技术性贸易壁垒对中国出口贸易的影响从长期来看是正向效应,它是技术进步的阶梯,促进了中国技术进步,增强了产品竞争力。因此,中国出口产品在遭受国外技术性贸易壁垒时,我们既要妥善处理好技术壁垒带来的短期负面影响,更要看到其长期的正面效应。  相似文献

Akamatsu, Sato, and Nguyen (2006 Akamatsu, T., Sato, S., &; Nguyen, X. L. (2006). Tradable time-of-day bottleneck permits for morning commuters (in Japanese). JSCE Journal of Infrastructure Planning 62(4), 605620.[Crossref] [Google Scholar]) proposed a first-best pricing scheme based on the concept of bottleneck permits. The scheme allows permit holders to pass a bottleneck at specified times and is shown to be able to minimize social cost. However, the scheme is not always Pareto-improving in that it may harm some drivers. The objective of this study is to design Pareto-improving pricing scheme with bottleneck permits for a V-shaped two-to-one merge bottleneck. First, the paper formulates the morning commute model in the network and describes the arrival time choice equilibrium in the network with merging bottleneck. Secondly, we show that the first-best pricing scheme with bottleneck permits for this V-shaped network does not always achieve a Pareto improvement, with the cost of one group of drivers is increased by the permit pricing, a phenomena akin to the bottleneck paradox of Arnott, de Palma, and Lindsey (1993 Arnott, R., de Palma, A., &; Lindsey, R. (1993). Properties of dynamic traffic equilibrium involving bottlenecks, including a paradox and metering. Transportation Science 27(2), 148160.[Crossref], [Web of Science ®] [Google Scholar]). We propose three implementations of bottleneck permits for Pareto-improving: (1) merging priority rule is included in the bottleneck permits scheme by creating different market for each origin; (2) the permit revenues are refunded as monetary compensation to drivers whose cost is increased; and (3) the permit revenues are used to expand bottleneck capacity. For each implementation, we derive their equilibrium solutions and demonstrate that the Pareto improvement is achieved and social cost is decreased by using the permit revenues for expanding the bottleneck capacity.  相似文献

中国省域森林公园技术效率测算与分析   总被引:5,自引:0,他引:5  
文章借助数据包络分析方法(DEA),利用2003~2008年的数据,对我国森林公园发展的效率进行研究,为我国森林公园旅游资源的优化配置和运行效率的提高提供参考依据,并测算了31个省区的技术效率、纯技术效率和规模效率,比较了它们之间的差异。结果显示,从全国来看,森林公园的技术效率较高;从个体来看,不同省区森林公园的技术效率存在较大的差异,上海、浙江、广西、广东等省区的技术效率较高;宁夏、内蒙古、安徽等省区的技术效率较低。通过优化投入规模与结构、人员培训等措施能够在一定程度上提高我国森林公园整体的技术效率。  相似文献

用地理集中指数衡量游客集中程度方法的一个改进   总被引:5,自引:0,他引:5  
朱沁夫  李昭  杨樨 《旅游学刊》2011,26(4):26-29
地理集中指数用来衡量游客集中度存在着一些不足,其大小受到样本数量多少的影响,既没有一个衡量的标准,又不能进行不同样本数量的结果的比较,且不够直观。考虑引入完全均匀分布的地理集中指数,并计算其与地理集中指数之差,再运用这个差值与完全平均的地理集中指数之比来衡量游客集中度,并称这个比值为游客集中度系数,这一系数可以较科学、直观地反映游客集中程度。  相似文献

This study uses the Malmquist index with bias correction to analyze the performance of hotel chains from the UAE, Saudi Arabia and Oman. We show that Saudi Arabia hotel chains have the highest productivity growth, followed by the UAE and Omani hotel chains. A further decomposition of productivity indicates that a small number of hotel chains experienced an increase in revenues for lower occupancy rate, while most other hotel chains experienced an increase in occupancy rate for lower revenues. Related market discussions of the results are provided.  相似文献

The first in this series of articles left Scotland on the verge of agrarian transformation. Although the nation geographically nearest to England, it remained in 1745 considerably more distant in social structure. England was the first state unambiguously to complete the transition from feudal to capitalist agriculture. Unlike England, however, those that followed did not have a period of several centuries in which to undertake the process. Lenin identified the alternatives that they faced as the Prussian 'reformist' and American 'revolutionary' paths. Scotland was to prefigure the Prussian path, where the feudal landowners themselves instigated the transition to capitalism in the countryside. After the final defeat of Jacobitism at Culloden in 1746, the Scottish feudal landowners were juridically stripped of the powers (military tenures, local jurisdictions) with which a section of them had threatened the British state. They were, however, allowed to retain most of their power over their tenants. With no remaining alternative but to adapt to the capitalist mode of production, they systematically used these powers to reorganize their estates along existing English lines. The speed and extent of the transformation that followed remains unprecedented in Western European history.  相似文献

The Hungarian economy was based on central planning for several decades and in comparison with the dominance of the great organizations that consisted of many smaller units, the role of small-sized enterprises was marginal. The change in the political climate involved recognition of and belief in entrepreneurship and the new legal system increased the opportunity for setting up new enterprises established on private and joint capital. Nevertheless, the changes in the organizational system of companies within the national economy appear to concentrate in time and territory in Northern Hungary. Increasing unemployment inspires the start of numerous enterprises even when the experience of entrepreneurship is missing and, in addition, the inclination towards it. This may result in difficulties and danger and a study of North Hungarian small businesses is therefore useful.

The aim of this research is to examine the position of SMEs in the North Hungarian industrial area, concentrating on questions that can not be answered by means of traditional statistics. Data were collected by surveying questionnaires. The questions referred to the development of SMEs in North Hungary.

Finally, the elements in the economic environment that may hinder or help successful operation of the enterprises were analysed. With the experience gained by our investigation we would like to help in the reinforcement of SMEs working in Northern Hungary.  相似文献
