Developing four-season tourism product chains through spatial regional linkages in Quang Ninh Province

Quang Ninh Province possesses diverse tourism resources, yet tourism remains strongly affected by seasonality, resulting in uneven tourist flows and inefficient resource utilization. This study proposes tourism product chains linking Ha Long, Cam Pha, Van Don, and Co To based on seasonal complementarity to promote year-round tourism. Using literature review, comparative analysis, SWOT analysis, and a seasonality matrix, the study finds that differences in resources, tourism products, and seasonal characteristics among the four areas create favorable conditions for integrated product chains. Such linkages can extend visitor stays, disperse tourist flows, and improve resource utilization. The study proposes four tourism product chains and related policy implications to strengthen regional cooperation and enhance the competitiveness of Quang Ninh as a four-season destination.
