Multinomial Logit Model has analyzed the relationship between the frequency of visits to recreation areas and the motivational factors affecting the visits. Kastro Environment Preserving Site that is located in the Black Sea coast of Marmara region in Turkey, has been chosen as the site for this study. Kastro bay is a natural park that is visited only for recreational visits. The study has been conducted on a photogenic study group due to the proximity factor of Kastro bay close to Istanbul. Kastro bay is a popular recreational park due to its characteristic advantages such as a 200 m wide and approximately 2.5 km long beach and with its high quality vegetation. The vegetation type includes ash tree, oak tree, black pine, sand lily etc. Kastro bay is also the site for the Mediterranean seals (Monachus-monachus) which are at the level of extinction. Approximately 50,000 visitors visit the region during the months of July and August. It has been concluded that there is high direct correlation between the frequency of visits and the motivational factors. It has been determined that the visits are mostly based on the sea and the ecological tourism.Jel: O13, Q20, Q26, Q51, Q56, Q57 相似文献

企业技术能力的演进是一个技术学习过程,本文对技术能力和技术学习的基本内涵进行了分析和探讨,并提出了一个企业技术能力发展决定因素和机制的分析框架。我们认为,为获取技术能力发展所需要的知识和技能,技术学习需要整合三个维度的知识学习:个人学习与组织学习,内部知识学习与外部知识学习,以及显性知识与隐性知识的学习。因此,企业技术学习应该包含以下四个子过程:外部知识获取、内部知识获取、知识编码化以及知识社会化。由于这四个过程所获取的知识来源,性质不同,为完成这些子过程所需要的资源和机制也各不相同。通过对各个子学习过程决定因素和机制的分析识别,综合起来,我们为分析企业技术能力获取的决定因素和内部机制提供了一个基本理论框架。 相似文献

In this article, we demonstrate by simulations that rich imputation models for incomplete longitudinal datasets produce more calibrated estimates in terms of reduced bias and higher coverage rates without duly deflating the efficiency. We argue that the use of supplementary variables that are thought to be potential causes or correlates of missingness or outcomes in the imputation process may lead to better inferential results in comparison to simpler imputation models. The liberal use of these variables is recommended as opposed to the conservative strategy. 相似文献

The modified logit model (Amemiya and Nold, 1975) is generalised to the case where the error term is autocorrelated. The
asymptotic distribution (as n →∞ and T →∞) of a feasible GLS estimator of β is derived. Tests of linear restrictions on β and the significance of ρ are presented.
The results of the applied work suggest that the factors which explain the pricing behaviour of manufacturing firms, as reported
in the tendency survey conducted by the Australian Chamber of Commerce and Industry and the Westpac Banking Corporation, include
historical inflation rates of up to 7 quarters and capacity utilisation.

Evolution of trade patterns in the new EU member states 总被引:5,自引:0,他引:5
Andrea Zaghini 《Economics of Transition》2005,13(4):629-658
The paper analyses the evolution of the trade specialization pattern in the new EU member states. Relying on the empirical approach of the Markov transition matrices it analyses both the changes in the external shape of the distribution of comparative advantages and the intra‐distribution dynamics. The new members show a dynamic trade pattern: they gained comparative advantages relatively fast in sectors in which they were lagging behind at the beginning of the transition, notably in some ‘high tech’ products. In addition, many specialization improvements occurred in those items for which world demand expanded at the fastest rate over the nineties. 相似文献
