“…In terms of theoretical research, most scholars mainly discuss the theoretical basis of government green procurement from the aspects of new institutional economics, environmental economics, environmental management, and sustainable development theory [5]. Specifically, government green procurement activities are mainly guided by externality theory, green supply chain management theory, sustainable development theory, and stakeholder theory [6][7][8]. At present, the theoretical research on green procurement in China is mainly for government procurement and manufacturing procurement; the research content mainly focuses on green supplier selection [9][10][11][12][13][14][15], green procurement management mode [16], restriction factor analysis [17][18][19], legal system [20][21][22], policy recommendations [23][24][25][26], etc., while the research on green supplier selection mainly focuses on goods [27], and research focuses on projects of government green procurement is rare.…”
