Nowadays industrial environment often happens to grow, merger, eliminate or collaborate. Each of procedures is important base on organizational bionomics. However, domestic researches on organizational bionomics background are still limited which cause my research use organizational bionomics as my basic theory. In addition to grow vigorously with network that impels tourism to establish travel web sites. These web sites are as different as before. These web sites are the prime object of nonprofit-making. The government or private travel web sites are almost nonprofit which improving tourism local as their prime purpose. How about the effects when these different qualitative travel web sites appear? Between profit and nonprofit travel web sites what effects they exert an influence to each other, such as mutualism, parasitism, commensalisms and competition .Then, I investigate thoroughly correlate industries with travel web sites include the same or the different business such as airplanes, hotels, restaurants, rental cars, websites, and so on, that have interaction with travel web sites. For this reason, I found that profit and nonprofit travel websites control opportunities between environment and industries changed and develop themselves resources, then they develop the business strategies to make advantages of competition by qualities of travel web sites. However, I stand on organizational bionomics points can discover that all profit travel web sites parasitize on all of nonprofit travel web sites, and travel web sites have many interdependent relationships with correlative tourism, then travel web sites use the correlative tourism to recover their lack of resources. Finally, I use Co-evolution perspective to find the evolution process of ecological system of travel web sites, that changes of environment and appearance of new technology make the ecological system to change, especially the most correlative industries must make new business strategies, or they will die very easy. Therefore, I hope that my investigation can refer the consultation for later travel web sites to make business strategies.
