Measuring the Social Impact of Infrastructure Projects: The Case of Gdańsk International Fair Co.Journal of Entrepreneurship, Management and Innovation, 13(4), 25-422299-7326http://hdl.handle.net/11199/10362Efficient infrastructure is a prerequisite of, and critical to, development. Only some projects generate a positive rate of return, but all of them should generate positive non-economic impacts and contribute social gains. Social impact is considered as a consequence or effect of decisions or interventions which lead to development. It can also be considered as a social consequence of development. The main problem of social costs and benefits is that the impact is difficult to predict and quantify and can be taken into account differently by authorities, decision makers and project developers. The main purpose of the paper is to identify and demonstrate a concept of the social impact of infrastructure projects. The principal methods used are a review of existing social science literature and surveys based on focus group interviews, devoted stakeholders of infrastructure projects, and their involvement at different stages of the project. The expected result is a set of outputs and outcomes which demonstrates social impacts (costs and benefits) related to stakeholders’ groups of the analyzed project.en-USopen accessAttribution-ShareAlike 3.0 Polandinfrastructure project, social impact, cost and benefit analysisarticle
