As an important tourism resource, intangible cultural heritage has strong industrial driving benefits and social development value. Its spatial distribution imbalance and utilization status have theoretical and practical significance for the analysis of tourism development trend and tourism competition in related regions. In view of this, this paper uses GIS and tourism competition matrix method to analyze the case of Guizhou Province which is rich in intangible cultural heritage resources in 2019. The results show that: (1) the national and provincial intangible cultural heritage in Guizhou presents consistency and regularity in type structure, in which the number of folk intangible cultural heritage is the largest, while the number of folk art intangible cultural heritage is the least. (2) There are one high-density core areas and multiple secondary core areas in the space of national ICH in Guizhou Province. (3) Guizhou Province’s provincial intangible cultural heritage forms a belt density belt extending from southwest to southeast and three high-density core areas.(4) Through the analysis of tourism competition matrix, it is found that there are four development types in nine cities and states of Guizhou Province, namely “tourism prosperity-intangible cultural heritage tourism prosperity”, “tourism prosperity-intangible cultural heritage tourism weakness”, “tourism weakness- intangible cultural heritage tourism weakness” and “tourism weakness-intangible cultural heritage tourism prosperity”.
