Bidding and tendering refer to transactional methods employed in market economies for the sale/purchase of bulk commodities, contracting of construction projects, and procurement of services. This dual mechanism constitutes two aspects of commercial transactions. After over three decades of development, China has established a comprehensive bidding procurement system covering all domains and administrative levels, significantly expanding the scope of bidding activities, fostering fair market competition, and standardizing procurement practices. With the continuous improvement of legal frameworks, administrative supervision mechanisms, social oversight systems, and market entities' self-discipline mechanisms, the bidding system is poised to achieve broader applications and sustainable development in China.
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 mandatory bidding projects must be published through media designated by the National Development and Reform Commission. As a vital market competition mechanism, bidding maximizes the principles of "openness, fairness, and impartiality" by enabling multiple bidders to compete equitably. This process facilitates the acquisition of optimal goods, projects, or services at minimal costs, thereby enhancing economic and social efficiency, improving the utilization of state funds, and promoting reforms in investment/ financing management systems across industries.
