  According to Article 15 of the Implementing Regulations of the Bidding and Tendering Law of the People's Republic of China, prequalification announcements and bidding notices for projects that legally require bidding must be published through media designated by the development and reform department under the State Council. Bidding represents a crucial mechanism for market competition, with its greatest advantage being the full embodiment of the "openness, fairness, and impartiality" principles in market competition. Through this procurement method, multiple bidders engage in fair competition to obtain optimal goods, projects, or services at the lowest or lower prices, thereby achieving goals such as enhancing economic and social benefits, improving the efficiency of state fund utilization, and promoting reforms in investment and financing management systems across industries.

  CnOpenData has matched the list of Chinese industrial enterprises (1998-2013) with the bidding entities and winning entities fields in regional bidding data across China, resulting in the creation of the Chinese Industrial Enterprises Bidding Dataset. This dataset covers fields including enterprise name(企业名称), bidding entity(招标单位), winning entity(中标单位), bid opening date(开标日期), province(省份), and city(城市), providing robust data support for related research.
