Taking the urban tourism of Guangdong, Hong Kong and Macao as an example, it aims at presenting a new spatial system of urban tourism research and pointing out the new orientation of urban tourism research in combination of macro level and micro level, from description to explanation. The meanings of the spatial framework construction for urban tourism study are to make clear how urban tourism studies vary with the changes of dimensions of time and space. This is a meaningful discussion because it will bring great changes to the using of literatures, the opening of research perspectives on urban tourism and the upgrading of theories, so as to create a new stage for urban tourism study.展开更多

To this end, this paper will explain the meaning of intellectual capital （human capital, structural capital, and relational capital） in the field of knowledge economy and what relational capital is and how we can measure its value. The research is qualitative in nature and was developed through the study of the international literature. The research presents some theoretical evidences that permit defining a method for the evaluation of relational capital. In this direction, the above method will need to have some integration in the future research. Moreover, this approach should consider some empirical evidences to establish the practical value of the method. In fact, the method presented encourages debate and a critical attitude towards the evaluations of relational capital and intellectual capital.展开更多

文摘This paper tries to apply a new and more comprehensive method to urban tourism research in an expanded field instead of only partially, unilaterally and separately focusing on the city itself. Taking the urban tourism of Guangdong, Hong Kong and Macao as an example, it aims at presenting a new spatial system of urban tourism research and pointing out the new orientation of urban tourism research in combination of macro level and micro level, from description to explanation. The meanings of the spatial framework construction for urban tourism study are to make clear how urban tourism studies vary with the changes of dimensions of time and space. This is a meaningful discussion because it will bring great changes to the using of literatures, the opening of research perspectives on urban tourism and the upgrading of theories, so as to create a new stage for urban tourism study.
