Drawing on institutional theory and innovation literature, we argue that greater regulatory and normative pressures concerning environmental issues positively influence companies' propensity to engage in environmental innovation. Analysis of environment‐related patents of 326 publicly traded firms from polluting industries in the United States suggests that institutional pressures can trigger such innovation, especially in those firms displaying a greater deficiency gap (i.e., firms polluting relatively more than their industry peers). Moreover, we find that this effect is stronger when asset specificity is high, and that the availability of resources plays different roles depending on the type of pressures (regulatory vs. normative).Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Empirical work on the acceptance of environmental impacts and responsibilities by hotels in developing countries is still relatively rare. There is also little work on understanding the relationship between business and environment among small and medium hotel companies. This research helps fill the knowledge gap by providing information on the responsiveness of small and medium hotels towards environmental management within the context of Kuala Lumpur, Malaysia, It explores the awareness and attitudes of small and medium hotel managers towards environmental management and their opinion on how things can be improved. Questionnaires containing Likert scale questions, supplemented by open-ended questions, were personally administered to willing participants. The findings indicate that respondents generally tend to provide positive response to the Likert scale questions, but refused or were unable to give clear answers to the open-ended questions which were designed to explore further the answers they provided. In practice, managers also did not go beyond the basic common sense of cutting their water and energy costs. These indicate a lack of clear and adequate knowledge about environmental management, and their tendency to be “politically correct” in relation to environmental issues. The paper ends with recommendations on how to improve the environmental management knowledge and know-how among managers of small and medium hotels.  相似文献

Sustainable tourism aims to achieve a balance between the needs of tourists, the environment, local people, and businesses – a situation complicated by the numerous ethical issues at play. This paper presents an original account of the ethics of Aldo Leopold (1887–1948), a key figure in the development of modern environmental ethics, as it unfolds in his classic work, A Sand County Almanac. We argue that prior interpretations failed to incorporate Leopold's lynchpin cultural harvest idea into his larger “land ethic”, and that a proper understanding of the cultural harvest reveals how tourism and other recreational activities can drive a person's ethical development. Ultimately, the land ethic helps us protect and nurture the most precious sustainability resource: human beings that value and respect the environment. The paper will be of value to tourism scholars, to heritage interpreters, to travel journalists, to tourism marketing staff, and to tourism managers. It shows the enormous opportunities for better marketing and heritage interpretation, notes the potential value of slow tourism, and the need for opening five key areas of the cultural harvest for tourists: storytelling, learning and knowledge, beauty and aesthetic appreciation, rarity and the hunt for trophy, and signature/personality.  相似文献

Food justice, food cultures and people's engagement with healthy food production and consumption are key contemporary concerns, with a growing sustainable hospitality and tourism literature. Efforts range from narrowly focused initiatives, such as promoting organic produce and fair trade, to more holistic challenges to current systems through initiatives like the slow food and locavore movements, which may represent systemic alternatives. However, little analysis is available on how cafés and restaurants might become sites for experimentation in profitable and just sustainable hospitality, and places for sustainability engagement and education. Focusing on the evolution of a sustainable café in Adelaide, South Australia, this article explores how one entrepreneurial restaurateur uses his café to engage customers and community in a collaborative conversation about sustainable development, food, hospitality and tourism, helping transform our food culture and even lifeways. Our findings indicate the value of deep local embedding as a pathway to meaningful sustainability. The study offers insights into how hospitality and tourism can contribute to dialogues on alternative consumption which may offer visionary pathways to alternative futures. It also explores the role of pioneers in sustainable business and hospitality, their drivers and their views. A forthcoming global research initiative is discussed.  相似文献

Some tourist farms established in the Chinese province of Guangdong suffer from a dearth of farm management and a lack of awareness of environmental protection issues among visitors, leading to pollution problems in farm tourism. The study reported in this paper examined how the managers of two farms protect the natural environment using the setting factors of physical orientation, interactive exhibits and the presence of tour guides, following the mindfulness and mindlessness model. The findings of the study revealed that the quality of the natural environment in both farms was acceptable, indicating the effectiveness of the setting factors. However, it was found that some signs were discolored and broken, there were insufficient interactive exhibits, and no tour guide service was available for individual visitors. Based on these findings, some recommendations are offered for farm managers on how to protect the natural environment.  相似文献

Ecotourism training is usually considered to be undertaken only by tourism practitioners for professional development. However, ecotourism training has a more important role to play, as it could be adopted as a long-term strategy for environmental conservation by altering people's attitudes and behaviours towards greater environmental responsibility. In this study, the role of ecotourism training with respect to pro-environmental knowledge enhancement as well as attitude and behavioural changes is investigated. A questionnaire survey was conducted on participants of an ecotourism training programme. Participants' environmental knowledge, attitudes and behaviours were evaluated using a pre- and post-test method. The results indicated that participants demonstrated a significant increase in environmental knowledge after the training. Moreover, participants' demographic characteristics such as age group, occupation and salary are significantly associated with the improvement in knowledge, change in pro-environmental attitudes and behaviours. Participants tend to adopt environmentally responsible attitudes and behaviours after completion of ecotourism training.  相似文献

The success of tourism firms relies heavily on their ability to adapt to the changing external environments. Environmental scanning, as the acquisition and use of information about external events and trends, has received greater attention in the tourism management literature. This study investigated the environmental scanning initiatives of travel agent companies in Singapore through a questionnaire survey. In total, 42 completed forms were returned from 319 invited firms. The findings discovered a positive relationship between the scanning frequency and the perceived strategic uncertainty of task environment. It was also found that human information sources were used most frequently for collecting environmental information due to their highest reliability, while electronic sources were under-utilized probably due to lack of computer-based information system and awareness toward the importance of online information.  相似文献

This article examines urban residents' perceptions of environmental impacts in the city of Pigeon Forge, Tennessee. The study vies to contribute to knowledge concerning how citizens in Tennessee view tourism and its impact on the environment. A mail survey was administered to 400 registered voters. Factor analysis, Cramer's V statistical measures of association, chi-square tests, and Spearman correlation coefficients were employed for the analysis and interpretation of the data. Tests and associations support three hypotheses; residents' perceptions of the impact of tourism are influenced by employment status and short-term residency. Greater lengths of residency, age, and annual income do not influence residents' perceptions.  相似文献

This research examines two modes of assessment of environmental health risks and the transformation of these risks into public health issues while relying on the specific case of well‐water toxicity and mega dose of electromagnetic radiation found in one prosperous town in the center of Israel – Ramat ha‐Sharon. Based on official and scientific documentation and interviews conducted at three time periods with randomly selected town residents from contaminated neighborhoods (N = 169), this study shows the discrepancy between the ‘objective’ experts’ standards for assessing environmental health risks and the public’s subjective perception and evaluation of the impact of these risks on their health and well‐being. Even though, by experts’ standards, the well‐water toxicity remained constant over the three interview sessions, Ramat ha‐Sharon town residents’ subjective levels of concern and perception of risk fluctuated as a function of news media and municipality announcements and residents’ perceived ability to minimize the risk. This study also shows the complex and multidisciplinary nature of environmental health risk assessments and the need to relocate them into the broader socioeconomic and political context in which they are embedded.  相似文献
