Abstract: In the era of new development, the coordinated development of Beijing, Tianjin and Hebei is an important part of China's
national regional development strategy.The coordinated development of industries in the three places is the core driving force for
regional integration. Currently, the integration and coordination of the cultural, sports, and tourism industries have become an
important force and means for the development of the Beijing-Tianjin-Hebei region. Based on the Chinese regional input-output tables
of 2012 and 2017, this paper analyzes the backward and forward linkage relationships and their evolutionary characteristics between
the cultural, sports, and tourism industries in the Beijing-Tianjin-Hebei region and various sectors of the national economy from the
perspectives of the whole national economy, the three major industries, and the subdivided industries. The study finds that both the
influence coefficient and the inductance coefficient of the cultural, sports, and tourism industries in the Beijing-Tianjin-Hebei region
show an upward trend, but the influence coefficient is higher than the inductance coefficient, indicating that these industries are driven by demand rather than supply. The backward and forward linkages with the primary industry are both weak; the backward linkages with the secondary industry have significantly decreased in Beijing and Tianjin but have noticeably increased in Hebei. The forward linkages have significantly decreased in Beijing and Hebei while noticeably increasing in Tianjin; the backward linkages with the tertiary industry are becoming stronger, while the forward linkages have sharply decreased in Beijing but increased in Tianjin and
Hebei. The Beijing-Tianjin-Hebei region has high backward dependence on eight types of industries such as domestic leasing and
business services, paper printing and cultural, educational, sports goods, and cultural, sports, and tourism products. Beijing tends to
provide forward supply to service sectors such as the cultural, sports, and tourism industries and public management, while Tianjin and Hebei tend to provide forward supply to manufacturing sectors such as metal smelting and rolling products and chemical products. The research is of great significance for promoting the regional development strategy and policy formulation in the Beijing-Tianjin-Hebei region. It not only provides scientific data support for the high-quality development of the cultural, sports, and tourism industries in the Beijing-Tianjin-Hebei region but also provides valuable decision-making references for the implementation of coordinated development strategies in these regions and other areas of China.
