Unlocking Potential: Macro Insights Into the Evolution of a Multi-Destination Tourism Innovation Network

This study investigates the evolution of a multi-destination tourism innovation network, focusing on the city destination as the unit of analysis. We analyzed a 21-year panel dataset of China’s Yangtze River Delta’s tourism innovation network. Results show that the network has evolved from simplicity and looseness to complexity and compactness. Geographical proximity, differences in tourism development foundations, research institutes, and research investments have a positive impact on network evolution, while economic and technological differences exert a negative influence, albeit with varying degrees of impact at different stages. Notably, the convergence of regional economies emerges as a critical driver of network connections. The study broadens the scope of tourism innovation research from a macro perspective. Findings suggest that developed cities should lead regional tourism innovation, promote openness, and engage with less-developed cities, while local governments within the network should support coordinated growth and invest in inter-city transportation and developing tourism resources.
