Near Dahu, there are some attractions, such as hot springs, native Taiwan Residents tribes and a national park named Shei-pa. In order to better support more small businesses in this area, the local government is eager to promote an industrial cluster of agriculture and tourism based on the well-developed strawberry farms. In this research, the authors investigated 200 strawberry farmers to examine forming factors of the cluster, and effects of cluster on organizational performance. The findings are firstly, capital resource is regarded as the most effective forming factor of the cluster. Secondly, institutionalization, interaction mechanism and knowledge flow positively intermediate the clustering effects on organizational performance. These findings have important implications for the local government and the businesses as well.展开更多

Indeed they meet the need to implement techniques and management tools which are able to improve the culture-tourism binomial. This would permit to transform into valid instruments of national economical development, the shared declaration of intents for which culture and tourism, especially in Italy and in this particular fragile period, represent even more the main strategic levers for the sustainable development. This article intends to describe the potentiality of these widespread hotels as innovations particularly suitable with trends recently emerged in tourism sector and outline the phenomenon pattern in ltaly with particular attention on Umbria region, in order to identify his main strength and weakness and some innovation to improve performance. To this end, it starts from the analysis of the national and international economic-managerial literature concerning in particular cultural and experienced trends shown in tourism. Then it introduces the main acquisitions about widespread hotels in Italy, updating and extending them through a desk survey based on indirect sources of various natures. Lastly, it describes the case of Umbria, analyzing more in depth making use of interviews with entrepreneurs/managers of hotels and based on a semi-structured questionnaire. The aspects of indeterminateness which were found, starting from the normative one, testify how the potentiality of the widespread hotels as far as regards the value creation for the enterprise itself and the territorial stakeholder, are still not properly understood and therefore used. It is clear that, therefore, new behaviors are needed for entrepreneurs and, most importantly, for local policy makers in order to create the conditions for the full success of these hospitality models.展开更多
