As a strategic pillar industry of the national economy，tourism has been actively integrated with other industries in recent years，expanding in scale and with the emergence of a large number of new business models，effectively contributing to the smooth running of the national economy. The tourism industry has rapidly expanded from sightseeing to a series of related industries such as tourism catering，tourism accommodation，cultural experience and cultural and creative design. The rapid development of the tourism industry has also exposed the lack of relevant legislation，including outdated legislative concepts，simple categories，lack of features and other key factors that restrict the healthy and orderly development of the industry. Taking Jiangsu province as an example，we analyse the content，quantity and categories of local tourism legislation at the provincial level and in the municipalities by using word frequency analysis and other means，and find that there are problems of lagging legislative concepts，lack of coordination and lack of distinctive features between provincial and municipal tourism legislation，and propose an optimization path for local tourism legislation in three aspects：conceptualization，precision and distinctiveness.
