Study on the network structure characteristics and cross-regional integration of red cultural relics development in Shandong Province

The cross-regional integrated development of red cultural sites is of great significance to promote the integrated development of regional red tourism.This paper constructs the development index of red cultural sites, and comprehensively uses spatial analysis method and social network analysis method to study the network structure and integration relationship of red cultural sites development in Shandong Province. The results show that :①The development of Shandong red cultural sites forms the spatial distribution pattern of Linyi-Jinan-Qingdao “Golden Triangle ”and Yantai-Weihai-Weifang “Silver Triangle”, and the core network connection direction is Jinan-Taian, Jinan-Zibo and Qingdao-Yantai.②The core-periphery structure of the development of red cultural sites is obvious, and the core areas such as Jinan, Linyi and Qingdao have obvious advantages in the network structure, but the connection strength with the periphery area is insufficient, and the radiation driving ability is poor; Jinan is a key node in the regional integration and development of red cultural sites. With the greatest priority, the “one core, two strong and three circles” integrated development pattern of red cultural sites is taking shape.③The level of government support, upgrading of industrial structure, traffic accessibility, geographical distance and the level of information development affect the spatial association and integrated development of red cultural sites in Shandong Province.
