Sustainability, Vol. 12, Pages 651: Construction of Bid Evaluation Index System in Government Public Project Green Procurement in China Based on D-S Evidence Theory (Sustainability)

It is of great theoretical and practical significance to construct a bid evaluation index system characterized by green for government public project green procurement. With the combination of sustainable development theory and system theory, and with the goal of government public project procurement as the guide, this paper uses the documentary research method, questionnaire survey method, and expert consultation method to analyze the influential factors of bid evaluation for government public project procurement with the perspective of green development from the aspects of qualification, economy, technology, management, and public welfare and to construct the bid evaluation index system for government public project green procurement; based on Dempster-Shafer evidence theory, using the D-S evidence synthesis method to construct a comprehensive judgment matrix for group decision-making (which effectively solves the problem of synthesizing expert opinions), and combined with the analytic hierarchy process, the index weights are determined. Ultimately, a bid evaluation index system for government public project green procurement is obtained, including 5 first-level indexes, 18 secondary indexes, and 56 tertiary indexes, providing theoretical guidance for the government to implement green procurement in the field of public projects.
