Visitor satisfaction is one of the most important indicators of the success of urban tourism development. However, mastering and controlling its influence is becoming more and more critical to urban tourism development and management. It is important for cities to increase the level of visitor satisfaction, improve urban tourism development, coordinate the relationship between urban development and urban tourism and enhance the sustainable development of urban tourism. According to the international literature, research on urban tourism in western countries originated in the mid-1960s, almost 20 years earlier than in China. The research content and themed have become richer and deeper in recent years, emphasizing concerns about urban heritage management and protection, urban tourism environments, business tourism and shopping tourism, theoretical framework development, the impacts of urban tourism, sustainability, and research progress. Although some research discusses the use satisfaction and production development in the context of international urban tourism, as well as visitors' perceptions of international cities, few studies have examined the most influential factors affecting tourists' satisfaction with urban tourism. In China, there are several shortcomings in the research on urban tourism. First, few scholars have undertaken quantitative analyses regarding the influence of, and relationship between visitors' satisfaction and urban characteristics, or visitors satisfaction and social demographics. Second, most literature on visitor satisfaction focuses on simple comparisons between expected and perceived experiences. Third, few, if any, have applied econometrics to test the causality between visitors' satisfaction, urban feature and demographics. Considering these deficiencies, document analysis, questionnaires and a Bivariate Discrete Probit Choice Model were used to test hypotheses about influential factors and visitor satisfaction. The influential factors were grouped into three main variables--urban features, personal characteristics and tourist motivation--and ten indicators. Data were collected from 477 visitors through an on-site survey in Changsha City. The results confirmed six hypotheses, and the modified visitor satisfaction-influenced Probit model exhibited statistical significance. The results indicate that the level of urban social development, degree of environmental protection, abundance of tourism resources, visitors' monthly salary, and positive visit motives have a positive effect on visitors' satisfaction. Among those variables, positive visit motives have the strongest influence, with the influence coefficient being 0.950122, while urban social development demonstrated the weakest influence, with the coefficient being 0. 205284. These findings raise concerns about urban development and quality of tourism. Finally, policy suggestions for city tourism managers are discussed, including improving systems of satisfaction, urban development and infrastructure, urban tourism resource development, and tourism marketing.
