관광산업의 산업간 연계구조에 따른 지역 차이에 관한 연구: 산업연관표를 이용한 가상추출법과 사회네트워크 분석을 중심으로

Given the growing importance of promoting tourism as a key strategy to address the challenges of Local Extinction Risk and Population Reduction, this study examines the economic impacts of the tourism industry and explores its inter-industry linkages. To clarify this, this study analyzes the differences in the economic ripple effects among intertwined industries across six metropolitan regions using input–output analyses. The methodology applies three approaches: Input-Output analysis (combined with the hypothetical extraction method), network analysis (based on proximity) and inter-city centrality. The results of the analyses are as follows. First, while the tourism industry depends on regional demand, it also exerts a strong effect on generating successive production linkages within the regional economy. Second, the results from the degree centrality analysis (Social Network Analysis) were found to be consistent with those derived from the hypothetical extraction method. Furthermore, the industries most closely associated with tourism were identified as C01_Food and Beverages, G_Wholesale, Retail Trade with Brokerage Services, and L_Real Estate Services. Third, the characteristics of the tourism industry's linkage structure were able to be identified. Therefore, strategies need to be explored to integrate tourism with the region's specialized industries in order to revitalize local tourism.
