Humanities and social science have fuzzy boundaries due to the application of findings from natural science and technologies. But their core features are associated with the social and humanity aspects. And the independent value of research on humanities and social science lies in the description of objects in neutral and objective perspectives, in discoveries of relationships and predictions of tendencies, as well as in the contribution of managerial suggestions. Any kind of knowledge accumulation, proposal of analytical structures or logical constructions, methods and technologies that will facilitate the achievement of one or several of the above-mentioned fundamental goals are the important content of scientific research and innovations. Interdisciplinary research is gaining rapid popularity at home and abroad, and the number of application-orientated interdisciplinary subjects and studies is ever increasing. The interdisciplinary concept frequently occurs from various meetings to diverse policies, from project proposals to award reviews, and from curricular design to the establishment of a major. However, in contrast to discourse focus interdisciplinary research has not yet become productive. And interdisciplinary science remains no more than a lexical focus at the conceptual level, whose characteristics, regularities and ontology have drawn little attention. Moreover, the talents and supporting funding in interdisciplinary research as well as their social influence are still in a disadvantageous situation. The study of tourism is an investigation of complex phenomena that are closely related to society, nature, culture, economy and environment. With the increment of the number of tourists and the expansion of tourism economy worldwide, the development, organization, management and the social effect of tourism research is drawing increasing attention, and the targets of tourism research is becoming more and more diverse, accordingly the paradigm of tourism research exhibits a vast variety. However, at present the social influence of tourism research is relatively weak, far behind that of the tourism industry, especially in terms of the description of emerging tourism economy, tourism effects, and the development and change of tourist behaviors, which are still stuck in difficult situations of scientific research. This paper takes tourism research as an example to discuss strategies to achieve breakthroughs in interdisciplinary cross studies on humanities and social science. It suggests that emerging interdisciplinary research focus on the construction of fundamental concepts, classification and statistics, meanwhile, it pay attention to the formation of open growing frameworks of knowledge that can accommodate the development of emerging phenomena, to the extension of corpus data collection and various analytical methods, the encouragement of basic investigation and description of emerging phenomena, the guidance of scientific research towards social demands, and to the popularization of scientific research findings, in order to promote substantial innovations of scientific research on the basis of paradigmatic boundaries.
