客家乡村旅游发展时空演变及其动力机制研究

[目的]以客家核心区梅州市为例,探讨客家乡村旅游时空演变及其动力机制,以其为客家乡村旅游开发提供理论支持。[方法]运用计量地理法和GIS空间分析技术,从时间与空间两个维度上对客家乡村旅游时空演变及其动力机制进行分析。[结果]结果表明:时间维度上,客家乡村旅游发展阶段性特征鲜明,经历了萌芽、兴起和蓬勃发展3个阶段。空间维度上,客家乡村旅游点空间分布类型由均匀型向凝聚型演变,并呈集中分布,且随着时间的推移,集中程度呈现逐渐增大趋势。在此基础上探讨了影响客家乡村旅游时空演变的动力机制,其主要来源于外生和内生动力两方面;外生动力包括市场驱动力、政策驱动力和交通驱动力,内生动力包括资源驱动力、品牌驱动力和村落拯救驱动力。针对研究结果对客家乡村旅游发展从市场挖掘、政府支持和保护性开发等方面提出了相应的启示性建议。[结论]客家乡村旅游发展迅速,对其时空演变特征及动力机制的深入认识有利于进一步做好客家乡村旅游开发,促进客家乡村振兴。

Conducting qualitative and quantitative analyses of sustainable behaviour

Despite the efforts of academics, governments and industries, consumers do not have sufficient environmental education, attitudes and knowledge to change their behaviour. In terms of sustainable behaviour, most research has been focused on attitudes, while fewer studies have paid attention to and employed qualitative and quantitative analysis to sustainable behaviour investigation. This paper uses qualitative and quantitative analyses to explain sustainable behaviour and demonstrate the mutual relationships between environmental development, environmental impacts and sustainable behaviours. The results not only fill the gaps in the integration of qualitative and quantitative analyses of sustainable development but also provide theoretical and managerial implications for sustainable development in Taiwan.

Quantitative evaluation of sustainable development based on ecological footprint method: a case study of Tianjin

Since the concept of sustainable development emerged in the late 1980s, more and more countries and regions have been utilizing sustainable development as their developing strategy. But decades have passed without any effective methods available to quantitatively assess sustainable development, Since the ecological footprint evaluation method initiated in 1992, it has become popular in quantitative assessment of sustainable development because of its convenience, easy-understanding, and reliability. As one of the biggest coastal cities in north China and the economic center of the Bohai Coastal Region, Tianjin's gross domestic product (GDP) was 369.762 billion yuan in 2005, accounting for 2.0% of the whole nation's GDP The paper analyzes Tianjin's development with the ecological footprint method, and the results show that Tianjin's ecological footprint and biocapacity in 2005 were 2. 507gha/cap and 0.276gha/cap respectively. The ecological deficit was 2.230gha/cap. And from 1980 to 2005, Tianjin's ecological deficit per 104 yuan GDP decreased; while per capita ecological deficit has been tending to increase rapidly in recent years. All these results demonstrate that Tianjin is in a state of unsustainable development.     

Quantitative skills: is there an expectation gap between the education and practice of management accountants?

The extent to which management accountants are receiving appropriate training in quantitative methods is examined. It finds a disparity between the wide range of quantitative techniques covered within the Chartered Institute of Management Accountants' syllabi and the limited use made of many of the techniques in practice. It also reports a rich picture of differing expectations of the role of quantitative skills in the work of a management accountant. The study finds that quantitative skills are seen by both employers and accounting educators as contributing to the portfolio of skills required by management accountants. Also, they give a rigour to the examination process that is seen as a challenging ‘rite of passage’ into the profession. It is concluded that knowledge and understanding of the range of quantitative techniques available to organizations is a powerful differentiator for the accounting profession, even if the occasions upon which accountants are required to draw upon much of that knowledge are few and far between.     

Quantitative mapping of patented technology — The case of electrical conducting polymer nanocomposite

This study aims to obtain global technology evolution by constructing and analyzing patent citation network and patent citation map for the field of electrical conducting polymer nanocomposite. A total of 1421 patents are retrieved from USPTO patent database and patent citation network is established by combing both patent citation and social network analysis. Network properties, e.g. Degree Centrality, Betweenness Centrality, and Closeness Centrality, are calculated for representing several technology evolution mechanisms that first proposed in this study. Also, a distance-based patent citation map is constructed by calculating relative distances and positions of patents in the patent citation network. Quantitative ways of exploring technology evolution are investigated in this study to unveil important or emerging techniques as well as to demonstrate dynamics and visualization of technology evolutions.     

金融危机背景下美联储的非常规货币政策操作

面对金融危机，关联储不仅非常规地使用传统货币政策工具，而且还采取大量激进的非常规措施，通过购买各种证券向市场注入流动性以及运用信息沟通引导市场预期降低长期借贷成本的方式缓解金融市场紧缩局面。非常规货币政策是应对非常时期的非常措施，随着经济的复苏，各国经济刺激政策如何寻找安全退出路径是这一时期全球央行的主要任务。
