摘要： Purpose One of the most salient contemporary societal trends is the increasing amount of public-private collaborations. In spite of the increasing awareness of the need to scrutinise the promises of public-private partnership (PPP), there is an important but seldom-asked question: How does the assumed interaction pattern behind PPP correspond with the interaction pattern appearing in empirical studies of the content of business exchange? The purpose of this paper is to shed light on the discrepancy between the expected and actual pattern of interactions in PPPs. Design/methodology/approach The paper presents a specific PPP concerning the construction of a Nya Karolinska (NKS) hospital building, which ended up as an economic and functional disaster. With an interactive approach as point of departure (Hakansson et al. 2009;Waluszewski, Hakansson, Snehota, 2017), this paper investigates a) the interaction pattern of the business landscape expected by policy/politicians in the NKS construction case and b) how the assumed interaction pattern appears in relation to the interaction pattern of the business landscape outlined in empirical studies of exchange, in the business landscape in general and of the construction setting in particular. Findings Given that the public side is neglecting the interactivity and interdependency of the private business setting, the disappointment with the NKS PPP project does not appear as an odd deviation. Rather, as a natural consequence of a public side expecting autonomous actors able to deliver innovation, quality and cost control just because they are exposed to competitive forces - but in reality interfacing with private actors which interests are directed to interdependent investments in place;own and related suppliers'. Social implications The competitive forces of the private setting are by politicians and policy assumed to function in an automatic way;breeding cost efficiency, quality and innovation. Furthermore, there is also an a

摘要： PPP模式众多,只有挑选出最适合污水处理项目的模式,才能保障项目的顺利实施。首先,通过分析污水处理项目特点与PPP模式特征,初步筛选出可供选择的7种PPP模式;然后,从政府视角,建立项目特征、项目风险与收益、政府特征与合作环境、社会资本特征、权属关系5个方面较为全面的污水处理项目PPP模式选择指标体系,采用OWA算子赋权法计算指标权重,并引入灰靶决策理论,构建污水处理项目PPP模式选择模型,通过靶心度对每种PPP模式进行排序;最后,以咸阳市文化体育功能区污水处理项目为例进行验证。结果表明,该模型具有较强的可行性和指导性,可为污水处理PPP项目前期决策提供参考。
