Evidence Based Policy Making

–Its Present and Future–

Abstract

This paper reviews “Evidence Based Policy Making”, its philosophy, methods, and application in relation to policy decision making frameworks. The purpose of this paper is to reconstruct a framework for intervention decision making common to EBM and EBPM. We distinguish three stages of decision making: (A) the planning stage, (B) the implementation management stage, and (C) the evaluation and multidimensional feedback stage. Within these stages, different policy decisions are discussed. EBPM does not pay much attention to the construction of dialogue spaces as public spheres. The construction of a public sphere for policy making requires the construction of a variety of registers as social infrastructure by industry, government, and academia, which contain facts in the discourse, states and its changes on the target system, macro-statistics, financial and non-financial information of enterprises, micro-mechanism models of policy scenarios, and so on. It is also necessary to build a register-based public sphere that can use these registers comprehensively.
