Abstract:
Marine science technology innovation provides power and guarantees for marine eco-civilization construction, which provides direction and material support for marine science technology innovation. Therefore, the coordinated development of the two is of great significance to the marine economy sustainable development in China’s coastal areas. On the basis of clarifying the connotations of marine science technology innovation and marine eco-civilization in China’s coastal areas from 2006 to 2019, the mechanism for their coordinated development was analysed. A comprehensive indicator system based on the connotation of the two was constructed, and the coordinated development relationship was empirically tested using the coupled coordination model and the panel vector autoregressive (PVAR) model. The results show that: 1) the level of China’s coastal marine science technology innovation continues to improve, gradually forming the core of the development of marine science technology innovation in the north, east and south of Shandong, Shanghai and Guangdong; the level of marine eco-civilization development fluctuating upward trend, showing obvious spatial differentiation characteristics. 2) The degree of coordination of marine science technology innovation and marine eco-civilization is growing over time. There is no causal relationship between marine science technology innovation and marine eco-civilization in the northern marine economic circle, but there is a two-way causal relationship between the two in the eastern and southern marine economic circles. 3) Marine eco-civilization shows a significant positive and continuous impact on marine science technology innovation, and marine science technology innovation shows a long-term, continuous, fluctuating, and lagging impact on marine eco-civilization. The overall role of marine eco-civilization on marine science technology innovation is dominant, and there are significant differences in the impact effects of the two major marine economic circles.

Abstract:
Urban tourism is considered a complex system, and multiscale exploration of the organizational patterns of attraction networks has become a topical issue in urban tourism, so exploring the multiscale characteristics and connection mechanisms of attraction networks is important for understanding the linkages between attractions and even the future destination planning. This paper uses geotagging data to compare the links between attractions in Beijing, China during four different periods: the pre-Olympic period (2004–2007), the Olympic Games and subsequent ‘heat period’ (2008–2013), the post-Olympic period (2014–2019), and the COVID-19(Corona Virus Disease 2019) pandemic period (2020–2021). The aim is to better understand the evolution and patterns of attraction networks at different scales in Beijing and to provide insights for tourism planning in the destination. The results show that the macro, meso-, and microscales network characteristics of attraction networks have inherent logical relationships that can explain the commonalities and differences in the development process of tourism networks. The macroscale attraction network degree Matthew effect is significant in the four different periods and exhibits a morphological monocentric structure, suggesting that new entrants are more likely to be associated with attractions that already have high value. The mesoscale links attractions according to the common purpose of tourists, and the results of the community segmentation of the attraction networks in the four different periods suggest that the functional polycentric structure describes their clustering effect, and the weak links between clusters result from attractions bound by incomplete information and distance, and the functional polycentric structure with a generally more efficient network of clusters. The pattern structure at the microscale reveals the topological transformation relationship of the regional collaboration pattern, and the attraction network structure in the four different periods has a very similar importance profile structure suggesting that the attraction network has the same construction rules and evolution mechanism, which aids in understanding the attraction network pattern at both macro and micro scales. Important approaches and practical implications for planners and managers are presented.
