Research on social capital within the leisure context has become an academic hotspot. This paper firstly reviews Putnam's classical research on leisure, voluntary organization, and social capital. Putnam (1993, 2000) highlighted the importance of social communication inside voluntary organizations in which the membership established and maintained larger social networks by uniting related strangers. Therefore, general trust and mutual relationships were produced, as well as the value of social cooperation. Nevertheless, some scholars criticized Putnam's view because the most significant difficulty in interpreting Putnam's argument lay in its detailed description and explanation of the influences of the system and the ways of social capital was established and maintained in voluntary organizations. To solve this difficulty, Hemingway (1999) attempted to identify the mutual relationships of leisure, social capital, and citizen democracy using interdisciplinary insights. He proved that the fundamental contribution of leisure is in its indirect effect on citizen democracy; that is, leisure and citizen democracy are related by social capital. Hemingway consequently pointed out that there are three approaches to combine the various analyses of leisure and social capital: first, he analyzed how different leisure forms mainly affect citizen democracy and social capital; secondly, he highlighted the need to acknowledge the necessary personal and social resources for the development of leisure social capital. He also outlined the structure and distribution of social capital so that it grows more equally. Thirdly, he focused on a study of the role of leisure in social capital. Based on Hemingway's three research methods for leisure and social capital as described above, we researched the previous ten years of literature in the foreign leisure field to identify related materials and papers. We found that current commentary on social capital in the foreign leisure context is explored using two aspects of research: research content and research approaches. In research content, the application of citizens' social capital and leisure social capital has shown great progress, with leisure taking a more significant role in the establishment of social capital while allowing social interaction processes to be fully realized. In research approaches, microcosmic resource and macrocosmic civic approaches were considered general and mature research perspectives in the leisure social capital research field. Microcosmic research approaches were mainly qualitative, and macrocosmic civic approaches were mainly quantitative and investigative. Specifically, these indices distinguished between the two types of approaches with significant differences, which reflects the wide gap between micro- and macrocosmic aspects in social capital research. We combined these micro- and macrocosmic approaches to shrink the gap by analyzing the role of social networks in social capital. Finally, we discuss our inspiration of combining foreign leisure and social capital research in the Chinese leisure and social capital research context. Our findings have significance for theory and in reality to advocate for a sustainable Chinese leisure social capital research, by referring to and using our advanced research results from comparing Chinese studies on citizen and resource approaches in the leisure context with similar and different origins of social capital in various leisure contexts around the world.
