As the internet and smart phones have taken over the role of booking trips, hotels and tickets for travelers, which cities in China are pioneers when it comes to online booking?

The China Tourism Academy and leading travel services provider Ctrip jointly released a report recently, ranking over 70 cities around the country based on the number of bookings of tourism products and level of consumption.

Three metropolises – Shanghai, Beijing and Guangzhou –top the ranking, but the business in second-and-third-tier cities is showing great potential, according to the report.

The study is based on 250 million Ctrip users and more than 10,000 travel agencies.

Here are the top 10 Chinese cities with "internet plus tourism."
