How does the spatial interaction between tourist destinations and tourist source areas occur?

Complementarity, substitutability, and accessibility. According to Baidu Education Network query, the conditions for the spatial interaction between tourist destinations and tourist source areas are as follows:

1. Complementarity: Due to different geographical environments, residents who permanently live in a certain place have perceptions and perceptions of the outside world. There is a gap in feelings or some psychological needs, and there is something in another place that can fill the gap. This filling process can only be completed by being there and cannot be replaced by any other information channels or methods. These two places are complementary. Complementarity arises from differences in geographical environments. Complementarity is the basic condition for the spatial interaction of tourist destinations to be realized.

2. Substitutability: Substitutability means that two tourist destinations of the same or similar nature can replace each other. Complementarity exists between two tourist destinations with different properties, and the result of complementarity is the formation of tourist flow; Substitutability exists between two tourist destinations with the same nature, and the result of substitution is a complete transfer of the direction of passenger flow in the same tourist source place Or cause diversion.

3. Accessibility: Accessibility is a decisive factor in whether the spatial interaction of a tourist destination can be realized. Mainly refers to the traffic conditions in tourist destinations. The standard of good accessibility is "can come in, can go out, and can disperse". There should be convenient transportation conditions between complementary tourist destinations. Tourist reception areas must have reception conditions for tourists to stay. There are no natural or man-made obstacles for tourists to enter the tourist reception area. Such as natural disasters, security, foreign policy, etc.
