  Auction is a spot trading method wherein auction houses specializing in auction businesses accept consignments from goods owners. Within specified timeframes and venues, following established bylaws and rules, they display auction items to prospective buyers, conduct public bidding, and ultimately sell the goods to the highest bidder.

  Auctions were introduced to China in the 1870s and have experienced ups and downs since. After 1985, with the deepening of China's economic system reform, auctioning rapidly revived and developed. As living standards continue to rise and investment philosophies evolve, China's auction industry—an important component of modern services—will gain broader survival space and greater development opportunities. To regulate the auction market, strengthen enterprise management, and promote the healthy development of the auction industry, China implements stringent supervision and regulatory measures for auction enterprises.

  CnOpenData presents national auction industry enterprise data, covering company names (including branches), locations, business scopes, registered capital, premises area, employee counts, and other information across the country. Furthermore, longitude and latitude coordinates of locations are provided to better support relevant academic research.
