Buying green in U.S. local government: Internal commitment and responsiveness to external pressures
基于210个美国地方政府的调查数据，研究内部承诺（以绿色公共采购制度化阶段衡量）和外部利益相关者压力对绿色采购的影响，发现内部承诺作用更大，且早期制度化阶段更易受外部影响。
Abstract This study investigates how green purchasing in local governments varies as a function of the organization's internal commitment, operationalized by the stage of institutionalization of green public procurement (GPP), and external pressures from various stakeholder groups. GPP, a value‐based innovation justified on the grounds of intergenerational equity, is an important tool governments can use to mitigate the adverse effects of climate change. Survey data from 210 U.S. local governments reveal that while both external and internal factors are strong predictors of buying green, internal commitment matters relatively more. We also find that earlier stages of GPP institutionalization are more conducive to external influence, albeit the effect differs among stakeholders. Local governments tend to be more likely to buy green when nudged by nonprofits and interest groups, and less so when offered financial incentives by the federal government.
