Determinants of local government innovation: the case of green public procurement in the United States

Abstract

PurposeGreen public procurement (GPP) may be a viable solution and an innovative policy tool for public managers to address complex environmental issues facing communities globally. Given their substantial purchasing power, local GPP initiatives and success can accelerate a transition toward a more sustainable society through governments' influence over the private sector. The study's central research question is: What are the factors associated with US local governments' engagement with GPP practices?Design/methodology/approachThis research applies the Mohr's (1969) model of motivations, obstacles and resources (MOR) and draws on original, comprehensive and national survey data collected in collaboration with NIGP: The Institute for Public Procurement to explain adoption of GPP as an innovative policy tool. To ensure the robustness of the findings, the data are analysed by running two types of regression – ordinal logistic and negative binomial – using two different operationalizations for the dependent variable, a GPP scale (ordinal) and a GPP scorecard (count).FindingsThe decision surrounding GPP adoption is ultimately driven by organizations’ strategic visions, organizations’ familiarity with the GPP concept and practices, and mandates from the federal government through funding mechanisms.Originality/valueThis study offers guidance to both academic researchers and policymakers in public management and public budgeting and finance on strategies and policy options to expand GPP adoption and utilization.
