概要	Regulatory impact analysis (RIA) is a systematic process for appraising the likely costs, benefits and effects of proposed regulation before it is adopted. Promoted by the OECD as a cornerstone of good regulatory governance, it requires governments to define the problem a regulation is meant to solve, set out alternative options including non-regulatory ones, assess the impacts of each against a do-nothing baseline, consult affected parties, and recommend the option that delivers the greatest net benefit. RIA aims to ensure that new rules are evidence-based, proportionate and justified rather than imposed without examination of their consequences.	Stakeholder analysis is a systematic approach to identifying the individuals, groups and organisations affected by or able to affect a policy or program, characterising their interests and influence, and understanding the relationships among them. Reed and colleagues' influential 2009 typology organises the field into three tasks: identifying stakeholders, differentiating and categorising them, and investigating their relationships. The aim is to inform the design, implementation and evaluation of policy by clarifying whose interests are at stake, who holds power, and how to engage them — improving both the effectiveness and the legitimacy of decisions.
