Despite its contribution to the national economy, domestic tourism is one of the most neglected and under-researched forms of tourism in the literature. This study tested an integrated path model examining the interrelationships between destination image, perceived quality, satisfaction and behavioural intentions, using domestic tourists who visited Eilat, Israel. The findings support the hierarchical relationships between image, quality, satisfaction and behavioural intentions. In addition, the affective image component was found to exert a far greater impact on the overall destination image than the cognitive component. The study establishes a better understanding of domestic tourists’ destination image and behavioural intention formulation. It also provides a number of implications for destination managers targeting the voluminous domestic segment. 相似文献

THE RELATIONSHIP BETWEEN EXPORT STATUS AND PRODUCTIVITY IN SERVICES: A FIRM‐LEVEL ANALYSIS FOR SPAIN
Asier Minondo 《Bulletin of economic research》2014,66(Z1):S138-S146
This paper analyses the relationship between export status and productivity in a major service exporter, Spain, during 2001–07. I find that exporters in the services sector are 45 percent more productive than non‐exporters. This productivity premium is larger for firms that supply non‐internet‐related services than for firms that supply internet‐related services. The results show that exporters were more productive than non‐exporters before beginning to export, and also that exporting increases productivity growth; however, this positive shock vanishes quickly. 相似文献

Market characteristics, including intrinsic demand and customer sensitivity on price and product performance level, are distinct at different markets. Comparisons of various product development strategies in one market or two geographically separated markets are conducted for three classes of products: development intensive products (DIPs) with constant unit cost, marginal cost-intensive products (MIPs) with constant fixed cost, and marginal and development intensive products (MDIPs) with non-constant unit cost and fixed cost. Results show that larger demand size, less customer sensitivity on price and/or more sensitivity on performance level lead to more profit, a higher sale price and a not-lower product performance. The customer reservation or the saturation performance level should be generally adopted though the optimal performance level does exist occasionally. Unit cost and/or fixed cost must increase in performance at an increasing rate for the existence of one optimal performance level. Due to the impact of demand size, one high-end (low-end) MDIP or DIP could be introduced into one low-end (high-end) market at a different price if the demand size is significantly large in the low-end market. For DIPs, offering one niche high-end product is not worse than offering the low-end product into two markets. For MIPs with negligible fixed cost, the product line strategy is not worse than the standard product development strategy. Additionally, the product cost reduction approach adopted in one product line has significant effects on the best product development strategy and sequence. 相似文献

Although supplier selection in multi-service outsourcing is a very important decision problem, research concerning this issue is still relatively scarce. This paper proposes a decision method for selecting a pool of suppliers for the provision of different service process/product elements. It pioneers the use of collaborative utility between partner firms for supplier selection. A multi-objective model is built to select desired suppliers. This model is proved to be NP-hard, so we develop a multi-objective algorithm based on Tabu search for solving it. We then use an example to show the applicability of the proposed model and algorithm. Extensive computational experiments are also conducted to further test the performance of the proposed algorithm. 相似文献
