While the tourism sector shifts towards digital transformation, Destination Management Organisations (DMOs) often struggle to adapt to their changing technological environment. This study explores the antecedents of digital collaboration and develops a framework for micro-DMOs to enhance effective destination management through digital technologies. An integrated sequential qualitative approach was adopted by conducting multi-phase interviews, in addition to designing and trialling a real-world trial digital platform. The research provides empirical evidence that digital collaboration is essential for micro-DMOs, necessitating them to transform their current “websites” into digital platforms which act as a hub for business stakeholders to actively be involved in. Antecedents of successful digital collaboration include mutuality, trust, control, and leadership which may be manifested differently from non-digital collaboration. Additionally, the study identifies three aspects for digital collaboration; marketing, networking and knowledge sharing that demands specific attention. Our results have theoretical, methodological, and practical implications for academia, industry and policymakers.  相似文献

Drawing on the information system success model and perceived value theory, we develop a research model to examine factors that may affect user satisfaction and loyalty of mobile payment platforms. Empirical data was collected from users using Alipay and WeChat Pay in China, and a total of 410 valid responses were gathered for data analysis. The results show that the multi-dimensional formative perceived value including benefits and sacrifice is important determinant of mobile payment user satisfaction and loyalty. The three benefit dimensions of functional value, experiential value and social value are more important value components than the two sacrifice dimensions of risk and cost, and experiential value is the dominant component of mobile payment users' value perception. As for the antecedents of perceived value, system quality and service quality mainly affect perceived benefits, while information quality has a greater impact on risk. The research results provide the contribution of specific value dimensions to users' perceived value and the impact of quality characteristics on specific perceived value for mobile payment platform providers, thus helping them to adopt effective strategies to strengthen market competitiveness and retain existing users.  相似文献

Research Question/Issue: This study, in the taxonomy of Schiehll and Martins (2016 Schiehll, E. and H. C. Martins. 2016. Cross-national governance research: A systematic review and assessment. Corporate Governance: An International Review 24 (3):18199. doi:10.1111/corg.12158.[Crossref], [Web of Science ®] [Google Scholar]), examines cross-national corporate governance, within their “legal” category. It rests on the understanding that to fully grasp corporate governance it is essential to understand the embedded institutions. The research question is: Does an increase in legal quality cause an associated increase in the quality of corporate governance in the form of financial reports to investors? If so, this supports the fundamental importance of legal systems to earnings quality. Reliable evidence on whether there is an association between legal quality and financial reporting quality would be an empirical association showing that where legal quality is higher, earnings quality is also higher, and conversely.

Research Findings/Insights: The results show clearly that in 2005 and 2010, when adequate data are available for testing, earnings quality is poor: far more companies show small gains than small losses. A great deal of managerial discretion is exercised in arriving at accounting figures, since many amounts depend on forecasts of future events. A significant number of firms use that latitude to show positive earnings. As to patterns of earnings management among three clusters of countries, the small number of firms generally precludes strong statistically supported evidence of management within the clusters. Nevertheless, the whole is the sum of the parts, and the parts (clusters) indicate the clusters most responsible for the overall result. There is little evidence of small gains exceeding small losses in the Baltics, greater differences in the Visegrád countries, and big differences in southern Europe.

Theoretical/Academic Implications: Based on both (a) the historical background of legal systems and (b) attitudes concerning legal quality measured at the same time as the earnings measures, the accounting results are consistent with the prediction of a strong legal culture driving effective corporate governance.

Practitioner/Policy Implications: The results show that eastern firms, on aggregate, have yet to reach the level of their western counterparts. However, the differences do not seem highly significant, and indicate that convergence is close in this area. This, in turn, should guide and encourage legislators in their work.  相似文献

Models of cities based on conventional spatial market theory are unable to replicate a realistic size distribution. The stochastic process approach to size distribution, which assumes proportionate growth, does not provide an economic foundation for spatial trades. There is an apparent irreconcilability. We propose that since there is a continuum of equilibria in models of spatial markets with endogenous location, proportionate growth can work as equilibrium selection. We present computations for an urban configuration that has not been presented in the literature before. A small city locates inside a larger city's agricultural supply zone. This generates a larger variation in city size that may include a realistic size distribution.  相似文献

In implementing its national strategy to achieve global leadership, China needs a new public administration theory that integrates political administration, economic management and social regulation. Even so, China has already started to promote its brand of political and economic development abroad. Therefore new comparative research and dialogue is called to explore the universality of Chinese and Western public administration ideas.  相似文献

研究目的:阐明"三权"分置的制度逻辑,为制度供给的增量调整提供一种思路。研究方法:文献分析法、政策文本分析法。研究结果:当下农民、新型农业经营者出现新的制度诉求,既有土地承包经权营制度不足以满足该需求。承包地制度供给创新要做实承包权,辨明"三权"分置下经营权所处的位置。土地经营权的权利塑造过程应坚持物债二分法,实现物权法、合同法双重法制途径的并重。研究结论:承包地"三权"分置本质上是理论创新问题,辨清"三权"分置的制度逻辑,仍需以实践需求为出发点,新的制度供给是一个增量调整与立法跟进问题。对经营权性质的探讨有必要融入物债二分逻辑,对于短期限的土地经营权,应按照契约自由原则,实行意思主义,权利类型、权利内容经双方自由创设,对长期存续的土地经营权可实现物权化,实行物权法定主义,按照法定规格与程序流转。  相似文献
