somewhat limited. The goal of this paper is to propose a uniform and parsimonious scale that captures Hotels’ Environmental Management Initiative (HEMI) with the most common three dimensions in the hotel industry: environmental resource conservation efforts, environmental policy and training, and environmental public relation efforts. After the refinement of the initial items, the scale was confirmed with cross-cultural data obtained from full-time hotel employees in two Asian countries. The twenty-one item HEMI scale demonstrated a satisfactory level of content, convergent, discriminant, cross, and criterion-related validity. The proposed HEMI scale will serve as a useful tool for future hospitality scholars who would like to further explore the impact of hotels’ environmental management initiatives on employees’ attitudes and behaviors toward the environment and their environmental performance.  相似文献
